576GB DDR5 ECC RDIMM kit for Supermicro

This 576GB kit contains six 96GB DDR5 6400MHz PC5-51200 2Rx4 1.1V CL52 288-pin ECC RDIMM modules. It is built for the Supermicro Hyper SuperServer SYS-122HA-TN-LCC and targets servers or workstations that require registered ECC memory at this capacity and speed.

Installation notes and common issues

The modules are 288-pin DDR5 RDIMMs that seat in the server's DIMM slots; installation typically takes minutes when following the system manual. Because each module is a 2Rx4 registered ECC part, the platform must support registered memory and the correct population order; mixing with unbuffered or non-ECC DIMMs will prevent boot.

DDR5 RDIMM practical limits

DDR5 RDIMMs operate at 1.1V and use on-die ECC with a registered clock driver that adds one cycle of latency compared with unbuffered modules. The registered buffer improves signal integrity at high capacity but limits maximum frequency scaling; the kit runs at 6400MHz CL52 within the JEDEC PC5-51200 standard. Systems that do not support registered ECC DDR5 cannot use these modules.

Questions about this item

How do I confirm the 6400MHz CL52 ECC RDIMM kit is running correctly after installing it in my SYS-122HA-TN-LCC?

Enter the server BIOS or UEFI and verify the memory frequency shows 6400MT/s, CAS latency reads CL52, voltage is set to 1.1V and the ECC status reports enabled across all six 96GB modules.

What ships in the MR51200-9624K6 package and what extra items are required?

The box contains six 96GB DDR5 288-pin ECC RDIMM modules totalling 576GB; no heat spreaders, cables or tools are included and nothing else must be purchased for a standard installation.

Which NEMIX RAM DDR5 kit should I choose for the Supermicro SYS-122HA-TN-LCC if I need maximum registered ECC capacity?

Select the MR51200-9624K6 576GB (6×96GB) DDR5 6400 CL52 1.1V 2Rx4 RDIMM kit, as it matches the server’s validated memory specification exactly.
