Voltage increase on 5770

[guggas]

So I'm seeing some results overclocking my vapor-x 5770 but its not very stable. How would I go about increasing the voltage on the gpu?

Thanks.

Try to run MSI-Afterburner and see if you have the option of changing voltage. You should but I'm not sure. Alternatively I think you should succeed in ATI Tray Tools...

I've never used it but EVGA Precision might also...
