6950 to 6970 flash thread

[EniGmA1987]

ah ok

[C-N]

Sorry if it has been posted but there's a new Afterborner out

http://downloads.guru3d.com/Afterbur...load-2604.html

Don’t know if it was just me but with Beta 6 I had problems with profiles & power play.... they work great now & my card now idles low 30's. I fully removed the old version with settings before working out they have changed the way you edit the .cfg file to make things work properly read the notes at the bottom of the page.

Sapphire 6950 flashed with Sapphire 6970 BIOS, reference board and cooler.

6970 stock GPU Volts - 1000/1450




Overvolted to 1.3V with MSI AB - 1050/1450

[zalbard]

Are there still no unlocked BIOSes with higher overdrive and voltage limits?

Sorry if this is a bit off-topic...

I'm looking to upgrade to a 6950. Is there a difference between Sapphire or HIS? Can I use any of the 6970 BIOSes for both of those reference cards?

[SkItZo]

Seems my Gigabyte 6950 can unlock without a problem

It doesn't matter, as long as card has reference design.

EDIT:SAPPHIRE OWNERS BEWARE, YOUR VID3 AND VID4 ARE DIFFERENT TO ALL OTHER VENDORS, DONT FLASH OTHER VENDOR BIOSES

vid3 and vid4 are voltage settings at different levels in the card. Its why some users report artifact errors and some dont. Those that do, their card cant handle the speed and extra shaders at the wrong voltage level. Those that dont have problems, either have another brand besides Sapphire or their card is good enough to be able to handle the speeds at the different voltage

[zalbard]

You can tweak these voltages with RBE or just unlock your own BIOS. I don't see a problem...

you can actually manually unlock the shaders using your own card's bios?

New Powercolor HD6950 flashed successfully to ATI 6970 bios.

Running 1.2v (stock cooler has horrible contact) @ 80c unthrottled furmark. Really happy with how well it clocks, The vmem is near max stable, gpu still has a bit more in it before a new cooler.

Will any 2gb model 6950 flash over?

[LowRun]

Any reference model will.

In Italian's HD6970/6950 thread, successfull unlock XFX HD6950 1GB XXX.

Exactly this model (HD-695X-ZNDC) with single fan in the middle

just unlock script

on original bios


and this is the result

If that has unreference pcb maybe theres hope for people with 2GB non reference ones.

Gilgamesh,
Did you happen to get any before and after benchmarks to compare?

[fl0w3n]

Is there any calculation of success rate so far?

Has any one killed their card doing it? If so, any details?

That isn't my card: I have a Crossfire of Sapphire reference HD6950@6970

But 1Gb and 2Gb has same performance up to fullHD, and some time also over that, so HD6950@6970 880/1375 1Gb = 2Gb with same clock.

XFX 6950 1Gb XXX sell in Italy for 200-210 euro vat included (20-30 euro under reference 2Gb).

[EniGmA1987]

But I dont think you can use the regular bios from the 6970 2GB versions with a card that only has 1GB worth of chips on it. You would need a 6970 bios made for 1GB of vram, which there isnt one. So the two models aren't really the same.

Are you quoting me?

On HD6950 1Gb run unlock script on original backup bios. And reflash.

If unlocked shaders works, than works otherwise backup bios.

There isn't B plan

So as of yet there's no soft way of increasing the memory volts on these cards? (The VTT regs button in RBE is blanked out)

[nvmc]

How about increasing the overdrive limits on a 6950 bios? That way you can keep voltage adjustment in AB, clock past 840 without disabling idle downclocking, and keep all the 6950 memory settings.
I tried using RBE to put the OD signature from a 6970 into a 6950 BIOS, had to force flash it, and then Catalyst didn't detect my card. No big deal with the BIOS switch and all, but no success either. Anyone else have any bright ideas?
