WEBVTT 00:00:02.600 --> 00:00:21.470 there no place there no moment 00:00:30.759 --> 00:00:37.079 welcome to my Devil's Canyon and Pentium anniversary edition overclocking guide 00:00:35.480 --> 00:00:41.399 now the drawbacks of overclocking your CPU are many overclockable Hardware is 00:00:39.600 --> 00:00:46.520 more expensive if it's done incorrectly it can cause your computer to blue screen or otherwise be unstable it makes 00:00:44.440 --> 00:00:50.440 your PC consume more power and output more heat it can make your processor not 00:00:48.480 --> 00:00:56.160 last as long it avoids the warranty on many components and finally doing it 00:00:53.199 --> 00:01:01.920 right can be down right time consuming so why do we do it because we want to go 00:00:59.239 --> 00:01:01.920 fast 00:01:02.680 --> 00:01:09.200 H now before we get into this guide when it comes to running things beyond their 00:01:07.240 --> 00:01:13.600 specifications I don't think I have to spell out that nothing is guaranteed so 00:01:11.920 --> 00:01:18.360 with that out of the way let's get into the parts we're using for our guide 00:01:15.159 --> 00:01:21.400 today for the CPU we actually have two 00:01:18.360 --> 00:01:23.040 different choices the first is a 4790k 00:01:21.400 --> 00:01:27.240 which is a quad core with hyperthread and clock do a little faster than the 00:01:24.799 --> 00:01:32.640 older 4770k from our last overclocking guide at 4 GHz base and up to 4.4 4 GHz 00:01:30.520 --> 00:01:36.360 boost it features an upgraded thermal solution for cooler temperatures versus 00:01:34.360 --> 00:01:40.640 its older brother and due to refinements in Intel's chip selection process 00:01:38.119 --> 00:01:45.320 promises more consistent overclocking results a fine Choice oh and like its 00:01:43.079 --> 00:01:49.600 predecessor it's a ker skew which means it's unlocked and overclocking ready 00:01:47.520 --> 00:01:54.200 which leads us into our second CPU the Pentium 00:01:50.840 --> 00:01:56.439 g3258 anniversary edition this chip is 00:01:54.200 --> 00:02:00.079 truly remarkable it's not the fanciest thing in the world with no 00:01:57.439 --> 00:02:06.880 hyperthreading only two processing cores and a mere 3.2 GHz stock clock speed but 00:02:03.439 --> 00:02:09.239 it's unlocked which means maybe a 00:02:06.880 --> 00:02:13.400 massive overclocking potential for cooling we're using a Corsair h100 00:02:11.760 --> 00:02:16.879 liquid cooler I recommend a good Tower air cooler or a dual fan all-in-one 00:02:15.400 --> 00:02:21.200 liquid cooler for the best overclocking results for our power supply we've gone 00:02:18.680 --> 00:02:26.760 with the Corsair ax850 we could have gone Overkill with the latest ax1 1500i 00:02:24.360 --> 00:02:30.840 but getting a gr overclock is not about having a high wattage power supply as 00:02:29.080 --> 00:02:34.319 much as it's about having a good quality one with stable rails and very little 00:02:32.360 --> 00:02:38.000 Ripple so this one will be okay the ax500 I would have been better but this 00:02:36.000 --> 00:02:42.480 one will be fine speaking of Overkill we've gone slightly overkill on the 00:02:39.800 --> 00:02:47.000 motherboard with a z97 WS from ASUS both Luke and I are very fond of WS series 00:02:45.040 --> 00:02:49.640 boards they're just so dependable and easy to work with they offer great 00:02:48.319 --> 00:02:56.200 compatibility with other components amazing build quality and while they lack some of the fancy extras that Ro or 00:02:54.360 --> 00:02:59.519 tough series boards might have they've got it where it counts and they'll 00:02:57.560 --> 00:03:03.120 overclock with the best of them these days the motherboard actually doesn't 00:03:01.040 --> 00:03:07.080 affect overclocking results much unless you're pushing things to the limits with 00:03:04.799 --> 00:03:10.640 exotic cooling anyway so as long as you pick an Aus motherboard you should be 00:03:08.920 --> 00:03:14.680 able to follow along with our guide exactly with other brand motherboards 00:03:13.040 --> 00:03:17.400 having similar options with just a little bit more digging required on your 00:03:16.080 --> 00:03:23.879 part to match up the stuff we're changing to how what it looks like on the other board finally for memory we're 00:03:20.959 --> 00:03:27.760 using an 8 gig kit of 2400 MHz gskill memory high-speed memory isn't a huge 00:03:25.840 --> 00:03:32.920 deal these days but with how much less expensive it's gotten lately compared to 00:03:29.799 --> 00:03:34.640 standard 1600 MHz stuff and how easy it 00:03:32.920 --> 