post #21 of 437
There are a lot of Sapphire Cards on ebay if you guys could not find them online, they are all around the 300 dollar mark so not bad.

gaming works fine.

hoping for timings bios later on.

I'd like to know a couple of things.

Stock voltages, the differences in gpu and vtt registry values, if any.

Also what was your max oc running a 6950 bios, what is the max oc with the 6970 bios?

Thanks

I see some guys reporting artifacts with atitool..
This should fix that...

ATItool> Settings> Artifact scanning> Check "Use old(more compatible) scanning method.

This is assuming that games do not show any anomalies.

havent tested much, just gamed.
and havent had chance to check for max overclock yet.
my max with 6950 was 920mhz bench and 890 games.

Basically waiting for afterburner to support voltage adjustment.

So no tools out there that will read voltages?

I just tried rbe, no joy on the voltage registries.
As of now I guess, no info on stock voltages?

tested,
925mhz on one card 6950
950mhz on unlocked 6950(6970)
run trough and cracked 9k

Previous attempts has shown 925mhz being a max on the 6950.
so better.

Nice

How's the memory handling the speeds, get any more out of it?

i got 880/1320 stable overclock on the 6950 bios , 6970 bios let me push them up to 905/1440 stable in msi afterburner without voltage control yet . but when voltage control is available through software i can see this card doing 950+/1500

never seen any artifacts on this card .. only thing when i overclocked my ram to 1450 it skipped frames quite often so i just backed down to 1440 and it runs perfectly .

According to AnandTech, it's 1.175v load for the 6970 and 1.100v load for the 6950, with 0.900v idle. But as of yet i'm not sure if there is a way to monitor load voltage on these flashed cards, except GPUz maybe? Doesn't 5.0 support these cards?

Seems like great results are being seen. So no one here is artifacting at the "stock" 6970 unlock? This is good news. I would think that once you can adjust voltages, 1000ghz would be possible?

I see... It makes sense. 6950 overclocks better with 6970 BIOS because 6970 default voltage is higher than 6950.
Well.. I think I should check computer store soon before this card running out of stock. biggrin.gif
