ASUS DDR5 ECC UDIMM kit for workstations

This 64 GB kit contains four 16 GB DDR5 modules rated at 5600 MT/s with CL46 latency and 1.1 V operation. The unbuffered ECC design targets data-integrity workloads on compatible ASUS motherboards. No heat spreaders are fitted, keeping the profile low for dense builds.

Fits four 288-pin DDR5 slots on listed ASUS boards

The kit is validated for Prime A620M-A-CSM, Pro B650M-CT-CSM, Prime B650M-A II-CSM and Pro Q670M-C-CSM platforms. Each module is a single-rank 1Rx8 device using major OEM Samsung, Micron or Hynix chips. Unbuffered signalling means no registered buffer is required on the memory controller.

Replaces non-ECC or lower-capacity DDR5 kits

Builders moving from standard unbuffered DDR5 without error correction gain ECC protection for silent data corruption. The jump is worthwhile when the platform supports ECC UDIMM and the workload demands 64 GB across four channels. Systems limited to two slots cannot use the full kit.

Questions about this item

Will the CL46 latency become a bottleneck during sustained heavy workloads?

The kit runs at DDR5 5600 with CL46 timings and 1.10 V; latency is fixed by the JEDEC profile and does not change under load.

How much heat do four unbuffered ECC UDIMMs generate when running all day?

These 1Rx8 modules operate at 1.10 V without heat spreaders; typical power draw stays within standard DDR5 UDIMM limits for continuous operation.

Which motherboard must I already own for this 288-pin kit to work?

The kit is validated for ASUS Prime A620M-A-CSM, Pro B650M-CT-CSM, Prime B650M-A II-CSM and Pro Q670M-C-CSM motherboards.
