RAM speed not being recognized

I've just installed newer ram into my computer. The RAM is Corsair XMS2 Dominator DDR2 1066. MB is Asus M3A. Problem is that the computer only recognizes the RAM as 800MHz not 1066. Any help would be appreciated

YOU porbably just have to go into the bios and manually adjust the ram speed. some ram does not come with the epp profile that the board can detect its speed.

I'm had to go into the BIOS to get my RAM to run at 1066. Manually put in the correct RAM timings and make sure the adjust the voltage as well. Some motherboards also need a little bump to the northbridge voltage (MCH) if you are trying to run 2x2gb at 1066.

thanks. I'll dig into the bios and try to figure it out.

@ e.clay. Thanks for the voltage hint. I'm running 4x1GB

You didn't post a lot of details but according to Asus DDR2 1066 is supported only on AM2+ processors which probably means newer Athlon x2s and Phenoms. But, you can always manually force it in the BIOS. Make sure you're running the latest BIOS as well

@ anduril

You are correct on both counts; I didn't start with enough info and Asus boards will support 1066 RAM only with specific family of CPUs. I am running a Phenom x3 710 in this computer. I still haven't had the opportunity to dig into the bios yet.
