    en.wikipedia.org/wiki/Multi-channel_memory...

    AMD processors for the C32 platform and Intel processors for the LGA 1155 platform (e.g. Intel Z68) use dual-channel DDR3 memory instead. The architecture can be used only when all four memory modules (or a multiple of four) are identical in capacity and speed, and are placed in quad-channel slots. When two memory modules are installed, the ...

    en.wikipedia.org/wiki/Quad-channel_architecture

    Quad-channel computer memory is a memory bus technology used by AMD Socket G34 released in May 2010, with Opteron 6100-series "Magny-Cours" (45 nm) [1] and later by the Intel X79 chipset released in November 2011, for LGA2011-based Core i7 CPUs utilizing the Sandy Bridge microarchitecture.

    en.wikipedia.org/wiki/DDR3_SDRAM

    Compared to DDR2 memory, DDR3 memory uses less power. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current. [10]According to JEDEC, [11]: 111 1.575 volts should be considered the absolute maximum when memory stability is the foremost consideration, such as in servers or other mission-critical devices.

    en.wikipedia.org/wiki/Memory_rank

    Modern DIMMs can for example feature one rank (single rank), two ranks (dual rank), four ranks (quad rank), or eight ranks (octal rank). [ citation needed ] 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 .

    Dual Channel DDR3 integrated memory controller for Desktop and Server/Workstation Opteron 42xx "Valencia"; [27] Quad Channel DDR3 Integrated Memory Controller [28] for Server/Workstation Opteron 62xx "Interlagos" AMD claims support for two DIMMs of DDR3-1600 per channel. Two DIMMs of DDR3-1866 on a single channel will be down-clocked to 1600.

    The 8n prefetch architecture is combined with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write operation for the DDR4 SDRAM consists of a single 8 n -bit-wide 4-clock data transfer at the internal DRAM core and 8 corresponding n -bit-wide half-clock-cycle data transfers at the I/O pins.
