Finally, from the basic principle, we know that the 1GB
module will not have dual channel performance. If max
performance is the goal, he wants to buy two identical 1GB

treat 2 512's as one 1GB to dual-channel against the
additiona 1GB, but I find that *extremely* unlikely in a m/b
from Asus or any m/b at this price point (I'd be surprised to
see it in a m/b at any price point).
The manual does say that three modules can operate in
dual-channel mode. ASSuming the manual is correct, what is the
combination that would give dual-channel mode?
I knew B1 always had to be populated and matched with *either*
A1 or A2 for dual-channel mode using 2 slots. But which is the
so called third slot for 3 slot dual-channel mode operation, A1
or A2 (or even B1 for that matter)? ASSuming color coding,
B1/A1 would be matched [B1/A1 are the same color], making A2
the so-called third slot. But we know the color coding rule has
been broken by the B1/A2 combination. ASSuming the so-called
third slot (whichever it is) can indeed still function in
dual-channel mode (it says so in TFM), it would have to be 1Gb.
All the above is still a hell of a lot of ASSuming ! Especially
since TFM doesn't specify anything other than slot B1 has to be
*populated* for dual-channel mode.
There must be something wrong with the logic above if the "be
surprised to see it in a m/b at any price point" is correct
since TFM says dual-channel mode operation can be achieved
using all **3** memory slots. TFM must be wrong. :)
