8GB DDR4 SODIMM for laptop upgrades

This 260-pin module delivers 8GB of DDR4 memory at 3200MHz with a CL22 latency and 1.20V operating voltage. It is built as an unbuffered, non-ECC stick using a 1Rx8 organisation. The module serves as a direct replacement for Hynix HMA81GS6CJR8N-XN and HMA81GS6DJR8N-XN parts in compatible laptops, notebooks and all-in-one systems.

Fits standard DDR4 SODIMM slots without extra

Installation requires only an available 260-pin SO-DIMM socket and a platform that supports DDR4 3200 operation at 1.2V. The single-module design leaves additional slots free for further capacity expansion if the chassis provides them. No special cooling, firmware updates or proprietary connectors are needed beyond the standard memory interface.

Tested modules and lifetime warranty replace

Every stick undergoes quality-assurance testing before shipment to confirm reliable operation at the rated speed and latency. A lifetime warranty covers the module for as long as you own it, and US-based technical support is available before, during and after installation. These services remove the uncertainty that often accompanies generic memory purchases.

Questions about this item

Will the CL22 latency become a bottleneck during sustained heavy workloads?

CL22 is the rated CAS latency for this DDR4 3200 module; it sets the baseline access delay under any sustained load.

How much heat and power does this module draw when running all day?

It operates at the standard DDR4 voltage of 1.20 V, so power draw and heat stay within normal SO-DIMM limits for continuous use.

What must my laptop already have for this 260-pin SO-DIMM to work?

Your system needs a free DDR4 SO-DIMM slot that supports 3200 MHz (PC4-25600) unbuffered non-ECC memory.
