64 GB dual-module kit of DDR5 4800 ECC registered RDIMM memory for Supermicro GPU SuperServer systems

  • Capacity64GB (2 x 32GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 64 GB capacity with two 32 GB modules
  • DDR5 4800 MT/s speed rated PC5-38400
  • ECC registered RDIMM for data integrity
  • 1 V low-voltage operation reduces power draw
  • Validated for Supermicro SYS-821GE-TNHR SYS-821GV-TNR SYS-421GE-TNRT

Target System Compatibility

This 64 GB kit is built for the Supermicro GPU SuperServer platforms SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. It delivers two 32 GB registered DDR5 modules that match the motherboard slot layout and firmware expectations of those servers. The kit is aimed at administrators expanding memory in these exact qualified systems.

Suitable Use Cases

It suits IT teams adding ECC registered capacity to the listed Supermicro servers for virtualization, database or GPU compute workloads. Builders working with unbuffered UDIMM slots, consumer motherboards or any platform not named in the compatibility list should look elsewhere, as the registered signal and pin-out will not function in those environments.

Decisive Specification

The modules run at DDR5 4800 with a CAS latency of CL40 and operate at 1.10 V as a 1Rx4 registered DIMM. This specific combination of speed, latency, voltage, rank organization and registered buffering determines whether the memory will train and run stably in the target Supermicro platforms.

Questions sur cet article

How does the 4800 MT/s speed behave once installed in a Supermicro SYS-821GE-TNHR?

The kit runs at DDR5 4800 with CL40 latency and 1.10 V, delivering the rated transfer rate on the supported Supermicro platforms listed.

What does the PC5-38400 designation mean for the memory interface?

PC5-38400 is the JEDEC module name for DDR5 4800, confirming the 288-pin RDIMM fits the standard DDR5 server DIMM slot.

What physical slot and clearance does the 288-pin RDIMM need in the SYS-421GE-TNRT?

Each 32 GB module is a standard-height 288-pin DDR5 RDIMM with no heat spreader, so it fits any regular DDR5 RDIMM socket in the listed Supermicro systems.
