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.

My guess is atleast one of them is defective and needs to be replaced.
Try running just one of the modules and see if you can figure out which one it is.

Get Memtest86 <A HREF="http://www.memtest86.com" target="_new">here</A> and follow the directions for running the tests. My guess is that you have a defective RAM module.

Spec:
Intel P4 2.4B
MSI 645E Max-U Mobo
1GB DDR333
R9600XT 128MB
SB Live 5.1
WD 60GB
Maxtor 120GB
LG DVD+-R/RW
WIN2K PRO SP4
