Targeted Server Upgrade

This 128 GB kit delivers four 32 GB DDR5 Registered ECC RDIMMs built for the Supermicro H13SVW-NT motherboard. The modules match the board's required 288-pin registered form factor and 2Rx8 rank structure so the memory controller recognises every slot at full capacity.

Registered ECC Stability

Registered buffering offloads the memory controller, allowing all four slots to run fully populated at the rated 6400 MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads.

DDR5 6400 CL52 1.1 V

The kit operates at DDR5 6400 (PC5 51200) with CL52 latency at 1.1 V, the exact speed, timing and voltage the platform expects. Builders needing a different data rate, lower latency or unbuffered DIMMs must select another part.

Questions about this item

Will the 128GB DDR5 ECC RDIMM kit need any firmware updates or component replacements during its service life?

The modules are a fixed hardware kit with no user-serviceable parts; ECC corrects single-bit errors on the fly, and the registered buffer reduces electrical load on the memory controller, so no scheduled maintenance or replacements are required.

What limit appears first when all four 32GB RDIMMs run continuously at DDR5 6400 CL52?

The memory controller’s maximum supported rank count and population rules for the Supermicro H13SVW-NT motherboard determine the practical ceiling; once every slot is filled with 2Rx8 modules at rated speed, further capacity cannot be added without changing the platform.

How much heat and power does the 1.1V registered ECC kit generate under sustained load?

Operating at 1.1V with no heat spreaders, the 4x32GB RDIMMs draw minimal power per module; the registered buffer shifts drive current off the CPU memory controller, so total thermal output stays low even during all-day operation.
