HP HX426C16FB3/16 16GB DDR4 2666 desktop RAM

16GB DDR4 2666 Desktop Module

This HP HyperX FURY module delivers 16GB of DDR4 memory rated at 2666 MT/s with CL16 timings. It targets desktop builders who need a straightforward capacity increase for everyday workloads and gaming. The black low-profile heat spreader keeps thermals in check without adding height. Plug N Play operation at 2400 MT/s and 2666 MT/s simplifies installation on compatible platforms.

CL16 16-18-18 Timing at 1.20V

The decisive specification is the CL16 16-18-18 timing set running at the standard 1.20V DDR4 voltage. This combination determines whether the module matches the latency and voltage window your motherboard and CPU memory controller expect for stable operation at the rated 2666 MT/s data rate. Intel XMP-ready profiles are present for automatic configuration on supported Intel chipsets. Builders should verify that their platform can run DDR4 at this speed and latency before purchase.

Low-Profile Heat Spreader for Tight Builds

The updated low-profile heat spreader design frees up vertical clearance around the CPU socket, making the module compatible with larger air coolers and compact chassis where standard-height sticks would interfere. It requires a standard DDR4 DIMM slot and a motherboard that supports 2666 MT/s operation, either natively or through XMP. The single 16GB density leaves additional slots open for future expansion if the board provides them. Buyers needing ECC, registered, or laptop SO-DIMM form factors should look elsewhere.
