if you ge 1 DIMM then you still have one free spot so in the future if you wanted to add more RAM you could do so.bran987 said:What is the difference in these 2?
512MB DDR SDRAM 2 Dimms [add $75 or $3/month2]
512MB DDR SDRAM 1 Dimm [add $100 or $3/month2]
If your machine has 2 DIMM slots and you have 2 sticks of ram in, to upgrade your ram you couldn't just add in a new stick, you'd have to replace, so there would be extra cost.
Odds are you will never add more RAM, so 2 DIMMs is fine.
I would reccomend 1G if you can afford it though.
