HX441C19PB3/8 – DDR4 SDRAM Memory Module (UDIMM) – Kingston

Kingston HyperX Predator HX441C19PB3/8 is an 8GB (1G x 64-bit) DDR4-4133 CL19 non-ECC unbuffered 288-pin desktop memory module (1Rx8, 1.35V) with Intel XMP 2.0 support. Now discontinued and available through Pacific Component Xchange.

The Kingston HyperX Predator HX441C19PB3/8 is a high-performance 8GB DDR4 desktop memory module from Kingston’s HyperX Predator line. Engineered for enthusiast gaming, overclocking, and demanding workstation builds, this single 8GB (1G x 64-bit) module delivers a factory-tested DDR4-4133 MT/s data rate at a low CAS latency of CL19 (19-23-23) when running its Intel XMP profile at 1.35V. The module ships with JEDEC-standard SPD timings of DDR4-2400 CL17-17-17 at 1.2V for guaranteed boot compatibility before XMP is enabled, and also provides a second XMP profile of DDR4-3600 CL17-18-18 at 1.35V.

Built as a single-rank (1Rx8) 288-pin non-ECC unbuffered DIMM using eight 1G x 8-bit FBGA DRAM components, the HX441C19PB3/8 pairs Kingston reliability with an aggressive aluminum heat spreader for stable high-frequency operation. As a now-discontinued part with little to no authorized-distributor stock, it is a frequent target for service, repair, and matched-kit expansion sourcing.
