ASUS Server DDR4 ECC Kit

This 64 GB kit contains two 32 GB unbuffered UDIMMs built for ASUS server motherboards such as the P11C-C/4L, P11C-M/4L, P11C-X and P11C-X/AUDIO. It targets administrators who need ECC protection on platforms that accept standard DDR4 2666 modules.

288-Pin UDIMM Build

Each module uses a 288-pin layout without a heat spreader, keeping the profile low for dense server chassis. Major OEM chips from Samsung, Micron or Hynix run at 1.2 V with a CL19 latency and 2Rx8 organisation for stable operation under load.

DDR4 2666 Upgrade Path

The kit replaces lower-capacity or non-ECC DDR4 DIMMs on compatible ASUS boards, adding error correction and doubling density per slot. The jump is worthwhile when workloads demand data integrity and the platform supports unbuffered ECC at this speed.

Questions about this item

What DDR4 speed and peak bandwidth does this 64GB kit run at?

The modules operate at 2666 MT/s, which corresponds to a PC4-21300 data rate.

What physical slot and module height clearance do these 32GB sticks require?

They use the standard 288-pin UDIMM form factor with no heat spreader, so they fit any DDR4 UDIMM slot without extra height concerns.

Which way do the notches align when seating these ECC UDIMMs in an ASUS server board?

Match the off-centre notch on each 288-pin module to the key in the slot, press straight down until both side clips click, and populate the channels per the motherboard manual for dual-channel operation.
