Two green DDR4 server memory sticks with gold contacts and silver heat spreaders

Black Diamond Memory

Black Diamond Memory BD64GX22400MQR96 128GB (2 x 64GB) DDR4 2400 ECC Registered server RAM

SKU CH-57B4-3C9VN MPN BD64GX22400MQR96

Two 64 GB DDR4 2400 ECC registered modules totalling 128 GB for server error correction

  • Capacity128GB (2 x 64GB)
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2400 (PC4 19200)
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 128GB (2 x 64GB)

  • ECC protection prevents data corruption in critical workloads
  • Registered signal buffering enables stable operation at 128GB capacity
  • DDR4 2400 speed delivers 19200 MT/s bandwidth for server tasks
  • Dual 64GB modules provide high density in two slots
  • 4Rx4 rank organisation maximises memory controller efficiency

Capacity and purpose

This kit provides 128GB of DDR4 server memory in two 64GB registered ECC modules. It targets administrators expanding capacity in enterprise servers that require error correction and registered signalling.

Thermals and power

Registered DDR4 modules at 2400 MT/s draw modest power and generate low heat under typical server workloads. Standard chassis airflow is sufficient to maintain stable operating temperatures without additional cooling.

Rank and compatibility

The 4Rx4 organisation increases density per channel, which benefits virtualisation hosts running many simultaneous threads. Systems must support quad-rank registered DIMMs; platforms limited to dual-rank or unbuffered memory cannot use this kit.

Questions about this item

How do I install the 288-Pin DDR4 modules and which step is often missed?

Align the notch on each 288-Pin DDR4 stick with the slot key, press down evenly until both retention clips click, and verify the motherboard detects the full 128GB at DDR4 2400 speed.

What maintenance or replacement will this ECC Registered memory need later?

ECC Registered DDR4 modules have no scheduled maintenance; replace a stick only if the system logs correctable errors that become uncorrectable or if a module fails memtest.

What limit appears first under sustained load with these 4Rx4 modules?

The memory controller typically hits its maximum supported rank count or thermal throttle point before the DDR4 2400 (PC4 19200) bandwidth ceiling is reached.
