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 ...
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.
While LGA 2011 was designed for high-end desktops and high-performance servers, LGA 1356 was designed for the dual-processor and low-end segment of the server market. It supports 64-bit wide DDR3 triple channel memory, and equipped with 1 Intel QPI connection and 24 PCI Express lanes.
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.
nForce is a motherboard chipset created by Nvidia originally for AMD Athlon and Duron, with later revisions also supporting contemporary Intel processors. The chipset shipped in 3 varieties; 220, 415, and 420. 220 and 420 are very similar with each having the integrated GPU, but the 220 only has a single channel of memory available whereas 420 has the 128-bit TwinBank design.
A memory controller, also known as memory chip controller (MCC) or a memory controller unit (MCU), is a digital circuit that manages the flow of data going to and from a computer's main memory. [ 1 ] [ 2 ] When a memory controller is integrated into another chip, such as an integral part of a microprocessor , it is usually called an integrated ...
Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
DDR memory bus width per channel is 64 bits (72 for ECC memory). Total module bit width is a product of bits per chip and number of chips. It also equals number of ranks (rows) multiplied by DDR memory bus width. Consequently, a module with a greater number of chips or using ×8 chips instead of ×4 will have more ranks.
