Exact-match 128 GB DDR5-6400 RDIMM

This 128 GB DDR5-6400 (PC5-51200) registered ECC RDIMM is built for the Supermicro H13SVW-N motherboard. It runs at 1.10 V with CL52 latency and a 2Rx4 rank layout that the board's memory controller expects. The 288-pin module uses major OEM DRAM chips and has no heat spreader.

Straightforward server DIMM install

Power down the system, open the chassis and align the 288-pin key with the slot; the registered design means every populated slot runs at full rated speed. Common issues are ignoring the manual's population order or mixing ranks, which prevents the system from recognising the full 128 GB capacity.

For Supermicro H13SVW-N capacity upgrades

Suits administrators adding maximum registered ECC memory to this specific board within its approved population rules. Not for desktops or workstations that require unbuffered UDIMMs, nor for any system that cannot accept 2Rx4 registered DDR5 modules at 1.10 V.

Questions about this item

How can I confirm the 128GB DDR5 6400 module is running at CL52 and 1.1V after installing it in my Supermicro H13SVW-N?

Enter the server BIOS or use a hardware monitoring tool such as IPMI to verify the memory speed shows 6400 MT/s, the CAS latency reads 52, and the voltage reports 1.10V for the installed RDIMM.

What does the package contain and are any extra components required for installation?

The box includes one 128GB 288-pin DDR5 ECC Registered RDIMM rated at 6400 MT/s CL52 1.1V; no additional cables, brackets, or heat spreaders are needed for the Supermicro H13SVW-N DIMM slots.

Should I choose the 2Rx4 128GB version or a different rank or capacity for the H13SVW-N?

Select the 2Rx4 128GB DDR5-6400 RDIMM when your motherboard manual lists that exact rank, voltage, and capacity combination as supported for full-speed operation in the required population order.
