About This Product
The Kingston HX321LS11IB2/4 is a single 4GB DDR3L-2133 SODIMM module with a CAS Latency of 11. This memory is suitable for older laptops or small form factor PCs that require DDR3L memory and can benefit from a higher clock speed than standard DDR3-1600. Its 10.31ns first word latency and 17.1 GB/s theoretical bandwidth offer a modest performance improvement over slower DDR3 modules, but its single-module configuration limits dual-channel performance.
Verdict
“Good for upgrading older DDR3L laptops needing a single, faster 4GB module.”
