Verified Answerlestie consequat, ultrices ac magna. DIMM stands for Dual In-Line Memory Module, a type of computer memory that installs in the motherboard’s memory slots. While DIMM’s predecessor, SIMM (Single In-Line Memory Module), are 32-bit and must be installed in matched pairs to achieve 64-bit data paths, DIMMs are natively 64 bits. This enables a single DIMM to transfer data twice as fast as a single SIMM. DIMM memory chips are dynamic random access memory (DRAM), the most common type of primary memory. Static RAM is more expensive and faster and creates the CPU’s cache memory layer. DRAM consists of a transistor and capacitor that create a memory cell, which represents a single bit. The DIMM is installed on a motherboard and stores each data bit in separate memory cells.
While earlier DIMM units held a paltry 512 MB of RAM, modern DIMM units like this Samsung DDR4 hold up to 64GB RAM. DIMM ArchitectureDIMM is a printed circuit board with mounted DRAM or SDRAM integrated circuits. SDRAM is Synchronous DRAM that runs at significantly higher clock speeds.
DIMM’s Predecessor: SIMMA SIMM (single in-line memory module) is DIMM’s predecessor. SIMM contains DRAM or SDRAM chips on a printed circuit board. One SIMM has a 32-bit data path; paired identical SIMMs support 64-bit data paths in modern computers. SIMM vs. DIMM
The Question of DIMM SlotsThe ideal number and type of DIMM slots differs according to physical computer sizes and use cases. Computer motherboards support either 2, 4, 6 or 8 DIMMs. Most motherboards are manufactured with 4 slots. Smaller motherboards may have 2; high-end motherboards with fast chipsets will have 8. The most common types of DIMM memory chips are DDR4-SDRAM for high-end servers, DDR2- or DDR3-SDRAM for desktops, and SO-DIMM for laptops. SO-DIMM is Small Outline RAM manufactured for laptop motherboards. Advantages of DIMM
There are factors in computing performance greater than the width of the data bus, so multi-channel multipliers do not automatically correspond to performance gains. However, memory technologies like interleaving reduces memory latency in multi-channel DIMMs. Interleaving spreads data in alternating patterns across memory modules. The CPU sequentially accesses data patterns across memory modules, instead of waiting to fill one module before accessing the next one.

Which memory module has 240 pins?DDR2 SDRAM use 240-pin DIMM sockets for desktop computers. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered modules), so they are installed one at a time in 64-bit systems. DDR2 chipsets are expected to support dual-channel memory, providing a 128-bit data path.
How many pins are on a DDR DIMM?Physically, a DDR4 module, or dual in-line memory module (DIMM), looks very similar to a DDR3 DIMM. However, DDR4 has 288 pins compared with DDR3's 240 pins; DDR4 SO-DIMMS have 260 pins instead of 204 in DDR3.
What type of double data rate Sdram uses 288 pins?Modern DIMMs based on double data rate fourth generation (DDR4) SDRAM chips use 288-pin connectors to attach to the computer motherboard to enable the increase in data throughput.
What are the four major categories of memory modules?Memory consists of four types of memory chips RAM, ROM, CMOS and flash.
