Memory
G45
“Hyper-Threading” technology enables the operating system into thinking it’s
hooked up to two processors, allowing two threads to be run in parallel, both on
separate “logical” processors within the same physical processor.
• Supports 36-bit host bus addressing, allowing the CPU to
access the entire 64 GB of the memory address space
• 2 GB/s point-to-point Direct Media Interface (DMI) to ICH10
(1 GB/s each direction)
• Supports 512-Mb, 1-Gb and 2-Gb DDR2 and 512-Mb and 1-
Gb DDR3 technologies for x8 and x16 devices
• One, 16-lane (x16) PCI Express port intended for support-
ing up to two external PCI Express graphics card in bifur-
cated mode, filly compatible to the PCI Express Base Speci-
fication revision 2.0
• An integrated graphics device (IGD) delivering cost com-
petitive 3D, 2D and video capabilities
