HD7950 revised with reference HD7970 PCB club - Page 6

post #51 of 846
Just to mention, I flashed my Gigabyte Windforce 7950 with the Gigabyte 7970 reference bios (1000MHz core/1375MHz memory) over at techpowerup.com:

http://www.techpowerup.com/vgabios/index.php?page=1&architecture=ATI&manufacturer=&model=HD+7970&interface=PCI-E&memSize=3072

and it's running rock solid stable.

I know this is a tepid overclock compared to what the card is capable of, but I don't know of any tools for modding Southern Islands bioses yet. Just wanted to let anybody with the Gigabyte card know that it worked perfectly, gives a nice little boost up from the 900MHz core speed the Gigabyte 7950 ships with, and you don't need any O/C'ing software. The Gigabyte Windforce 7950s also come with a dual bios switch in case you're squeemish about flashing the card. I also tried the VTX3D bios (1050MHz core/1425MHz memory) and although it seemed to run fine, it did seem to hiccup a little bit from time to time. I suspect it was either the voltage was not quite high enough for the ram overclock, or my memory just won't got that high completely comfortably. The MSI 7970 bios f@cked up the display (funny characters in command prompt when you first turn it on) so I re-flashed back to the Gigabyte 7970 bios. I'm about to try the XFX 7970 bios, as it is also running at 1GHz core, but with the 1425MHz memory of the VTX3D bios, just to see if it's my memory that doesn't like 1425MHz at reasonable voltage.

On a side note, the Gigabyte Windforce seem like a great value, as they're aggressively priced and they have a very good cooler/fans. It also seems to run very quietly, even under load. It may be the best value in a 7950.

Good to hear that card is working out for you.

The Gigabyte Windforce HD7950 isn't built on a reference HD7970 PCB


Did you notice if your shader count went up after doing the flash?.

As it seems like nobody knows about it, check this out; http://forum.techinferno.com/vbios-patcher/1768-vbios-patcher-general-discussion-feedback.html its a utility for editing 7 series vBIOSes. The app is still under development and its support is very limited so any feedback, support, vBIOSes you can offer I'm sure the developers would very much appreciate.

Would be awesome if those bright minds can figure out away to unlock our HD7950s to HD7970s.

Do all the recent MSI TF3's come with the 7970 PCB or only the OC'ed variant?
And would you recommend it over the Sapph 950 version?

Some might find this interesting aswell:

Thanks in advance,
