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?

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

Ok good then you're running at 1333 MHz.

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. You should not get any errors.
