I put a Trad2 GTX on my 5870, and still cant get 1000 core to work. Ive tried 1.2 and 1.25v, and as soon as I hit 3D it artifacts then freezes and needs a reset.
Witchdoctor was benching it up to 1040 in Vantage. Any ideas whats up? Using a Corsair HX1000, and temps are about 60C in games. The VRMs hit about 75C. They have the small sinks that come with the Trad on them, but its got two 92mm fans blowing through the sink which should cool them enough.

I ran vantage 950core stock volts. Tried 1.2 so far at 980, and display driver stops responding at the end of the second test.

If its the little tiny thing next to the ram that was being cooled by the stock cooler, I put a little sink on it. I had to cut the sink in half to fit, but its on there still.

I guess not having a side case fan sucks lol. The spot on the side panel for one is blocked by my res. I took the panel off and held a fan by the card, and passed at 980 core (990 failed again). Also noticed one of my ram sinks fell off. Was a bitch trying to put a new one on with needle nose pliers and a nife :ohcrap:

if the sinks are falling....you're overheating...same stuff with my modded cards... put a tiny amount of superglue on a corner...its easily removeable.

Is it safe to put glue on the VRM sinks?

I redid the heatsinks with crazy glue, and noticed there was about 1/4 of the GPU with no TIM so I added a touch more TX-3. Now able to run vantage 1015/1300 no problem with 1.26v.

Thats one scary looking rad.
For ramsinks.. I use seiksui thermal tape and after cleaning and applying I hit them with my lighter to give a good bond. (I dont have a heat gun I guess I should get one)

Same thermaltape I put on them. The Thermalright stuff seemed like it was stickier, but would leave more residue on the ram chips. I guess the tape wasnt enough though (didnt heat it or anything).
Hoping to get a some good 3d runs when I get the time. Got 21904 in vantage with 980/1275 and CPU at 4480HT. Thinking 1020/1300 and CPU at 4.5HT should get me around 22.5k.
