Intel x48 Board Corsair memory not at 1600


Recommended Posts

Hello everyone. I am trying to boot my PC at 1600 ddr3. I have a 2x2 gig 4 gigs total memory set. Now it won't boot at 1600 even though i bought DDR3 1600. It down clocks to 1066.


I have tried entering the timings and voltage with no go. If anyone on here could enter in some detail how to adjust everything in the memory I would appreciate it. Also does my cpu speed need to be higher? It's currently at 3.16ghz.


Thanks to anyone who can help.


My rig details should be above in this post.

Boot to the Memtest CD and allow for two full passes. Then, if stable, enter Windows and run CPU-z. Post screenshots of CPU-z's CPU, Memory and SPD tabs.
