About this deal

In April, Hynix announced that it had developed the world's first highest-density 128GB module based on 8 Gbit DDR4 using 20nm technology. The module works at 2133MHz, with a 64-bit I/O, and processes up to 17GB of data per second. DDR4 SDRAM SO-DIMM (MTA18ASF1G72HZ, 8 GB) Datasheet" (PDF). Micron Technology. 2014-09-10.

Independent programming of individual DRAMs on a DIMM, to allow better control of on-die termination. DQ pins terminate high using pseudo-open-drain I/O (this differs from the CA pins in DDR3 which are center-tapped to VTT). [56] AMD's latest AGESA 1.0.0.7c firmware brought many improvements. It has upped the Ryzen processor's ability to run DDR5-6400 at 1:1, up from the previous DDR5-6000. The updated AGESA code also supports high-frequency DDR5 memory up to DDR5-8000 and potentially beyond. The only downside is that it drops the UCLK and MCLK ratio to 2:1 (UCLK: MCLK / 2), imposing a performance penalty. Dual-rank memory is faster than single-rank memory. Tests show that dual-rank memory kits perform better than single-rank memory kits on AMD and Intel platforms. Always buy a single memory kit for your desired capacity. Don't combine two memory modules or kits from the same vendor and product line. Mixing and matching may not always produce a desirable result, and sometimes, manual tweaking is required to achieve stability.

Corsair brings a bit of both in its Vengeance RGB DDR4-3200 kit, providing four 8GB DIMMs (32GB total) at CAS 16 timings for a price that’s reasonably moderate given the recent market trends. And this kit isn’t all about looks; it has the goods where benchmarks are concerned, too.

Do I need DDR4 RAM 2666MHz memory?

Samsung Begins Production of 10-Nanometer Class DRAM". Official DDR4 Memory Technology News Blog. 2016-05-21. Archived from the original on 2016-06-04 . Retrieved 2016-05-23. Unlike previous generations of DDR memory, prefetch has not been increased above the 8n used in DDR3; [9] :16 the basic burst size is eight 64-bit words, and higher bandwidths are achieved by sending more read/write commands per second. To allow this, the standard divides the DRAM banks into two or four selectable bank groups, [10] where transfers to different bank groups may be done more rapidly. Sobolev, Vyacheslav (2005-05-31). "JEDEC: Memory standards on the way". Digitimes. Via tech. Archived from the original on 2013-12-03 . Retrieved 2011-04-28. Initial investigations have already started on memory technology beyond DDR3. JEDEC always has about three generations of memory in various stages of the standardization process: current generation, next generation, and future. In January, Samsung announced the completion and release for testing of a 2GB [1] DDR4 DRAM module based on a process between 30 and 39 nm. [30] It has a maximum data transfer rate of 2133 MT/s at 1.2V, uses pseudo open drain technology (adapted from graphics DDR memory [31]) and draws 40% less power than an equivalent DDR3 module.
