Compatible 16GB DDR4 Module

This 16GB DDR4 2133MHz CL15 module is built as a compatible replacement for the Corsair CMK32GX4M2A2133C13 kit. It runs at the standard 1.20V DDR4 voltage and uses an unbuffered non-ECC design. The single DIMM targets desktop owners who need a straightforward capacity increase.

Verify DDR4 DIMM Slot and Speed Support

Confirm that your motherboard accepts DDR4 288-pin DIMMs and can operate memory at 2133MHz. Check the board manual for maximum per-slot capacity and whether it requires specific rank configurations such as 2Rx8. Ensure the BIOS is current enough to recognise the module at its rated CL15 timing.

Suits Standard Desktop Upgrades Not Laptops

This module suits typical desktop towers and workstations that use regular DDR4 DIMM slots and do not demand ECC or registered memory. It will not fit laptops or small-form-factor boards that require SO-DIMMs. Systems needing ECC error correction or quad-channel kits should look at different parts.

Questions about this item

Will this single 16 GB module work in a motherboard that only supports 8 GB per slot?

The module is 16 GB; if your board limits each slot to 8 GB it will not be recognised. Check the motherboard manual for the maximum capacity per DIMM before buying.

My board lists DDR4-2133 CL13 — is CL15 compatible?

Yes. The memory will run at the motherboard's default settings, typically 2133 MHz with the looser CL15 timing, which is fully compatible.

Does the 262-pin figure mean this is a laptop SODIMM?

No. The physical module is a 288-pin desktop DIMM; the 262-pin reference in some data is an error. It fits standard desktop DDR4 slots only.
