16 GB DDR4-3200 ECC UDIMM for ASUS X570

This 16 GB DDR4-3200 ECC unbuffered UDIMM runs at 1.2 V with CL22 latency and a 2Rx8 organisation. It is built for ASUS ROG Crosshair VIII Hero motherboards on the AMD X570 platform. The single 288-pin module adds error-correcting memory to a workstation or server board.

Suits builders adding ECC to a compatible ASUS

Buyers who need registered or load-reduced modules cannot use this unbuffered design. Systems that require non-ECC memory or a different DDR generation will not accept this kit. Anyone needing more than one module per slot should look at higher-density alternatives.

Fits a single UDIMM slot on the target motherboard

The module draws standard 1.2 V DDR4 power and needs no heat spreader clearance. It frees the remaining DIMM slots for future expansion while delivering ECC protection for data integrity. Installation follows the motherboard manual for the X570 platform.

Questions about this item

What motherboard slot does the 288-pin DDR4 ECC UDIMM require?

The module fits a standard DDR4 DIMM slot on the ASUS ROG Crosshair VIII Hero X570 board; no adapter or special socket is needed.

Will the 3200 MHz CL22 ECC stick run with older DDR4 modules already installed?

Yes, the system will down-clock all DIMMs to the slowest speed and loosest timings present, so the new kit operates alongside existing DDR4 memory.

How do I confirm the 16 GB 2Rx8 ECC module is detected and ECC is active after boot?

Enter the UEFI or use a tool such as dmidecode to verify 16 GB total, 2Rx8 organisation, 3200 MT/s speed and ECC enabled status.
