Integrated video and dual channel memory

[hunter33]

When you allocate memory to integrated video, is it all taken from one stick or equally from both? I've noticed that the memory in PCs with integrated video is not running in dual channel mode.

I am also interested in this.

Yesterday I checked a PC at work running a socket AM2 MSI K9AGM with integrated Radeon Express 1250 video. It has 2gb of Wintec Amp-X memory, 256mb allocated to video, and is not running in dual channel mode. Newest BIOS revision and I don't have any explanation as to why the memory is not in dual channel mode. Last night I checked my wife's PC which has a socket AM2 Foxconn A690GM2 motherboard. It has 2gb of Transcend Axe memory, 256mb is allocated to the integrated Radeon Xpress 1250, and the memory *is* running in dual channel mode despite some being allocated to onboard video.

I guess nobody knows the answer to this question. Either that or it's of no interest since it's not related to gaming

At work every configuration has DUAL CHANNEL with integrated graphic. But they are all INTEL chipsets with CORE 2 DUOs. Could it be a chipset matter?
