What this module is and who it fits

This A-Tech module is an 8GB DDR4 SO-DIMM built as a direct replacement for the PNY MN8GSD42666 part. It runs at 2666MHz with CL19 latency at the standard 1.20V and uses a 260-pin unbuffered, non-ECC layout. The stick is designed for laptops, notebooks and all-in-one systems that accept DDR4 SO-DIMM memory.

Who should buy it and who should not

Buyers needing a single 8GB DDR4 2666MHz SODIMM to replace a failed PNY module or to add capacity to a compatible slot will find this part matches the factory specifications. Systems that require ECC, registered memory, a different voltage, a different pin count, or a speed other than 2666MHz cannot use this module.

The specification that decides fit

The module is a 260-pin DDR4 SO-DIMM operating at 2666MHz (PC4-21300) with CL19 timing at 1.20V in a 1Rx8 unbuffered, non-ECC configuration. If your laptop's memory slot and BIOS support this exact combination, the part will work; otherwise it will not seat or post.

Questions about this item

Will this 260-pin DDR4 SODIMM fit the same slot as the original PNY MN8GSD42666 module?

Yes, it matches the 260-pin DDR4 SO-DIMM form factor and is specified as a compatible replacement for the PNY MN8GSD42666.

If I install this CL19 module alongside an existing stick, will the system run both at the slower latency?

The system will operate all installed modules at the lowest common speed and latency, so this CL19 stick will run at whatever timing the slowest module requires.

How can I confirm the new 8GB module is recognised at 2666 MHz after installation?

Check the memory speed in Task Manager's Performance tab or run CPU-Z to verify the module reports DDR4-2666 (PC4-21300) and the full 8GB capacity.
