I have two slots for DDR ram. I've got one stick of 256 megs but want to get some more. I didn't pay attention the first time I bought my stick of ram so I don't know the specs of it other than the capacity. So basically, I'm looking at www.PriceWatch.com and I don't know the difference, or if it matters, in the types of DDR ram.
PC 3200
PC 2700
PC 2100
Does it matter which kind I get?
