Speed 4800MHz

  • 768GB total capacity from six 128GB modules enables large-scale workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput for Supermicro H13SVW-N
  • ECC registered RDIMM design corrects single-bit errors and stabilises fully populated slots
  • 1V operation matches server memory-controller requirements for reliable recognition
  • 288-pin DDR5 RDIMM form factor fits the exact motherboard memory-population rules

Exact-match server upgrade

This 768GB kit contains six 128GB DDR5 RDIMM modules built for the Supermicro H13SVW-N motherboard. Each module is a registered ECC DIMM that the board recognises at full capacity and rated speed. The 288-pin form factor matches the server's memory slots precisely.

Registered ECC with 2Rx4 organisation

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V. Registered buffering offloads the memory controller so all six slots operate fully populated, while on-die ECC corrects single-bit errors before they reach production workloads. The 2Rx4 rank structure is the exact configuration the platform expects.

Six-module kit only

The package delivers the complete 6x128GB set with no additional cables, software or heat spreaders. Installation follows the motherboard manual's population order and capacity limits. Buyers who need a different total capacity or a UDIMM form factor cannot use this kit.

Questions about this item

Will 768GB run at DDR5 4800 in a Supermicro H13SVW-N?

The kit is an exact-match upgrade for the H13SVW-N motherboard, so the memory controller recognises the 2Rx4 registered ECC modules at full capacity and rated speed.

What does PC5-38400 mean for this memory?

PC5-38400 is the DDR5 4800 module designation; it confirms the 4800 MT/s data rate and CL40 timing your server expects.

Do these modules fit the Supermicro H13SVW-N slots?

Yes, they are 288-pin registered RDIMMs, the form factor the H13SVW-N requires, and the kit matches the board's population rules.
