Hello, your overclocked i5 750 struggles to run at 3.9 GHz continuously on the H55 board. After stress testing with CPU-Z, it drops back down to 1.65 GHz and then returns to 3.9 GHz after a short period. Around 1 minute, C1E and C states are disabled. You’ve tried another core clock setting (3.6), but the issue persists. The stock speed stays stable at 2.67 GHz with a thermal max of 3.9 GHz at 69°C. I don’t have any clear advice, but maybe check the BIOS settings or consult a specialist. Thanks!

I completed a BIOS reset and update. The Intel Turbo settings are now visible. I turned off IST and speedstep (also new). After trying again, I noticed the multiplier dropped to x9 at 1.65GHz. Any idea why?

It's experiencing thermal throttling. The maximum CPU temperature reaches 72°C. A slightly lower temperature, around 65°C, might prevent it. Also verify the VRM temperatures; excessive values can lead to throttling.

my motherboard can't handle VRAM temperature measurement, so i'm connecting the chassis fan straight to it. my 3.9 GHz is running smoothly without throttling, but i expect the VRAM to reach up to 100°C—maybe around 70°C or higher when I touch it.

A VRM can manage temperatures up to 100°C. However, if the BIOS limits performance at around 70°C, that's where throttling occurs. Nice work figuring this out! Great presentation!
