A-Tech 16GB RAM Replacement for CT16G48C40S5 | DDR5 4800MHz PC5-38400 CL40 SODIMM 1Rx8 1.1V Non-ECC SO-DIMM 262-Pin Laptop, Notebook Memory Module
Available Styles / Variations:
Slow JEDEC Baseline (Not Recommended)
Validated by C.R. Vinoth Kumar · Founder & Senior Editor
This kit runs at loose JEDEC default timings (CL40 or slower). CL40/CL48 speeds indicate lower-binned DRAM chips which create a severe latency bottleneck, reducing CPU frame pacing and game performance by up to 10-15% compared to optimized kits.
