Looks like under Ai Tweaker.

Sorry I wasn't clear, I am familiar with the AI tweaker, which setting is wrong?

btw I am running the DRAM Bus Voltage at 1.66V per this link http:/www.clunk.org.uk/forums/overclocking/22106-core-17-overclocking-guide-begginers.html

[QUOTE=sdbardwick;239947]Really need to run memtest.
Memory manufacturers make their modules to run at a specific combination of speed and voltage. Your RAM might run fine at lower speeds at lower voltages, (like 1333MHz on 1.5V) but to run at 1600MHz it will need the correct voltage for that speed (in this case 1.65V). Intel advised that 1.65V is the max you should use on i7 processors (more and you could damage the memory controller).

The BIOS can incorrectly select a voltage that is too low for the configured speed; that leads to memory errors.[/QUOTE]


Okay, ran Memtest for 10+ hours, no errors.
