SAMSUNG M393A8G40AB2-CWE 64GB DDR4 3200 RDIMM ECC 2Rx4

SKU CH-JAEB-0662C

A 64GB DDR4 RDIMM module running at 3200MHz with ECC and 2Rx4 organisation

  • 64 GB capacity in a single module
  • 3200 MHz speed rated at PC4-25600
  • ECC registered design protects data integrity
  • Dual rank 2Rx4 organisation for density
  • JEDEC standard 1.2 V operation

64GB DDR4 RDIMM for server workloads

This single 64GB DDR4 module runs at 3200MHz with ECC and registered buffering. It targets servers and workstations that require error correction and high capacity per slot. The dual-rank 2Rx4 organisation helps populate large memory configurations.

288-pin DIMM installs in keyed DDR4 slots

Alignment notches prevent backward insertion, so the module seats in one orientation only. Registered signalling adds electrical load, so the platform memory controller must support RDIMM operation. Mixing registered and unbuffered DIMMs on the same channel will prevent the system from posting.

CL22 latency at 3200MHz JEDEC standard

The module operates at the standard 1.2V with a CAS latency of 22 cycles. This timing is the primary figure that determines whether the memory matches the platform’s qualified vendor list. Buyers who need lower latency or higher frequency should verify platform support before ordering.

商品問答

How can I verify the module runs at 3200 MHz after installation?

Check the memory speed reported in your system BIOS or a tool such as CPU-Z; it should show 3200 MT/s with timings of CL22 at 1.2 V.

What comes in the package and what must I source separately?

The box contains the single 64 GB DDR4 RDIMM; no cables, brackets or additional modules are included.

Which capacity and rank option should I select for a dual-channel server board?

This part is a single 64 GB 2Rx4 module; add a second identical module to populate both channels.
