I got them from CDW.com. I normally don’t order from them but newegg didn’t carry this product at the time I ordered it.

DDR2 PC2-6400 CL=6 Unbuffered ECC DDR2-800 1.8V 256Meg x 72
4 Crucial memory - 2 GB - DIMM 240-pin - DDR2 1451518 $25.99 $103.96
I opened my desktop and have this:
4 bays
2 filled with 1GB board each
2 bays open
I removed 1 memory module and noted this description:
DDR2, PC2-6400
Appears I can add either 2 (1GB) boards or 1 (2GB) board to have a total of 4GB.
Correct?
