Samsung DDR4-3200 ECC RDIMM Spec and Price in Canada

DDR41x64GBRDIMM13.75 ns true latency

Samsung's M393A8G40BB4-CWE is the 64GB DDR4-3200 registered module, 2Rx4 ranks at CL22 and 1.2V per the listing that carries the part number. It tops the DDR4 RDIMM ladder — 3200 MT/s is the highest standard speed DDR4 servers boot — for the later EPYC and Xeon Scalable platforms that accept it, and its part number names the compatibility target for 64GB DDR4 registered memory aftermarkets.

Tied 13th of 18 models in the Server RAM catalog on Speed — 4 models share this figure.
