up to 2F90 (up to 75% quality) - 1.1750V

up to 34D0 (up to 80% quality) - 1.1125V

up to 3820 (up to 85% quality) - 1.0500V
up to 3A90 (up to 90% quality) - 1.0250V

Negative..... He means the 1049mv.
He has a 85% chip. which is awesome !!!!!

If I keep these ones I'm probably not going to put them under water because it seems pointless.

1050 is a good overclock. But if you want to go extreme and water, then go change them.
I'm settling for 1085/1575 24/7, but thats just me.

My card is suppose 2 be a 1.1750V card, but I managed atleast 1150/1500 (havent testet more, just went straight 1200/1525 after that) so ye. Idk what do think really

What happen to being able to set these cards no problem to 1125mhz on CCC? All these different vid's seem to be a giant mess. Some getting 1200 others not being able to break 1100. I'm glad I didn't pull the trigger on two reference cards. Its a crap shoot man. I honestly think I'm going to wait and pair a 7990 with a 7970 for trifire both with mild overclocks. Trying to push these cards at this point just seems like a giant headache.

Maybe you're expecting a bit too much. 200+mhz overclock (especially when talking about 1100-1200mhz core range) is nothing to sneeze at. The "vid mess" is not scientific and doesn't prove anything as of yet, so don't even worry about it. Amd never advertised that all of these would overclock into the 1200 range.

i was able to get mine to 1175 on stock volts but havent been able to get up to 1200 (tried using 1.85v but i was getting artifacting then the driver crashed).

What is the best driver to use right now? currently im using the 11.12 support drivers to avoid any issues but Ive seen people getting better fps with the newer 12.1 drivers.

I'm just saying before and after its release there were quite a few reviews showing how to do a simple oc through CCC moving the slider to 1125mhz and powertune to 20% and it was said to be safe and stable. This is all I would have done with these cards. Its simple and safe and done through AMD's own control panel. I can see those who plan to throw water on these using afterburner and other software to volt these cards and push the clocks but those on air not being able to even achieve 1125 from 925 stock clock seems like a problem to me. Sure the gains aren't huge at 1125 but there is still improvement and something for those that don't plan to water cool to be excited about. The fact that there are a decently sized group of 7970's that can't even reach 1125 without crashing and being stable is a major fail for amd imo. Have those who haven't been able to break 1050+ tried disabling afterburner and tried to clock with amd CCC?

Ok i just did the /rr174 string and it shows me "3750". My card was drooping down to 1.098v under load @ 1125
This means i have a good card right?
