Building my brothers pc

Hi all, I have a bit of a dillema with a pc im building for my brother. Ive bought a new motherboard and processor for him but just need to buy some ram and its finished. His motherbord can support drr400 (pc3200) but my mate is also offering 1536 megs worth of pc2100 for about £50 which seems to be a bargain, so what should I do? Go for the 1536meg slow and cheap ram or buy some brand new 1gig ddr 400 ram which is fast but expensive and also isnt as much in terms of the amount of memory. Ive just bouoght him an intel motherbaord for £60 and have bought him a 3.2ghz p4 for about £150 so saving some money on my mates ram wouldnt be so bad, But do u think that ram is too slow, especially when put with this fast processor. Well thanks for your help!
All the best Phill.

A one giga DDR 400MHz considered quite good, don't under estimate the speed vs memory, I would go for the 1 giga 400Mhz.

I have 512 mb ram, but their frequency is 400MHz therefore I don't seem to have any lose in performance nor need in even more memory (although an extra 512 would be great )

Pc2100 is 333 MHz? (Correct me if I'm wrong) I would leave that alone and as I said, go for the one giga 400 MHz. :thumbup:

If your brother doesn't mind performance...get the 333Mhz cheap (used ... I guess) memory.

1Gb DDR400 every time. If the board supports it, you will be able to run the ram in dual channel which is great :thumbup:

thanks, I think ill buy him the ddr400 dual channel.
Thanks for your help!

nahhh go with sdram much better than ddr 400 B)

get some PC4000 ram its primo! ;)

a 1 gig dual channel kit is the way to go.

Just don't buy the pc2100 sticks, because that's only 266MHz (pc2700 = 333) and that's way too slow nowadays.
