ASUS Server DDR4 ECC Kit

This 32 GB kit contains two 16 GB DDR4 2666 ECC unbuffered UDIMMs built for ASUS server motherboards. Each module runs at 1.2 V with CL19 latency and a 1Rx8 organisation. The 288-pin DIMMs use major OEM chips from Samsung, Micron or Hynix and are sold new.

Upgrade from non-ECC or lower capacity

Replacing standard unbuffered memory without error correction adds data-integrity protection for workloads that cannot tolerate silent corruption. Moving from a 16 GB or 8 GB configuration to this 32 GB dual-channel kit doubles usable memory bandwidth for supported boards. The jump is worth it when the motherboard requires ECC unbuffered UDIMMs and the platform supports DDR4 2666 speeds.

Suits ASUS P11C-C/4L, P11C-M/4L.

Builders populating these specific ASUS server boards with validated ECC modules will gain stable operation. Systems that need registered or load-reduced DIMMs, DDR5 memory, or higher frequencies than 2666 MT/s should look at something else. Buyers without ECC-capable chipsets cannot use the error-correction feature.

Questions about this item

Will the 288-pin DDR4 modules fit my ASUS P11C-C/4L server board?

Yes, the kit is built for ASUS server motherboards including the P11C-C/4L, P11C-M/4L, P11C-X and P11C-X/AUDIO and uses the standard 288-pin DDR4 UDIMM form factor.

Do I need to change any BIOS settings when installing this ECC UDIMM kit?

Install the two 16 GB modules in the slots recommended by the ASUS manual, then enable ECC in the BIOS so the 1Rx8 chips can correct single-bit errors.

How long will the Samsung, Micron or Hynix chips last before they need replacement?

The modules are stress-tested under load and carry a lifetime replacement warranty, so they are expected to remain in service for the life of the server.
