4 GB Memory Problem

[efc]

Install and run Belarc Advisor. It will report your memory showing each slot as follows:

1024 Megabytes Installed Memory

Slot 'A0' is Empty
Slot 'A1' has 512 MB
Slot 'A2' has 512 MB

In this way you can see which slot is the problem. First remove and reinstall memory to the bad slot and reboot. If that doesn't work swap suspect memory to another slot and reboot and run Belarc again. There are three possible results.

1. No change - Most likely a bios issue.
2. Different slot reports empty - Bad memory stick, contact your supplier
3. With luck, all slots report memory present.

Ok, i tested each Memory Module in each slot.

Each Slot reports each Module as 1047552. So all slots are ok and all modules are ok.
Belarc screeny attached. (does not show each slot as stated ?)

All 4 modules are in now. But windows Vista 64 and XP64 only show 2.5gb memory. The Bios shows all 4 @ 4193280. Tried with 3 modules, shows 3 gig in bios but still 2.5 in windows.
