WEBVTT - TechStuff Overclocks a CPU 0:00:00.280 --> 0:00:02.840 Brought to you by the reinvented two thousand twelve camera. 0:00:03.160 --> 0:00:08.920 It's ready. Are you get in touch with technology with 0:00:09.000 --> 0:00:17.920 tech Stuff from how stuff dot com. Well, hello there everyone, 0:00:17.960 --> 0:00:20.279 and welcome to tech stuff. My name is Chris Poulette 0:00:20.280 --> 0:00:22.480 and I am an editor how stuff works dot Com. 0:00:22.480 --> 0:00:25.439 Sitting across from me, as always is seen your writer 0:00:25.520 --> 0:00:28.080 Jonathan Strickland. If I am out of my mind, it's 0:00:28.120 --> 0:00:32.199 all right with me, thought Moses Herzog. All right, I 0:00:32.320 --> 0:00:35.280 was a short one today, Yes, And today to start 0:00:35.320 --> 0:00:38.440 off our episode, we have a little Facebook feedback you be. 0:00:39.280 --> 0:00:41.720 This comes from Brian, who says I've been listening to 0:00:41.760 --> 0:00:44.240 you guys since almost the beginning. Keep up the great work. 0:00:44.479 --> 0:00:46.440 I was wondering if you could do a podcast about 0:00:46.440 --> 0:00:48.479 over clocking. You can talk about what it is, how 0:00:48.479 --> 0:00:50.360 it works, in the pros and cons of it. I've 0:00:50.400 --> 0:00:52.680 had some experience myself and can tell you it's well 0:00:52.720 --> 0:00:56.080 worth it. Can't wait to listen to your next podcast. Well, Brian, 0:00:56.400 --> 0:00:59.160 this one goes out to you. Now. We've talked a 0:00:59.200 --> 0:01:02.200 little bit about over clocking in past episodes, particularly Anything 0:01:02.200 --> 0:01:05.480 where we talked about CPUs and clock cycles. But but 0:01:05.600 --> 0:01:08.840 let's let's kind of go back and talk about what 0:01:08.920 --> 0:01:11.800 a clock cycle is and why it's important and what 0:01:12.040 --> 0:01:16.760 overclocking actually means. Yes, now, this is something we talk 0:01:16.800 --> 0:01:20.080 about a long time ago, A long long time ago, 0:01:20.120 --> 0:01:22.960 we talked about the Mega Hurt Smith and you know, 0:01:23.080 --> 0:01:26.120 the giga Hurt Smith, about the the speed of the 0:01:26.160 --> 0:01:29.520 processor and what it means, and how it's really not 0:01:29.600 --> 0:01:32.160 necessarily all that important. In fact, that it's kind of 0:01:32.200 --> 0:01:36.160 funny looking at computers now, um, because now that the 0:01:36.240 --> 0:01:39.680 dual core and quad core processors and and well let's 0:01:39.680 --> 0:01:42.480 just say multi core processors, um, some of them look 0:01:42.520 --> 0:01:45.560 like they're going backward because you'll see, you know, a 0:01:45.880 --> 0:01:48.080 two gigga Hurts processor and you go, wait a minute, 0:01:48.080 --> 0:01:50.600 the one I have now is a three point two Yeah, 0:01:50.600 --> 0:01:52.480 it is a three point two gigga Hurts. Well, yeah, 0:01:52.560 --> 0:01:55.880 because it's got multiple cores processing, it's able to do this. 0:01:55.960 --> 0:01:59.040 But the clock speed is is basically the rate at 0:01:59.080 --> 0:02:03.600 which a process is handling instructions. Very good. Yes, um. 0:02:03.640 --> 0:02:08.760 I actually saw a pretty interesting analogy on a Yale website. 0:02:08.800 --> 0:02:12.799 This was written by H. Gilbert, and Gilbert said that 0:02:13.200 --> 0:02:15.639 think of it like a high school, right, So you're 0:02:15.680 --> 0:02:19.400 in class and then the bell rings, and that signals 0:02:19.440 --> 0:02:22.000 the end of class. So you leave, alright, and the 0:02:22.120 --> 0:02:24.640 second bell rings and you have to go to your 0:02:24.639 --> 0:02:27.720 next class. So those two bells, he says, think of 0:02:27.760 --> 0:02:30.040 that as a clock cycle. The first bells a tick 0:02:30.080 --> 0:02:33.160 and the second bells of talk, and the entire school 0:02:33.600 --> 0:02:36.720 reacts to those bells. It's not like one class gets 0:02:36.760 --> 0:02:39.639 a bell and then three minutes later another class gets 0:02:39.639 --> 0:02:42.960 a bell. It goes across the entire school. So, uh, 0:02:43.200 --> 0:02:45.640 