HX318LS11IB/4 – DDR3L SDRAM SO-DIMM – Kingston

Kingston HX318LS11IB/4 is a HyperX Impact 4GB (512M x 64-bit) DDR3L-1866 CL11 1.35V low-voltage 204-pin SO-DIMM laptop memory module. Now obsolete and hard to find; available through Pacific Component Xchange by RFQ.

The Kingston HX318LS11IB/4 is a HyperX Impact 4GB (512M x 64-bit) DDR3L-1866 unbuffered, non-ECC SO-DIMM memory module designed for high-performance notebooks and small form factor systems. Built on a single-rank (1Rx8) design using eight 512M x 8-bit DDR3 FBGA components, this module delivers DDR3L-1866 performance at a low-latency timing of 11-11-11 while operating at either 1.35V or 1.5V for dual-voltage flexibility and reduced power consumption. The HyperX Impact line has since been rebranded as Kingston FURY Impact, with the direct successor part being KF318LS11IB/4.
