My computer is a eMachines model C2280. The motherboard is an ECS L7VMM2, with a CPU AMD Athlon XP 2200+ 1.80 GHz. I searched this site and the information for the memory is the following:

Two 184-pin DDR DIMMs sockets for 2.5V DDR SDRAM (DDR266/DDR200)
Maximum: 1GB (Unbuffered Memory)/ 2GB (Buffered Memory).

When it says (DDR266/DDR200), do that means that I could use either?

What is the meaning of buffered and unbuffered memory?

Do I need to install the Ram in pairs (like if I want 1 GB I have to put two 512 KB memory sticks, or can I put only one 1 GB stick)?

I also read on another post that most eMachines do not accept high density SDRAM... is it true for this one?

When buying Ram, most of the time they are listed as PCxxxx (example: PC2100). What would be that number for this model?

Any aditional information on memory upgrade for this model is welcome. I know little about computer hardware, so if the explanation are kept simple, I will appreciate it.

I will probably buy the RAM via eBay (I think I find it cheaper there), so I want to know what things to look for and what question to ask the seller. Please, recommend any other websites with good deals on SDRAM that you know of.

If your system will support 1GB modules no need for pairs. According to "E" they do sell a 1GB module for your system but not sure if it's buffered or unbuffered.

I'm not sure what the specs on density for your ram is.

Most ram is backwards compatible but I believe your system came with PC2100 installed.

Thanks for all the info.
Check the following link, I think this one will fit my PC...

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...item=6726706896

but... the voltage in the auction info says 3.3V, but my motherboard says to install 2.5V ones. Is this a crucial matter? Or will the memory still work with the applied voltage?
