ASUS P5VD2-X m/b

Hi, I have an ASUS P5VD2-X m/b and, according to the user guide, the '2 x 240-pin DIMM sockets support up to 4 GB of DDR2 533 unbuffered non-ECC memory'.

I have inserted 4 GB of such memory in the two slots (2 x 2 GB) but, according to BIOS, there is only 3 GB RAM available for use. Everest reports the same figure, whereas Windows 7 tells me that I have 4 GB!

Could someone tell me how I can use the full 4 GB of memory?

Thanks.

  1. You have to buy a new motherboard. The Via PT890 chipset doesn't support memory remapping. Windows 7 and Vista SP1 report the installed memory, not how much is available for use.
