64GB DDR5-4800 ECC RDIMM Upgrade

This 64GB DDR5-4800 (PC5-38400) module is a Registered ECC RDIMM built for the Supermicro H13SVW-NT-OS2 motherboard. It runs at 1.1V with CL40 latency and a 2Rx4 rank structure. The 288-pin form factor matches the board's DDR5 slots exactly.

Ideal for servers needing maximum registered

Suits administrators expanding memory on the validated Supermicro platform where registered ECC is required for full-slot population and error correction. Not for workstations or desktops that accept only unbuffered UDIMMs, nor for systems limited to lower-density modules or different DDR generations.

Straightforward 288-pin installation

Align the key notch with the DDR5 slot and press firmly until the retention clips engage. Follow the motherboard manual for the correct population sequence when filling multiple channels. The most common issue is mixing registered and unbuffered DIMMs or skipping the prescribed slot order, which prevents the system from posting.
