I have been trying to upgrade the RAM on my Dell PowerEdge 2800 unsuccessfully, likely because I do not know enough about RAM.
The RAM I got a hold of is labeled 2GB 2RX4 PC2-5300P-555-12-xx. When any of these new sticks are installed (in pairs, or singles, in any conceivable combination) I receive a 1-2-3 1-2 beep, and the screen stays black and my machine won't boot.
The RAM that presently works is labeled 1GB 1RX4 PC2-3200R-333-12-xx. After reading online, and talking to my friends, I think the issue is that I was trying to run 555 MHz RAM in this machine.
Honestly though, I have no idea if 5300P and 3200R are actually compatible types of RAM. Are they?
I've been reading about single and dual ranked RAM as well, but I don't think I've progressed far enough to even worry about the ranking yet...
