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 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
Memory options include 8 GB, 16 GB, 32 GB or 64 GB DDR4 2400 MHz memory or 8 GB, 16 GB or 32 GB of HyperX DDR4 2933 MHz memory (64 GB kits sold separately). The Area-51 R4 was configurable with Nvidia GeForce 10 series, AMD RX Vega series or AMD Radeon 500 series graphics cards.
[17] [18] For other high-performance workloads, the Surface Book 3 also fell short compared to several key competitors, many of which offer 6 or 8-core processors and up to 64 GB system memory (128 GB in some cases); in contrast, the Surface Book 3 has a low-powered 4-core ultrabook processor and up to 32 GB memory.
DDR5 has about the same 14 ns latency as DDR4 and DDR3. [7] DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. [8] [3] DDR5 also has higher frequencies than DDR4, up to 8GT/s which translates into 64 GB/s (8 gigatransfers/second × 64-bits/module / 8 bits/byte = 64 GB/s) of bandwidth per DIMM.
