to follow on from this I've not had much experience of Triple channel memory as yet, not sure which would give the best performance
3 x 1GB in matched bank plus 1GB in another bank or just the 3 x 1GB in the matched bank alone.
would be interesting to see some actual results :)
Have not used it myself, but it seems reasonable that a fourth stick would cause it to run at 1x or 2x rather than 3x.
Seems a reasonable assumption
If adding the extra stick reduces performance it is a retrograde step - unless the fact that the extra stick is available prevents the use of virtual memory, which may make the whole system worse off.
probably easier to just say always install in threes
You can't run triple channel with a C2Q. The amount of Ram is 4GB which is correct.
This is dual channel.

First of all, the OP has a Core2Quad CPU, which means Intel LGA 775 socket architecture, which in turn means dual-channel memory controller.
I couldnt find his mobo on Asus site to see exactly which chipset it has, but P35 Intel chipset has the support for DDR3 memory.
DDR3 does not mean it automatically has to be used in 3,6, 12 GB, not in LGA 775 socket architecture anyway.
DDR3 means something else :
DDR3 SDRAM - Wikipedia, the free encyclopedia
AnandTech: DDR3 vs. DDR2
DDR3 triple-channel memory controller was introduced with Intel LGA 1366 socket
( Core i7 processor 920/950/975, and X58 chipset).
In this architecture, you put memory in 3s
( either 3, 6, or 12 GB ).
However, this fall, Intel will introduce Core i5 and Core i7 processors for LGA 1156 socket, and P55 chipset, which will have again dual channel memory controller, which means you will need to put memory in pairs.
