  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 64 GB capacity handles heavy server workloads
  • DDR5 4800 speed delivers high data throughput
  • ECC registered design protects data integrity
  • 10 V operation reduces power consumption
  • Validated for Supermicro SYS-531A-I compatibility

Server-grade DDR5 memory for Supermicro workstations

This 64 GB DDR5 4800 module is built for the SuperMicro SuperWorkstation SYS-531A-I and compatible X13SRA-TF motherboards. Registered ECC operation protects data integrity in mission-critical workloads. The single 2Rx4 rank runs at 1.10 V without a heat spreader.

Sustained-load behaviour in registered ECC mode

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC correction handles single-bit errors without halting the system. Samsung, Micron or Hynix DRAM chips are stress-tested under load before shipping.

64 GB capacity in one 288-pin RDIMM

The 64 GB density fits applications that need maximum memory per slot. Buyers who need more than 64 GB per module or non-ECC unbuffered memory must choose a different part.

Questions about this item

Does the 1.1V DDR5 registered DIMM run cooler than higher-voltage modules during all-day server workloads?

Operating at 1.10V, this 64GB DDR5-4800 ECC RDIMM draws less power per module than higher-voltage alternatives, reducing heat output during continuous operation in the SuperMicro SYS-531A-I workstation.

What motherboard slot and chipset support are required to install this 288-pin 2Rx4 module?

The module requires a DDR5 RDIMM slot on a SuperMicro X13SRA-TF or compatible motherboard that supports 2Rx4 registered ECC memory at 4800 MT/s.

Can this 64GB 2Rx4 registered DIMM share channels with other DDR5 RDIMMs in the same SuperMicro workstation?

Yes, the 288-pin DDR5-4800 CL40 2Rx4 registered ECC module can populate compatible channels alongside identical or matched DDR5 RDIMMs on the SuperMicro X13SRA-TF platform.
