  • 288-pin RDIMM form factor fits the motherboard's memory-population rules

Server-grade DDR5 ECC RDIMM kit

This 256 GB kit comprises two 128 GB DDR5 5600 registered ECC modules built for the Supermicro H13SVW-NT motherboard. The 2Rx4 organisation and 1.10 V operation match the board's memory-controller requirements exactly. It is not for systems that accept only unbuffered UDIMMs or SODIMM form factors.

Thermals and power in normal use

Running at the standard 1.10 V keeps power draw low across both DIMMs during typical server workloads. The modules ship without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation when all slots are populated.

Build quality and daily handling

Major OEM Samsung, Micron or Hynix chips underpin the lifetime replacement warranty and free US-based technical support. The 288-pin RDIMM connector keys only into registered DIMM slots, so installation follows the motherboard's prescribed population order. Verify the manual for supported capacities and slot sequence before seating the modules.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro H13SVW-NT, and which slot order is the one people get wrong?

Install both 128 GB RDIMMs in the exact DIMM population order listed in the Supermicro H13SVW-NT manual; the board requires registered DDR5 modules in specific channels to recognise the full 256 GB at 5600 MT/s.

What maintenance or replacement will the 2Rx4 ECC RDIMM kit need over its service life?

The modules have no moving parts or heat spreaders; ECC corrects single-bit errors on the fly, and the lifetime replacement warranty covers any module that develops uncorrectable faults.

What limit appears first when the 5600 MT/s CL46 1.1 V kit runs fully populated under sustained load?

The memory controller’s maximum supported capacity and ranked-population rules are the first ceiling; the 2Rx4 registered design lets all slots run at rated speed, but the platform caps total addressable memory.
