DFI Memory Question

[rpbrown]

I am trying to upgrade my system to 4 GB's RAM. I acquired two more sticks of the same memory:

Crucial DDR4000 CL3 BL12864Z503.16TF2Y

All four sticks should be the same. I placed the two new sticks in the yellow slots. However, the computer reports a total RAM of 3326 instead of the 4096like I thought it would. I can see this total on the boot screen and then in Vista.

Is there a setting I should be using in the BIOS - I was under the impression that Vista would see all 4 GB's RAM?

I am running Vista Ultimate and the rest you can see in the signature.

Thanks
