Capacity and configuration

This NEMIX RAM kit delivers 512GB across four 128GB DDR5 RDIMMs. It is built for servers and workstations that require maximum registered ECC memory capacity in a fully populated four-slot layout.

Speed, latency and voltage

Modules run at 5600 MT/s (PC5-44800) with CL46 timings at 1.1V. The 4Rx4 registered design lets the memory controller drive every slot at rated speed while ECC corrects single-bit errors on the fly.

DDR5 RDIMM platform constraints

DDR5 RDIMMs fit only motherboards wired for 288-pin registered memory; they will not seat in UDIMM or SODIMM slots. Population rules and maximum supported capacity are set by the specific platform, so the system manual must be consulted before installation.

Questions about this item

Will this 512GB kit work alongside my existing DDR5 5600 RDIMMs in the Supermicro X14SDI-36C-SP3F?

This 4x128GB kit uses 4Rx4 registered ECC modules at 1.1V CL46. Mixing ranks or capacities can prevent full-speed operation; populate all four slots with this matched kit for guaranteed 5600MT/s stability.

How do I verify the Supermicro X14SDI-36C-SP3F recognises all 512GB at DDR5 5600 after installation?

Enter the BIOS and confirm the memory training reports 512GB total, DDR5 5600 (PC5-44800) speed, CL46 timings and ECC active on all four 288-pin RDIMM slots.

What is included in the MR44800-744K4 package and do I need extra cooling for the 4Rx4 modules?

The box contains four 128GB DDR5 5600 4Rx4 ECC RDIMMs — no heat spreaders are fitted. Standard server chassis airflow is sufficient; no additional cooling or cables are required.
