I'll be honest, i didn't search for this because I'm a bit flustered and confused by my results of scouring the web...

What does the designation "DDR SDRAM" actually mean?
What does the designation "PC2100" (etc.) actually mean?


*EDIT* Okay, so "PC2100" refers to bandwidth, correct? Apparently since the "Dell dude" recommends this for my specific computer, I should stick with PC2100?

Your RAM will run at the speed that your computer motherboard wants it to run at.

That means, as long as you get RAM that's rated AT or ABOVE what your motherboard/processor combo wants, you'll be okay.

DDR (Double Data Rate) SDRAM (Synchronous Dynamic Random Access Memory) is just a type of RAM. Some of the very newest stuff uses DDR-2. The previous generation of RAM was SDR (Single Data Rate). You can't mix and match these. Physically impossible.

Is it important that the "types" match as well (ie PC2100/PC2700)?
 
No. I have both PC3200 RAM and PC2700 RAM in my internet system that runs at PC2100... :)
 
If you can, I would suggest matching the PC# as well. I run PC3200, and just think it makes sense to match everything possible. (IMO)