think of a clock cycle on a on a CPU 0:02:45.760 --> 0:02:47.480 is the same sort of thing, except in steps. Students, 0:02:47.520 --> 0:02:52.320 we're talking about data ones and zeros, so ones and zeros, 0:02:52.360 --> 0:02:55.080 and and that at every clock cycle, ones and zeros 0:02:55.120 --> 0:02:59.360 are moving around. And essentially every task you want a 0:02:59.400 --> 0:03:03.320 computer to do requires a certain number of cycles. Uh. 0:03:03.440 --> 0:03:07.120 Some tasks only require one cycle, and some will require 0:03:07.200 --> 0:03:10.240 multiple cycles because the task actually has more steps than 0:03:10.320 --> 0:03:13.360 what you might first imagine. And this changes over time. 0:03:13.440 --> 0:03:17.639 I should add back, you know, several years ago, many 0:03:17.720 --> 0:03:20.720 years ago, a couple of decades now, adding two numbers 0:03:20.720 --> 0:03:26.120 together might take six or eight clock cycles to complete. Uh, 0:03:26.160 --> 0:03:28.959 and today it might take one clock cycle. So it's 0:03:28.960 --> 0:03:31.799 become more efficient. So that's one way that CPUs have 0:03:31.880 --> 0:03:34.000 sped up over time. But another is that we've actually 0:03:34.000 --> 0:03:36.360 managed to fit more clock cycles in per second. And 0:03:36.440 --> 0:03:40.040 that's the speed we talk about with processors. That's how 0:03:40.040 --> 0:03:44.840 many clock cycles or pulses if you prefer, go through 0:03:44.920 --> 0:03:49.400 the the that particular element on your computer every second. 0:03:49.760 --> 0:03:53.119 So if you hear about a here's a dinosaur. Let's 0:03:53.120 --> 0:03:55.760 say you hear about a five hundred mega Hurts processor. 0:03:56.320 --> 0:04:01.160 That means five hundred million clock cycles per second go 0:04:01.240 --> 0:04:05.839 through that that CPU. All things considered, that's that's pretty fast, right. 0:04:05.880 --> 0:04:07.680 But you know, then we talk about things like a 0:04:07.680 --> 0:04:10.440 two point for giga Hurts processor that's two point four 0:04:10.480 --> 0:04:14.440 billion clock cycles per second, which is even much faster, 0:04:14.760 --> 0:04:20.360 and they get faster than that obviously, But that's so 0:04:20.360 --> 0:04:22.880 so when we're talking about processor speed, really talking about 0:04:22.960 --> 0:04:26.039 the amount of work a processor can do within a 0:04:26.040 --> 0:04:29.240 certain amount of time, and faster processors can do more 0:04:29.320 --> 0:04:32.800 work in that in that timeframe. So the five hundred 0:04:32.800 --> 0:04:37.599 mega Hurts processor can do five hundred million uh can 0:04:38.400 --> 0:04:42.560 not five million tasks, but can use five million clock 0:04:42.600 --> 0:04:45.680 cycles toward tasks in a second, whereas the two point 0:04:45.720 --> 0:04:48.280 for giga Hurts does two point for billion clock cycles 0:04:48.320 --> 0:04:54.080 toward tasks in a second. So yeah, that's that's essentially 0:04:54.120 --> 0:04:58.120 the speed element. Now, uh CPUs are not the only 0:04:58.160 --> 0:05:00.479 thing that work on cycles, by the way, US want 0:05:00.480 --> 0:05:03.240 to make that clear when we do talk about clock cycles. 0:05:04.080 --> 0:05:08.600 Other elements like memory and io devices also operate on cycles. 0:05:08.640 --> 0:05:13.320 And all of this is controlled ultimately by the motherboard. Yes. Now, 0:05:13.680 --> 0:05:17.400 if you're wondering how a you know, how they come 0:05:17.440 --> 0:05:22.760 out with these chips, UM, Well it's it's it's sort 0:05:22.760 --> 0:05:25.600 of controlled UM. If you think about it. Let's say, 0:05:25.680 --> 0:05:31.800 let's take Jonathan's five megahertz processor. UM. The manufacturer has 0:05:31.839 --> 0:05:35.720 you know, knows something about the range at which this 0:05:35.800 --> 0:05:39.640 chip can operate. UM. It can operate more slowly than that, 0:05:39.760 --> 0:05:43.080 it can operate more quickly than that. But what goes 0:05:43.160 --> 0:05:46.520 on is in the process of building this and testing 0:05:46.520 --> 0:05:50.160 this chip, they