Overclock 6600k on Asus Z170 pro gaming

[Daniel_Khazaei]

Hello to all

I have a question about ASUS automatic overclocking in the bios!
I have set the EZ System Tuning to ASUS optimal in the bios and X.M.P enabled.

system -->>

cpu: core i5 6600k
MB: ASUS Z170 pro gaming
RAM: G. Skill Ripjaws 2x8 GB 2400 MHz
GPU: Radeon HD 4670 (not for gaming of course)
cooler: deepcool iceedge mini fs v2 cpu cooler + 1x120mm intake + 1x120 exhaust
PSU: Green 600-hp Bronze (600w)

I usually use the system for numerical simulation on 4 cores and max fan speed!
When idle the cpu multiplier goes up to 43 corresponding to 4.3 GHz with the cpu core voltage changing between 0.784v to 1.114v. Also the package temperature is around 24-25 C!

The problem is under full load using the commercial software for my numerical simulation on 4 cores, the multiplier will be fixed at 41 with cpu core voltage around 1.245v! The maximum package temperature reaches to 63 C with an average around 53 C.

Why I don't get the fixed 4.3 GHz for my simulations? Is this a normal behavior when using automatic ASUS overclocking?

thanks in advance

Never use software to overclock!!!!!!!

what do you suggest? is there any guide for skylake?

Dont use any auto overclock feature. You dont want your voltage jumping around. One minute your voltage could be 1.2 and the next could be outside of the safe zone for operating. Use the UEFI Bios for overclocking and do it manually. Its really not that difficult. Set your multiplier to whatever speed your trying to achieve, for example enter 43 for 4.3ghz. Then change your core voltage to manual and enter a set voltage to supply to your CPU. 1.3 for example. Then. Save and reboot your computer and run some stress tests for minimum of 1 hour to test stability of your overclock, if it passes the test then your overclock is stable.

Change your power management options to performance in windows, this will remove the power saving mode and allow your processor to run at the overclocked speed 100% of the time.

I have read the information on that link about Skylake overclocking and tried the manual way:

I have set the multiplier to 44 (4.4 GHz) and CPU Core/Cache Voltage to 1.155v.
Now the clock remains at 4.4 GHz under full load, however the CPU Core/Cache Voltage still changes slightly. Also I see different voltage values in AI Suite, CPU-z and HWMonitor:

AI Suite

CPU-z

HWMonitor

Also I have read that I should start with 1.35v and check if the system can boot normally! However my cpu just boot normal with 1.155v set as CPU Core/Cache Voltage in the bios. Is something wrong?

Now I'm stress testing with Prim95 and the max reported temperature is 63 C with full fan speed!

In BIOS just raise the multiplier, and leave anything els on auto. or Google it
