nothing

same performance

There is a difference, the memory on the 6970 has different timings. Given this actually prevents some people who flash running a 6970 bios.

Also clocking the 6950s will not up the voltage, the 6970 bios will run higher voltage by default.

Indeed. They perform the same, but are not just an identical card. There are differences, even if they aren't that big.

Just flashed my Sapphire 6950 to a 6970 and was fine in heaven:

No idea why my minimum dropped so much though.

You have to allow it to run once 1st and then count the benchmark on the 2nd run. You will find your min FPS goes up then.

question
both of my cards are flashed, if i flick the switch back on both and reboot, they boot as 6950's ?
if i then switch it back, with the flash still be there ?

I used the script from wizzard that takes the original BIOS and unlocks the shaders without changing voltages and clockspeeds and reflashed my card. Not stuggling for FPS in anything I play anyway and it seems a bit safer.

That is what I am going to do with my sapphire card when it arrives tomorrow. Did you still flip the switch before flashing the bios?

mine was ont he right one by default (HIS)

Haven't touched the switch, backed up the original BIOS before doing anything - and patched that, rather than the 5870 one.

Just flashed my Spaphiore 6950 - had to use DOS to do it but it was all really straight forward. In fact the most complex bit was working out the file extension for ATiWinFlash!

I'll probably not put the extra 20% load on just now as it runs BC2 cranked up on 1920x1200 and will probably only move the slider up somewhere down the line when I find something more demanding to tax it!

Seriously - this is sounding like I should cnacel my 6970 order and get a 6950 and 'simply' turn it into a 6970? Right?

Not just because you can flash it - performance wise the extra €70 (or dollar) does not justify the expense.

the 6950 will be about 7 to 10 % below the 6970 and the price gap does not match that.

I have just bought the MSI Twin Frozr II 6950 and with a bit of overclocking and not modded it matches a 6070 in every bench.

WIll post a review within the week and will try the 6970 mod on it, there are no dual bios and no Switch so don't have the luxury of "switching" back.

Just ordered a 6950 fingers crossed.I think I will just go the unlocking the shaders route if I can when it arrives on friday :-)

I flashed my sapphire 6950 with the guru3d flashing download, after doing this I had a quick game of wow and after maybe 20-30 minutes there where some graphics glitches, the flames graphics where sometimes appearing in the wrong place but everything else was fine with no sparklys.

Any idea if this would be a gpu, memory or duff unlocked pipes problem?

False alarm, testing it in a bunch of games + unigene and furmark and it's all fine

I would be careful, maybe someone else can say for definiate but if it's MSI's own custom design PCB and uses different VRM's etc, if you flash it the bios could brick it . . . . thoughts?
