Hi everyone,
As mentioned in the title, I’m getting a new 1070 graphics card and have been looking into how the CPU might be limiting the GPU performance on older i5 systems.
I own a 3570k, an MSI z77g45 motherboard, and a Hyper 212, which I’m attempting to overclock to extract more performance.
Even if it doesn’t cause a bottleneck for my GPU, I still want to push the overclock further.
In short, what’s happening is that once I run Prime95 with the 'small fft' setting, my CPU temperature quickly rises to around 70°C, causing it to drop its frequency from 4.4GHz to 4GHz. It then stabilizes around 75°C and fluctuates between 3.8 and 4GHz.
I’m wondering how to achieve a more stable overclock. I’ve read that these CPUs can still run into the high 80s under load and remain functional, but I want to avoid throttling.
I believe I solved the issue. The long duration power was initially at 77, then increased to 95, and I haven't adjusted it down since.
Do you know how to adjust your BIOS settings? This is important since enabling throttling can lead to the CPU slowing down when it gets warm. If you can access your BIOS and disable power-saving and throttling features, you can maintain the clock speed you want.
Do you know how to access your BIOS? This seems like a situation where throttling is active, which can lead to the CPU slowing down when it gets too hot. If you can enter BIOS and disable power-saving and CPU throttling features, it should maintain the clock you want. It’s frustrating—I’ve spent two hours searching online trying to figure this out. I can set it to 4.4GHz, but once temperatures reach 70 it drops to 4GHz and at 75 it goes to 3.8GHz, never exceeding those levels. I’m sure there’s a setting I missed after going through my BIOS, but I still don’t understand.
