Have you tried running GPUz while running a stress program? Reason I ask is mine comes up with Perfcap reason VRel nd VOp
Also have you registered your card yet? As it wont let me log in after refistering myself, although I have contacted them about this.
But other than that, seems like a great card, just done a couple of runs on heaven and its nice and quiet in the low 60's![]()
What case do you have them in? How are your temps?

It's such a shame no one has made a water block for this
Lian-Li V2000b.
Temps are really good

See above - use a chip only block. The ram chips aren't cooled by the factory sink anyway.
Ok got the black edition today. Here's some quick feedback.
Build Quality and Temps
-----------------------------
The card feels like its built of quality materials. The cover is metal and everything feels solid and looks stylish.
The overall quality is much better than the Inno3D gtx 970 which I bought previously and returned. The heatsink is pretty amazing and manages to keep the card a very comfortable 64C under load, even when overclocked. In comparison the Inno3D was hitting 80C+ which is pretty poor .
Overclocking
---------------
So far managed to OC it to 1463MHz at stock voltage. 1500MHz works but randomly crashes it so most likely could be stable with more voltage.
Noise
-------
The fans are very quiet. Speed maxes out at about 72% and you cannot hear the fan noise over the case fans which is amazing. By comparison the old vapor-x 7950 was pretty loud when gaming.
Coil Whine
--------------
There is absolutely no coil whine under normal gaming situations.
However there was a lot of whine when I ran the gf OC test (GL4) in MSI Kombuster. The fps in that test hit over 1400fps. It appears that coil whine is present when the fps is higher than 1000 fps. This happened in my 7950 so nothing to worry about. I doubt any game would run at that kind of fps.
Overall I am happy with this card, especially the temperatures. It's a decent upgrade from a 7950.
thanks for this - running a 7950 vapor x also and noticed that it actually is quite noisy when I game (remember buying it and supposedly it was supposed to be on the quite side.
wondering if you can set a profile for a slower (quieter fan) - Im debating about this or the strix ...
This one seems quite nice thou
The vapor-x 7950 temps get to about 73C under load and fan rpm to about 70%. If you reduced the fan speed I guess your temps would go up to maybe 80C. I wouldn't feel comfortable at that kind of temp.
The Asus Strix looks like a nice card but I doubt you would get temps much lower than the Galax EXOC, maybe a couple of degrees. The price difference is the biggest factor between the two.
Arrgh, I've never bought a brand name that I didn't know about before, but at £40 less than the Asus 970 Strix I am really tempted...
What's the warranty/quality like on GALAX? Would you recommend this over the ASUS?
Further update:
The card is performing well so far and temps are staying at 61-64C during gaming (crysis3, Tombraider, etc). This is when it's overclocked to 1475MHz. It appears the voltage maxes out at 1.212V (fixed in bios). I can run the card at 1500MHz but crashes in MSI Kombuster 3.0 in the Furry PQTorus gpu burner test. Temps get to 70C in this test. Works fine in Heaven 4.0 and games though.
It would be interesting to see if the guys getting over 1500MHZ have tested it in Kombuster 3.0. So far that test seems to be stressing the card more than most games.
Another thing to mention is that I had found the image quality to be slightly washed out compared to the Radeon 7950. It turns out that the Nvidia cards set the output to limited RGB by default if they detect a hdmi connected monitor as a tv.
There is no fix from nvidia yet but a user has made a registry hack that fixes the problem and sets it to full RGB. The image quality is much better with the fix.

Haven't seen anyone post a custom BIOS yet for em![]()

Will a cosair rm550 psu be man enough for this card, only powering 2 hard drives and about 4 silent wing fans, 8gig ram?
Assuming no better deal on this come black friday then!?
148W TDP for the card
