Hi wazgoingon? "3) unlock the shaders with the 6950 bios and just oc from there?" ,this is good! If you saw "704" shaders at default hd6950 state, it mybe cause by missreading of GPUZ. AMD just use a new register to show the dual core state? Weird..... If this is the case, you will...

Interesting. Infact, if you see "768", that means you've got the extra shaders which you expected after flash the 6970's bios to your v1.2 6950. 6900 serise has two core inside: 6950 = "704" * "2" = 1408 shaders 6970 = "768" * "2" = 1536 shaders "2" means two core enabled. As you can...

Yes, it is better to do that, in theory. But I have to say it is too complicated/dangerous to do so. If you wanna play around with the memory timings, you need internal hardware document , manufactory level. Otherwise you have to forget about it. The thing we can do is reducing/increasing...

Yeah , the chance is prety small, but not zero. http://www.techpowerup.com/reviews/HIS/Radeon_HD_6850/

My point is you can extend the code to make it also work on 5850/6850 BIOS, to bypass the software mask settings in these BIOS.

You can try to modify the original 6950 BIOS for you card, it is safty.

Hi W1zzard Yes the code is looking good . But there is something else. Infact AMD apply such mask settings in BIOS since HD5850. 5850 : 4a 8d 54 22 ff 03 49 6850 : 4a 8d 54 22 7f 00 49 6950 : 4a 8d 54 22 ff 0f 49 What do you think?

NO! Just the mask settings, didnt touch anything else.

Yes it is right step, of course it will work. But Im not expect all 6950 users have such experience and capability to modify the binary code directly. It is too dangerous for most of them to DIY BIOS code without 100% sure what they are doing. I just want to do the dirty work for them and...

Thank you very much for the suggestion. But it is a bit complicated. How to tech the user to calculate and restore the checksums for AMD/ATI bios image? RivaTuner have a good patchscripts system, but it can only mod the BIOS for NV.

Any binary editor. HxD editor, this one is freeware.

Saphire 6950 BIOS. I had build a small utility to do this BIOS modification, beta testing stage. You guys can DIY the 6950 BIOS for you own card by using this utility.

OK , here we go. Not recommand other 6950 users to use this BIOS, unless you sure your original 6950 bios identical to this one.
