Introduction to CPU Overclocking - Core i7 5820K

2015-03-28
the aqua change of 240 from lepre is designed to complement your cpu overclocks with superior thermal dissipation and performance dual convex blades on the 120 millimeter fans deliver high volume airflow at low noise and the producer of copper plate deploys more coolant for efficient CPU hotspot elimination click the link in the description to find out more how's it going guys Kyle here with awesomesauce Network welcome back to the channel today I'm going to be doing a little bit of overclocking nothing too serious and I wouldn't consider this in tutorial by any means but this is more of like just a casual walk through I guess of my overclocking process that I do personally now everyone over clocks differently and the way overclocked is also going to depend slightly on what kind of desktop or what kind of system you're running as well so I'm clocking right now on my my personal desktop at home this is the one I edit on and this is the one that I do all of my encoding for for all the YouTube videos that you see on the channel so first off I'm in the UEFI right here of the gigabyte the gigabyte UEFI dual BIOS now this is an X 99 board I'm overclocking a 5820 5820k but regardless of which has well II CPU you might be overclocking they all function more or less the same so you can apply whatever I'm doing here to your own haswell-e CPU if you have one so jumping right into it the first thing we'll see if we go to the frequency settings is the CPU base clock now the base clock starts out at 100 megahertz by default but you can kind of adjust certain parameters to to get you a higher clock speed so for example if we go to our CPU clock ratio now you can whatever you enter here will be multiplied by that hundred megahertz frequency and that will give you your your final CPU frequency so the just below that you can see 3.3 gigahertz right here now I'm going to just start tuning things now you can either do this you can do this a couple ways you can either do it in increments so you could go you know let's say you wanted to overclock it to 3.5 wait but that's not 3.5 up my num lock my num lock goes on sorry about that change this alright so you can do three five and if you enter that now you'll see that our new C you frequency is 3.5 gigahertz or 3500 megahertz so you can do it incrementally and just keep going up and doing stability tests every time you you go up a notch so you can do a stability test here and if that passes then you can go on to the next one and you keep going until your system crashes at that point you could either leave it as is or you could try increasing the voltage now voltage basically just drives more power to the CPU allowing you to hit those higher clock speeds however it also generates more heat in your system and can also decrease the lifespan of your CPU over time especially if you're doing some really aggressive over volting so the other method of overclocking is to just kind of go go for a more aggressive overclock from the get-go so I'm going to go with 44 we're going to do 40 400 megahertz right here and then I'm going to back out into the voltage obviously I've done this before so I'm kind of familiar with what the system is capable of and what the CPU can handle so under my core voltage I'm going to change this you can see it's stock at 0.975 I'm going to do 1.3 now the reason I'm doing 1.3 is for several reasons the first of which is because JJ from ASA said so he actually did say this in the PC DIY video that he did during the launch of haswell-e he basically said 1.3 volts is the most you should go for for certain types of systems and my system applies to that that field of criteria because I'm doing a lot of encoding and rendering I'm actually stressed stressing my CPU continuously for very long periods of time so at that rate 1.3 volts should be the max that you go now if you aren't using your system for editing and you're just doing more day-to-day tasks or even some heavy gaming you could easily over volt this quite a bit further to like 1.4 for example without too much trouble but because I am going to be encoding a lot on this system I'm going to keep it at 1.3 I'm not going to go higher than that so let's hopefully hopefully this will work out I'm going to save changes and exit and I'm just gonna let the system boot up and by the time we get into Windows I should be running at 4.4 gigahertz and whether or not the system can handle it will depend on if it can pass the stability test that I throw at it the stability test that I'm going to be using today is a cease real bench the reason why I'm using real bench is because it actually does a lot of real-world applications when testing unlike print something like prime95 where it's literally just maxing out all the cores at the same time it doesn't really reflect a representative workload for what you might experience on a day-to-day event all right so I've opened up the program I'm going to go over to stress test and let's just do a 15-minute run I have 16 gigs loaded into this system so I'm going to select that and just give it a second to gather the system information so that it can run the appropriate tests and once that's done you can just go ahead and start and it'll do its thing again these are all real world type workloads that it's putting on my CPU CPU is at a hundred percent usage right now you can see that we're hitting the 4.4 gigahertz overclock that we set with that multiplier of 44 and it's super tiny text but there it is still with the default bus speed of a hundred megahertz now so far so good doesn't look like we're crashing crashing or anything on but I'm going to let this run the whole 15 minutes to see and make sure that we're stable before we try pushing the CPU even further all right we're back into the UEFI now because we actually did pass our stress test in rail bench so I'm going to go back to the frequency settings and crank this up to 