System-specific DDR5 ECC UDIMM kit

This 64 GB kit contains four 16 GB unbuffered DDR5 modules rated at 5600 MT/s with CL46 latency and 1.10 V operation. It is built for the ASRock Rack W880D4U-2L2T motherboard and uses major OEM DRAM chips in a 1Rx8 configuration. ECC error correction is included for data integrity in server and workstation roles.

Suited for compatible ASRock Rack servers

The kit targets administrators upgrading the named ASRock Rack platform where unbuffered ECC UDIMMs are required. It is not for systems that need registered DIMMs, lack ECC support in the memory controller, or use a different DDR generation than DDR5. Builders without the exact ASRock Rack model should verify motherboard qualification before purchase.

DDR5 5600 CL46 1.10 V unbuffered ECC specification

The decisive specification is the DDR5 5600 MT/s speed combined with CL46 latency at 1.10 V in an unbuffered ECC UDIMM form factor. This electrical and timing profile must match the motherboard memory controller requirements; a different speed grade, voltage, or buffering type will prevent the system from posting.

Questions about this item

Does this kit require an ASRock Rack W880D4U-2L2T motherboard to run?

The kit is validated for the ASRock Rack W880D4U-2L2T. It also works in other DDR5 platforms that accept 1Rx8 ECC unbuffered UDIMMs at 5600 MT/s and 1.1 V, provided the board supports 288-pin modules.

Can I mix these 5600 MT/s CL46 modules with slower DDR5 ECC UDIMMs I already own?

The motherboard will clock all installed DIMMs to the speed of the slowest module. Mixing is possible if the older sticks are also 1Rx8 ECC unbuffered UDIMMs, but the kit will run at the lower frequency and looser timings of the existing memory.

How do I confirm the system is using ECC correction after installing the four 16 GB sticks?

Enter the BIOS or UEFI and verify that ECC is reported as enabled and that 64 GB total capacity is shown. In the OS, check dmesg on Linux or Event Viewer on Windows for corrected-error counters, which prove the 1Rx8 ECC function is active.
