I installed 4x4 ddr3 1600mhz ram but my cpuz reads it at 686.9mhz. My bios reads it at 1033(or something similar to that number.)

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

thats the ram I have. I bought 2 of those packages and installed the ones that came in the same package right next to each other.

So I installed the first pack into A1/A2 and the 2nd pack into B1/B2.

Anyone know why this is happening or what I can do to get it running at 1600mhz?

Hi, By default, the RAMs run according to the SPD (1333 MHz in your case). For 1600, on Intel boards you'll have to set the Ai Overclock Tuner to XMP.

And DDR means double data ram: 687*2=1374 . That's what cpu-z displays.
