64 GB DDR4 ECC UDIMM kit

This 64 GB kit contains four 16 GB DDR4 2666 PC4-21300 ECC UDIMM modules. It runs at 1.2 V with CL19 latency and uses a 288-pin unbuffered design. The kit is built for ASUS server motherboards including the P11C-C/4L, P11C-M/4L, P11C-X and P11C-X/AUDIO models.

Suited for ECC server upgrades

System administrators expanding compatible ASUS server platforms will appreciate the validated compatibility and error-correcting capability. Builders needing non-ECC memory, registered DIMMs, higher speeds or different pin layouts should look at other memory types.

Four-module capacity and headroom

The 64 GB total across four slots handles virtualisation workloads, database caching and multi-threaded server tasks comfortably. Workloads that demand registered memory, speeds above 2666 MT/s or capacities beyond 64 GB will exceed this kit's specification.

Questions about this item

Do I need four free 288-pin DDR4 slots on my ASUS server motherboard to install this 64GB kit?

Yes, the kit contains four 16GB UDIMMs and each one occupies a single 288-pin DDR4 slot on the board.

Can I mix these CL19 2666 MT/s ECC modules with slower DDR4 ECC sticks I already have?

The system will run all modules at the speed and timings of the slowest installed kit, so older CL19 or higher-latency sticks will work but limit overall throughput.

How do I confirm the full 64GB is recognised and ECC is active after installation?

Check the BIOS memory summary for 64GB total and ECC enabled, then verify in the OS with a tool that reports ECC status such as dmidecode or CPU-Z.