00:03:39.120 is to dial in at high frequencies with XMP profiles we figured what the hate 00:03:37.239 --> 00:03:42.680 it's optional but we'll show it to you anyway okay lonus enough Preamble how do 00:03:41.840 --> 00:03:48.439 I overclock step one don't overclock start 00:03:46.640 --> 00:03:52.200 by updating your BIOS and drivers running a stress test for an hour or two 00:03:50.480 --> 00:03:55.840 doing at least a couple passes of mest 86 and playing games for a couple of 00:03:54.400 --> 00:04:00.280 hours to ensure that things are functioning correctly out of the box 00:03:58.439 --> 00:04:03.920 after all you wouldn't take a new car to the track and Tred to go 200 km an hour 00:04:02.640 --> 00:04:09.040 in it until you made sure it can stay in a straight line going 60 clicks right 00:04:06.280 --> 00:04:12.640 step two gather your software toolkit while I mentioned mest 86 already you're 00:04:10.959 --> 00:04:17.680 going to want a couple of other things in your bag of tricks for stress testing 00:04:15.200 --> 00:04:21.720 CPUs Z lets you see how your processor is running so you can verify your 00:04:19.160 --> 00:04:25.919 settings and Cort temp lets you monitor your CPU's temperatures in real time to 00:04:24.160 --> 00:04:30.320 see if they're getting out of hand if you want an all-in-one utility and a 00:04:27.880 --> 00:04:34.960 nice userfriendly package I to 6 4 gets a solid recommendation from us it's what 00:04:32.680 --> 00:04:40.639 we use and it includes monitoring stress testing and diagnostic stuff but it does 00:04:38.240 --> 00:04:46.680 cost money everything else I mentioned is free step three set aside the time to 00:04:44.240 --> 00:04:51.199 do it properly be prepared to have your system not be usable for a day or two if 00:04:49.280 --> 00:04:55.560 you want to correctly dial in an overclock I'm not saying it will take 00:04:53.320 --> 00:04:59.840 that long I'm just saying it can take that long especially if you're a real 00:04:57.479 --> 00:05:04.000 stickler about validation I've seen stress testing programs fail after even 00:05:01.720 --> 00:05:08.320 a full day of Burnin and my personal standard is that if it's not 100% stable 00:05:06.720 --> 00:05:13.320 I'd rather turn it down a little rather than risk losing valuable work and data 00:05:10.479 --> 00:05:19.199 so I typically validate for 24 hours or more step four the tour of the UEFI BIOS 00:05:17.360 --> 00:05:23.160 on most motherboards pressing delete will land you in the ufi BIOS if you're 00:05:21.560 --> 00:05:27.600 not sure about your motherboard consult the menual a Seuss drops you into a 00:05:25.199 --> 00:05:30.600 simplified ufi by default that gives you all the basic info you need like 00:05:28.880 --> 00:05:34.840 temperatures and lets you adjust your fan speeds change boot order and enable 00:05:32.280 --> 00:05:39.680 your memories XMP profiles but doesn't really allow for any serious tuning 00:05:36.360 --> 00:05:41.600 press F7 to get to advanced mode most 00:05:39.680 --> 00:05:45.160 modern motherboard bioses have a ton of features that we didn't have in the old 00:05:43.440 --> 00:05:48.440 days you can navigate through the menus manually or you can create your own 00:05:47.000 --> 00:05:51.639 favorites menu with the settings that you use most frequently you can make 00:05:50.120 --> 00:05:55.840 quick notes as you progress through your overclock and review them later you can 00:05:53.880 --> 00:05:59.319 save profiles for known good settings so it's easy to revert to something that 00:05:57.199 --> 00:06:03.800 works when you're done experimenting and you can even have the motherboard take 00:06:01.199 --> 00:06:06.440 care of overclocking for you on its own we're going to experiment with that 00:06:04.840 --> 00:06:10.280 feature later on to see how close it can get to the performance of our manual 00:06:07.880 --> 00:06:15.240 overclock now if you want a bit of a deeper rundown of every setting things 00:06:12.919 --> 00:06:19.479 actually haven't changed a lot since our last Haswell overclocking guide in this 00:06:17.840 --> 00:06:24.759 guide we're going to leave most of the dials on auto and explain only the ones 00:06:21.800 --> 00:06:28.720 that we're changing as we go let's jump into the AI tweaker heading where most 00:06:26.639 --> 00:06:32.440 of this stuff is found now most Enthusiast grade memory these days has 00:06:30.280 --> 00:06:37.720 an XMP profile and if you set this setting to XMP it will dial in into its 00:06:35.400 --> 00:06:41.840 optimal settings you can push memory past its