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 ...
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.
Cache memory is typically SRAM, while the main memory is typically DRAM. [27] RAM is volatile, meaning its contents will disappear if the computer powers down. [57] Permanent storage or non-volatile memory is typically higher capacity and cheaper than memory, but takes much longer to access.
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 ...
DDR4 is not compatible with any earlier type of random-access memory (RAM) due to different signaling voltage and physical interface, besides other factors. DDR4 SDRAM was released to the public market in Q2 2014, focusing on ECC memory , [ 6 ] while the non-ECC DDR4 modules became available in Q3 2014, accompanying the launch of Haswell-E ...
This way, only the offending program crashes, and other programs are not affected by the misbehavior (whether accidental or intentional). Use of protected memory greatly enhances both the reliability and security of a computer system. Without protected memory, it is possible that a bug in one program will alter the memory used by another program.
A high-capacity DIMM might have numerous memory chips, each of which must receive the memory address, and their combined input capacitance limits the speed at which the memory bus can operate. By redistributing the command and address signals within the R-DIMM, this allows more chips to be connected to the memory bus. [7]
LGA 1200, also known as Socket H5, is a zero insertion force flip-chip land grid array (LGA) socket, compatible with Intel desktop processors Comet Lake (10th gen) and Rocket Lake (11th-gen) desktop CPUs, which was released in April 2020.
