Having purchased a P7P55D-E PRO board, I've gone and got me 6GB as 2GBx3 chips to use w/W7-64. But I'm now confused as the manual there does not mention anything about a 3 chip configuration.
Hence the question, does the P55 chipset used on this motherboard support/recognize 6GB installed as 2GB x 3 chips?
According to the Intel diagram it only supports dual channel memory.
It may run on that configuration but may not be optimal since one memory module would not be running in dual channel mode. The Asus owners manual does not show using 3 modules, only 1 (single channel mode), 2, or 4 in dual channel mode.
Use the download tab and choose the OS then download the user manual.

You'd be better off to go with 8GB - 2x4GB.