know roughly about how much electricity it's 0:05:50.200 --> 0:05:53.880 going to use and about how hot it's gonna get. UM. 0:05:53.920 --> 0:05:58.520 Many many of us UH have an idea of what 0:05:58.640 --> 0:06:02.200 happens when you're compute it or overheats. UM. It will 0:06:02.360 --> 0:06:07.080 seize up eventually UM and decrease the operating life of 0:06:07.120 --> 0:06:10.880 the computer overall. Too If it gets too hot too frequently. Yeah. 0:06:11.080 --> 0:06:14.719 So the thing is the manufacturer of the processor is 0:06:14.720 --> 0:06:17.000 going to go, well, okay, this is this is a 0:06:17.040 --> 0:06:20.760 good range. This is about what it's gonna do. And essentially, yeah, 0:06:20.760 --> 0:06:25.880 and essentially it'll runs as fast as this without going 0:06:26.000 --> 0:06:30.120 nuts and requiring you know, a a to be immersed 0:06:30.160 --> 0:06:33.000 in liquid nitrogen to keep it cold. We'll get to 0:06:33.080 --> 0:06:35.960 that right, right, So this is under normal operating conditions. 0:06:36.000 --> 0:06:37.960 This is about how fast this chick is going to run. 0:06:38.040 --> 0:06:41.240 Let's say it's five mega hurts and and there are 0:06:41.279 --> 0:06:48.000 instructions um in the computer actually written into ROM that 0:06:48.040 --> 0:06:51.920 will keep it from doing more than that. Yeah. Essentially, 0:06:51.960 --> 0:06:54.880 you've got two elements that determine the speed. You have 0:06:54.920 --> 0:07:00.200 the motherboard which provides a baseline speed, and those to 0:07:00.279 --> 0:07:04.240 be around one hundred thirty three, one sixty six or 0:07:04.279 --> 0:07:08.039 two hundred mega hurts. And then you have a multiplier 0:07:08.400 --> 0:07:12.520 on the CPU itself. So for the five hundred megahurts 0:07:12.600 --> 0:07:15.400 machine we were talking about, the multiplayer might be five 0:07:15.560 --> 0:07:18.480 and the motherboard provides one hundred mega hurts. So the 0:07:18.520 --> 0:07:21.800 clock inside the CPU is going to run at five 0:07:21.840 --> 0:07:25.600 times the speed of the clock on the motherboard. So 0:07:25.680 --> 0:07:29.040 the motherboard sets the pace, the CPU multiplies that pace, 0:07:29.320 --> 0:07:32.600 and that's where you get your processor clock speed. So 0:07:32.840 --> 0:07:35.960 the five multiplayer times the one hundred mega hurts, that's 0:07:35.960 --> 0:07:38.960 where you get your five hundred mega hurts. Now, if 0:07:39.040 --> 0:07:46.000 you had a a multiplayer that was say twenty four 0:07:46.800 --> 0:07:49.080 times one hundred, well that's where you get the two 0:07:49.080 --> 0:07:53.040 point four giga hurts because you get the two thousand, 0:07:53.080 --> 0:07:56.760 one four hundred, and then that two thousand, four hundred 0:07:56.760 --> 0:08:00.400 mega hurts is the same as two point four gig hurts. Um. 0:08:00.440 --> 0:08:03.560 So the multiplayers tend to be difficult to change with 0:08:03.680 --> 0:08:06.720 most processors, not all, but a lot of processors have 0:08:07.080 --> 0:08:10.160 the manufacturers have locked down that multiplayer in order to 0:08:10.200 --> 0:08:14.280 prevent people from pushing it too hard and causing problems 0:08:14.280 --> 0:08:18.280 down the line. Yeah, because ultimately the majority of us 0:08:18.280 --> 0:08:21.280 are going to buy our computers. We're gonna set it up, 0:08:21.400 --> 0:08:23.320 do our work on it, play games on it, do 0:08:23.400 --> 0:08:25.480 whatever it is that we're gonna do on it. And 0:08:26.360 --> 0:08:29.720 the point is we want it to last. Uh, most 0:08:29.720 --> 0:08:31.480 of us can't just go buy a new computer. And 0:08:31.480 --> 0:08:33.040 if we don't know what we're doing as far as 0:08:33.080 --> 0:08:37.160 over clogging, um, you know, we're just gonna we want 0:08:37.160 --> 0:08:39.160 this machine to last us a good long time and 0:08:39.200 --> 0:08:41.680 if you use it under normal circumstances, unless the fan 0:08:41.760 --> 0:08:45.880 breaks or some the cooling mechanism breaks. Even in computers 0:08:45.880 --> 0:08:48.240 with no fans, let's