Crucial 8GB DDR5 RAM, 4800MHz CL40 High-Speed Laptop RAM, SODIMM 262-Pin - CT8G48C40S5
Slow JEDEC Baseline (Not Recommended)
Validated by C.R. Vinoth Kumar ยท 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.
