In the days of the 1 gig plus CPU, this is pretty small stuff but was made an offer on a 766 that was too good to turn down. It runs without a hitch at a FSB of 75 (default values) and will not post at 100 (no suprise). At 83 (default values), it goes thru all the motions (postd, DMI, etc.) but hangs just before windows comes up. Would a boost in voltage be the answer? Any suggestions greatly appreciated. Running on BH6 motherboard, SS version bios, Asus S370-DL CPU card set at default. Would be nice to go from 863 to 955 without too dramatic a voltage change. Thanks for any help.