say, uh, you know one of 0:08:48.280 --> 0:08:50.640 the older Imax that they made a point of putting 0:08:50.640 --> 0:08:53.160 no fan in. If you clogged up the air vents 0:08:53.200 --> 0:08:57.280 with something dust, a blanket, it will overheat and the 0:08:57.320 --> 0:09:00.760 computer will die or it will shorten the life of it. Um, 0:09:01.080 --> 0:09:03.360 So be unsteady and old, crash a lot, that kind 0:09:03.400 --> 0:09:06.079 of thing. So to the point of the manufacturer setting 0:09:06.280 --> 0:09:10.320 a clock speed a default clock speed is is basically 0:09:10.360 --> 0:09:13.480 to make it a motherboard, a chip on a motherboard 0:09:13.480 --> 0:09:16.480 that it's gonna last the average computer user a good 0:09:16.480 --> 0:09:20.280 long while years hopefully, I'd say that's the that's the point. 0:09:20.320 --> 0:09:22.559 I'd say that's true in the majority of cases. There 0:09:22.600 --> 0:09:27.880 are a few cases where manufacturers have developed one chip 0:09:28.000 --> 0:09:31.960 to go in a line of computers and have put 0:09:31.960 --> 0:09:37.360 in essentially a a an artificial limit to how fast 0:09:37.440 --> 0:09:40.240 that processor can go per model. So let's say that 0:09:40.280 --> 0:09:44.840 I've got a selection of computers, um, and we're gonna say, 0:09:44.880 --> 0:09:47.360 we're gonna call A, Model A, B, C, and D, 0:09:48.320 --> 0:09:51.200 and all four of these have the same processor in them, 0:09:51.720 --> 0:09:54.240 but I've put limitations on it so that Model A 0:09:54.520 --> 0:09:57.839 can only go at five hundred mega hurts, and Model 0:09:57.880 --> 0:10:00.600 B as a giga hurts, and and UM models see 0:10:00.600 --> 0:10:02.720 as two gig hurts, and Model D is like two 0:10:02.720 --> 0:10:05.640 point four gig hurts, and two point four is really 0:10:05.720 --> 0:10:08.040 where the sweet spot is. But I've put in these 0:10:08.160 --> 0:10:11.720 artificial limitations on the previous ones. The reason for that 0:10:11.720 --> 0:10:14.400 would be I only have to manufacture one chip, and 0:10:14.440 --> 0:10:18.559 I can create devices for multiple markets. Because there's some 0:10:18.600 --> 0:10:20.480 people are gonna be out there who are saying, I 0:10:20.520 --> 0:10:22.280 need a computer, but I don't need it to do 0:10:22.320 --> 0:10:26.160 the latest stuff, or I can't afford to buy a 0:10:26.160 --> 0:10:28.920 computer that has like the top level technology in it, 0:10:29.440 --> 0:10:31.840 but I'm gonna go and get this base model instead, 0:10:32.040 --> 0:10:33.640 And then they're gonna be the up people on the 0:10:33.640 --> 0:10:36.720 other side of it, saying I want the fastest machine 0:10:36.760 --> 0:10:39.120 I can possibly get, so they're gonna go for the 0:10:39.120 --> 0:10:41.480 other one. Well, they can create a whole range of 0:10:41.520 --> 0:10:45.000 computers meeting all of these demands using the same chip 0:10:45.160 --> 0:10:47.760 if they put those limitations in place, and in some 0:10:47.800 --> 0:10:51.679 cases you can't really get around the multiplier limitation without 0:10:51.960 --> 0:10:56.880 some really deep knowledge and risking ruining your computer. However, 0:10:57.360 --> 0:11:01.439 what you can do has changed a rate on the 0:11:01.480 --> 0:11:05.959 motherboard itself, and you do that through the BIOS system. 0:11:06.000 --> 0:11:09.239 And before we before we get into technical detail, um, 0:11:09.240 --> 0:11:12.760 overclocking is the process that we're talking about. Now. This 0:11:12.840 --> 0:11:18.280 means that you're increasing the limit at which the chip 0:11:18.960 --> 0:11:23.280 can process instructions. Yeah, it's essentially pushing more clock cycles 0:11:23.320 --> 0:11:26.920 in per second than what the chip was recommended for. 0:11:27.760 --> 0:11:31.200 And we should say it really is a recommendation because, uh, 0:11:31.520 --> 0:11:33.559 like Chris was saying, most of these chips, I mean 0:11:33.640 --> 0:11:37.559 almost all chips that come out have the capacity to 0:11:37.640 --> 0:11:40.960 operate over what they