6950/flash help

[Phase]

Right guys this is a good one for you!

I have 2 xfx6950s, If i flash them to 6970 i get artifacts all over the place.
So i have found a xfx bios thats just got the unlocked shaders that works A1.

So what i thought is overclock to 6970 speeds. I cant find a bios that will go that high.

I have found an Asus 6950 bios with unlocked shaders that will let me get way past 920/1375 and the cards will do it no problems at all,BUT for what ever reason the eyefinity will not run.

What i would like is with the xfx unlocked shader bios i have, up the max clock settings but if i try and up them with RBE i just get BSOD (remember this is just the max setting in RBE i havnt changed anything at this stage)

Does anyone have a 6950 with the unlocked shaders and able to OC past 900/1350?

Been up half the night and have a little more info.

No matter what i do if i edit ANY bios stock or a DL from the net i get a BSOD when i try to reboot.

Also the 2nd GPU will not over volt! Its stuck @ 0.9V

The cards on there own are ok they go 960/1335 no problems at all.

They are the 2gig ver.

I have tried to underclock but still artifacts, But as i have said the cards on unlocked shaders and run one at a time will go past 900/1325 with no problems.

The problem i have atm is the 2nd card will not over volt.

The reason why they artifacts is due to the memory, If you used the same bios you could get faster speeds.

They are stock coolers.

Right think i have sorted it. So this might help other ppl with the same problems.

Download this BiosThis is 6950 Shader unlock only

Then Google MSI afterburner 2.20 beta 2
In the settings untick 'Synchronize settings for similar processors'
Then set each card and your sorted.

I have just been stress testing @900/1338 @1.1V

What i have found is if i upthe voltage i start to get artifracts. Might be the stock coolers?

Its sorted mate. Look at the post above yours

We prob have the same cards from the same shop

I run @ 5760x1080. Setting the clocks has taken Portal2 from 89 FPS to 120 Think thats max.

TBH it doesn't scale like that. It looks like 3 1920x1080 screens. Its only whan you start a game it look kool.

I could never go back to one screen, Its so easy with loads! you just move stuff out the way

I have just found a cracking tool for 6950 ppl. It allows you to up the sliders in CCC and still only flash the shaders.

You can do this
Regedit

Or use this tool and it does it for you
regedit tool

The tool will let you set the base clocks. I have mine set to 910/1345 1.1V loads these as it boots.

Its about time i have been messing about with this for about 20hours lol.
