NEMIX RAM

NEMIX RAM 16GB DDR4 2666 ECC UDIMM 1Rx8 CL19 1.2V memory upgrade

SKU CH-V4HC-7FNGZ

16 GB DDR4 2666 ECC UDIMM module for ASUS server motherboards, CL19 latency at 1.2 V

  • Total capacity16 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL19
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • ECC protection prevents data corruption in critical workloads
  • 2666 MHz DDR4 speed delivers responsive server performance
  • 2 V operation reduces power draw and heat
  • 288-pin UDIMM fits compatible ASUS server motherboards
  • CL19 latency ensures stable timing for enterprise tasks

Server-grade ECC memory for ASUS platforms

This 16 GB DDR4 2666 module adds error-correcting capacity to compatible ASUS server motherboards such as the P11C-C/4L, P11C-M/4L, P11C-X and P11C-X/AUDIO. The unbuffered UDIMM format suits single-processor workstations and entry-level servers that require data integrity without registered DIMM overhead. IT teams specifying memory for mission-critical workloads can deploy it as a direct upgrade path.

Single-rank 1Rx8 layout with major-brand DRAM

Built on Samsung, Micron or Hynix components, the stick runs at 1.20 V with CL19 timing and carries no heat spreader, keeping the profile low for dense chassis. The 288-pin connector follows standard DDR4 UDIMM keying, so installation is a matter of aligning the notch and seating the module until the latches click. Rigorous stress testing under load is performed before shipment to confirm stability.

Replaces non-ECC or lower-capacity DDR4 UDIMMs

The jump makes sense when applications demand error detection and correction — such as virtualization hosts, ZFS-based NAS appliances or database servers — and the motherboard supports unbuffered ECC. It is not suited for systems that require registered RDIMMs, LRDIMMs or DDR5 memory, nor for boards limited to 8 GB per slot.

Questions about this item

What DDR4 standard and speed does this PC4-21300 module run at?

The module operates at DDR4 2666 MT/s, which is the PC4-21300 data rate.

What slot type and physical clearance does this 288-pin UDIMM need?

It fits a standard 288-pin DDR4 DIMM slot and has no heat spreader, so low-profile coolers clear it easily.