are rated for. So at two 0:11:41.040 --> 0:11:44.800 point four gigahertz processor can actually work faster than that. 0:11:44.880 --> 0:11:47.480 In fact, usually it's around five to ten percent faster 0:11:47.600 --> 0:11:50.240 than what the rating is for. So if you are 0:11:50.240 --> 0:11:54.480 still five to tempercent faster without running the risk of 0:11:55.559 --> 0:11:58.439 causing damage to your computer, so you might be able 0:11:58.520 --> 0:12:02.400 to boost your computer performance by or at least the 0:12:02.640 --> 0:12:05.840 processing speed by five or ten percent without having to 0:12:05.880 --> 0:12:10.320 worry about additional concerns. Once you go beyond that, then 0:12:10.360 --> 0:12:12.920 you have to start looking into creative ways of managing 0:12:12.920 --> 0:12:15.480 your computer so that it doesn't you know, just crash 0:12:15.520 --> 0:12:18.520 on you. And even if you do just overclock your 0:12:18.559 --> 0:12:20.400 computer a little bit, there is a chance that stuff 0:12:20.440 --> 0:12:22.880 will crash because sometimes programs just don't work very well 0:12:22.880 --> 0:12:28.640 with overclocked processors. Um. Yeah, So that's the basis. Though. 0:12:28.760 --> 0:12:32.280 Overclocking means that you're pushing through more clock cycles per second. 0:12:33.120 --> 0:12:35.880 And uh, before we again, before we get into too 0:12:35.960 --> 0:12:38.000 much detail, this is not the kind of thing that 0:12:38.040 --> 0:12:41.320 you want to do casually and figure, oh, you know what, 0:12:42.480 --> 0:12:44.480 let's just go and try this. You want to think 0:12:44.559 --> 0:12:48.719 about how what happens if it doesn't work, because if 0:12:48.720 --> 0:12:51.959 you don't follow the instructions carefully. Um. And we're not 0:12:51.960 --> 0:12:54.200 going to give you a lot of instructions because there's 0:12:54.200 --> 0:12:57.079 a lot depend upon what the processor is. So yeah, 0:12:57.360 --> 0:12:59.560 but the thing is, if you're not very careful, you 0:12:59.559 --> 0:13:03.880 could amage your computer permanently. And most of the time, 0:13:03.920 --> 0:13:07.200 if you try to overclock your processor, you're violating a warranty. 0:13:07.400 --> 0:13:09.599 So if you if you do damage your computer, you 0:13:09.640 --> 0:13:11.520 don't have any recourse to get it fixed by the 0:13:11.520 --> 0:13:14.240 manufacturer because they're gonna say, hey, you did this thing 0:13:14.280 --> 0:13:17.119 you weren't supposed to do. Therefore, we have no obligation 0:13:17.160 --> 0:13:21.240 to help you out. So so if you do this, 0:13:21.400 --> 0:13:23.240 make sure you you put some thought into it and 0:13:23.240 --> 0:13:25.640 make sure this is something you feel up to and 0:13:25.679 --> 0:13:28.199 that you're you're willing to try before you really give 0:13:28.240 --> 0:13:30.720 it a shot if you want to. Uh, it could 0:13:30.760 --> 0:13:33.319 be very very profitable for you if you're looking for 0:13:33.360 --> 0:13:37.000 a faster machine and you have the uh, the ability, 0:13:37.040 --> 0:13:39.040 and the you know, the money if you need it. 0:13:39.559 --> 0:13:41.640 But we can get into that now, right right. And 0:13:41.679 --> 0:13:44.440 the reason why you would want to overclock your machine 0:13:44.440 --> 0:13:46.680 in the first place is that it allows you to 0:13:47.360 --> 0:13:52.080 run more advanced programs at a faster rate without having 0:13:52.120 --> 0:13:54.760 to buy a new processor or a new machine. That's 0:13:54.840 --> 0:13:58.000 that's the big attraction for a lot of gamers out there. 