  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Massive 512 GB capacity with eight 64 GB modules
  • DDR5 4800 speed rated at PC5-38400 for server workloads
  • ECC registered RDIMM ensures data integrity under load
  • Low 1.10 V operation reduces power draw in dense configurations
  • Validated for SuperMicro SYS-211E and X13SEM platforms

Target systems

This 512 GB kit supplies eight 64 GB DDR5 4800 RDIMM modules built for Supermicro platforms such as the SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF. It is aimed at administrators who need maximum registered ECC capacity in those qualified servers.

DDR5 4800 registered limits

The modules run at 4800 MT/s with CL40 latency at 1.1 V and present a 2Rx4 organisation across 288 pins. Registered buffering and on-die ECC are mandatory for the target platform, so unbuffered or non-ECC DIMMs cannot be used as substitutes.

512 GB total capacity

The kit delivers 512 GB in a single validated configuration; systems that cannot address this density or that require fewer than eight slots will not be able to use the full kit.

Questions about this item

Should I choose the 8 x 64 GB kit or buy single modules?

The 512 GB kit provides eight matched 64 GB modules tested together, ensuring full population of the 288-pin DDR5 slots without mixing batches.

What does the 4800 MT/s rating deliver in a SuperMicro server?

The PC5-38400 modules run at DDR5 4800 with CL40 latency and 1.1 V, giving the rated bandwidth when all channels are populated on the X13SEM-F or X13SEM-TF.

How does the 288-pin RDIMM interface limit capacity per slot?

Each registered 2Rx4 module presents 64 GB per slot; the eight-module kit reaches 512 GB total while maintaining ECC integrity across the registered bus.
