Architecture

200- and 266-megahertz (MHz) double-data rate (DDR) synchronous dynamic random-access memory (SDRAM)

Dual in-line memory module (DIMM) sockets

two non-error checking and correction (non-ECC)

DIMM capacities

128, 256, 512 MB, and 1 GB

Minimum random-access memory (RAM)

128 MB

Maximum RAM

2 GB

Basic input/output system (BIOS) address

I have found out which one to buy but if I wasn't told, how would I figure it out from the information above?

 

Thanks in advance.

Oh, i forgot. the system is: Optiplex 170L: Intel Pen4 3.0GHz/800MHz, Intel 865 chipset.

I heard that there are some kind of PC3200: PC3200 DDR333, PC3200 DDR400, ...

Is that right? What does this mean?

When all else fails Reading the Manual never hurts.:smileysurprised:
