The first DDR4 memory module prototype was manufactured by Samsung and announced in January 2011. [a] Physical comparison of DDR, DDR2, DDR3, and DDR4 SDRAM Front and back of 8 GB [1] DDR4 memory modules. 2005: Standards body JEDEC began working on a successor to DDR3 around 2005, [14] about 2 years before the launch of DDR3 in 2007.
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

At the time of launch, Microsoft deemed Windows 7 (with Service Pack 1) and Windows 8.1 users eligible to upgrade to Windows 10 free of charge, so long as the upgrade took place within one year of Windows 10's initial release date. Windows RT and the respective Enterprise editions of Windows 7, 8, and 8.1 were excluded from this offer.
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.

Both for DDR3 and DDR4, the four timings described earlier are not the only relevant timings and give a very short overview of the performance of memory. 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 ...
The AMD 4700S and 4800S desktop processors are part of a "desktop kit" that comes bundled with a motherboard and GDDR6 RAM. The CPU is soldered, and provides 4 PCIe 2.0 lanes. These are reportedly cut-down variants of the APUs found on the PlayStation 5 and Xbox Series X and S repurposed from defective chip stock.
