Corsair CMS5X16G1A56C48A2 16GB Review
Corsair Vengeance CMS5X16G1A56C48A2 16GB DDR5-5600 CL48 SODIMM laptop memory module
A 16GB DDR5 SODIMM from Corsair's Vengeance line for laptops and other small-form-factor systems, rated at 5600 MT/s CL48, 1.1V. True Latency works out to 17.1ns.
Speed and Latency
The number that matters is true latency, not CL alone. Here it is 48 / (5600 / 2) x 1000 = 17.1ns.
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. Corsair covers it with a limited lifetime warranty.
