A-Tech 64GB DDR5 6400 ECC RDIMM 2Rx4 1.10V Server RAM

SKU CH-APD4-NTYRK

64GB DDR5-6400 ECC registered server memory with 2Rx4 organisation and 1.10V operation

  • Capacity64GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS Latency32
  • Voltage1.10V
  • ECCYes
  • 64GB capacity expands server memory for heavier workloads
  • DDR5 6400 speed delivers high data throughput for demanding applications
  • ECC RDIMM technology detects and corrects memory errors automatically
  • 10V operation matches DDR5 standard voltage for efficient power use
  • 2Rx4 dual-rank organisation increases memory density per module

Server memory upgrade

This 64GB DDR5 module is built for servers and workstations that require registered ECC memory. It replaces the Samsung M321R8GA0PB1-CCP, M321R8GA0PB2-CCP and M321R8GA0EB2-CCP parts directly. The 288-pin RDIMM form factor fits compatible DDR5 slots in enterprise platforms. Buyers needing unbuffered desktop memory cannot use this module.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC design with a 2Rx4 rank structure. This combination determines whether the system's memory controller can address the module correctly. Speed is rated at DDR5 6400 with CAS latency 32 at the standard 1.10V operating voltage. Systems that require unregistered DIMMs or a different rank configuration will not accept this part.

Major-brand Samsung DRAM ICs

The module uses Samsung chipset components selected for reliability in continuous operation. No heat spreader is included, so airflow in the chassis must be sufficient for the bare PCB. A lifetime warranty and US-based technical support are provided by the brand. Buyers who need pre-installed heat spreaders or bundled configuration software will not find them here.

Questions sur cet article

What does the 6400 MT/s speed mean for actual server throughput?

The module runs at DDR5 6400, delivering up to PC5-51200 bandwidth when the platform memory controller operates at that rate.

How does the 288-pin DDR5 RDIMM interface limit performance?

The registered 288-pin DDR5 DIMM connects through the server memory controller; maximum throughput is capped at the DDR5 6400 PC5-51200 specification.

What physical space and slot type does this 64 GB module need?

It requires a standard 288-pin DDR5 RDIMM slot and fits the same form factor as the Samsung M321R8GA0PB1-CCP replacement.
