Hey there, with a day off work today I jumped right into overclocking my rig.

Intel Core i7-6700K
NZXT Kraken X61
Asus ROG MAXIMUS VIII HERO ALPHA
Corsair Vengeance LPX 2x8GB DDR4-3000
Asus STRIX GTX1080 O8G

I was able to get my CPU @4.8GHz, 1.35V to being stable in AIDA64 stability test for about 20 minutes.

However, I am not sure how I feel about temperatures and so on. When running my CPU cooler on Silent mode, my temps got to about 82°C after 5 minutes of testing. I had to turn that test off because I was just afraid.

When I turned on Performance mode on my cooler, the PC got (obviously) very loud, but it kept the temperatures on about 60°C on average, with a maximum temperature of 75°C (and that was only on one of the cores) for the 20 minutes.

In both cases, the AIDA64 CPUID showed the Core Voltage at 1.394V max (jumping back and forward).

The liquid temperature has reached about 33°C after that 20 minute test.

My question then is, is this a good OC? I plan to play with the cooler settings a bit so I expect the stability test to get to 80°C max... Also, how does the stability test differ from actual gaming? Am I gonna encounter higher temps during games or vice versa?

Sorry for those silly questions, I have never tried to overclock anything this much, so any idea/help is highly appreciated. Thanks for answers.

the stress test should get hotter than actual gaming

personally i am not a fan of stress testing to the extreme i just stress my cpu by doing everything i normally do at the same time

i dont like mine over 70c even though thats not too high for it any way its just the target i aim for with the fans still being quiet

though i am on full watercooling not an aio so obviously going to be cooler

1. when you do the stability test, you should set the voltage to manual mode (no dynamic). it will leave the voltage at 1.35v and the temperature will be lower. when you are done with stability testing, you can switch to "dynamic".
2. the gaming load temperatures are lower then those of stability tests.
3. you want your CPU up to 75C (short spikes are not important) under load for every day uses like gaming.
4. with liquid cooling, you want to run the test at least about a hour. it takes some time for the loop temperature to stabilize and than you want 20-30 mins at least of continuous load at max temp. for your sake, i hope you got a cooler with at least 240mm radiator.

I have the NZXT Kraken X61, which is 280mm if I am not mistaken, I think my temp is ok with the Performance mode enabled on my cooler, but in Silent mode it gets to 80°C, so I need to find a middle bridge. I will do the test for an hour then when I get home and I will try some gaming after that while watching the temps carefully. Thank you for your help :)

In addition to the help being offered here I just want to chime in with a question. Why are you overclocking? Yes. Why do people climb mountains..... What return is the OC offering you other than increased heat? It's good to get to know your rig, your OS and the ins and outs of overclocking. After that I would look to the return for my overclocking. What's it giving you? You have an EXTREMELY capable rig. The 6700K with a 1080 with 16GB RAM is a power team that can handle 4K gaming on a 144Hz monitor or TV. I can overclock my much less powerful rig but at the moment it's more than capable. I get from 60 to over 100(or more) in all of my games. On a 1080p 60Hz monitor I don't need 144FPS+. More would simply be more that could then lead to screen tearing and all that...

the overclocking applies to everything you do on the pc not just gaming

why would people buy a 4ghz cpu over a 3ghz cpu? assuming identical cpu other than the ghz


because its faster

Understood. My question did not only apply to gaming. Just saying he has some high end parts.

yes he has but as long as you have adequate cooling the extra bit of speed is free,,every one loves something for nothing lol

Yes, it is. I can be in control of a high end car. The speed limit is 80MPH. My point is is that this system well exceeds system requirements for MANY programs. An overclock would only exceed those requirements even more. My reasoning is this. My system already completes a 1080p editing job in 34 seconds. I experience 169FPS in a particular game. I have completed many other jobs as well. Okay, My hardware can be overclocked. Let's do it. WHAT????? My overclock did nothing for my editing or rendering job.a When I was gaming I still received 169FPs. There is still going to be a time with my Bugatti Chevron(which I don't own) that my top speed will be met and tuning my already heavily modified engine results in 0 mph increases. There is a point that an OC will not be met with real world benefits. He or she is only using a 5400RPM HDD. They then use a M.2 SSD. The overclock did nothing. The SSDD did. Okay, et's include your reasoning. They are getrting 180FPS in BF1 on ultra. What does 200FPS do for them? They get 20FPS more for free. Their score is also a record(not likely with the pascal Titan X) for a Heaven benchmark. There benchmark is better than they have ever received. So good. In their real world applications the OC nets them no time decrease in editing jobs that with a 1070 and 6600 OC's to 5.0 takes 24 seconds longer and with their system still takes them 20 seconds regardless of an OC. There will be a time where an OC will not be better or faster.
