Mobo manual says my motherboard has these modes:
Auto, 800MHz, 1066, 1333, 1600, 1866, 2133, 2400.
Should I try setting it to 1600? Can I physically damage my system by setting it wrong? I've been having fairly random system instability and have pretty much replaced everything but my case with no help. I'm hoping it's a memory frequency thing. Guy at a PC repair shop told me that there are more frequency issues with DDR3 than there are with DDR2 (I don't remember the specific way he put it.)
