Help overclocking a 7990 - Page 2

post #11 of 17
Thread Starter 
That stinks, from wizz's review on techpowerup we have the voltra chips along with Hynix chips so we can overclock them, its just figuring out how to unlock it. did you try to use the ASUS ARES 2 Bios? I think that would be a good try but we don't have that third 8 pin so I would be worried a little bit. Can you please let me know your results? I will post my results when I have tried it out.

The 3rd 8 pin is meaningless IMO as far as power, since a single 8 PIN can carry up to 300w IIRC. I tried the Ares 2 BIOS to no avail, but then again I was using ATIWinFlash, not RBE.

you don't use either of those to flash a 7990 tbh, just use ATIFlash although you can use ATIWinFlash & make sure you run with admin privies?

RBE is for older cards? this is VBE BETA!

HC_416 if want i'll dump my bios & send it you, max voltage is 1.3v, clocks unlock in AB 3.00 BETA.

just dump your bios in GPU-z & check VRM's & memory chips match this

Cool thanks, Actually I used VBE and made my own bios, but now when I try to open ATIwinflash, I get rom error. kind of confused but I will work on it, or if anyone has any advice please let me know. I am on WIN 8.1 so not sure if that is the problem or not.

I have not used it as AB works for me, just use AB & in settings unlock voltage / enable unnoficial overclocking.

if your voltage locked though it should let you change voltage as long as its supported?

Afterburner locks up my system. I use sapphire trixxx
