8GB DDR4 2666MHz SODIMM for Lenovo Laptops

This 8GB DDR4 SO-DIMM runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 260-pin form factor and unbuffered, non-ECC architecture built with major brand chips. The module is a compatible replacement for IBM-Lenovo part numbers including 01AG812, 01AG824, 01AG841, 01AG843, 01AG853, 01AG854, 01AG855, 01AG864, 4X70R38790 and 4X70W30750.

Suits owners of listed Lenovo laptops needing

This module fits systems that accept a single 260-pin DDR4 2666MHz SO-DIMM without ECC or registered buffering. It is not for machines that require ECC memory, registered DIMMs, a different pin count, or a different DDR generation. Buyers whose laptops need a higher-density single module or a different voltage should look elsewhere.

260-pin DDR4 SO-DIMM form factor

The 260-pin DDR4 SO-DIMM form factor is the single specification that determines whether this module physically installs and electrically functions in the target laptop. Verify that the service manual for the specific Lenovo model lists a 260-pin DDR4 SO-DIMM slot before ordering.
