ECC UDIMM kit for ASUS DDR5 motherboards

This 64 GB kit contains two 32 GB DDR5 4800 modules built for ASUS Prime A620M-A-CSM, Pro B650M-CT-CSM, Prime B650M-A II-CSM and Pro Q670M-C-CSM motherboards. ECC error correction and unbuffered operation suit workstations and small servers that need data integrity without registered memory. Buyers who need registered DIMMs or higher speeds cannot use this kit.

Package contents and software impact

The box delivers only the two 288-pin UDIMMs; no heat spreaders, cables, adapters or software utilities are included. ECC functionality is handled entirely by the motherboard and BIOS, so the modules add no extra management layer. Systems without ECC support in the chipset or BIOS will not gain error correction from these sticks.

Installation notes and common pitfalls

Each module slots into a standard 288-pin DDR5 socket at 1.1 V with CL40 2Rx8 timing; no tools or firmware updates are required beyond the board's normal memory training. The most frequent issue is mixing these ECC UDIMMs with non-ECC or registered modules, which prevents the system from posting. Populate the slots specified in the motherboard manual for dual-channel operation.

Questions about this item

Will the 32GB DDR5 modules need any periodic maintenance or component replacement over time?

No, DDR5 UDIMMs have no moving parts or user-serviceable components; they operate maintenance-free for their service life.

What thermal limit appears first when the 4800 CL40 kit runs continuously at 1.10 V?

The memory controller's temperature threshold is reached before the unbuffered modules themselves, since they lack a heat spreader and rely on case airflow.

How much power does the 64GB 2Rx8 kit draw and how audible is it during all-day workloads?

At 1.1 V the pair draws only a few watts and is completely silent — there are no fans or coils on the bare PCB.
