HX426C13PB3/8 – 8GB DDR4 SDRAM Memory Module (UDIMM) – Kingston

The HX426C13PB3/8 is a Kingston HyperX Predator 8GB DDR4 SDRAM unbuffered non-ECC memory module, rated for DDR4-2666 CL13-15-15 at 1.35V via Intel XMP 2.0 on a 288-pin DIMM.

The Kingston HX426C13PB3/8 is an 8GB DDR4 SDRAM unbuffered, non-ECC memory module from the HyperX Predator family. Built on eight 1G x 8-bit FBGA components, it is organized as 1G x 64-bit, single-rank (1Rx8), on a standard 288-pin DIMM form factor. The module is factory-tested and pre-profiled for high-performance desktop use, delivering DDR4-2666 at a low CAS latency of CL13-15-15 at 1.35V through Intel Extreme Memory Profile (Intel XMP) 2.0, while defaulting to a JEDEC-standard DDR4-2400 (CL17) profile at 1.2V for guaranteed plug-and-play compatibility.

An aluminum heat spreader (overall module height 42.20 mm / 1.661 in) provides thermal headroom for sustained performance. The HX426C13PB3/8 is now discontinued/obsolete and is no longer offered through authorized distribution, making it a hard-to-find part for repair, upgrade, and end-of-life system maintenance.
