NEMIX RAM
256 GB kit of four 64 GB DDR5 RDIMMs running at 6400 MHz with CL52 latency, 1.1 V registered ECC and 4Rx4 organisation for the Supermicro X14SDV-36CE-SP3F motherboard
Size 256GB 4X64GB
This 256 GB kit contains four 64 GB registered DDR5 modules rated at 6400 MHz with CL52 latency and 1.10 V operation. It is built for Supermicro X14SDV-36CE-SP3F motherboards that require 288-pin ECC RDIMMs populated in matched sets.
The 4Rx4 registered design lets every slot run fully populated at rated speed while on-die ECC corrects single-bit errors without halting the system. Builders who need unbuffered UDIMMs, SODIMM form factors, or non-ECC memory for desktop platforms should look at something else.
Each 288-pin RDIMM installs directly into the board's DDR5 slots following the manual's population order, with no extra power cables or cooling hardware required. The registered buffer reduces electrical load on the memory controller, freeing headroom for maximum DIMM counts in multi-socket chassis.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
The board must accept 288-pin DDR5 RDIMMs, run at 1.1 V, and allow 4Rx4 registered ECC modules so the kit is recognised at full capacity and at DDR5-6400 speed.
Mixing ranks is possible only if the motherboard's memory-population rules allow it; the manual lists approved DIMM order and maximum ranks per channel for full-speed operation.
Check the BIOS memory information or the OS memory report — both should show 256 GB total, 6400 MT/s data rate, CL52 latency, 1.1 V, and ECC enabled.
