Functional Overview
Mobile Intel 945GM/GME/PM/GMS/GSE, 943/940GML and Intel 945GT Express Chipset
system memory controller supports DDR2 SDRAMs.
For Ultra Mobile 945GU Express Chipset system memory controller functional overview,
see
Three memory channel organizations are supported:
Each channel has a 64-bit data interface and the frequencies supported are 400 MHz,
533 MHz and 667 MHz.
Mobile Intel 945GM/GME/PM/GMS/GSE, 943/940GML and Intel 945GT Express
Chipsets support only one SO-DIMM connector per channel.
When configured as a dual-channel system, each channel can have one or two ranks
populated. So in either case there can be a maximum of 4 ranks (2 double-sided SO-
DIMMs) populated.
