Speed 4800MHz

  • 48 GB capacity lets the server run large workloads without swapping
  • DDR5 4800 speed delivers rated throughput for the memory controller
  • CL40 latency at 1.1 V matches the board's timing expectations
  • 2Rx8 registered ECC corrects single-bit errors and supports full-slot populations
  • 288-pin RDIMM form factor fits the Supermicro H13SVW-N motherboard exactly

Supermicro H13SVW-N DDR5 ECC RDIMM

This 48GB DDR5 4800 CL40 2Rx8 registered ECC module is built for the Supermicro H13SVW-N motherboard. It matches the board's required 288-pin RDIMM form factor, 1.1V operation, and registered architecture. System administrators upgrading memory in compatible Supermicro servers use it to add capacity while maintaining full-speed operation.

Replacing slower or smaller registered ECC DIMMs

Swapping out lower-capacity RDIMMs or mixed-speed kits removes population mismatches that can force the memory controller to downclock. The jump is worth it when the server manual confirms 48GB single-rank or dual-rank support per slot and the current configuration limits total memory or forces reduced frequency.

Installing in the correct DIMM slots

Installation follows the motherboard's documented population order for registered ECC memory. The modules are keyed for 288-pin DDR5 slots and require no heat spreader clearance. What usually goes wrong is ignoring the manual's slot sequence or mixing ranks, which can prevent the system from posting or recognizing the full 48GB capacity.

Questions about this item

Does the 288-pin RDIMM fit the Supermicro H13SVW-N motherboard slots?

Yes. The module is a 288-pin DDR5 RDIMM, the exact form factor the H13SVW-N requires; it is not a UDIMM or SODIMM.

What is the correct population order when installing this 2Rx8 module on the H13SVW-N?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory rules dictate which slot must be filled first for proper recognition.

Will the registered ECC design reduce the need for future DIMM replacements?

Registered buffering offloads the memory controller and ECC corrects single-bit errors on the fly, lowering stress that can lead to premature module failure.