0:13:58.080 --> 0:14:00.520 They'll they'll buy a good gaming rig and then they 0:14:00.559 --> 0:14:04.040 overclocked their processors so that they can run games at 0:14:04.120 --> 0:14:07.880 at the highest settings without any slowdown and to have 0:14:08.000 --> 0:14:11.200 you know, the best performance in their game. UH. And 0:14:11.320 --> 0:14:15.439 also it means that you know they they're essentially getting 0:14:16.040 --> 0:14:19.520 higher like they're getting the equivalent of a faster processor, 0:14:19.760 --> 0:14:22.960 but they're buying a less expensive one. Right. So if 0:14:22.960 --> 0:14:25.200 there were say a two point eight processor out there, 0:14:25.200 --> 0:14:27.360 in a three point two processor out there, and you 0:14:27.440 --> 0:14:29.480 knew you could overclock your two point eight so that 0:14:29.560 --> 0:14:32.960 would equal or exceed the three point two, you say, well, 0:14:32.960 --> 0:14:35.000 why would I spend the extra money getting the three 0:14:35.040 --> 0:14:36.720 point two when I could get the two point eight 0:14:36.720 --> 0:14:40.800 and just overclocked that puppy. And of course there's the 0:14:40.880 --> 0:14:46.320 maker's reason because they can. Yeah, yes, there's always that too. 0:14:46.320 --> 0:14:48.960 It's just like, hey, I I have the ability to 0:14:49.040 --> 0:14:51.720 fiddle with my computer settings. Gosh darn it, that's what 0:14:51.760 --> 0:14:55.200 I'm gonna do. So you were talking a moment ago 0:14:55.520 --> 0:15:00.240 about the BIOS, the basic input output system. Yes, now, 0:15:00.280 --> 0:15:03.680 this is a part of when you boot up your computer. 0:15:03.760 --> 0:15:06.440 It goes through the BIO set up, and part of 0:15:06.480 --> 0:15:09.800 that BIO set up is the motherboard checks the processor, 0:15:10.240 --> 0:15:12.320 sees what kind of processor it is and what the 0:15:12.360 --> 0:15:17.120 recommended settings are, and then goes into that recommended setting 0:15:17.240 --> 0:15:21.120 for the speed that the motherboard provides as later on 0:15:21.280 --> 0:15:26.000 multiplied by the processor. Uh. The thing is, you can 0:15:26.040 --> 0:15:29.840 actually interrupt the BIOS set up system and manually change 0:15:29.880 --> 0:15:33.280 those settings. So let's say that it was set at 0:15:33.440 --> 0:15:36.000 one hundred megahurts. You could up it up to one 0:15:36.080 --> 0:15:38.920 thirty three or one sixty six or two hundred. Although 0:15:39.560 --> 0:15:44.160 you know the more you boost this the the closer 0:15:44.200 --> 0:15:49.240 you ride that dangerous edge of possibly ruining your machine. 0:15:49.520 --> 0:15:51.320 It's like like getting in a car and pushing it 0:15:51.360 --> 0:15:53.640 faster than it was meant to go. It can start 0:15:53.640 --> 0:15:57.600 to shake apart. Most of the instructions I read in 0:15:57.880 --> 0:16:00.640 the process of doing research for this podcast suggested that 0:16:00.680 --> 0:16:05.600 you would tinker with the multiplier and basically, rather than 0:16:05.920 --> 0:16:08.320 going how high can I push this up, let's turn 0:16:08.360 --> 0:16:10.800 it all the way up, what they suggest doing is 0:16:11.320 --> 0:16:14.440 taking it up a couple of notches. Essentially. Again, read 0:16:14.440 --> 0:16:18.680 the instructions carefully for for the the system that you have, 0:16:18.800 --> 0:16:21.040 and then and then the materials that you've got on him. 0:16:21.120 --> 0:16:25.120 But I'm oversimplifying. For the case of explanation, you might 0:16:25.320 --> 0:16:28.160 crank it up a notch or two notches and test 0:16:28.200 --> 0:16:30.000 it see how it runs. Does it look like it's 0:16:30.040 --> 0:16:32.640 doing all right? Does it look like it's behaving oddly 0:16:32.680 --> 0:16:35.680 if the applications all crashing, But you might need to 0:16:35.760 --> 0:16:38.480 crank it back down again. Yeah, And and like I said, 0:16:38.520 --> 0:16:42.720 not all multiplayers are You can't mess with all multipliers. 0:16:42.800 --> 0:16:44.960 It all depends on the processors. Some of the processors 0:16:45.000 --> 0:16:47.760 are locked, so you let you can't do that, in 0:16:47.800 --> 0:16:50.440 which case you your only recourse is to change the 0:16:50.480 --> 0:16:52.640 setting of the motherboard as opposed to the setting on 0:16:52.760 --> 0:16:56.840 the processor. And also some motherboards you cannot do this 0:16:56.960 --> 0:17:00.720 through a software approach. You actually have to use physical approach. 