rated speeds but because of how 00:06:40.240 --> 00:06:47.000 difficult memory instability is to diagnose I really don't recommend doing 00:06:44.599 --> 00:06:52.039 it unless you have a lot of patience moving on down the CPU core ratio is 00:06:49.840 --> 00:06:57.039 where most of the magic happens this ratio times the base clock locked at 100 00:06:54.880 --> 00:07:00.120 MHz for all intents and purposes is how the processor's final frequency is 00:06:59.080 --> 00:07:04.479 derived as for the settings here sync all cores 00:07:02.400 --> 00:07:08.840 is faster and easier to dial in because it runs every core at the same speed 00:07:06.319 --> 00:07:13.560 which is easy to stress test but setting up different maximum turbos depending on 00:07:11.199 --> 00:07:17.440 how many cores are active could yield slightly better results in dual or 00:07:15.720 --> 00:07:22.879 single threaded applications we're going to stick with sync all cores next up is 00:07:20.160 --> 00:07:27.759 the CPU core voltage increasing core voltage improve CPU stability at higher 00:07:25.319 --> 00:07:32.599 clock speeds but higher voltages are also the main reason that overclocking 00:07:30.039 --> 00:07:36.759 causes higher temperatures and a shorter lifespan for your processor now there 00:07:34.840 --> 00:07:41.160 are actually several ways to set CPU voltage we're going to use manual 00:07:38.879 --> 00:07:46.039 voltage the generally regarded as pretty safe voltage being 1.3 Volts for Haswell 00:07:43.080 --> 00:07:51.360 based CPUs to find our Max over clock then to save power we're going to switch 00:07:48.360 --> 00:07:53.080 to Adaptive later on adaptive gives us 00:07:51.360 --> 00:07:57.039 better power consumption characteristics when the computer is not working hard 00:07:55.039 --> 00:08:00.879 and ramps up whenever the CPU needs more juice but it's not good for stress test 00:07:59.680 --> 00:08:05.240 when you're actually validating the overclock because certain stability 00:08:03.319 --> 00:08:10.159 testing applications can cause voltage spikes that can hurt your CPU in 00:08:07.479 --> 00:08:13.400 adaptive mode so now that we're familiar with the settings that we'll be running 00:08:11.599 --> 00:08:17.800 it's time to overclock we're going to start by leaving our CPU at stock 00:08:15.080 --> 00:08:21.360 voltage so 1.25 volts this is different from Auto which will actually scale 00:08:19.759 --> 00:08:24.840 voltage as you increase your frequencies thanks to the same BIOS Wizardry that 00:08:23.560 --> 00:08:30.560 will automatically be handling all the other settings in here that we didn't cover then we're going to turn all of 00:08:28.199 --> 00:08:35.240 our cores multiplier up a little bit let's say to 44 which would give us a 00:08:32.399 --> 00:08:38.680 speed of 4.4 GHz actually equal to what turbo boost will do on its own but let's 00:08:36.800 --> 00:08:42.080 just see if it can do it all the time so now we press F10 to save our settings 00:08:40.240 --> 00:08:46.839 boot into Windows and do some stability testing if the CPU passes a short let's 00:08:44.839 --> 00:08:49.920 say 5 to 10 minute stress test and temperatures are within your comfort 00:08:48.360 --> 00:08:54.279 zone remember higher tempts equals shorter CPU lifespan then we boot back 00:08:51.959 --> 00:08:58.320 into the BIOS and push it some more if it fails then we add a bit more voltage 00:08:56.279 --> 00:09:02.519 and see if that makes it stable it's important to go through this process to 00:09:00.519 --> 00:09:07.160 find out where you're needing to crank up the voltage a lot for a very small 00:09:04.800 --> 00:09:11.200 CPU frequency return that's the way to find the balance between the longevity 00:09:09.079 --> 00:09:15.000 of your chip and the extra performance that you crave another thing to consider 00:09:13.600 --> 00:09:19.440 is the conditions in which you're overclocking is it optimal is it the 00:09:17.279 --> 00:09:23.399 worst case scenario an overclock that you set up in the winter might not work 00:09:21.519 --> 00:09:27.519 correctly in the summer so leave yourself some buffer room or save a 00:09:25.560 --> 00:09:31.160 couple of other profiles that work in case you need to grab one of them when 00:09:29.000 --> 00:09:35.440 the weather heats up another thing to consider if you're working on other more 00:09:33.640 --> 00:09:39.279 advanced settings within the BIOS let's say you want to do some tuning to the 00:09:36.800 --> 00:09:43.560 RAM timings is to throw another step into the routine not everything you 00:09:41.240 --> 