Amd Volcanic Islands details

I kept my eye on the forums when Titan was released. Most wouldn't do 1200mhz.



I've owned four 7950s, every one did at least 1200mhz on water. thats a 50% overclock from stock clocks. or a 30% overclock over boost edition.



Lol, ok.

At the beginning when Titan was released the cards clocked between 1126- 1226. But things have improved since then. More recent bios have come out and unlocked alot more potential. In addition, I am starting to see better asics making it into GK110 gaming cards. For a monster chip like gk110, your likely to see the biggest improvements overtime in regards to yields and clocking. Particularly when Nvidia professional lineup is eating the best chips. The most recent gk104's don't really clock better than the old ones, but its seems recently gk110 has gotten better.

Some 7950's are famous for not hitting high clocks. The ones that are know not to do this are a particular model of xfx double d edition which lock the volts and don't use a reference PCB. It is a popular model because of its low price still. I believe there are certain sapphire cards that have limited overclocking potential because of the PCB and voltage locking.

Here is a guide. But with later 7950's. AMD was more restrictive with voltage and alot of newer cards come voltage locked.

1200 on water isn't that impressive for any card this generation. Saying the 7950 is underclocked and saying all them reach 1200 with water isn't that impressive, if this was air I would be more impressed. The base 7950 just doesn't perform that well at completely stock clocks and they need overclocking for sure. I agree that stock 7950's and 7970's are underclocked. But not so much their ghz(1050MHZ) or boost editions(950mhz) which are becoming more and more the norm.


I am talking about the 7970 ghz edition, which I have been using as a baseline as far as performance goes all thread. Some 7970 ghz editions in reviews get like 100mhz out of the cards and that's it.
