Server Memory Kit

This 384GB NEMIX RAM kit supplies twelve 32GB DDR5 RDIMMs rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the Supermicro H13SST-GC motherboard and delivers registered ECC stability for production servers.

Suited Use

The 2Rx8 registered ECC design meets the needs of administrators who must populate every slot on an H13SST-GC board at full rated speed. Builders using consumer boards, laptops, or systems that require unbuffered UDIMMs or SODIMMs cannot use this kit.

Deciding Specification

The motherboard demands 288-pin DDR5 RDIMMs with a 2Rx8 organization, 1.10V voltage and CL52 timing; this kit matches those exact parameters so the memory controller recognises the full 384GB capacity at 6400MHz.

Questions about this item

How much power does the 384GB DDR5 6400MHz kit draw when all twelve modules run continuously?

Each 32GB registered DIMM operates at 1.1V, so the full 12-module kit stays at the standard DDR5 server voltage without extra power overhead.

What motherboard slot type and population rules does the Supermicro H13SST-GC require for this 12 x 32GB RDIMM kit?

The board needs 288-pin DDR5 RDIMM slots and follows its manual's population order; the kit matches the exact 2Rx8 registered layout the controller expects.

Will the CL52 2Rx8 registered ECC modules work alongside any existing DDR5 RDIMMs I keep in the same server?

Mixing ranks or timings can prevent full-speed operation; the manufacturer advises checking the motherboard manual for approved population rules before adding these modules.
