super fun card to bench, there is no ovp\ocp that I can find running 1.5- 1.7 without a problem. Cold bug is around -50 not -38 my probe slipped out during first few sessions. I can live with -50. Now just gotta find out how sniper got his mems to run so high on cold water.

for coldbug you can also try to give the vrm a constant 3.3v input to keep the vr_enable high all the time. thats the main reason for a cold bug. it will keep running nomatter what cold(theoreticly) but you could run into cold slow, which lowers the clocks etc because of bios and then you need a cold bios.

well, TiN once told me to be sure just put a variable resistor in between. like 50k or something so you can fine tune it and dont directly burn the ic out in case of failure. is just to be safe. but yes if done right it's pretty easy. if bios gets cold in windows and tells vrm to shutdown because he gets wrong temp info, the ic won't because of the 3.3v input the leg is still pulled high and so still enabled.

sata power had indeed 3.3v, much easier. or find a spt on your gfx card. there should be around the first small part of pci-e

Hey Reg, stay away from my 9800's! jk

Snipe's running chilled water sub-z. Your -50c cb is normal...same as mine....better to run these cards on chilled water...not a lot to gain with more extreme methods. Unless of course you want to mod 'em up. Probably not worth the few extra boints either. But go for it! Sniper and I had a little battle last fall on the 9800 gtx's. Maybe we can all battle together
