  • Total capacity64 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 64 GB capacity expands server memory for heavy workloads
  • DDR5 5600 speed delivers high bandwidth for data-intensive tasks
  • ECC registered design detects and corrects errors to protect data integrity
  • 1 V operation reduces power draw in dense configurations
  • 2Rx4 288-pin RDIMM form factor fits compatible Samsung server boards

Server-grade capacity for registered platforms

This 64 GB DDR5 module is built as a single 2Rx4 registered DIMM with on-die ECC for Samsung server and workstation motherboards. It targets IT professionals who need maximum density per slot in multi-channel configurations.

Low-voltage operation at standard JEDEC speed

The stick runs at 1.10 V and 5600 MT/s with CL40 timing, matching the PC5-44800 spec without overclocking. Registered buffering and the absence of a heat spreader keep power draw predictable in densely populated chassis.

288-pin RDIMM form factor with Samsung qualification

Compatibility is validated against Samsung M321R8GA0PB0-CWM and the MR38400-924K1 part number, so the module works only in systems that accept registered DDR5 ECC DIMMs. Builders using unbuffered consumer boards cannot install it.

Questions about this item

How do I install this 288-pin DDR5 RDIMM and which step is commonly missed?

Align the module key with the slot notch, press straight down until both retention clips click, then verify the server BIOS detects the full 64GB at 5600MT/s — skipping the clip check is the step most often missed.

What maintenance or replacement will this ECC registered module need over time?

No periodic maintenance is required; the module either passes continuous ECC scrubbing or it reports correctable errors, at which point the DIMM should be replaced to maintain data integrity.

What limit appears first when this CL40 1.1V kit runs sustained workloads?

The registered buffer and on-die ECC add latency, so memory-controller throughput saturates before the 1.1V thermal envelope becomes a constraint.
