I have a mach II modded with r507 gas, I have mounted the head and craddle a few times now and I can't get decent temps, I can't get lower than -10 on basic settings with my fx-55. Has anybody had any experiance with the mach II and the SLi DR ? Am I doing something wrong here ? If I put 1.8v cpu and load the system, the temps start to rise and get to 50deg c and teh sysetm shuts off (thats the shutdown temp I set). I;m getting very confused here, any help would be greatly appreciated.
