@Systemshock2 err SoulsCollective,

Did you try the 18 or 19 multiplier with turbo disabled? Do you know if your ram has samsung hcfo's and what voltage do you have on the ram? These chips seem to like more volts on this board especially 6GB's. My board over reports voltages by .05v so if your adjusting based on what it reads in bios or windows don't. Typically whatever you set in bios is actual voltage when measured. Lastly pull one stick out, run with green slots close to cpu. If she runs then u need to apply more volts to yor ram like 1.710v or so.
