16 GB DDR5-5600 ECC UDIMM for ASUS motherboards

This 16 GB DDR5 module runs at 5600 MT/s with CL46 latency and 1.10 V operation. It uses a single-rank 1Rx8 layout and provides error-correcting code for data integrity. The unbuffered 288-pin design fits desktop DIMM slots on compatible ASUS boards.

Suits ECC-capable desktops and workstations.

Builders who need error correction on supported ASUS A620, B650 or Q670 chipsets will benefit from the ECC function. Systems that do not support ECC unbuffered DDR5 cannot use this module, and laptops or small-form-factor boards requiring SO-DIMM or registered memory should look elsewhere.

Single-rank 1Rx8 organisation determines

The 1Rx8 rank structure is the key specification that decides whether the motherboard memory controller can address this DIMM. Verify that the target ASUS board accepts 1Rx8 ECC UDIMM population rules before purchase.

Questions about this item

What motherboard slot does this 288-pin DDR5 UDIMM require?

It fits a standard DDR5 DIMM slot on a motherboard that supports 5600 MT/s ECC unbuffered memory at 1.1 V.

Will this CL46 ECC module run in my ASUS Prime B650M-A II-CSM alongside slower DDR5 sticks?

Yes, the motherboard will down-clock all modules to the speed of the slowest stick while keeping ECC active.

How can I confirm the 1Rx8 module is detected at 5600 MT/s after installation?

Check the BIOS memory information screen or Windows Task Manager — both show speed, rank and ECC status.
