8GB DDR4 2666MHz Desktop Module

This A-Tech module provides 8GB of DDR4 memory at 2666MHz with CL19 latency and 1.20V operation. It is an unbuffered, non-ECC DIMM built with major brand chipsets and designed as a direct replacement for the Corsair CMK8GX4M1A2666C16. The 288-pin form factor fits standard desktop slots.

Replaces Corsair CMK8GX4M1A2666C16

This module serves as a compatible equivalent for the Corsair CMK8GX4M1A2666C16, matching the 2666MHz speed and 1.2V voltage. The jump is worth it when your system requires a CL19 timing module and you need a tested, reliable replacement without a heat spreader. Verify your motherboard supports this frequency and timing before purchasing.

Suits standard desktop upgrades

This memory suits users upgrading a desktop that specifically accepts DDR4 2666MHz CL19 unbuffered DIMMs. It is not intended for systems requiring ECC, registered modules, lower latency timings, or higher voltage operation. Buyers needing heat spreaders, different capacities, or other DDR generations should look elsewhere.

商品問答

Will the 288-pin DDR4 DIMM fit a standard desktop motherboard slot?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor that fits any desktop board with a DDR4 slot.

What is the correct way to seat the module so the motherboard recognises the full 8GB capacity?

Align the notch with the slot key, press down firmly until both side clips click shut, then verify 2666 MHz operation in the BIOS.

Does the lack of a heat spreader mean the chips need active cooling or periodic replacement?

No, the 1.2V DDR4 chips run cool enough for normal desktop use; no extra cooling or scheduled replacement is required.
