HX421S13IB/4 – DDR4 SDRAM SODIMM – Kingston
Kingston HX421S13IB/4 is a 4GB (512M x 64-bit) DDR4-2133 CL13 non-ECC unbuffered 260-pin SODIMM from the HyperX Impact line, designed for slim notebooks and small-form-factor systems. This discontinued module is available now for RFQ.
The Kingston HX421S13IB/4 is a 4GB (512M x 64-bit) DDR4-2133 (PC4-17000) laptop memory module from Kingston’s HyperX Impact family. It is a single-rank (1Rx8) 260-pin SODIMM built on eight 512M x 8-bit DDR4 FBGA components, operating at a low 1.2V with a tested low-latency timing of CL13 (13-13-13). The module is non-ECC and unbuffered, and supports Intel Extreme Memory Profile (XMP) 2.0 for simple, profile-based tuning.
Engineered for slim and ultra-slim notebooks as well as compact systems, HyperX Impact DDR4 combines a low-profile form factor with reduced power draw for cooler operation and improved battery efficiency. The HX421S13IB/4 is now discontinued by the manufacturer, making it a hard-to-find part for repair, upgrade, and legacy-platform builds.