45 so we're going to go for 4.5 gigahertz here at again at 1.3 volts and I'm going to see if we can run the same stress test and still be stable all right so I'm a little sad that we couldn't hit 4.5 at 1.3 volts but I guess it's not a huge deal this just means that I'm probably within the I don't know 70 to 80 percentile of haswell-e CPUs that shipped out from Intel I think Paul was able to hit four point six or four point seven at one point three don't quote me on that but I'm pretty sure he got a really well bin CPU so good for him Paul you suck for hogging up all the good CPUs so I'm gonna have to go back down to 44 damn NumLock so I'm going to go back to 44 and then I'm going to go back into the frequency I'm sorry the voltage settings my CPU core voltage now I'm going to see if I can get away with a lower voltage because that'll save me a little bit of power so instead of one point three let's go one point two nine five I'm gonna run the same stress test so you can see for those of you not too familiar with overclocking it is a very tedious and time-consuming task if you want to do it all manually yourself but obviously that's that's one of the fun things about it is being able to tweak and tune your system and doing a lot of trial and error seeing what works and what doesn't but when you find that perfect stable overclock it's a really good feeling so let's jump back in here and see what we can do alright so we're about three minutes into real bench right now and so far we're looking good temperatures right now in our hottest core is 88 degrees Celsius and I'm not going to let that bother me again I'm not too concerned about what the temps are in real Bench I'm more concerned about what I'm going to be seeing when I'm doing some real-world applications while this is a real-world stress test it's it's not exactly I'm not going to be running real bench every time I boot my computer up I'm going to be rendering videos using Photoshop editing videos and stuff like that now that being said you should still have an adequate cooling solution if you're going to be putting an aggressive overclock on your system and on your CPU and speaking of which I've got a Corsair H one hundred-eyed GTX currently cooling the 5820k in my system it's a 240 millimeter liquid cooler it's doing a great job so far and that's also allowed me to push the envelope and limitations of the CPU a bit further than if I were using an air cooler for example or even a liquid cooler with a smaller radiator alright so we just finished up our 15 minute stress test in Rio bench and we passed no crashing nothing like that so I think we're to go I did want to point out that you guys may have noticed that the speed here was reading 30 300 megahertz the whole time during the test but midway through the test I pulled up cpu-z and we were in fact running at 4400 megahertz so I just want to get a give you guys some reassurance there must just be a glitch with real Bench aside from that our max temp was 94 degrees Celsius on the hottest core which honestly looks pretty alarming but if there was something horribly wrong the CPU would have just shut down to prevent any kind of damage from happening to the CPU so at this point you could go back into your UEFI and if your particular BIOS allows it you can do things like change your voltage setting to adaptive voltage because right now we are at just a fixed voltage so whether we're under load or whether I'm at a low power State idling I'm still going to be at one point two nine five volts and that can honestly wear and do some wear and tear on your CPU over time so switching it to something like the adaptive voltage can really help you save some energy and some power and longevity in your CPU as well and in closing I just want to quickly share some performance numbers with you guys because when it comes to overclocking your Hardware seeing how much extra performance you can squeeze out of it is what it's really all about so I've already done to render tests in Adobe Premiere Pro cs6 they were five-minute clips or it was a five-minute clip at 1080p h.264 and it had a bunch of color correction filters on it just to make the test a little bit more taxing and at the clock at the stock clock frequency of 3.4 gigahertz I was able to render the clip in about 6 minutes and 34 seconds which isn't too bad I mean this is still has well ISO even its dock clock frequencies you're getting pretty good render times but then after dialing in the overclock of 40 400 megahertz I was able to shave that down to just 5 minutes and 15 seconds at that point you're talking almost real-time encoding right I mean that was probably almost a minute of render time for every minute of footage so definitely able to shave down quite a bit there and when you're talking about longer projects like when I render an episode of awesome hardware which is sometimes over an hour long I mean in the long run you're saving yourself hours upon hours of encoding time which is a really nice to see also did want to point out that the hottest my CPU ever got during the overclocked render test was 78 degrees Celsius I believe it was on core number 4 that one tends to get a little bit hotter than the others but obviously you can see that's much lower than what we were hitting with the real bench stress test and again I think the best way to test to see how hot your hardware gets is to really just run the applications that you normally run day-to-day gives you the most accurate representation it's most indicative of what you're expected to see but that of course is just what works for me personally and I guess that's kind of why I wanted to share this experience with you and kind of just show you what I go through when I overclock my CPU at home but hopefully you guys enjoyed this video if you did toss me a like on it and feel free to subscribe to the channel for more tech videos coming at you really soon thanks for watching guys I'll see you in the next one
