Exact-match DDR5-4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5-4800 (PC5-38400) Registered ECC RDIMMs built to 1.10V and CL40 timing. The 2Rx8 rank structure and 288-pin form factor match the Supermicro H13SVW-NT-OS2 motherboard requirements for full-capacity recognition at rated speed.

Verified fitment for populated servers

The Registered architecture offloads the memory controller so every slot can run fully populated at full capacity while ECC corrects single-bit errors on the fly. Consult your system manual for supported capacities and approved DIMM population order before installation to ensure compatibility.

Suited for Supermicro H13SVW-NT-OS2 upgrades

Ideal for administrators expanding memory in this specific Supermicro platform with validated Registered ECC modules. Not suitable for systems requiring UDIMM or SODIMM form factors, non-ECC memory, or different voltage and timing specifications.

Questions about this item

Will these 288-pin RDIMM modules fit the DIMM slots on my Supermicro H13SVW-NT-OS2 motherboard?

Yes, the kit uses the 288-pin RDIMM form factor that the board requires. It is not a UDIMM or SODIMM, so the keying and height match the server slots exactly.

What is the correct installation order for the two 32 GB sticks on the H13SVW-NT-OS2?

Consult the motherboard manual for the approved DIMM population sequence. The board's memory-controller rules dictate which slots must be filled first for dual-channel operation and full 64 GB recognition.

Do these modules have a heat spreader that could need cleaning or replacement later?

No, the DIMMs ship without a heat spreader. The bare PCB and major-OEM DRAM chips require no user-serviceable parts; only occasional dust removal with compressed air is needed.
