Can't raise voltage of Sapphire HD4870 512MB

post #1 of 11
Thread Starter 
I just wonder if its locked or if there is a way to actually raise it. I am pretty sure if I was able to slightly raise the voltage I would get some extra power out of it. Any suggestions?

Actually these are the only 2 I have tried and in that order. First the trixx and after the afterburner. Trixx just the the slide bar locked and pressing the plus button did nothing and after burner didn't even show the current voltage.

did you go into the options on afterburner and enable voltage monitoring and "allow voltage control"

Just tried that too but nothing. The voltage monitor stays off and I cant do anything.

-EDIT-

Installed Ati tray tools for old times sake and checked it out. Now I see 4 options in the voltage. The current one and 3 others that are for undervoltaging.. hmmm

Nope. Tried all the possible software and nothing. I found some posts that people say something about bios but no luck there either. I guess I will just keep my stable 820 core.

Have you tried RBE? I used that on my 4850's to change the voltages and clocks. Just make sure you do some research on it first since flashing a card wrong can brick it. I'd help you out but it's been a while since I did mine.
