Corsair ValueSelect 4GB (1x4GB) DDR4 2133MHz CL15 SODIMM Laptop Memory

Corsair ValueSelect 4GB is a laptop memory module — a DDR4 SODIMM — for notebooks that have a free memory slot or a single small stick already fitted. It is the plain, no-frills route to more RAM in a machine that has started to feel tight. The module runs at DDR4-2133MHz (PC4-17000) with CAS timings of 15-15-15-36 at 1.2V, the JEDEC standard for DDR4 notebook memory, so it is recognised and runs at its rated speed with no BIOS tuning. The form factor is the standard 260-pin SODIMM used by mainstream laptops and small-form-factor systems, and it is compatible with Intel 100/200/300/400/500-series platforms. Corsair covers ValueSelect memory with a limited lifetime warranty. This is the upgrade for a student or office laptop that swaps to disk the moment a browser, a spreadsheet and a video call are open together. Fitting it is a matter of one panel screw and one slot on most machines, and because it is a single module you can pair it with an existing stick of the same capacity or start a two-module set and add the second later.
