How do you know it only tops out at "like 660 mhz"? If you're reading that from CPU-Z you have to double it, it's actually running at 1333 MHz.

What motherboard and CPU do you have? Also provide a link to your RAM.

Download CPU-Z, run it, and check the memory tab. What does it say on the Memory tab next to DRAM Frequency? http://www.cpuid.com/cpuz.php

By the way your memory runs at the same speed regardless of whether your CPU is under a full load or at idle.

Where do you see it reporting that?

You'll have to change the DRAM Frequency in BIOS to run your RAM at 1600.

Ok i went into bios i set the frequency to 1600, which put my timings at 9-11-11-29 so went ahead and manually changed timings back to 9-9-9-24, is this how it should be for my ram? just want to make sure and not burn up ram or anything lol

Yes, that's right. Also set the V to 1.5V. Then download memtest86+, burn the ISO to a CD/DVD as a bootable disc, restart booting into the program and let it run overnight. http://www.memtest.org/ You should not get any errors.
