ASUS P11C-I/NGFF2280 DDR4 2666 kit

This 64GB kit uses two 32GB DDR4 2666 UDIMMs built for the ASUS P11C-I/NGFF2280 Mini-ITX Intel Xeon E server motherboard. It targets administrators upgrading memory in that specific platform without mixing modules.

Unbuffered non-ECC 288-pin modules at 1.2V

The pair installs directly into the board's DDR4 slots using standard 288-pin UDIMM form factor. Unbuffered non-ECC design matches the platform's memory controller, leaving no need for registered or ECC DIMMs.

Samsung Micron Hynix chips tested under load

Major OEM DRAM from Samsung, Micron or Hynix is stress tested before shipping. The kit arrives as a matched 2x32GB set so the system sees identical timing and rank configuration immediately.

Questions about this item

How does the PC4-21300 rating affect sustained throughput?

The kit operates at DDR4 2666 with a PC4-21300 data rate; sustained throughput cannot exceed that bus limit.

Does the lack of a heat spreader change temperatures or noise during all-day operation?

Modules run at 1.2 V without a heat spreader; they add minimal heat and produce no noise themselves.

What motherboard slot type is required for this 288-pin UDIMM kit?

A desktop board with DDR4 288-pin UDIMM slots is needed; the kit is validated for the ASUS P11C-I/NGFF2280 Mini-ITX Xeon E motherboard.
