6950 TF III Can't Stabilize Past 900MHz - Page 2

post #11 of 24
One of my lightning which i was selling did 980 Core with 1.2V and the other did 990 Core with 1.2V. I didn't play with the mem tho. I ran them 100% load for a day without any issues.

Edited: NVM my post, somehow i thought you were talking about the 6970 smile.gif.

Im not sure if i got lucky with my own card or not, but i haven't had to up the volts so far for mine, im at 900/1400, could of even went higher but i saw no reason for the extra heat as it plays games fine as it is.

You should try sapphire trixx, you can use it whilst using CCC for 20% pwr control.

Honestly, if you don't NEED that card for a few days, I would return it and get a different one. There's almost no point in a card with that epic of cooling that can't OC as well as a reference card. Unless your only goal is silence.

Well the new AB has an AUX voltage control which is like the Power Control in CCC.

Also, I have two cards, so I would try to return this one, but it was acquired via trade.

Ok, so I seem to be hitting a voltage wall at 1.2volts. I know that shouldn't happen, so I think I am overlooking something. Any ideas?

Settings: (RAM is at 1300 throughout tests)
850MHz @ 1.11VCore + 0% AUX = Yes (Stock)
900MHz @ 1.2VCore + 10% AUX = Yes
915MHz @ 1.215VCore + 10% AUX = No
925MHz @ 1.25VCore + 10% AUX = No