00:09:47.240 tweak will have a positive result so run a short Benchmark rather than just a 00:09:45.440 --> 00:09:51.760 stability test to see if what you're doing is actually helping or hindering 00:09:49.880 --> 00:09:56.279 performance once you've dialed in your overclock using manual voltage switch 00:09:54.040 --> 00:10:00.560 over to Adaptive then use a real world stress test like cinebench to validate 00:09:58.480 --> 00:10:04.800 your load voltage I found that just doing the math and keying in the same 00:10:02.279 --> 00:10:08.160 number actually didn't work so I used AI Suite to make sure the voltages were 00:10:06.320 --> 00:10:12.399 right and even though the software voltage readouts are typically not very 00:10:10.000 --> 00:10:16.279 accurate the system was stable and my load temps were similar once I turned 00:10:14.399 --> 00:10:20.200 things up a little bit more so it seemed to work a digital multimeter would 00:10:18.240 --> 00:10:23.399 actually be preferable if your board has voltage checkpoints though that's a 00:10:21.880 --> 00:10:29.320 great feature for overclockers unfortunately not found on WS 00:10:25.880 --> 00:10:32.040 boards so following this methodology we 00:10:29.320 --> 00:10:38.200 we achieved a 4.8 GHz on our 4790k at 1.3 Vols with a load CPU temperature of 00:10:34.440 --> 00:10:43.079 around 65° and Rock Solid stability and 00:10:38.200 --> 00:10:46.560 4.7 GHz on our g3258 at 1365 volts with 00:10:43.079 --> 00:10:49.920 a load CPU temperature of 49 Dees I gave 00:10:46.560 --> 00:10:52.040 the Pentium about 065 volts more than 00:10:49.920 --> 00:10:56.320 the typical best practice setting for Haswell for a couple of reasons number 00:10:54.240 --> 00:11:01.600 one is that temperatures were still great since it's a dual core and doesn't 00:10:58.639 --> 00:11:06.560 output much and number two is that as a $75 chip I'm a little bit more willing 00:11:04.079 --> 00:11:10.000 to live on the wild side with it both of these results are going to turn into 00:11:07.959 --> 00:11:13.680 some significant real world performance improvements but by now you might be 00:11:12.040 --> 00:11:17.560 sitting there kind of going well lonus this is all fine and good but ain't 00:11:15.480 --> 00:11:22.680 nobody got time for that is there another way well actually there are two 00:11:20.440 --> 00:11:27.160 other ways that I alluded to before to overclock on an isus motherboard number 00:11:24.639 --> 00:11:31.040 one is to Simply navigate to the easy tuning wizard in the BIOS answer a short 00:11:29.720 --> 00:11:35.079 questions about your setup then let the board apply one of the pre-done profiles 00:11:32.800 --> 00:11:39.160 that asusa Engineers have cooked up this resulted in lower more conservative 00:11:37.279 --> 00:11:43.480 overclocks at higher temperatures for both of our chips temps were still 00:11:41.480 --> 00:11:49.560 reasonable at only a couple of more degrees on both CPUs but it's just plain 00:11:47.320 --> 00:11:55.320 not as good as a manual overclock the second alternative way is to use ausus 00:11:51.760 --> 00:11:57.200 AI Suite softwares five-way optimization 00:11:55.320 --> 00:12:02.000 feature to have the board overclock itself it actually goes through much the 00:11:59.920 --> 00:12:05.880 same increase speed until unstable then increase voltage until stable rinse and 00:12:03.560 --> 00:12:10.040 repeat process that we did except it does it completely on its own and it 00:12:07.880 --> 00:12:16.199 actually works reasonably well the automated system ended up 100 MHz slower 00:12:12.440 --> 00:12:19.160 on my 4790k and 100 MHz faster on my 00:12:16.199 --> 00:12:24.079 g3258 with the only issue being that in both cases it was applying More Voltage 00:12:21.880 --> 00:12:28.279 than I was really comfortable with and since I'd already tested the system and 00:12:26.079 --> 00:12:33.920 found it to be stable with less voltage it seems like as was overdoing it a bit 00:12:30.920 --> 00:12:35.519 in both cases not a huge deal if you 00:12:33.920 --> 00:12:38.800 just want a quick and dirty overclock since it can dial it in in about 10 00:12:37.160 --> 00:12:43.880 minutes and you don't even need to touch it and they were both stable it's just 00:12:40.800 --> 00:12:45.680 not the proper way to do things either 00:12:43.880 --> 00:12:48.959 and that pretty much wraps it up thanks for checking out this overclocking guide 00:12:47.279 --> 00:12:52.880 if this answered your questions then Happy overclocking if it didn't and you 00:12:50.920 --> 00:12:56.079 still want some
