Memory: Does it matter if big DDRs are firsr or second?

Memory: Does it matter if big DDRs are firsr or second?

Posted to alt.comp.hardware and alt.sys.pc-clone.dell, since the
computer is a Dell and I started the topic in that group, but have
broader questions now.


I have two 512M and two 1G DDR[1]s and they are the same speed PC2700,
the same 333, the same CL 2.5, the same non-ECC and assume everything
else the same except the brand and size.

Does it make a difference if the big pair goes in the first pair of
slots, or if the small pair does???

Is this true for DDR2 and DDR3 also?
