8 GB DDR4 2666 UDIMM for ASUS Xeon server

This 8 GB DDR4 2666 CL19 unbuffered UDIMM is built for ASUS P11C-I/NGFF2280 Mini-ITX motherboards running Intel Xeon E processors. It targets administrators upgrading a single slot in a compact server chassis where ECC is not required. The module uses major OEM Samsung, Micron or Hynix chips and runs at the standard 1.2 V.

Sustained load behaviour

Rated at PC4-21300 with CL19 latency, the stick maintains its 2666 MT/s data rate under continuous server workloads without thermal throttling because it has no heat spreader. The 1Rx8 organisation keeps signal integrity stable during long compute passes. Validation stress tests confirm error-free operation at the advertised timing for the duration of typical batch jobs.

Installation notes

The 288-pin DDR4 UDIMM inserts vertically into the single Mini-ITX DIMM slot; no tools are needed beyond opening the case. Because the board accepts only non-ECC unbuffered memory, mixing this module with registered or ECC sticks will prevent boot. The supplier label lists 2400 MHz PC4-19200 on the package, but the module itself operates at 2666 MHz as specified.

Questions about this item

Does the 1.2 V DDR4 module run hot or draw extra power under continuous server load?

The module operates at the standard 1.2 V DDR4 voltage with no heat spreader, so it relies on normal case airflow and does not add measurable heat or power draw versus other 1.2 V UDIMMs.

Will this 288-pin UDIMM work in my ASUS P11C-I/NGFF2280 Mini-ITX board with a Xeon E CPU, or do I need anything else?

It is validated for the ASUS P11C-I/NGFF2280 Mini-ITX motherboard with Intel Xeon E processors; no additional parts are required beyond an available DDR4 UDIMM slot.

Can I mix this CL19 2666 MT/s stick with my existing 2400 MT/s DDR4 modules in the same server?

The motherboard will clock all installed DDR4 to the lowest common speed, so the 2666 MT/s module will run at 2400 MT/s alongside your current sticks.
