How do you lower voltages on VRM?

post #1 of 5
Thread Starter 
Is it even possible to lower the voltages on VRM?

I have:
7970
5970
5870
6950 x2

VRMs provide power to your GPU core and memory. Yes, you can reduce voltages but it will lower highest stable clocks.

is it possible to lower the voltages for just the video RAM and keep the clock voltage the same? I only care about the clock voltages

What is a "clock voltage"?

You do NOT want to modify VRAM timings and settings unless you are very experienced. This requires firmware modification.


You can lower core voltage. Like I said, it might lowers the highest possible clock at a given voltage.. If you are not at the highest possible clock at a given voltage, then it depends.

For some 6950s such as MSI TF and 7970, yes. It will go as low as what is set in vBIOS.