0:17:00.720 --> 0:17:03.200 You have to change these components that are called jumpers, 0:17:03.720 --> 0:17:08.320 which that will uh will limit the motherboard speed. You 0:17:08.320 --> 0:17:10.960 have to you would have to physically replace those, which 0:17:11.000 --> 0:17:14.480 requires opening up your computer case and taking stuff out 0:17:14.520 --> 0:17:17.080 and changing stuff out, and that that can get a 0:17:17.119 --> 0:17:20.560 little intimidating for folks. It's a little bit simpler when 0:17:20.600 --> 0:17:22.920 you just hit a couple of buttons and then change 0:17:22.960 --> 0:17:27.840 some numbers on the screen, but that might be necessary 0:17:27.840 --> 0:17:30.119 depending on the motherboard. A lot of the stuff about 0:17:30.200 --> 0:17:33.960 personal computers depends heavily on the specific hardware you have, 0:17:34.880 --> 0:17:38.160 which is why if you ever think about building a machine, 0:17:38.680 --> 0:17:41.120 you should really do some research and make sure that 0:17:41.200 --> 0:17:44.320 you know what components you're getting before you you jump 0:17:44.400 --> 0:17:48.639 into it, because not every processor is compatible with every motherboard. 0:17:49.000 --> 0:17:50.760 So if you were to just try and create your 0:17:50.800 --> 0:17:53.280 own computer, build your own computer and you just you know, 0:17:53.359 --> 0:17:56.280 you were buying whatever was on sale. You might discover that, 0:17:56.359 --> 0:18:00.399 oh I got this great motherboard and this great sensor, 0:18:00.520 --> 0:18:03.119 but they aren't compatible with each other, so I can't 0:18:03.160 --> 0:18:05.800 actually build a machine out of it. Well, same sort 0:18:05.840 --> 0:18:08.520 of thing with overclocking. You just you know, they're different 0:18:08.560 --> 0:18:13.520 limitations based upon the actual hardware you have. And of course, 0:18:13.640 --> 0:18:17.439 uh it might involve, uh, depending on what you're doing, 0:18:17.640 --> 0:18:20.200 you might have to play around with the amount of 0:18:20.280 --> 0:18:26.159 voltage uh necessary to run. Yeah, well, I hopefully there 0:18:26.200 --> 0:18:29.679 are our listeners when we start talking about the amount 0:18:29.680 --> 0:18:33.960 of electricity we're getting into um or any any measure 0:18:34.000 --> 0:18:36.280 of electricity, they start going, oh, maybe I don't want 0:18:36.320 --> 0:18:39.360 to do this without you know, really doing some research. UM. 0:18:39.400 --> 0:18:42.000 I would very much recommend doing that if you are 0:18:42.040 --> 0:18:46.240 going to do getting into really messing with this UM. 0:18:46.280 --> 0:18:49.520 But yeah, they're it is worth noting though that uh 0:18:49.320 --> 0:18:54.200 uh certain boards are you know, certain processors, I should say, 0:18:54.480 --> 0:18:59.720 come with the the ability to overclock sort of sanctioned 0:19:00.080 --> 0:19:03.080 they're built in. Intel has several chips that you can 0:19:03.840 --> 0:19:07.440 uh go into a specific screen and change the settings 0:19:07.640 --> 0:19:12.320 if you want to overclock your processor. Extreme Edition Yeah. 0:19:12.400 --> 0:19:14.080 So that way, you know, you can do like the 0:19:14.119 --> 0:19:18.040 turbo stuff, or you can actually knock up the processor speed. 0:19:18.400 --> 0:19:20.880 You can change the multiplier a little bit, that kind 0:19:20.920 --> 0:19:23.639 of stuff. And uh you know again this is you 0:19:23.720 --> 0:19:25.880 might ask, well, why isn't it like that just out 0:19:25.920 --> 0:19:27.800 of the box. Well, for one thing, not everyone needs 0:19:27.800 --> 0:19:31.359 that kind of performance. And for another, uh, here's the 0:19:31.359 --> 0:19:34.000 thing about processors. We've talked about heat a bit and 0:19:34.040 --> 0:19:36.199 about generating heat, and too much heat can be a 0:19:36.200 --> 0:19:40.920 bad thing. When you have electricity running through a circuit, 0:19:41.359 --> 0:19:44.439 it generates heat as a byproduct. Yes, some energy is 0:19:44.480 --> 0:19:46.600 lost due to heat. Yeah, waste. It wastes some of 0:19:46.640 --> 0:19:51.640 its energy as heat. Yeah. So the more electricity you're 0:19:51.640 --> 0:19:55.760 pushing through the more the more uh work you're making 0:19:55.800 --> 0:19:58.440 your system do, the more heat it's going to generate. 