[tyrael64]

update: playing stacraft 2 10min with the crossfire, computer shut down and the cooler of the vga go 100%

Try underclocking back down to 6950 speeds?

 

[tyrael64]

i leave the clocks the same, but increase the fan speed, and apparently was corrected
There is one card that is very close to the other and becomes very hot

I have a Sapphire HD 6950 and got a "Could not erase ROM" message.

Used the "atiwinflash -unlockrom 0 followed by atiwinflash -f -p 0 bios.bin" method it worked.

Before and after pictures attached.

$293 free shipping at Amazon (no tax in CA) for Sapphire and HIS versions...

Why did I get that silly 6870? It's straight to Ebay for that card...

So after this card is flash to hd6970. I should always stick with hd6970 driver from now on?

it's the same driver

Tried this with my 6950's... Both of them Sapphire and now working as 6970's..
Benchmark results confirm much improvement...

Cheers

Hey guys! I have a Sapphire 6970 now. If i buy a 6950 flash the bios to a 6970 can I use it in CrossFireX with my existing card without problem? What do you think?

yep, should work fine

Nice, thank you so much! I'm ordering a 6950 now

Nice, but will the pci-e molex 6pin + 6pin differ than the 6pin + 8 pin?
dual 6 pins on the 6950 are enough to use same 6970 specification for long time without issue?

i updated the article about 2 hours ago with power consumption testing

 

[W1zzard]

updated the article with link to easy to use flashing tools that also includes the right build of GPU-Z

Nice work W1zzard


Can I just clarify that running +20 is fine for gaming and benching on a day to day basis.

I have a 620w Enermax Liberty PSU

it's slightly over the spec, but in my well educated opinion that's perfectly safe.

If u got an Asus 6950 and mod it into an 6970, will you lose the Asus Voltage Tweak tool since you swich bios?

yes, use the ASUS 6970 bios from the vga bios collection in that case

thanks W1zzard, I've just tried the flash_to_6970 batch file and found it to work with my XFX HD6950! (it was locked. I did get confused for a sec when it told me to switch to the "2" position just a typo, right?)
I've yet to test for artifacts, but I'll test it to see how it goes.

Besides the power consumption concern, I'm wondering how the HD6950's stock cooler will hold up. The ones on the 6970 do have a slightly larger fan, am I right?

"Also the card uses the same cooler and PCB as the HD 6950 reference design."

looks the same

EDIT: whoops... slight fan difference.. someone should test CFM, RPM, fan %

typo indeed. thanks for bringing it up. i fixed it in the download

 

[easyrider]

I really hope this flash is successful 24/7 its still early days on what if any problems may arise

Hey guys,

because of that nice "feature", I'm thinking about buying a 6950 and unlock it to a 6970.

Now my question, can I use a 6970 together with my 5870 in crossfire ?

And finally, do you know where I can find a recent "crossfire yes/no matrix picture" ?

Thanks a lot !
