Exact-match upgrade for Supermicro H13SVW-NT

This 128GB DDR5-6400 registered ECC RDIMM is built for the Supermicro H13SVW-NT motherboard. It delivers the precise 2Rx4 rank structure, 1.1V operating voltage and CL52 timing the board's memory controller expects. The 288-pin registered form factor matches the server platform's requirements exactly.

Replaces mismatched or lower-capacity modules

The jump is worth it when your current DIMMs are UDIMMs, SODIMMs or slower DDR5 speeds that prevent full-speed operation. Registered architecture offloads the memory controller so every slot runs fully populated at rated capacity. ECC corrects single-bit errors on the fly to stop silent data corruption before it reaches production workloads.

Fits 288-pin RDIMM slots on qualified Supermicro

Installation follows the motherboard's specific population order and supported capacity limits. Verify the manual for approved DIMM sequences before purchase. No heat spreader means clearance is not increased beyond the standard module height. Buyers who need non-ECC unbuffered memory or consumer desktop form factors should look elsewhere.

Questions about this item

Will this 288-pin RDIMM fit the DIMM slots on my Supermicro H13SVW-NT motherboard?

Yes, the 288-pin Registered RDIMM form factor matches the slots on the Supermicro H13SVW-NT. The board requires RDIMMs, not UDIMMs or SODIMMs, so this module is physically compatible.

What is the correct installation order when populating multiple slots with these 2Rx4 modules?

Consult the Supermicro H13SVW-NT manual for the approved DIMM population sequence. The board's memory-controller rules dictate which slots must be filled first for 2Rx4 Registered ECC modules to run at 6400 MT/s.

Do these Samsung, Micron or Hynix chips require any firmware updates or periodic re-seating over time?

No firmware updates are needed for the DRAM chips themselves. Ensure the motherboard BIOS is current for DDR5-6400 support; the modules are solid-state with no moving parts, so re-seating is only required if a slot contact oxidises.
