If the GPU is real temp sensitive, water cooling should be a boon. Hopefully we can get some non-vendor water overclock results in from users soon.

Diamond Flavor

Ran heaven X last night

1.25v

1264/1450

2747 .....

Had a few artifacts on the run though.....

Think if you can get 1200 @ 1.2 is the sweet spot

The fan on 100% is completly rediculouse



Mine measures 11 1/8"


But the card it fun to play with for sure

For those stuck at around 1050 on the core, More voltage and less heat is the key to success. (Obvious, but more so for these cards than any other)

Got my temps down by around 10c and put 0.010mV more into the card and now i have gone from 1060 to 1125 and still have not hit any errors yet.

What temps are you getting now after lowering it around 10C? And at what fan speed? I noticed same too... No matter how much voltage I pump into the card, it starts artifacting for me at around 65C.

I'm getting about 60c max in BF3 with my fan speed at around 70% i think.

65c max in Crysis at the same fan speed.

VDDC's getting HOT ? Got to be something to do with a ( somewhat weak, overloaded ) weak vrm I would guess. I have heard that msi and power color are beefing up their vrm's come twin frozer 4 and powercolors new twin fan non-reference. Get 2 reference msi 7970's or wait and see the lightnings....... I don't want to wait anymore ! biggrin.gif

from what i'm reading around the web my XFX BEDD card has terrible VRM cooling. all things consider, i'd get a reference card if i could do it over again. don't think it's worth the hassle and the newegg restocking fee to swap to a new card.

I don't get what artifacting people are having at around 80C? Can anyone post some screenshots, videos or pictures of it? My card runs at 1125 without any other tweaking and I haven't noticed any in Heaven or any games I play so far. I haven't upped the fan speed because as mentioned, anything above 50% is murder on the ears.

If I don't have any problems at 80C, I may have a golden card 8].
