4GB DDR4 2400MHz SODIMM for Laptop Upgrade

This 4GB DDR4 SODIMM module runs at 2400MHz with CL17 latency and 1.20V operation. It fits laptops, notebooks and all-in-one systems that accept 260-pin DDR4 memory. The module is unbuffered and non-ECC, matching the Micron MTA4ATF51264HZ-2G3 series specifications.

Tested Reliability and Compatibility List

Every module undergoes quality assurance testing before shipment to verify dependable performance. The part replaces six Micron part numbers including MTA4ATF51264HZ-2G3B1 and MTA4ATF5126HZ-2G3B1. Buyers should confirm their system supports DDR4 2400MHz SO-DIMM memory before ordering.

260-Pin Gold-Edge Connector and Standard Voltage

The 260-pin edge connector slots directly into standard DDR4 SODIMM sockets without adapters. Operation at 1.20V follows the DDR4 standard voltage, so no manual voltage adjustment is required. Systems limited to lower capacities or older DDR generations cannot use this module.

Questions about this item

Will the 4 GB DDR4 2400 MHz CL17 SODIMM need any firmware updates or periodic re-seating after installation?

No firmware updates or scheduled re-seating are required; the module is a standard 1.2 V unbuffered DDR4 SODIMM that runs at its rated 2400 MHz CL17 once seated in a compatible 260-pin slot.

What limit appears first when the module runs at full 2400 MHz speed continuously?

The JEDEC-defined 1.2 V voltage ceiling and CL17 latency are the fixed electrical limits; sustained operation stays within those parameters as long as the laptop’s memory controller and cooling keep the slot within normal operating temperature.

How much extra heat or fan noise does the 1.2 V DDR4 SODIMM add during all-day use?

At the standard 1.2 V DDR4 voltage the module draws minimal power, so it adds negligible heat and does not cause audible fan-speed changes in typical laptop cooling systems.
