What this module is

This is a 4 GB DDR4 SODIMM built for laptop, notebook and all-in-one systems. It runs at 2133 MHz with CL15 timing and 1.2 V standard voltage. The 260-pin unbuffered design fits mainstream mobile platforms that accept PC4-17000 memory.

Who it fits and who it does not

It suits owners replacing a Micron MTA8ATF51264HZ-2G1 series module or adding a single 4 GB stick to a compatible slot. Buyers who need ECC error correction, registered buffering, higher capacity per module or faster speeds should look at other memory options.

Behaviour under sustained load

The module operates at standard DDR4 voltage and passes quality assurance testing for dependable operation. Unbuffered non-ECC memory of this specification maintains stable throughput during extended multitasking sessions without thermal throttling or voltage drift.

Questions about this item

Does my laptop need a free 260-pin DDR4 SO-DIMM slot to use this 4 GB module?

Yes, the module is a 260-pin DDR4 SO-DIMM and requires an empty DDR4 SO-DIMM slot in the laptop.

Will this CL15 2133 MHz module run at its rated speed alongside an existing DDR4 2133 MHz stick?

Both modules will operate at DDR4 2133 MHz (PC4-17000) with CL15 timing when installed together.

How can I confirm the new RAM is detected at 2133 MHz with CL15 timing after installation?

Check the memory speed and CAS latency in the BIOS or with a tool such as CPU-Z; it should show 2133 MHz and CL15.
