Edit: Running 1220 Core, 1850 memory. 1.625 memory voltage, 1274 core voltage (100% stable, I can lower it to 1258 or so with no crashes but the occasional artifact - yes I know I have a crappy GPU which would benefit from WCing but I'm waiting for a new CGN/Kepler before I go multi GPU and watercoolz). Thanks!
Edit: How do people get more than 1.3v on the core?

At 4xMSAA I'm pretty sure a minimum of 54 on the B2K 64 Player maps is incredible.

Apologies if this issue has already been mentioned in this forum!

bigeyedsmiley.pngAIB partners changed capacitors on HD 7970 cards resulting in compatibility issues.bigeyedsmiley.png

Caution.
We have been warned about a change on some AMD reference HD 7970 graphics cards (AMD 109-C38637-00) which now use one capacitor slightly higher (about 1mm higher, with blue instead of pink markings) than what it was originally.

The asus oc bios allows me additional over-voltage of about 70mv.

My ? is what core clock can you get with the 1.37v idle and 1.31v load?? I have 1 of mine on water and will have the 2nd on water this week also. I may flash to get more out of it too. Max temps with water is only 44c if it's 75f in my living room.

Just wondering if you maxed out at say 1250core and then after the bios flash you were able to get 1350???

Dame, mine has the caps with pink on them. Maybe I will replace them all with the blue ones and my coil whine will go away. I can put my EK block in a Cnc mill here at work and make room for the other caps. Hmm

If i understood the article correctly, pink is good, blue is bad... regarding the EK WB clearances (currently fixed for all sizes)

Regarding the coil whine, I think it exists more or less in all 7970 cards?!

It only got me from 1190 to 1210, but my chip is about as bad as it gets. For reference, It only did about 1075 on stock voltage. I'm doing pretty good to have 1200 24/7.

I didn't have pics of that portion of my bare card or the ek block before I put it on so I slipped a piece of paper in and was able to clear the second cap. This tells me the block isn't riding on that cap so I'm good. Easy test if you're unsure if you're affected.

That's what it's supposed to look like! thumb.gif

The bad one is all blue caps and one red. It's a clear sign the AIB has deviated from spec.
