Server DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 256GB of registered DDR5 memory across four 64GB modules. It is built for servers and workstations that require error-correcting code protection and registered signal integrity. The modules run at 5600MHz with a CL46 latency at 1.10V. Compatibility is validated for the ASRock Rack GENOAD8X-2T/BCM motherboard.

256GB capacity and 5600MHz headroom

Four dual-rank 2Rx4 modules deliver a total of 256GB, giving large memory headroom for virtualization, database caching and multi-tenant workloads. The PC5-44800 rating sustains high throughput while ECC corrects single-bit errors automatically. Registered buffering reduces electrical load on the memory controller, allowing stable operation at full population. Workloads exceeding 256GB or demanding lower latency than CL46 will need a different configuration.

Upgrade from smaller DDR5 RDIMM kits

This kit replaces lower-capacity registered DDR5 sets when the platform supports 64GB modules and the motherboard qualifies the part number MR44800-924K4. The jump is worthwhile when application memory pressure causes swapping or when consolidation ratios are limited by RAM slots. Systems already at the maximum supported capacity or requiring unbuffered memory cannot use this kit.

Questions about this item

Will the 5600MHz DDR5 ECC RDIMM modules run reliably alongside my existing 4800MHz DDR5 registered DIMMs?

The kit operates at 5600MHz PC5-44800 with CL46 latency and 1.1V. When mixed with slower DDR5 RDIMMs the system will downclock all modules to the lowest common speed and tightest supported timings; ECC and registered buffering remain active.

How can I confirm the 256GB quad-channel kit is detected and ECC is active after installation?

Enter the server BIOS or UEFI and verify that all four 64GB 2Rx4 modules appear at 5600MHz with ECC enabled. In the OS use dmidecode, lshw or Windows System Information to confirm 256GB total, registered DDR5 type and ECC status showing "Enabled".

Does the MR44800-924K4 package include only the four 288-pin RDIMMs or are any cables or brackets supplied?

The box contains the 256GB kit as four 64GB DDR5 5600MHz CL46 2Rx4 1.1V 288-pin ECC RDIMM modules. No cables, brackets, heatsinks or additional accessories are included.