0:19:58.920 --> 0:20:01.879 And before along, that heat might get to a point 0:20:01.920 --> 0:20:06.400 that's causing damage or or causing malfunctions within the machine itself. 0:20:06.680 --> 0:20:08.760 So you have to figure out a way of dispersing 0:20:08.800 --> 0:20:12.280 that heat um to handle that, or else your device 0:20:12.320 --> 0:20:14.040 isn't gonna work for very long. You might have the 0:20:14.080 --> 0:20:17.119 world's fastest computer, but only for a few minutes before 0:20:17.119 --> 0:20:22.160 it just uh yeah, well, of course, there have been 0:20:22.240 --> 0:20:25.399 computers with no fans, there have been computers with multiple fans. 0:20:25.400 --> 0:20:27.639 It all sort of depends on on the guts on 0:20:27.760 --> 0:20:30.720 the you know, the stuff that's inside the box um. 0:20:30.840 --> 0:20:34.639 And if you go to different overclocking communities you can 0:20:34.760 --> 0:20:39.600 learn about the parts and bits that people uh seem 0:20:39.640 --> 0:20:41.200 to feel are the best. Now, I saw a couple 0:20:41.200 --> 0:20:44.640 of fans listed as being excellent for overclockers because they're 0:20:44.640 --> 0:20:47.720 reliable and they push a lot of air um. But 0:20:47.920 --> 0:20:50.120 depending on what you're doing, that may not be enough. 0:20:50.320 --> 0:20:52.720 You might have to go to, say a water cooling system, 0:20:52.800 --> 0:20:56.400 which you know, water is a much more efficient dispersal 0:20:56.720 --> 0:21:00.800 of heat than than air is dispersal. I'm making up 0:21:00.800 --> 0:21:04.320 words now or misusing them at any rate. So anyway, 0:21:04.480 --> 0:21:07.240 water is much better at taking care of heat than 0:21:07.359 --> 0:21:10.560 than air is, and so a water based cooling system 0:21:10.720 --> 0:21:14.080 can be very useful for people who are overclocking their 0:21:14.160 --> 0:21:16.520 their machines and they want to really push it to 0:21:16.560 --> 0:21:20.280 the limit. Yeah, I was joking about the liquid nitrogen earlier, 0:21:20.320 --> 0:21:22.600 but there are people who have some very elaborate liquid 0:21:22.720 --> 0:21:27.040 cooled computer systems, and depending on how much you're you're pushing, 0:21:27.119 --> 0:21:29.439 especially if you have something like the again, like the 0:21:29.480 --> 0:21:32.280 Intel chips are the A M. D. S Black Edition 0:21:32.320 --> 0:21:35.040 chips where you can you've got the opportunity to really 0:21:35.080 --> 0:21:38.520 tinker with it, um you might do that. They are 0:21:38.560 --> 0:21:43.399 actually an overclocking competitions. Liquid nitrogen has been used to 0:21:43.480 --> 0:21:48.080 cool uh CPUs. Yeah, I'm just it's not the kind 0:21:48.080 --> 0:21:50.960 of thing that the general public because he's not gonna have. 0:21:51.160 --> 0:21:53.240 You'm not going to have a steady supply of liquid 0:21:53.359 --> 0:21:56.399 nitrogen to run through your machine constantly so that you 0:21:56.440 --> 0:21:59.359 can you can keep it going. But any how have 0:21:59.440 --> 0:22:03.760 you seen my nitrogen? It's not the stage. Why do 0:22:03.880 --> 0:22:08.280 you need to know the uh uh? Where is my 0:22:08.400 --> 0:22:11.359 super suit? The uh? Yeah? But if you if you, 0:22:12.240 --> 0:22:14.720 if you don't have a station have liquid nitrogen, then 0:22:14.760 --> 0:22:16.800 you know what are cooling or some other method is 0:22:16.800 --> 0:22:21.040 probably the best for you. But during these competitions that 0:22:21.200 --> 0:22:25.760 the purpose of the competitions isn't to build the fastest computer. 0:22:25.880 --> 0:22:28.480 It's to to try and push the limits of overclocking 0:22:28.480 --> 0:22:30.760 as far as you can go. It's not that you're 0:22:30.800 --> 0:22:34.640 going to have a practical machine after you're done, right, 0:22:34.680 --> 0:22:37.879 It's just this is an example of a a an 0:22:38.000 --> 0:22:41.760
