Well heres the news: i just bought a 2gb CNDC Model (XFX) standard clocks 830/1300. Well im pretty good with Electronics and Computers so i decided to do the HArdware mode, Voiding my Warranty ect.
So i bridged the 1-3 over the IC with a silver curcuit pen, very, very tricky work as the IC has some 'Rail grooves' that could infact carry the Soloution to the wrong LEGS on the IC's, Lucky i had some alcohol and a magnify glass.
Regardless, Dont do it, these IC's are Lazer cut on this model, i does infact take the flash after the fact but you will not unlock the shaders. SO DONT DO THE MOD.
BUT....When going back together i cleaned off the old thermal Paste and put some good ol' Artic silver II on the GPU, made sure i sequence tightened the Skrews for even spead.
I then opened up my clocks using this method here

And installed MIS afterburner so i could monitor temps in game, you can also do a voltage adjustment, but i have not.
im currently at 900/1325 and have not hit the Core clock roof yet (then i will notch up the memory).
But to be honest even at these clocks im getting 98% ultra settings no MSAA solid 60 FPS in BF3.
Temps never go over 60 c average about 58.( Fan speed at 60).
If your not bothered about scratching your Warranty, I advise to re-paste your Stock Cooler and GPU with the best stuff you can find and over clock this Bitch...Forget about the Shaders....im allready very very happy going from Tri Fire 5870 to single 6950 2gb. the extra 2 GB and the over clock makes my Game play so much better.
Fantasic card, even if its locked, would love to water cool it, but the expense pays for a 7970. so not worth it.
