Does a JEDEC conform 6 layer DDR (f.e. DDR433, DDR400, DDR333) memory module
and SPD Ram need to meet any additional requirements in order to work in
Dual Channel mode with nVidia nForce2 Ultra400 or Intel Canterwood 865PE/G
and 875P chipsets?

Or can any module specified as DDRxyz be expected to work in Dual Channel
mode as well?
