6600k OC'd 4.2 Ghz - 79C Prime95
6600k OC'd 4.2 Ghz - 79C Prime95
Hey everyone.
This is my initial experience with overclocking. I just switched my motherboard from Asus H170 to Asrock Z270 and installed an i5 6600k processor. I'm also using a H60 cooler with a push and pull fan setup.
The configuration is:
Asrock Z270 K6 Gaming
6600k
GTX 1070
650 W gold+
16 GB RAM DDR4 2400
Currently, I'm running at 4.2ghz with the Asrock OC tool from the BIOS. The maximum temperature I've reached so far is 79°C, and my idle temps are around 30°C.
It seems a bit too hot for such a low speed. I think I applied enough thermal paste and spread it properly.
I'm using HWMONITOR while testing Prime95, and I selected the third option in the torture tests menu which includes RAM checks.
the auto overclocking tools usually increase the vcore voltage more than necessary. Voltage has a significant impact on temperature. Check the bios and set the core voltage manually. For a 4.2GHz frequency you should aim for around 1.2v, while 1.25-1.3 should help reach 4.5GHz. When it comes to temperatures, focus on the cores rather than the package. You should keep them below 75c, avoiding constant fluctuations or short spikes. For temperature testing (not stability), use a steady load. With prime95, the fft is minimal—just ensure you're using version 26.6, as newer versions aren't recommended for skylake because of AVX issues.

check the bios and set core voltage manually. for 4.2GHz you should aim for around 1.2v, with 1.25-1.3 you can reach about 4.5GHz.
temperature monitoring is more important than package specs; cores should stay below 75°C (consistent readings are better than occasional spikes).
for temperature testing without focusing on stability, use a steady load.
with prime95, the fft is minimal. make sure to use version 26.6 only (older versions don’t work well with skylake because of AVX issues).
Thanks bro! I’ll try these tomorrow.

Hi, my OC'd i5 6500 also shows temperature spikes. It reaches 75°C in a second but averages about 67°C. I'm checking the package temperatures because core temps don't display well on non-OC units. Are these spikes harmful? I was advised to keep package temps below 70°C.
