[damien c]

ok guys i have recently bought a new mobo asus formula striker 2 and when, i changed to quad core i also got some new ram. the ram is 4gb ocz reaper 800mhz, http://www.overclockers.co.uk/showpr...odid=MY-096-OC when i first turn the pc on and you get the post screen it says sli ram detected, so i go in to the bios and it gives a couple of options for it:
cpuoc 0% up to 20% i think
cpuoc max
expert mode

now i have tried the ram on all settings and it just crashes my pc as soon as i get in to windows.
my timings are 4-4-4-15-2t at 2.2v which is what ocz says it runs at, question is has anyone got any ideas why my pc crashes when using these options. i have my cpu (q6600) oc'd to 3.0ghz and that is now stable after allot of voltage changes and also does sli ram make any difference for games.
all help greatly appreciated
