  2. DDR4 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR4_SDRAM

    DDR4 speeds are advertised as double the base clock rate due to its Double Data Rate (DDR) nature, with common speeds including DDR4-2400 and DDR4-3200, and higher speeds like DDR4-4266 and DDR4-5000 available at a premium. Unlike DDR3, DDR4 does not have a low voltage variant; it consistently operates at 1.2 V. Additionally, DDR4 improves on ...

  3. DDR SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR_SDRAM

    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

    DDR SDRAM operating with a 100 MHz clock is called DDR-200 (after its 200 MT/s data transfer rate), and a 64-bit (8-byte) wide DIMM operated at that data rate is called PC-1600, after its 1600 MB/s peak (theoretical) bandwidth. Likewise, 12.8 GB/s transfer rate DDR3-1600 is called PC3-12800.

    Small outline RIMM (SO-RIMM). Smaller version of the RIMM, used in laptops. Technically SO-DIMMs but called SO-RIMMs due to their proprietary slot. Compression Attached Memory Module , a standard developed by Dell, which uses a land grid array instead of the more common edge connector. Stacked vis-à-vis non-stacked RAM modules

    Similarly, VLP DDR4 DIMMs are also marginally taller than their DDR3 equivalent at nearly 0.74 inches (19 mm). [ 17 ] As of Q2 2017, Asus has had a PCI-E based "DIMM.2", which has a similar socket to DDR3 DIMMs and is used to put in a module to connect up to two M.2 NVMe solid-state drives.

  7. Kaby Lake - Wikipedia

    en.wikipedia.org/wiki/Kaby_Lake

    Dual channel memory support in the following configurations: DDR3L-1600 1.35 V (32 GB maximum) or DDR4-2400 1.2 V (64 GB maximum) A total of 16 PCIe lanes; The Core-branded processors support the AVX2 instruction set. The Celeron and Pentium-branded ones support only SSE4.1/4.2. 350 MHz base graphics clock rate; No L4 cache (eDRAM)

  8. LPDDR - Wikipedia

    en.wikipedia.org/wiki/LPDDR

    Low-Power Double Data Rate (LPDDR), also known as LPDDR SDRAM, is a type of synchronous dynamic random-access memory (SDRAM) that consumes less power than other random access memory designs and is thus targeted for mobile computing devices such as laptop computers and smartphones.

  9. Synchronous dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Synchronous_dynamic_random...

    DDR4 reached mass market adoption around 2015, which is comparable with the approximately five years taken for DDR3 to achieve mass market transition over DDR2. 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.
