  • Total capacity512 GB (8 × 64 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx4
  • Massive 512GB capacity with eight 64GB modules for heavy workloads
  • ECC registered DDR5 at 6400MHz CL52 protects data integrity under load
  • Low 1.10V operation reduces server power draw and heat
  • 288-pin 2Rx4 RDIMM kit validated for SuperMicro SYS-822GS-NB3RT
  • Built with major OEM Samsung Micron Hynix chips for enterprise reliability

Capacity and fit

This 512GB kit delivers eight 64GB DDR5 RDIMMs validated for the SuperMicro SYS-822GS-NB3RT. Registered ECC operation at 6400MHz with CL52 timing suits enterprise workloads that demand data integrity and high density.

Build integration

The 288-pin modules run at 1.1V and use a 2Rx4 organisation, freeing DIMM slots while providing maximum registered capacity per channel. No heat spreaders are fitted, so airflow in dense server chassis remains unobstructed.

Suitability

Operators scaling memory in the named SuperServer platform will match the qualified configuration exactly. Buyers needing unbuffered DIMMs, lower capacities, or modules qualified for different platforms should select alternative kits.

Questions about this item

Does the CL52 latency limit throughput during sustained server workloads?

CL52 is the rated CAS latency at 6400MHz; sustained throughput depends on the SuperMicro SYS-822GS-NB3RT memory controller and workload mix.

How much heat do the eight 64GB modules generate when running continuously at 1.10V?

Registered DDR5 RDIMMs at 1.10V typically stay within standard server thermal envelopes; no heat spreaders are fitted on these modules.

Must the SuperMicro SYS-822GS-NB3RT already have a DDR5 RDIMM slot layout that accepts 2Rx4 modules?

Yes, the kit is 288-pin DDR5 RDIMM 2Rx4 and is validated for the SuperMicro SYS-822GS-NB3RT platform.
