this is good nu's cause it makes buying ram easy peazy
One thing here though, don't think for a minute that any cheap old RAM can be stuck in there and will work perfectly. Many have fallen for this in the PC market and come unstuck. For reliability reasons alone, I'd go for a recognised brand that you'll be able to remember as and when you'll want to add another stick in there. ie stick to Kingston/Crucial or Samsung.
We've got 2 sticks of DDR133/256MB sitting aroud here ATM, as they will not co-exist with the current 256MB currently fitted into my mates ABIT KR7a board. No combination works, it's any one stick alone only :~(
