hELLO ALL, Just installed 4x1 ocz nvidia sli pc8500 and system would not boot not even into bios. Removed 2 x1 and no problem booting. Any ideas ? Replaced 4x1 OCZ Reaper 4x1 PC6400 4-4-4-12 (824mhz) which worked fine but figured I would try the 8500 out. I'm sure I had set the v to +4 Now I have the system oC'ed but before install I went back to stock settings.
