OWC 128GB (4x32GB) DDR5 4800 PC5-38400 CL40 2Rx8 288-pin 1.1V Non-ECC UDIMM Memory RAM Module Upgrade Kit for Select Desktops
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.
