Dude DC2+OPEN BOX= DIASASTER

Some1 returned that card before more than likely VRMs gets too hot or something is wrong with it. There were alot of dc2s overheating and i believe they have made a revised version. Hopefully its ok but i would stay away from that.

Just curious because I've got a spare H50 just sitting here, thought it might be fun to try it out on my 7970.

Like this : http://www.ekwaterblocks.com/shop/ek-vga-supreme-hf-hd7970-cu-adapter.html

Is this bracket compatible with the AMD 7950/7970?

I've searched but couldn't find any examples of the 7950/7970 with this bracket. I think I've read that it is compatible.

However, I actually can't find anyone that has put the kuhler 620 on these cards...

i think its worth trying because my overclocks would fail when playing bf3 using driver 12.4... now using 12.6 fix my issues my overclocks now seem stable so i would give it go thumb.gif

I didn't understand Why Amd want to release a 7970 at just 1000 MHz when every 7970 Can reach the end of CCC 1125 easily

Got some more numbers on those Sapphire 950Mhz Editon 7950s. So far I'm only looking for something that will run 24/7 without errors on the stock voltage. I was able to get a 3DMark score of 14695 running at 1100/1325, but I there were artifacts in the last two tests and a bit of tearing early on.

338

I dialed it back to 1075/1300, everything was a smooth as butter, and they pulled a 14482. BTW, neither 1100/1300 or 1075/1325 was able to run without artifacts/ tearing.

338

I might be able to get like 1090/1315 or something, but I didn't have time today to do so much fine tuning. One thing I noticed was that increasing the memory clocks increased heat far more than increasing the GPU clocks. This may be an indicator of Sapphire's steel plate memory cooling being insufficient for serious overclocks. More to come when it cools off this evening.

I would think that it is to enhance the reputation of the 7970 when people compare it to the 680 and constantly call it inferior. I've said it before, AMD has SIGNIFICANTLY underclocked the 7900 series cards. When, as you say, almost EVERY 7970 can hit 1125Mhz right out of the gate, on stock fan profiles, it is obvious. It would be different if 10% of cards were hitting these clocks, but I am yet to hear anyone that cannot hit at least 200Mhz above stock on either the 50 or the 70 variant of cards.

When 7900 series cards are at their full potential (1000Mhz +) they compare very favourably to their Nvidia counterparts. I think AMD realizes this, and is trying to get a little credibility back, which I do not feel they really every lost. Whether or not Nvidia have another chip up their sleeve is irrelevant for now. It isn't released and priced and therefore cannot be compared.

I could be wrong, but there is no denying the potential for these cards, as everyone here knows or is finding out as they purchase them. I am not sure the same headroom can be found on the 600 series for team green, but when you combine raw clock speed and gaming performance, with Eyefinity support, 3GB of VRAM (future proof sort of) the compute functions of the card to enhance non-gaming tasks you really start to have a winning combination.

I want to get the reference powercolor HD 7950 because it is $340 after MIR, which is ridiculous pricing. Anyone have any experience with the reference cooler - is it good enough?

You need to clean install windows than. 12.6 works perfect after a clean install (I just dis this) so I advise to go that routw
