What this module is

This is an A-Tech 8 GB DDR4 3200 MHz SODIMM built as a compatible replacement for Micron part numbers MTA4ATF1G64HZ-3G2, MTA4ATF1G64HZ-3G2B2 and MTA4ATF1G64HZ-3G2F1. It uses a 260-pin unbuffered non-ECC layout at 1.20 V standard voltage. The module carries CL22 latency and PC4-25600 bandwidth rating.

Who this suits and who should look elsewhere

It suits owners of laptops, notebooks or all-in-one PCs that accept a single 8 GB DDR4 SODIMM at 3200 MHz with CL22 timing. Builders who need ECC registered memory, a different pin count, a higher capacity per slot or a lower CAS latency should look elsewhere. Systems limited to slower DDR4 speeds will still run the module but at the lower rated frequency.

Deciding specification: DDR4 3200 MHz CL22 SODIMM

The single specification that decides fitment is the DDR4 3200 MHz CL22 260-pin SODIMM profile. Your system must support DDR4 SO-DIMM memory at this speed and latency with non-ECC unbuffered operation. Verify the motherboard or laptop documentation for exact compatibility before purchase.

Questions about this item

Does the CL22 latency limit bandwidth when the laptop runs memory-heavy tasks for hours?

The module runs at DDR4 3200 with CL22 timing; latency stays constant under sustained load, and the 1.2 V rating keeps power draw within the DDR4 standard envelope.

Will the stick run hot or noisy inside a thin-and-light chassis during all-day use?

No heat spreader is fitted, but the 1.20 V unbuffered DDR4 design produces minimal heat and has no moving parts, so it stays silent and cool in typical laptop airflow.

My laptop only has one free SODIMM slot — is that enough for this 8 GB module?

Yes, the kit is a single 260-pin DDR4 SO-DIMM, so one empty slot that supports DDR4 3200 non-ECC memory is all that is required.
