SAMSUNG M321R8GA0EB2-CWM 64 GB DDR5-5600 server RAM

SKU CH-HZQF-ZKGBD MPN M321R8GA0EB2-CWM

64 GB DDR5 server module with ECC, registered signalling, 5600 MHz speed and 1.10 V operation in a 288-pin DIMM

  • 64 GB capacity supports large server workloads
  • DDR5 technology runs at 5600 MHz for high throughput
  • ECC registered design detects and corrects memory errors
  • 10 V operation reduces power draw under load
  • 288-pin DIMM form factor fits standard server slots

Server-grade DDR5-5600 capacity

This 64 GB DDR5 module runs at 5600 MHz and is built for server platforms that require registered ECC memory. It suits administrators scaling memory in multi-socket systems or virtualisation hosts where density and data integrity matter.

Registered ECC with 288-pin DIMM layout

The module uses a registered signal-processing design and on-die ECC to reduce electrical load on the memory controller while correcting single-bit errors. Its 288-pin DIMM form factor fits standard DDR5 server slots and operates at the specified 1.10 V.

DDR5-5600 bandwidth ceiling

The PC5-44800 standard caps peak transfer rate at the rated frequency, so workloads needing higher throughput must add more channels or modules rather than rely on faster speeds. Systems limited to lower DDR5 data rates will downclock this module accordingly.

Questions about this item

What bandwidth does the DDR5-5600/PC5-44800 standard deliver in practice?

The DDR5-5600/PC5-44800 standard provides up to 44 800 MB/s of peak bandwidth per module.

What physical slot and pin count does this 288-pin DIMM require?

It fits a standard DDR5 288-pin DIMM slot on a server motherboard.

How is the module installed and what step is often missed?

Align the notch with the slot key, press down until both retention clips click, and ensure the registered module is seated fully for proper signal integrity.
