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.

Questions about this item

Will the DDR5-4800 speed run at its rated 4800 MHz once installed in my Supermicro H13SVW-NT-OS1?

Yes, the kit is spec-matched to the board's memory controller, so all six modules are recognised at full capacity and operate at the rated DDR5-4800 speed.

What does the registered ECC RDIMM interface mean for my server's stability?

Registered buffering offloads the memory controller, allowing every slot to run fully populated, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Do these 288-pin RDIMMs fit the DIMM slots on the H13SVW-NT-OS1 motherboard?

Yes, the 288-pin DDR5 RDIMM form factor is exactly what the board requires; it is not a UDIMM or SODIMM and matches the motherboard's population rules.
