Hynix-Compatible SODIMM Upgrade

This NEMIX RAM module provides 8GB of DDR4 memory in a 260-pin SODIMM form factor built for Hynix laptop and all-in-one platforms. It runs at 2666 MT/s with a CL19 latency and 1.2 V operating voltage. The unbuffered non-ECC design targets mainstream notebook and AIO upgrades.

Sustained-Load Behaviour

Modules are stress tested under load to verify stability during extended workloads rather than brief bursts. The 1Rx8 organisation and standard 1.20 V supply help maintain consistent throughput without additional cooling. Error-correcting circuitry is absent so data integrity relies on the host platform.

DDR4 SODIMM Interface Limits

The 260-pin DDR4 interface caps transfer rate at 2666 MT/s (PC4-21300) and voltage at 1.2 V for this module. Higher speeds or lower latencies require a different memory generation or platform support. Capacity is fixed at 8 GB per stick so systems needing more memory must populate additional slots.

Questions about this item

Does the 1.20 V module run hot or draw extra power during all-day use?

Standard DDR4 voltage of 1.20 V keeps heat and power draw low even under continuous load.

Will my Hynix laptop accept this 260-pin SODIMM without a BIOS update?

It is built to match Hynix MTA8ATF1G64HZ-2G6 systems using the 260-pin DDR4 SODIMM slot.

Can I pair this CL19 stick with existing CL19 memory in the same machine?

Matching 2666 MHz speed and CL19 latency lets it run alongside identical-spec modules without timing conflicts.
