The memory controller on the Intel® Q35 Northbridge can support up to 8.0 GB of DDR2
SDRAM. Four DDR2 SDRAM DIMM sockets on the WSB-Q354 are interfaced to the
Intel® Q35 Northbridge memory controller. The DDR2 sockets are shown in Figure 2-5.

CAUTION:
If more than one DDR2 DIMM is being installed in the system, please
purchase two DIMM that have the same capacity and operating
frequency.
Each DIMM socket can support DIMMs with the following specifications:
DDR2 only
Un-buffered only
667 MHz or 800 MHz
2.0 GB maximum capacity per DIMM (8.0 GB supported with four DIMM)
Memory bandwidth:
o
6.4 GBps in single-channel or dual-channel asymmetric mode
o
12.8 GBps in dual-channel interleaved mode assuming DDR2 800MHz
