It was posted here that some boards can operate in dual-channel mode with

three memory modules. Your board is one of the lucky ones. :) They have t
o
be installed in a specific way however.

This is one case where RTFMing is worthless (as far as this board's
dual-channel setup is concerned). You'll still be in the dark. The manual
 I
 looked through
<http://dlsvr03.asus.com/pub/ASUS/mb/socka/nforce2/a7n8x-e/e1876_a7n8x-e_
deluxe.pdf>
[Page 2-8/9] does say that using all three memory slots could still resul
t
in dual-channel mode, BUT it doesn't say specifically what size modules g
o
where or what combination is acceptable.

My WAG would be a 1Gb module needs to be in the third slot. Which slot wo
uld
be considered the third slot is a WAG. :)
