[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1470

post #14691 of 38701
Good evening gentlemen/ladies alike, I own a 7950 PCS+ and was wondering if anyone had removed the cooler in order to apply better compound. I just started overclocking this baby using Powercolor's Powerup Tuner and let me tell you so far the results are nothing less than impressive. 1100/1325 @ 1.178v I feel that with my temps staying well below 50c in games that I have more room to push. I would like to know what others who have the same card are getting. Thanks.

using 12.8 with a single hd7970 and crysis performance is silky smooth with dx11 textures and everything maxed out

If you can keep temps below 70c you can push for higher voltage and even 1300 Mhz if possible. thumb.gif

So what does the ASIC quality actually mean? I take it higher is better too?

It doesn't mean anything really. It's supposed to show how a card can OC but it's been proven wrong a lot.

Oh okay, how do they get that figure? Kind of like a VID?

It refers to electrical leakage level, lower leakage less voltage loss = more efficiency. That in itself however doesn't mean that particular wafer will overclock well, it just means it does more (achieve X clock) with less voltage (to an extent).

Lower ratings mean higher leakage, which means it's better for watercooling or more extreme forms such as DICE or LN2. It doesn't give you any insight of overclocking the card though. My 65.8% ASIC rating didn't help overclock much over the stock cooler despite load temps being around 45~50C with a waterblock.

Takes me about 1.2~1.225v to get 1125mhz stable. I was hoping to get at least 1175~1200mhz though, but 1200mhz requires the max voltage of 1.3v. frown.gif

Wow that sucks. As you said though, chip lottery.

Yeah I'm disappointed with the max overclocks of my card, but it performs well for Eyefinity and I have yet to face any AMD driver issues in the last 3 years. It just makes me happy that it can do everything I want it to (aside from having 3x DP ports) and it cost me as much as a 7870 as it was used.
