  • 512 GB total capacity from eight 64 GB modules for maximum server density
  • DDR5-4800 speed at CL40 and 1.1 V for rated performance
  • Registered ECC RDIMM architecture corrects single-bit errors and stabilises fully populated slots
  • 288-pin 2Rx4 form factor matches Supermicro H13SST-G memory controller requirements
  • Built with major OEM Samsung, Micron or Hynix chips for enterprise reliability

Exact-Match Server Upgrade

This 512GB kit delivers eight 64GB DDR5-4800 Registered ECC RDIMMs built for the Supermicro H13SST-G motherboard. The modules match the board's required 2Rx4 rank, 1.1V voltage and CL40 timing so the memory controller recognises full capacity at rated speed.

Thermals Noise Power

Registered buffering reduces electrical load on the memory controller when all eight slots are populated, helping the system maintain stable operation without extra cooling measures. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

What the Kit Changes

The package supplies the complete 8x64GB configuration in a single validated kit, removing the need to source individual DIMMs and guess population order. Builders who need a different total capacity or a non-registered form factor must select another product.

Questions about this item

How do I install the 8 x 64GB DDR5 4800 RDIMM kit in the Supermicro H13SST-G and what step is often missed?

Power down, open the chassis, and insert each 288-pin RDIMM into the slots specified by the motherboard manual in the exact population order; the step most often missed is verifying the required DIMM sequence before seating all eight modules.

What maintenance or replacement will the 512GB DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; replacement only occurs if a DIMM fails, which is covered by the lifetime replacement warranty.

What limit appears first when the 2Rx4 DDR5 4800 CL40 kit runs fully populated under sustained load?

The memory controller’s maximum supported capacity and ranked-DIMM population rules define the ceiling; with all eight 64GB 2Rx4 modules installed at 1.1V CL40, you reach that platform limit before any module-level constraint.
