Kingston hyper-x RGB Fury HX426C16FB3AK4/128 / RGB Fury beast KF426C16BBAK4/128 / KF426C16BB2AK4/128 , DDR4-2666 ( pc4-21300) , with asymmetrical heatsink , CL16 , 32Gb x 4 kit - support Intel XMP ( eXtreme Memory Profiles ) , 1.2v - 288pin - lifetime warranty
Another 128GB Kingston kit spanning the HyperX-to-FURY rebrand, identified across three part numbers (HX426C16FB3AK4/128, KF426C16BBAK4/128, KF426C16BB2AK4/128) for the same physical four-module set. Here the speed grade is DDR4-2666 (PC4-21300) at CL16 — 2666MT/s happens to be a common native JEDEC/server-validated speed for many Xeon and Ryzen platforms, so unlike the 3200/3466/3600 kits in this range, this one can often run closer to its full rated speed even on a system with conservative memory-overclocking support, since 2666 sits close to several platforms' default supported ceiling. Each module carries an asymmetrical low-profile heatsink with per-module RGB lighting, at a standard JEDEC 1.2V, on 288-pin DIMMs.
Even where 2666MT/s is natively supported, Intel XMP is still what guarantees CL16 timings rather than a looser JEDEC default CAS latency at the same frequency — CL16 at 2666 is a tighter, better-binned timing than the loose CL19-CL20 modules typically bundled at this speed. RGB lighting syncs via Kingston's own software or a motherboard vendor's RGB ecosystem. As a matched quad-module 128GB kit, it's intended for workstation-class capacity needs — heavy multitasking, large VMs, professional creative workloads — and is backed by Kingston's lifetime warranty. As with any 128GB four-module kit, confirming the target motherboard's QVL lists this density and speed combination is worth doing before purchase, since not every board validates the full rated speed at four-DIMM population.
