What is DDR DIMM?
A computer uses RAM (Random Access Memory) installed in “sticks” on the motherboard. RAM acts as a temporary space for rapid retrieval and storage of commonly accessed data. One type of RAM is the DDR DIMM.DDRDDR stands for Double Data Rate. Data rate is measured by a clock cycle whose speed moves according to the megahertz of the RAM. DDR transfers data twice per clock cycle, instead of once.DIMMDIMM stands for Dual Inline Memory Module. A “memory module” is the technical name for the “stick” that fits into slots on your motherboard. “Dual inline” means that the module is 64-bit, whereas SIMMs (Single Inline) are 32-bit.Memory Bit WidthsA SIMM has a 32-bit “data path.” This is like 32 “lanes” of traffic. A DIMM is 64-bit, so its data path is doubled. More information can be processed in a given amount of time.Data Path ProcessingCPUs (Central Processing Units) starting with the Pentium had 64-bit data paths. In order to keep up, you had to install two SIMMs at a time. DIMMs eliminated
