Re: GA-8I945P-G 4GB Ram Problem

This is what it may be. The Mobo has 4 DIMM slots and supports Dual-Channel Memory on a 32-bit platform. Due to Standard PC Architecture, a certain amount of memory is reservred for system usage and therefor the actual memory size is less than the stated amount. For example, 4GB of memory size will instead be shown as 3.XXGB memory during system startup. Also make sure you update your BIOS.

GA-8KNXP 4 X 1 GB Ram Bios shows 3.500 GB

This is because you are running 32 bit system. 32 bit system can only use up to 4GB RAM theoritically but some only 3.5 GB RAM.
Only 64 bit systems can use 4GB RAM and more.

Can Gigabyte GA-8I945PLGE-RH supports 4gb ram?

Sorry, but at the moment you can't do that. This is because the BIOS is programmed to manage only 2GB memory. I searched for BIOS upgrade to resolve the memory issue but with no luck. At the moment your motherboard supports only 2 GB RAM.

ASUS P5VD2-MX SE recognizes only up to 2500MB RAM


Actually you are doing better than you think, According to your MB specs it is only supposed to hold a max of 2GB (1GB per slot). The updated BIOS may be allowing for the additional 500MB.

If you would like to verify, here is a link to the manual for your MB:
