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 ...

Memory geometry describes the logical configuration of a RAM module, but consumers will always find it easiest to grasp the physical configuration. Much of the confusion surrounding memory geometry occurs when the physical configuration obfuscates the logical configuration. The first defining feature of RAM is form factor.
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.
There is only a little difference between a dual rank UDIMM and two single-rank UDIMMs in the same memory channel, other than that the DRAMs reside on different PCBs. The electrical connections between the memory controller and the DRAMs are almost identical (with the possible exception of which chip selects go to which ranks).
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The static qualifier differentiates SRAM from dynamic random-access memory (DRAM):

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 ...
