I am getting a Dell PowerEdge 840 server and they offer single and dual ranked ram and this is sometihing new to me.
I saw this question:
but that doesn't seem to answer - which one do I want?
back in the day, I think the thinking was - better to get more RAM on a single stick, to leave room for more sticks later?
(if you needed 512 MB, you might likely opt for 1 stick of 512 rather than 2 of 256... because older machines only had 2 or 3 slots?
But then there was DDR2, which, other than a single stick, you had to put ram in there in pairs? so would 2 -256s be better than 1 - 512 then? there would be performance issues, but you were still eating up slots faster 1 way rather than the other....
But now for the server:
you can get:
1GB DDR2,533MHz,2x512MB Single Ranked DIMMs add $0
1GB DDR2,533MHz, 1x1GB Dual Ranked DIMMs [Included in Price]
Which do I want? for Performance reasons? For expandability reasons? WOuld the answer differ if this was for sbs 2K3 standard or win xp pro?
