System-specific DDR5 kit

This 512GB kit consists of four 128GB DDR5 ECC RDIMM modules built for the ASRock Rack W890D8-2L2T motherboard. Registered buffering and on-die ECC target server and workstation workloads that require data integrity. The kit arrives new and ready for installation in compatible 288-pin slots.

512GB capacity at 6400MHz

Four quad-rank 4Rx4 modules deliver 512GB total capacity while operating at 6400MHz with CL52 latency. The 1.10V voltage supports dense memory configurations within typical server power envelopes. Workloads exceeding 512GB or requiring lower latency than CL52 will need a different solution.

Registered ECC RDIMM build

Each module uses a 288-pin DDR5 RDIMM form factor without a heat spreader, relying on chassis airflow for cooling. Registered signalling reduces electrical load on the memory controller when all four slots are populated. ECC capability corrects single-bit errors to maintain uptime in critical applications.

Domande su questo articolo

Will the 6400MHz CL52 modules run alongside slower DDR5 DIMMs already installed in the ASRock W890D8-2L2T?

The kit operates at 6400MHz with CL52 latency; mixing speeds forces all DIMMs to run at the slowest installed module's frequency and timings.

How can I verify the 512GB 4Rx4 ECC RDIMM kit is recognised correctly after installation?

Check the BIOS memory information screen for 512GB total capacity, 6400MHz speed, ECC active status and four registered DIMMs detected.

Does the MR51200-744K4 package include only the four 128GB 288-pin DDR5 RDIMMs or are any extra items supplied?

The box contains exactly four 128GB DDR5 6400MHz CL52 1.1V 288-pin ECC RDIMM modules; no cables, brackets or additional hardware are included.
