Corsair CMS5X16G1A48C40A2-PCS 16GB Review

Corsair Vengeance CMS5X16G1A48C40A2-PCS 16GB DDR5-4800 CL40 SODIMM laptop memory module

A 16GB DDR5 SODIMM from Corsair's Vengeance line for laptops and other small-form-factor systems, running at the JEDEC-standard 4800 MT/s with CL40 timings (40-40-40-77) at 1.1V.

Speed and Latency

True latency is CAS latency divided by half the transfer rate: 40 / (4800 / 2) x 1000 = 16.7ns. The full timings are 40-40-40-77, with tRCD and tRP matching the CAS latency.

Platform Fit

This is a DDR5 SODIMM for laptops and mini PCs with replaceable memory slots. It does not fit desktop boards, and it cannot go into laptops with soldered memory.

Capacity and Configuration

This is a single 16GB module. On its own it runs in single-channel mode; pair it with an identical module for dual-channel bandwidth. 16GB covers everyday use and lighter gaming, but recent games and browsers can fill it.
