First of all I have to say thanks. I read almost all this thread, and with all your help I was able to do the GPU mod.
I didn't use the soldering iron, because I don't want to loose the warranty, I made the mod using Bison Electro . It was easy, so easy that after I made it first time, I clean it down in one hour, because I suspected the card was damaged. I couldn’t get 3dmark to run even at stock. It was because of CPU oc, I loaded some unstable bios setting, while I wanted to test the card
Last week I installed Maze 5 wb, and the temps max at 45 with 1.3 under load. In the process I wanted to make sure the ram heatsinks will not fall off, and I added some AS thermal adhesive on the memory (uncutted).
Now my problem is that before the WB, using zalman cu900, and the same heatsinks (sticked just with thermal paste), I was able to run the card mem at 1950mhz. Now it's not stable at stock (1900), it only works at 1850 (with stock everything). The GPU hits 850 easy, but with the mem at 1850 I'm doomed. I don't plan to stress the Hynix memory too much but I expect 1950.
I must add that I tried everything to cool down the heatsinks, and the only conclusion is that the AS adhesive, is somehow not doing its job on one heatsink or maybe multiple ones. Or am I just missing something else?
Unfortunately the only solution is to take them down and stick them again with cutted AS adhesive, but as I read this is very hard (freezer) and risky.
Maybe I’m wrong, but I don't think there is another explanation. I just posted to tell my story, and maybe some advices.
