Hello All,

 Can you mix a 1gb stick of RAM with a 256mb or 512mb stick of RAM in a Dell Dimension 3000?

I recently purchased 2 x 1gb sticks of RAM for my mother-in-laws Dell 2400, but it wouldn't work with 2gb total so I ended up installing a 1gb stick and an original 256mb stick.  The Dell 2400 is running perfectly and recognizes the RAM total correctly as 1.25gb on that machine. 

Anyhow, she wants to give the left over 1gb stick to a close friend who has a Dell Dimension 3000.  The RAM is compatible but the Dell 3000 instructions makes a note about avoiding "if possible" mixing new RAM with old RAM.  Is there really anything to that?  I know on my mother-in-laws Dell 2400 the 1gb stick had to go into the slot closest to the processor, as it wouldn't work when revesed with the 256mb stick but no issue other than that.   

Thanks, Ralph
