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.
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.

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 .
Pascal Le Segretain/Marc Piasecki/Taylor Hill/Getty Images. Yes, yes and yes. ‘90s hair is having its moment—from ‘The Rachel,’ to ‘The Bixie’—so it’s no surprise that flipped ends ...
Synchronous graphics RAM (SGRAM) is a specialized form of SDRAM for graphics adaptors. It is designed for graphics-related tasks such as texture memory and framebuffers , found on video cards . It adds functions such as bit masking (writing to a specified bit plane without affecting the others) and block write (filling a block of memory with a ...
