NEMIX RAM DDR5 4800 384GB 6x64GB CL40 1.1V ECC RDIMM Supermicro H13SVW-NT-OS1 memory upgrade

Exact-fit server memory kit

This NEMIX RAM DDR5 kit delivers 384GB across six 64GB RDIMMs built for the Supermicro H13SVW-NT-OS1 motherboard. Each module is a 288-pin Registered ECC DIMM rated at 4800MHz PC5-38400 with CL40 latency and 1.10V operation. The 2Rx4 rank structure matches the board's memory controller expectations for full-capacity recognition. Buyers needing a different form factor or non-ECC memory should look elsewhere.

Registered ECC with 2Rx4 rank

The registered (buffered) architecture reduces electrical load on the memory controller, allowing all six slots to run populated at the rated 4800MHz speed. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. Systems that require unbuffered UDIMMs or lack support for registered modules cannot use this kit.

Six-module kit, no heat spreaders

The package contains exactly six 64GB RDIMMs with no additional accessories, software, or heat spreaders. Installation follows the motherboard's specific DIMM population order, which must be verified in the Supermicro manual before purchase. No cables, drivers, or configuration utilities are included or required.
