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 ...
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.
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.
Bulldozer is the first major redesign of AMD’s processor architecture since 2003, when the firm launched its K8 processors, and also features two 128-bit FMA-capable FPUs which can be combined into one 256-bit FPU. This design is accompanied by two integer clusters, each with 4 pipelines (the fetch/decode stage is shared).
DDR SDRAM employs prefetch architecture to allow quick and easy access to multiple data words located on a common physical row in the memory. The prefetch architecture takes advantage of the specific characteristics of memory accesses to DRAM. Typical DRAM memory operations involve three phases: bitline precharge, row access, column access. Row ...

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.
