Heya...

I have the same problem..I am running a Corsair Dominator (1066) in my PE45-UD3P....All the tools that I have tried says its running at 533...Any ideas?
 
^^If in CPU-Z its showing 400 Mhz it means it running at 800 Mhz (DDR - double-data-rate )....

533 Mhz might mean its running at 1066 Mhz

@sudan
Since yours is PC6400 800 it should run at 800 Mhz.... 400 Mhz X 2
 
Check the timings of both the rams, most probaly they have different timings.

Make sure that both sticks have same timings in the BIOS.

^Can we enable different timings for matched sticks installed as a pair? :S

Mostly yes, it takes the timings on the slower module to run both though. This also runs into a problem with certain boards.

run everest and in tools click cache and memory benchmark, it should score around 7-8k MB/sec read / write if working at 1066mhz.
