However, such densely stacked memory particles and memory bars are very complex. For example, 64GB LRDIMM bars need to be set to four Rank and 128GB to get eight Rank, which results in high latency and DDR4-2400/2666 to CL20/22.

With single Die 16Gb particles, the complexity of large memory strips can be greatly reduced. 64GB and 128GB need only two or four Rank, respectively, while eight Rank can create 256GB single capacity.

aboutThe serverFor a single memory capacity is more favorable, such as extensible Xeon M series supports six channels, up to 12 memory, single 256GB, single total capacity of up to 3TB, eight channel AMD EPYC is able to do single 4TB.

Of course, the price is unthinkable. Crucial 128GB DDR4 LRDIMM now retails for 3999.99 dollars, and how 256GB gets five thousand or six thousand dollars, and RMB thirty thousand or forty thousand is light.

The specification of SK Hynix single Die 16GB DDR4 particle is divided into two types: 1G × 16G × 8. Each offers 2133 / 2400 / 2666MHz three frequencies, timing 15-15-15 / 17-17-17-17 / 19-19-19, voltage is only 1.2 V. One of the low-frequency has been shipped, high-frequency to wait for the third quarter.
