Server-ready DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5-4800 registered ECC modules built to the exact timing and voltage the Supermicro H13SVW-NT memory controller expects. Each stick runs at CL40, 1.10V, and 1Rx8 rank so the board recognises the full capacity at rated speed without manual tuning.

64GB capacity with registered buffering

The registered architecture offloads the memory controller, allowing all four slots to run fully populated at 4800 MT/s while ECC corrects single-bit errors on the fly. Workloads that exceed 64GB will need a motherboard that supports higher-density modules or additional memory channels.

DDR5-4800 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s and fixes the pin count at 288, so bandwidth cannot scale beyond this speed without a platform that supports faster DDR5 grades. The 1.10V operating voltage is also defined by the specification and cannot be lowered for power saving.

Questions about this item

Will the 288-pin RDIMM modules fit my Supermicro H13SVW-NT motherboard?

Yes, the kit is verified for the H13SVW-NT and uses the 288-pin Registered RDIMM form factor the board requires.

How do I verify the ECC registered memory is running correctly after installation?

Check the BIOS or UEFI POST screen; it should report 64GB total capacity, DDR5-4800 speed, and ECC active on all four modules.

What comes in the box and do I need anything else to install the 64GB kit?

The box contains four 16GB DDR5-4800 1Rx8 ECC Registered RDIMM modules; no extra cables or tools are required for installation.
