core i7 6700k first OC

[gghilliard]

Hi,

I am currently in the process of my first overclock. Here are my specs.

intel core i7 6700k
asus Z170-A
16GB DDR4 G Skill Ripjaw V 3200MHz
Asus ROG swift GTX 1080
Windows !0 64bit

I was aiming to get 4.6GHz. I thought it was stable at 1.390v. After 9hr40min it crashed with a max temp of 88. I am now stress testing 4.5GHz at 1.375v. I'll see what that does. My real question is about temps.

I am using aida64 for the stress test. I am also using the asus ai suite software and CPUID HWMonitor to watch the temps. HWMonitor is 10 deg higher than asus and aida64. Does anyone know why that would be? During most of the 9hr test my temp was hovering right around 65C. Which from what I have read is good. But then the crash.

Also, should I be concerned with the individual core temps? or only the overall cpu temp? Which software will give me an accurate temp reading?

Any input would be greatly appreciated. Thanks in advance Tom's community.

I'm no expert in overclocking but I'm pretty sure 1.390v is CRAZY HIGH voltage. You want to get that as low as possible while still being stable. I for example have my 4790k running at 4.6 with 1.205v and I'm still working on it, Going to try even less with my next test.

Intel says I should exceed 1.45v. I was trying to stay below 1.4. Stock voltage was around 1.320. Also. I should add I have a corsair H100i v2 closed loop liquid CPU cooler.

Correction. Shouldn't exceed 1.45v.

hello, if u did all correctly then sorry u lost your silicone lottery.
I have the same cpu overclocked to 4.7GHZ at 1.320v. My cooler is 212 evo and i get max 85C in Intel burn test or under 70C during AIDA64 stress test.
1.390 is NOT crazy high 😀 but its quite high. Its really depends on person and luck but my sweet point is under 1.350v for 24/7.
Im pretty sure Intel® Extreme Tuning Utility (Intel® XTU) shows more accurate temperatures, you can download it to measure those temps. Or just use HWmonitor it shows pretty correct too.
Well some tips for you which worked best for me:
I would rather use bios for overclocking but AI suite will do the job for basic overclocking.
So your overclock looks pretty bad so if i were you i would go to bios and restored all settings. Just press F5.
Once its clean check LLC level, i had 7 by default and i set it to 4 which decreased my temperatures at least 10C. Try to set level 5 and leave like that, you may increase it later if you overclock will be unstable. I always like to search on the internet on what other people could achieve. So in my case i changed multiplier to 45, put voltage to 1.250 and boot to windows for stress test, if it not stable go back to bios and increase voltage by 0.010 and do this step until u get it stable. I never run tests for 9 hours like u do, in this case i would run 5-10 min intel burn test to check quick stability and temperatures. So after i found voltage that can keep my 45 alive i go play games, those games that cpu demanding. I find it most enjoying stress test and most correct. If crash increase voltage by 0.010 more and so on. Make sure u dont overclock at the same time your gpu or ram or cache anything cuz if u get freeze black screen or blue screen u wont know what caused it. Im not a pro but this overclock i got looks decent for budget cooler and it runs stable for around 4 months with no single crash.
