Hi, i see that we have a very similiar rigs , i had OCZ sli ready pc-8500 before and i had problems with them (they were suspending my system when i rate them as 1066-at producents timings and voltages, however they worked fine at lover frequencies), so i stayed with crucial ballistix, now i`m waiting for another 2 sticks from Crucial,what about Kingston HyperX 2GB pc-9600 , our mobo can easly handle this type of memory aswell.
