DESCRIPTION
HyperX HX321LS11IB2/4 is a 512M x 64-bit (4GB) DDR3L-2133
CL11 SDRAM (Synchronous DRAM) 1Rx8, low voltage, memory
modules, based on eight 512M x 8-bit DDR3 FBGA compo-
nents. This module has been tested to run at DDR3L-2133 at a
low latency timing of 11-12-13 at 1.35V or 1.5V. Additional
timing parameters are shown in the PnP Timing Parameters
section below. The JEDEC standard electrical and mechanical
specifications are as follows:

All Kingston products are tested to meet our published specifications. Some motherboards or system configurations may not operate at
the published HyperX memory speeds and timing settings. Kingston does not recommend that any user attempt to run their computers
faster than the published speed. Overclocking or modifying your system timing may result in damage to computer components.
