Hello,
what is the optimal RAM to pair with a Q8300 CPU - 800-1066 or 1333 - not really an extreme gaming system, just for best overall performance/stability ... right now my friends system has 800 and he's having a lot of lockup & reboot issues
What motherboard is he working with?
It really shouldn't matter all that much running with 667/800/1066.
How much installed RAM is he working with?
Sometimes adding a small bump in the RAM voltage will help things stablize.
