i'm wondering how to overclock the card past its limits now; the only method i know of is RBE but after flashing the driver doesn't recognize the card any more...
you can go past the 950/1450 limit using an Asus card bios and the latest Smart Doctor



you can find asus 6970 and 6950 bios's in this thread

but the overvolting doesn't seem to work

damn :( the 6950 bioses have lower core voltages than the 6970 bioses, this new bios is set to 1.100v but the last one was 1.175, I cant get anywhere close to the oc that I just had, any way to have a bios that can run a higher voltage than 1.100v?
Where did you find it? Rbe (unsupported card) is not showing anything different from the 2 bios.

Maybe we should change tactics and edit the 6970 bios instead of the 6950 bios.

Would it be better to edit the 6970 bios by reducing the memory timing,etc.. to make it safer for the 6950 cards.

This way CCC thinks the card is a 6970 and gives us the Overclocking capabilities of the 6970... and we would have the increased voltage...

Just a Thought....;)

for 5 euro less than the cheapest 6950 availiable here in the netherlands,
i bought myself a perfectly working P45 mainboard + E8400 + 4gb 5ms ddr2 800 + 4890 toxic...
the second 4890 toxic would bring me VERY close to the 6950 performance if i crossfire them..
and on top i get a mobo+cpu+mem with it... what more can i wish for :)

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.
no, those cards dont have shaders configured via bios

Thanks W1zzard, just unlocked the shaders on my ASUS 6950 with your script :D
My GPU score in 3DMark 11 increased from 4519 to 4903 :) (With 885/1380 as clock)
Thanks!

I just downloaded an Asus 6950 bios, unlocked it with the script and flashed.
Now with smart doctor I can go past the panel oc limits and the overvolting seems to work as well! (at least, temperature jumped 20° when setting 1,3v)

I had no issues doing the original bios flash posted here on my 2 Sapphire 6950s. I am able to push them to 920/1400 with no issues in 3DMark Vantage and 3DMark06 (I know, I need to download some newer benchmarks). However, my cards now idle around 60C, while they idled around 42C on the original bios. Did the bios flash increase my core voltage, causing the huge increase in temps? I like the performance bump, but not at the expense of heat / fan noise. Is there an easy way to reduce my voltage on the 6970 bios, or do I need to go back to my earlier bios and then do the shader hack?

rui0317: Thanks so much! I just flashed my Sapphire to your 6950 with unlocked shaders and all my artifacting is gone.

I guess this along with others' experiences pretty much demonstrates that the artifacting was due to the 6970 memory timings.

no dx11 support will make the 6950/70 much better even if u xfire.
Next year's games like bf3 will have native dx11 support, but will also include 10 so it's not a total loss, but that's the problem with going with the super fast old cards.

Downloaded 3DMark11 Basic and ran the standard test, got the following results. I have 2 Sapphire 6950s in crossfire, both have the 6970 bios and are running at 920 / 1400. I have no idea if these scores are in line with other crossfire setups since this is my first time to use 3DMark11. Any other free utilities I can use to benchmark my setup?

Still concerned that my cards are around 65 degrees at idle and ramp up to 85 degrees under full load (although that's with the fans never going above 33%, which is the point where it gets too loud to be bearable).

Hey Tuvok.. which Asus bios did you download ?
or, could you upload the modded Asus bios you are using now ?

thx
