in my spare time I'm helping people switch from Windows (mostly XP) to Linux. In this case, I'm helping a guy with a quite dated Dell Dimension 5000. The PC is using a single slot with 2GB memory (Samsung m378t5663qz3-cf7). Accoding to the Dell manual this PC supports 400- and 533-MHz DDR2 unbuffered SDRAM, with 256 MB, 512 MB, or 1 GB non-ECC capacity and mounts max 4 GB.
So I wonder that a single module of 2GB (800MHz) actually works!?
I'd recommended this guy to switch to 4 x 1 GB, i.e. upgrading his machine to 4 GB, he saw also the Dell manual, but he said he'd like to try adding another 2 GB of the above Samsung.
Should he do so or stick to the manual recommendations?
