DDR4 RAM modules feature pins that are spaced more closely at 0.85 mm compared to the 1.0 mm spacing in DDR3, allowing for a higher pin density within the same standard DIMM length of 133.35 mm (5¼ inches). The height of DDR4 modules is slightly increased to 31.25 mm (1.23 inches) from 30.35 mm (1.2 inches
The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed
The DDR4 chips run at 1.2 V or less, [18] [19] compared to the 1.5 V of DDR3 chips, and have in excess of 2 billion data transfers per second. They were expected to be introduced at frequency rates of 2133 MHz, estimated to rise to a potential 4266 MHz [ 20 ] and lowered voltage of 1.05 V [ 21 ] by 2013.
16 GiB DDR4-2666 1.2 V Unbuffered DIMM (UDIMM). DDR, DDR2, DDR3, DDR4 and DDR5 all have different pin counts and/or different notch positions, and none of them are forward compatible or backward compatible. DDR5 SDRAM is the most recent type of DDR memory and has been in use since 2020.

The Joint Electron Device Engineering Council characterizes its standardization efforts as follows: [1] JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the ...
G.SKILL is known for its range of DDR, [4] DDR2, [5] DDR3, [6] DDR4 [6] and DDR5 [7] computer memory. RAM is available in single-channel, dual-channel, triple-channel and quad-channel packs for desktops, workstations, HTPC, as well as netbooks and laptops. [8] It was shown to be the only DDR4 manufacturer not vulnerable to the rowhammer ...
The full memory timings of a memory module are stored inside of a module's SPD chip. On DDR3 and DDR4 DIMM modules, this chip is a PROM or EEPROM flash memory chip and contains the JEDEC-standardized timing table data format.
