Don't know the kind of DDR it is supposed to use. Didn't look it up. As it stands now, I removed the SECOND batch of RAM I got from the store. I will have to go to them and return it, explaining the first two sticks of DDR RAM were probably just fine and NOT defective. Seems like I am stuck with 1024 MB worth of RAM until I upgrade everything.

That is the motherboard there. A nice piece of work when it was new. Now... broken, but still working. Current processor is a Athlon Sempron 2600+ (fastest I could afford then).
