Adjusting performance on Skylake i5 6600K [Help Required]
Adjusting performance on Skylake i5 6600K [Help Required]
Hi, I recently overclocked my CPU to 4.6 GHz @1.260 (Bios vcore). CPUz displays 1.256 (idle) and 1.232–1.224 when under 100% load. So far it’s quite stable, with average temperatures around 50°C during the Aida64 stress test. When I attempt to push the overclock to 4.7, I encounter a BSOD. I increased the voltage to 1.3 but still experience crashes, so I returned to 4.6 GHz.
Under the BIOS settings (MSI Z170A M5 motherboard), I adjusted:
- CPU ratio: 46
- CPU voltage: 1.260 (Override Mode)
- XMP profile 1: @2400 (1.2 volts)
My questions are:
1. Is it safe to keep the system running at these settings continuously?
2. Can I reduce the Vcore voltage during idle?
3. Why does HWiNFO64 report lower voltages (VID - 1.110 volts max), while CPUz shows 1.224–1.232 and 1.256 during idle/underload?
4. Could you explain what’s happening with the temperatures? It shows a max of 75°C–80°C regardless of load, even when idle.
I also tried Adaptive mode, but it increases VID voltage to 1.3 while underload, yet the Vcore stays below 1.240 (CPUz). Thanks a lot in advance.
It seems like you hit the CPU's clock limit. You might try overclocking the base clock, but it’s a challenging process and also overclocks the RAM and other parts. You should calculate the RAM-Base clock ratio and explore more options. The best way to test the CPU is using Prime95, which assigns tasks to each thread in the CPU. If issues arise, Prime95 will display errors in the thread window. Run it for 2 or 4 hours to check for problems. Most stress tests only apply stress and stop there... try Prime95 instead.

Please note that you've hit the maximum limit of your CPU's clock speed. You can squeeze in more performance by overclocking the base clock, but it's a challenging process and also affects the RAM and other parts. You'll need to determine the RAM-Base clock ratio and explore additional options.

I forgot, select Small FFTs, and an error will appear like this:

I'm encountering issues with one core right away when I start the stress test, even after raising the voltage to 1.3. The version is 2.87, but it keeps failing. Other programs like OCCt Aida run smoothly at 1.260 volts and are stable. I'm not sure what to do...
