I'm testing an i5-6600K with a Rajintek Aidos (similar to hyper212) and an MSI z170m mortar. Running at stock voltage works fine, but I experienced stutters in GTA5 at times, which made me suspect CPU overclocking was needed.

After adjustments, I managed [email protected] and [email protected]. The situation becomes confusing. I turned off Intel Turbo Boost and scaling entirely, so it runs consistently. I’m using CPUIDHWmonitor and an Intel burn test. During the burn test, my hottest core reached around 65°C—expected—but then it throttled to 3.8Ghz. That’s still at 65°C.

I was worried but decided to revert to 4.5 just to be safe. I’m wondering if something is missing or if my temperature readings are inaccurate.

I'm using an i5-6600K with a Rajintek Aidos (similar to hyper212) and an MSI z170m mortar. Running at 4.2Ghz on stock voltage was fine, but I experienced stutters in GTA5 at certain moments, which led me to suspect CPU overuse. Eventually, I managed to achieve [email protected] and [email protected].

The situation became more confusing when I completely turned off Intel Turbo Boost and scaling, resulting in consistent performance. I’m using CPUIDHWmonitor and an Intel burn test. During the burn test, my hottest core reached around 65°C, which is normal, but it then throttled down to 3.8Ghz. That’s unexpected since I was only at 65°C.

I’m curious if I should have disabled the Intel Thermal Protection scaling in the BIOS, as it still appears to be working?

Could this mean I’m missing something, or is my temperature monitor underreporting the actual readings?

What kind of stress test do you think would be most suitable?

I've been searching online... it seems I might be reaching the maximum current capacity in the BIOS. I'll look into it later tonight. Also, I'm using an EVGA 750W PSU, which should provide ample power.

I believe it was the current draw limits. I turned it up and she still performs perfectly. I'm at 4.5GHZ at 1.275v, which is sufficient for me.
