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 each other, and many motherboards use both by using DDR memory in a dual-channel ...
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. The electrical connections between the memory controller and the DRAMs are almost identical (with the possible exception of which chip selects go to which ranks). Increasing the ...
A typical computer has only a single memory controller with only one or two channels. The logical features section described NUMA configurations, which can take the form of a network of memory controllers. For example, each socket of a two-socket AMD K8 can have a two-channel memory controller, giving the system a total of four memory channels.
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 DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
Therefore, when using a 16-bit RIMM, it is necessary to install two or four RIMMs of the same capacity and speed and use them in dual channel (a 32-bit RIMM can operate with one). Also, since it is necessary to install a dummy module called C-RIMM in the memory socket that does not have RIMM installed, many motherboards bundled C-RIMM.
Both have 2 MB of memory and PCI port. Cirrus Logic GD5465 has extended 4 MB Rambus memory, dual-channel memory support and uses faster AGP port. [14] RDRAM offered a potentially faster user experience than competing DRAM technologies with its high bandwidth. The chips were used on the Creative Graphics Blaster MA3xx series, among others.
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 ...
