Dual-channel memory slots, color-coded orange and yellow for this particular motherboard. Dual-channel-enabled memory controllers in a PC system architecture use two 64-bit data channels. Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of ...
Like its predecessor, socket G1 systems, it can only run in dual-channel memory mode, but with data rates up to 1600 MHz (as opposed to the triple-channel mode which is unique to the LGA-1366 platform and subsequent Xeon sockets). Socket G2 CPUs are also known as FCPGA988 socket processors, which should be pin compatible with PPGA988. [2]
In a dual-channel mode configuration, this is effectively a 128-bit width. Thus, the memory configuration in the example can be simplified as: two DDR2-800 modules running in dual-channel mode. Two memory interfaces per module is a common configuration for PC system memory, but single-channel configurations are common in older, low-end, or low ...
Moreover, if a mainboard has a dual-or quad-channel memory subsystem, all of the memory channels must be upgraded simultaneously. 16-bit modules provide one channel of memory, while 32-bit modules provide two channels. Therefore, a dual-channel mainboard accepting 16-bit modules must have RIMMs added or removed in pairs.
The memory controller provides a dual-channel memory mode. The board has two DDR2-800 memory slots, which enables up to 16 GB of RAM memory (using ECC modules). It also supports expansion boards using PCI Express x16 bus.
Socket G1 systems can only run in dual-channel memory mode, compared to the triple-channel mode of LGA 1366, as a result of the lower pin count. See also [ edit ]

A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
