2.5.2 Memory Controller
The IMBA-XQ354 has four DDR2 DIMM sockets interfaced to the memory controller on
the Intel® Q35Intel® Q35 Northbridge. Each DIMM socket can support a 2.0 GB (max.)
667 MHz or 800 MHz DDR2 SDRAM DIMM module with a system maximum of 8.0 GB.
NOTE:
For best performance, each memory module should 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
 8.0 GB maximum capacity (2.0 GB maximum per DIMM)
 Memory bandwidth:
o 6.4 GB/s in single-channel or dual-channel asymmetric mode
o 12.8 GB/s in dual-channel interleaved mode assuming DDR2 800 MHz
2.5.3 PCIe x16 Interface
The Intel® Q35Intel® Q35 PCIe bus is compliant with the PCI Express 1.1a Specifications
has the following PCIe lanes:
 One PCIe x16 graphics interface
 PCIe frequency of 1.25 GHz (2.5 Gb/s in each direction)
2.5.4 Graphics and Display Features
The Intel® Q35Intel® Q35 GMCH integrated graphics device (IGD) has 3D, 2D and video
capabilities. The Unified Memory Architecture (UMA) uses up to 256 MB of Dynamic Video
Memory Technology (DVMT) for graphics memory. External graphics accelerators on the
PCIe graphics (PEG) port are supported but cannot work simultaneously with the IGD.
