EVGA GTX 480 Furmark 1.8.2 high pitch noise?

[fang_laluna]

Hi,

I just bought EVGA GTX 480 and it's under water now with EK block.
I want to start overclocking the card but when I installed EVGA e-leet and MSI afterburner they're not showing the core voltage and core clock?

What's wrong?

Thanks

MSI Afterburner will need you to go to Settings and unlock overvolting.


Eleet is unknown to me, so I cant help you there.

Thanks but the core clock is not showing?

lol, thanks so I have to adjust it from shader?

EDIT: When I started stressing the GPU using furmark 1.8.2 it makes high pitch noise, is that normal?

Yeah the core clock is half the shader clock. Up the shader to 1600 and your core should be at 800.

Any stress testing will cause the gpu to run at full load and possibly cause the hardware to start acting 'differently'. I've heard high pitch noises from mine and it's still cool

High pitched noise is capacitor squeal under heavy load, its completely harmless and something you should ignore.
