As you can see it has 2 168-pin sockets for PC133 DIMM SDRAM. It says the max memory supported is 512mb.
My question is, why can't I just buy 2 512mb memory units (instead of 2 256mb's)to achieve 1gb of RAM. Do all computers really have a max RAM limit?
To answer the question "Do all computers really have a max RAM limit?", the answer is yes. Every motherboard that you purchase will have a "MAX Limit." It is due to the reason that the BIOS is set up to only ready a select amount of RAM. I would say that when this computer was release that 256mb RAM was one of the largest sticks you could purchase at that time. Now days the new motherboards max out at either 8GB/16GB/32GB.
If you place a 512MB stick of RAM, the motherboard may not be able to read it as it is over capacity for each slot. You are better off to make sure the computer only has 2 256MB sticks, so the computer can run a MAX capacity.
