I'm having some trouble with my RAM-memory. I have 2 256MB memory-modules plugged into my computer but the BIOS and Windows XP only recognizes a total of 380MB. When I run SiSoftware Sandra it tells me I have one 256MB module and one 128MB. Although I know both of them are 256MB. A few times it has recognized 512MB of memory (for example when I tock them out and put them back in) but then Windows XP crashed into a bluescreen after one reboot and after that it only recognized 380MB again.
The modules are 2 DIMM 256MB (@133Mt/s) plugged into a QDI Kudoz 7 motherboard with an AMD Athlon 1800+ processor.
I would be very gratefull if someone knew how to help me make use of all of my memorycapacity.
