-Power Supply: Asus 550W/500W

First without any overclocking i couldn't get my ram to work at 1066 :S
i took the ram timings from the official website which came out to be 5-5-5-18 with 1.8v , and 5-5-5-15 2.25V but i could never boot with it.

i searched the forum and tried this template ( A ) but still i couldn't boot, nothing comes on screen and then bios reloads the old settings and reboot.

1)Please Advice, how can i run my ram on 1066MHZ ?
2)If you have any over clocking advice please mention it, i dont know how far can i go with this system.

Note: I have found this ram table http://i250.photobucket.com/albums/gg264/pyongmu/STRAPSDIVIDERS.jpg?t=1233275713 dont know if it can be useful

yes disable the Dram performance enhance or take it down to standard. bump your dram voltage to 2.2. now start messing with the (G)MCH Frequency Latch and System Memory Multiplier. when you load CPUZ make sure it is not a 3:5 divider as it is a bugged divider and is slow.
