hi all here is my system specs

asus m3a32-mvp deluxe wifi
kingston 2x2gb hyperX 1066 mhz ram which is '' KHX8500D2K2/4G ''
amd phenom 2 720 BE

im running cpu at 3.6 ( 18x200 with Vcore 1.5 )
but i cant get ram working at 1066 mhz i tried to rise up voltage to 2.3v which has written on the box and rising the ram frequency to 1066 mhz at bios

when i looked at cpu-z , everest and amd overdrive ram shows (800) 400mhz

what am i doing wrong at some others forums people are running the same ram at 1066 with 2.1v only
