Replacement for Corsair CMK16GX4M2A2133C13

This A-Tech desktop memory module delivers 8GB of DDR4 2133 speed with CL15 latency. It is an unbuffered, non-ECC DIMM built to match the original Corsair part number. The 1.20V voltage aligns with standard DDR4 specifications. System builders can use it as a direct drop-in upgrade for compatible platforms.

Suitable for DDR4 desktop upgrades needing 8GB

Users replacing a failed Corsair CMK16GX4M2A2133C13 stick or adding capacity to a board that supports DDR4 2133 will find this module appropriate. Systems requiring ECC, registered memory, lower latency than CL15, or a different DDR generation should look elsewhere. Verify motherboard qualification lists before ordering.

CL15 CAS latency at DDR4 2133 sets the timing

The module operates at CL15 latency with a tested frequency of 2133MHz and PC4-17000 rating. This timing figure determines whether the memory meets your board's supported latency window. Match this value against your system specifications to confirm compatibility.

Questions about this item

Should I pick the single 8 GB module or the 16 GB kit that the Corsair part number represents?

This listing is a single 8 GB DIMM; the Corsair CMK16GX4M2A2133C13 is a 16 GB kit containing two 8 GB sticks, so order two of these if you need the full kit capacity.

Will the CL15 timing at 2133 MHz actually run at that speed in my desktop?

The module is rated DDR4 2133 CL15 at 1.20 V; most motherboards will default to JEDEC 2133 MHz with CL15 automatically, and you can confirm the profile in BIOS if needed.

Does the 288-pin DDR4 DIMM fit the standard desktop slot and what bandwidth does PC4-17000 provide?

Yes, it uses the standard 288-pin DDR4 DIMM form factor, and PC4-17000 indicates a peak transfer rate of 17 GB/s on a compatible platform.
