Sapphire HD7950 3GB Vapor-X Review

[Ket]

Thats a real shame about your card Sonda, I'm still looking at fixing this broken POS when I have time. One thing I can say for certain is even after all the VRM cooling mods I've done (got them down to a max of around 90c @ 1150 / 1600 1.056v (actual), 1.6v memory running unigine valley maxed) is that these VRMs do not like any kind of voltage at all. Even with a paltry 1.056v (0.98v under extreme load without me compensating for vdroop) the VRMs still hit 80c+, that kind of temp for voltage that low and horrible vdroop is just a joke. I could throw almost 1.2v at my 7950 TwinFrozr with its stock cooler with the same GPU speed and faster memory speed and the VRMs wouldn't get hotter than about 83c. If I had gone to the lengths with that card as I have with this Vapor-X I doubt the VRMs would get much hotter than 70c or so.

Not sure what to do with this card, on one hand by keeping it I'll continue to push forward trying to make a nice vBIOS editor, on the other hand I'm sick to death of this Vapor-X and just want to swap it for a GTX670 or something. Hell, at this point I'd even consider swapping it for a excellent clocking HD6970 as far as I recall those cards didn't suffer horrid VRM temps once decent VRM heatsinks were fitted.
