Micron 8GB DDR4 2666MHz SO-DIMM

This Micron MTA8ATF1G64HZ-2G6E1_UA module delivers 8GB of DDR4 memory at 2666MHz for laptop upgrades. It uses a 260-pin SO-DIMM form factor with a PC4-21300 bus and operates at 1.2V. The non-ECC stick is rated CL19 and organised as a single 1Rx8 rank.

Suits laptops accepting DDR4 SO-DIMMs at 2666MHz

Buyers whose systems require ECC memory or a different voltage should look elsewhere. The module is sold without cables, manuals or other accessories. Compatibility depends on matching the exact part number to the original component.

Single-rank 1Rx8 organisation at CL19

The 1Rx8 rank configuration and CL19 latency are the key specifications that determine whether this module matches the laptop's memory controller requirements. Verify the original part number against the compatible list including 937236-850 and KN8GB04028 before ordering.

Questions about this item

How do I install the 260-pin SO-DIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly at both ends until the side clips click shut, then verify the laptop reports the full 8GB capacity in BIOS.

What maintenance or replacement will this DDR4 module need over time?

No routine maintenance is required; keep the contacts clean and ensure the laptop cooling vents stay clear so the 1.2V module operates within its thermal limits.

What limit appears first during sustained heavy workloads on this CL19 memory?

The CAS latency of 19 cycles at 2666MHz sets the response ceiling; bandwidth scales with the PC4-21300 rating but latency remains the primary bottleneck.
