Trying to give you the details from memory....

Download ATIwinflash from techpowerup. Make sure you download the latest version.

1. Unpack ATIwinflash into a folder either in your desktop or in your root directory. Meaning C:\ATIwinflash. If you create a folder straight in C:\ and do it that way, it will be easier if you are not sure of navigating through DOS. So, just make a C:\ATIWinflash folder and extract everything into that.
2. Then grab the BIOS mod program from the begining of this thread and unzip everything into a folder.
3. Go to your C:\ATIwinflash and run the application. If you have trouble, right click and run as administrator.
4. Click the SAVE button to save your BIOS. It will get saved in C:\ATIwinflash folder.
6. Copy that BIOS file (it will be either a .ROM file or .BIN file - most likely a .ROM file such as BIOS.ROM) into the moded bios folder as instructed at the beginning of this thread.
7. If it is a .ROM file, just rename it as Original.BIN and run the mod utility.
8. It will create a Modded.BIN file.
9. Copy the Modded.BIN file to your ATIwinflash folder.
10. Now go to start and in type in CMD.
11. Once you see the listing with CMD at the top, right click on it to run as admin.
12. DOS command prompt will open up. Navigate back to C:\ using CD.. (two periods after CD) - may have to do this twice until you see C:\. Assuming you are not familiar with DOS prompt commands. If you are, please pardon me.
13. Type 'CD ATIWinflash' (without the quotes) to go to C:\ATIWinflash>
14. Type in 'atiwinflash -unlockrom 0' (without the quotes) and hit enter.
15. Type in atiwinflash -f -p 0 modded.bin
16. Reboot computer and check your shader clocks in GPUZ. It should show 1536 instead of 1408.

Alrighty, i'll give a try.

But just so im clear on this. Before booting up, i set the BIOS to "2" and set it to "1" after complete boot up, right?

Set it to 1 for flashing, and leave it there. 2 is failsafe, only use if you fubar 1.

That is how I did it. But seems that is not necessary. Set it to 1, boot up your comp, and then do your flash.

Thanx DaRookie . Got voltage control (using XPSP3 at the moment ) . yessir.gif nothing absurdly superior as yet but it's a work in progress . Any thoughts about max temps/volts on the HD6950 ?

You're welcome!

My 6950 doesn't go over 80c because I use the fan profile on MSIAfterburner. Without the fan profile it'll reach 88-89c playing Crysis.

I don't know what the max save voltage is but I'm assuming 1.3v at the moment. My max overclock with 1.3v is 960/970 - 1450. That's a pretty decent/good overclock, IMP. I can do 975-980 -1450 @ 1.4v but it's only for benchmarking. I'm still currently searching the web for "max safe voltage" for the 6950 but it's still to new to tell.

1.3v is Max safe voltage. You can put 1.5v but you need 100% fan speed.

Thanks Zealotkiller, I thought 1.3v sound about right.

Here's a link for the MSIAfterbunervoltunlock.exe http://www.xtremesystems.org/forums/...6&d=1291470526 . That MSIAfterburner will allow you to increase voltage over 1.3v. Becareful and good luck.
