Whelp, I think the whole "quality" % is a bunch of hooey. I just put my 84% quality card through the ringer and it sucks compared to my 73% card. My 73% card runs cooler and has zero artifacts at 1300 MHz on air. Just set it at 1.30v and off you go.

The 84% quality card ran hotter and at 1300Mhz would artifact so bad it would induce epilepsy. I tested all the way up and down the voltage range with the 84% and it's a complete no-go versus the 73%. Off to Ebay you go 84%!

Has anyone else noticed that the capacitor squeal on their 7970's is really loud, or is it just mine? Should I return it? It's really audible during any 3D app. I can probably notice it even moreso than normal since I have a silent system under water with a waterblock on the 7970...

Anyone, before I RMA it?

After much following all the ASIC posts and there ability to over clock or lack there of, it varies so much that I'd have to concur with you Vega. By now we'd have seen some common denominator but there's nothing to point to a solid conclusion of performance gauges based on the ASIC as of yet.

Mine at running at 1.17 in afterburner at 1100 / 1550 now stable without issues.

However the damn top card is getting to 75 while the other barely hits 60. Both have auto fan profiles. I do not understand!

Well, my diamond ref is doing just fine so far. 1300 Mhz, 1650 mem @ 1.3v. The ref cooler actually does a great job on this series, ek block will be here tomorrow though.

Swap the cards around, they'll even out.

Higher quality asic doesnt need so much voltage,
try 1.2V

Does everybody remember the ASUS OC test bios? Well Here is the final version on that used on retail reference ASUS cards.
Ive flashed both my cards and just feels better knowing its not an incomplete "test" bios.
Also it is significantly different in size compared to the test bios.

Asus.HD7970.3072.111220.zip 41k .zip file

Penguin, pls add to the OP kind sir smile.gif
