256GB DDR5-6400 RDIMM kit

This NEMIX RAM kit delivers 256GB through eight 32GB DDR5 modules running at 6400MHz PC5-51200 with CL52 latency at 1.1V. Each module is a 2Rx4 288-pin ECC Registered RDIMM built for server stability. The matched kit ensures the memory controller recognises full capacity and rated speed immediately.

Verified for Supermicro X14SDW-64C-SP9F

The kit suits administrators populating all slots on the Supermicro X14SDW-64C-SP9F motherboard with registered ECC memory. Builders needing unbuffered UDIMM or SODIMM modules for workstations or laptops should look elsewhere. Systems that cannot run DDR5 at 6400MHz or that require different rank configurations will not accept this kit.

288-pin Registered ECC RDIMM form factor

This product is a 288-pin DDR5 Registered ECC RDIMM. Motherboards wired for UDIMM, SODIMM or earlier DDR generations physically and electrically reject these modules. Confirm the platform demands registered DDR5 RDIMMs before ordering.

Questions about this item

Does the kit include anything besides the eight 32 GB DDR5 RDIMM modules?

The package contains only the eight 32 GB DDR5 6400 MHz CL52 1.10 V ECC Registered RDIMMs; no cables, brackets or software are supplied.

Should I choose this 256 GB 8×32 GB kit or a smaller capacity for my Supermicro X14SDW-64C-SP9F?

Select this kit when you need the full 256 GB across all eight slots; if your workload fits in less memory, a smaller validated kit will cost less and leave slots free for future expansion.

Will the CL52 latency and 6400 MHz speed actually run at those ratings once installed?

Yes — the modules are spec-matched to the board's memory controller, so the system recognises the 2Rx4 registered ECC DIMMs at 6400 MHz PC5-51200 with CL52 timing at 1.10 V.
