Does ASIC quality mean anything anymore?

I am at 90.2% but I find that I have to pump a ton of voltage to get a decent OC.

And anytime I do a benchmark or graphic intensive game using Trixx I'm at 1.056v for VDDC but GPUZ reports .992 VDDC, and that's with using the 20% increase on board power.

Even then at such a low reported voltage, I'm at 66c max load. Is this good or bad? And what on earth is going on with the voltage?

I'm starting to think, I need to send my 2 ASUS DC2TOP back for Warranty

with 12.6 it works stable as a stand alone card

but if i set it to Crossfire, it crashes way too often

I still can't quite figure out if it's really a hardware issue or a software issue

Only stable drivers for me are 12.4. 12.6 & 12.7 do not work well for me.

FYI

For using 1 gpu, PCH voltage at auto or +.025 above auto.
2 gpu's (crossfire or sli) PCH voltage up to +.050 - +.075

So if your PCH voltage is at 1.050v in bios on auto, when trying to use 2 cards try 1.050v + .050v - .075v = 1.100v - 1.125v

3 gpu's 1.125v - 1.150v

Edit: also if that formula board has the extra molex connectors for supplying extra juice to the PCI-E lanes, USE THEM

I have a single card and my voltage is at 1.156 with my clocks at 1110/1500. I actually just upped my voltage a few points because it seems to stabilize my card better with these newer drivers. Its been crashing every now and again since after the Catalyst 12.4, but like I just said, less and less often when i increase the voltage by small amounts. But other then that and it hasn't crashed yet with my current voltage setting, my card is running beautifully. These newest drivers look and perform really nice.

i'll have to check the BIOS to see what they are set to

i did this already, it's not making any difference

it might be the BIOS

i even under clocked both cards to stock 925 Mhz with stock voltage and it is still does the same thing "crash" with the lines patterns, and the only fix is to hit the hardware reset button

Well "lines patterns" usually means Vram isn't stable. Have you tried raising the Vram voltage for the cards? Default is 1.600v. You can try using 1.631v - 1.650v. I use 1.650v for running 1700mhz on my cards, but mine are on water and stay cool so I'm not worried about the Vram getting to hot.
