Is this RAM 1.65v? I just built an i7 rig with the same issue using 1.65v RAM it defaulted the RAM to 1.55v at 1066 MHz...I had to replace my RAM modules with 1600 @ 1.5v RAM sticks..This fixed my issue...Intel chips are super picky about RAM
Yeah, it needs 1.65 volts to run at 1600... What do I do? Do I have to replace the RAM? I tried tweaking the voltages to my advantage, but that didn't work.
