Bes thing would be to try using the W1zzard script from TPU as that one looks actively at the BIOS for the correct location of the shaders in the BIOS.

Thanks, I'll take a look.

I have just flashed my Asus OC 2GB 6950 to 6970, however one of my DVI outputs is not working for my second monitor, I have a dual screen set up with DVI connectors. windows recognises there is a second monitor attached, but no output is displayed on the screen, is there a fix for this?

Did you flash it with the latest ASUS BIOS from the list on techpowerup.com by any chance?

I made that mistake.. that BIOS is for a different card. Use the generic Sapphire one and you'll be fine.

Just flashed my MSI 6950 to a 6970 using the method in the OP and it all went nice an smoothly. Heaven ran perfectly happy at 880/1375, but the temps were getting rather high (89 degrees when I stopped it), so dropped it to 840/1300 for the time being. Heaven has it hitting about 78 degrees with this set up, but my case air flow is not great. I also dropped the power control to -10%, which doesn't seem to have affected it at all in terms of stability, but will it help the temps at all?

What's a reasonable temp goal for these cards? Wondering if I might be better just unlocking the shaders rather than the full 6970 flash as this increases volts doesn't it? Also, can anyone tell me how to find out what the voltage is that it's running? Can't see anything in MSI afterburner or GPU-Z.

Never mind, reading through some previous posts, looks like these temps aren't far out. Got it back at 880/1375 with fan at 40% and that's holding at 78 degrees during Heaven now so think that's ok.

I still have power set at -10%, there's not sign of any artefacts, but most people seem to be going in the opposite direction with this. Is this a bad thing? (please excuse ignorance!).

yeah I did, Saphire? is there not an asus one that works for it? also idle temps are about 70C, which apparently is normal.. :S, Looks like next upgrade is water cooling!

There are 4 Asus BIOSes on that download page, the one you used is, I think, for an eyefinity card. Feel free to try the ones you haven't already tried

I know the Sapphire one works though.

used the wrong bios, Flashed with different one and it worked, thanks!

Lum · 24 May 2011 at 01:53

Out of interest, which one worked? Got a link?

hi. i've got two questions.

1) can "ASUS ATI Radeon 6950 OC 2048MB GDDR5 PCI-Express" be unlocked to 6970?

2) http://hw-lab.com/unlock-radeon-hd-6950-2gb-tested.html
can this method be used to unlock the 6950 asus card?

thanks.

I have that card and I'm using the Asus 6970 bios flashed with RBE and it works fine. Not all cards can be flashed and some may artifact once flashed there is a certain amount of luck invloved but the majority seem to work ok.

I'm looking at doing this to my card, but I'm worried about the increase in power when playing games.

Looks like I'll be upgrading my psu before I do this, which means ill be upgrading a few other components as well.

Phase · 25 May 2011 at 23:36

I have run two 6950s/6970s on a 650. So i wouldnt worry.

Coomber · 29 May 2011 at 17:58

I have just flashed my new MSI reference 6950 to a 6970 using the batch file available from TPU. Whats the best way to benchmark this bad boy (I have a code for 3DMark 11 with it, is that any good?)

Also anything else I might want to tweak after flashing it...played a few games and it seems stable.

Lum · 29 May 2011 at 19:15

Maybe try FurMark?

SqualidChimp · 30 May 2011 at 12:44

furmark and 3dmark are the standard ways to go I guess. and 3dmark is at least slightly pretty/entertaining. I suppose furmark is too if you like fuzzy doughnuts...

Coomber · 30 May 2011 at 14:40

Doesn't look like I'm getting the right results (I ran it on the Performance setting)

Lots of fields say 0MB or 0Mhz?

Sasco · 4 Jun 2011 at 12:24

I know the MSI R6950 Twin Frozr III Power Edition/OC isn't reference and has different clock settings, but has anyone been able to use this method to get the shaders unlocked etc?
Cheers!

Do it manually
