I don't have onboard graphics, but realistically speaking, if I can't even flash from DOS (by which I mean proper DOS, as in the OS that was obsoleted by Windows 95, not a Command Prompt window) I'm not sure how safe mode is going to help.

I seen somewhere that u can flash back in bios with USB stick.I was going to do it before I flashed mine back which was just total luck.
Will send you link when i get home, I think i have it bookmarked somewhere.

If that doesent work Can you use a friends computer with onboard graphics?
I thought i had bricked mine and was minutes away from losing the rag, I didn't have a switch for my 1 gb6950 so was pretty stupid of me to attempt to flash in the first place.
I couldn't boot into windows after flash went bad and couldn't get into windows without bsod.
I ran into safe mode and the computer booted into windows with it's on board graphics, unistalled the drivers and rebooted( the computer then booted using on board graphics)and re flashed.
I have tried this a couple times to make sure it wasn't a fluke.

Can an Asus ATI Radeon HD 6950 DirectCU II 2048MB have its shaders unlocked?
According to some places (including OcUK shop) it can but some people on here say no.

Is there a definative answer please?

Can you not boot using the good bios flip the switch then try flashing again?

I want to get a HIS 6950 2gb card, But they're currently sold out on OC. Does anyone think the restocked cards will have this mod patched?

Looking online it seems these cards are being sold out pretty quick, been monitoring with the view of getting a 2nd Saphire HD6950 but all gone, the ASUS ones have gone and not many of the others left.

seems they are going to be replaced with rev 2 which probably wont flash.

Managed to get my Saphire this morning but not from here, started off with 30 in stock last week and now down to 10, cant see them getting more to be honest.

I think the rev 1 are being phased out

addictedtopain · 28 Apr 2011 at 15:53

Ahh Ok, I best get me one quick!

there's either an XFX or Asus left in stock, can anyone recommend one?

Can I xfire a 2 gb his with my 1 gb his 6950?
Or should I just get another 1 gb 6950?

Just bought one of these - http://www.overclockers.co.uk/showproduct.php?prodid=GX-119-MS&groupid=701&catid=56&subcat=1752

- hope it unlocks. Tempted to get a second though!

Do these get much hotter when flashed to a 6970?

Mine went a couple of degrees hotter under load, but then I just modded the original BIOS to have the unlocked shaders and this seemed to give the performance gains with a smaller temp rise. (clocked it up to 6970 levels too I think itts just RAM timings and power regulation that is changed otherwise)

Yes the def unlock and temp rise is only small afterwards. Goes up a bit more of course if you overclock it further

I only tested using Heaven DX11 Benchmark 2.5, around 5°C more, not a big deal really, I was more worried more about the higher volts and the higher clock on the memory to be honest.

Unlocking is not guaranteed remember I have an XFX card here that does not unlock. With the shaders unlocked it artificates badly and this is a revision 1 card. My Asus unlocked fine and runs as a 6970 but in all honesty the difference in game is very minimal..

Nigel014 · 29 Apr 2011 at 19:24

Ordered an asus 6950 rev 1 card the other day, fingers crossed the shader unlock goes well. I heard a lot of people's cards were dying after just a couple of week with the 6970 bios so I'm just gunna do the shaders and overclock it manually.

you can but the 2gb card will only be able to use 1gb so best off saving the cash and get another 1gb

Ran the batch file from here: http://www.techpowerup.com/articles/overclocking/vidcard/159

and it has unlocked the shaders on one of my 6950s, how do I make it work on the other?

Lum · 1 May 2011 at 18:40

Copy the batch file, then edit it using Notepad. Look for the calls to ATIWinFlash.exe, there should be two:

ATIWinFlash -unlockrom 0
ATIWinFlash -f -p 0 <filename>

Replace the 0's with 1's

ATIWinFlash -unlockrom 1
ATIWinFlash -f -p 1 <filename>

Bradmax57 · 3 May 2011 at 14:26
