Hi guys.
If I get this mobo, can I use the DDR RAM I already have now and then stick some DDR2 RAM in it later and use them both at the same time???
Cheers, Garry.

Probably but unless you tell us the mobo, we can't be sure!

This review says the RAM types cannot be mixed.

DieSse - it seems to be a hit and miss process these times; I am mixing 512 MB 2100 and 256mb 2700 RAM at the moment with no obvious problems. I think newer boards seem less tolerant.

"...newer boards seem less tolerant"

As timings get faster, yes they probably are less tolerant. Also Dual Channel working is extremely crtical as the accesses to each RAM module are interleaved, leaving even less room for error.

The worst thing about mixing RAM speeds and manufacturers is that it's more likely to lead to occasional problems, than not work at all.

However this question is about mixing DDR and DDR2, which is a different kettle of fish anyway.
