Got my E6600 yesterday and already have my DFI 975XG. This board is still picky with overclocking, setting ram speed to 400 is the only way I can go over 320 fsb, other users are reporting similar issues on certain settings. Ram is Team Group 667mhz. This board won't run 333mhz 1:1 (stock). anyway enough complaining this is what I'm doing so far without even trying. vcore is actually 1.45, there is a droop under load, though I have not experimented with the vcore much at all. On stock voltas I can easily get a 300mhz oc, so more may be possible at stock. http://img225.imageshack.us/my.php?image=stressscreenshotjpgyu3.jpg there seems to be an issue with CPU-Z vcore reporting as ITE shows a different voltage..
