Paul,
What type of DDR2 RAM were you after ? PC2-3200 ? what size memory per
stick of ram ?
I have one stick of VS512MB400, one is 512 of PC2-3200
http://www.corsair.com/en-au/vs512mb400, and another stick of similar
type.
I have two VS1GB667D2 (i.e. Matched, 1GB DDR2 Memory, 667MHz)

Hi all,
I'm trying to get my partner's computer running a bit more smoothly,
and it
needs more RAM, specifically DDR2 SDRAM. I'd like up to 8GB of it,
if any of
you hoarders - er, tech parts collectors - would have some spare that
you'd
like to sell. I can buy it easily enough on eBay but thought I'd
email the
list first to pick up something sooner.
Thanks in advance,
Paul
