Corsair XMS2 Ram

The Tech Wizard
I bought the twin gig Corsair XMS2 Ram 800MHz.
In diagnostic it says ( 5-5-5-18 @ 400MHz / 4-4-4-13 @ 270 MHz )

I was thiking that it was suppose to 4-4-4-12 @ 800MHz when I bought the pair.

Is there a way in Bios to get it up to where it should be?

Each stick of RAM has what's called an SPD, which stores all of the timings and frequencies, such as 5-5-5-18, 400MHz. The reason for the 'underclock' is so that it will be sure to boot in ALL systems. Some motherboards may not like 4-4-4 timings, for example, which would leave you with a non-bootable system.

You can go into your BIOS and set everything manually though:

CL (Cas Latency) - 4
tRCD - 4
tRP - 4
tRAS - 12

Also make sure your computer has 400MHz for the RAM selected, although I'm quite sure it will be default, especially if you are using an 800FSB or 1066FSB processor. Make sure you choose the correct RAM voltage as well. At those speeds, I assume 1.9v would be more than enough.
