8GB DDR5 4800 SODIMM module with CL40 latency and 1.1V operation for laptop upgrades
This A-Tech module provides 8GB of DDR5 memory in a 262-pin SODIMM form factor. It operates at 4800MHz with CL40 latency and a standard 1.10V voltage. The unbuffered, non-ECC design uses major brand chips for dependable performance in compatible laptops, notebooks, and all-in-one systems.
This single 8GB stick suits users adding capacity to a free slot or replacing a failed module in a system that supports DDR5 4800 SODIMM memory. Builders whose laptop requires ECC registered memory cannot use this part. Systems limited to lower speeds will downclock the module automatically, but buyers needing a 16GB kit should look elsewhere.
The 262-pin DDR5 SO-DIMM connector is the sole physical specification that determines whether this module installs in your machine. Verify your system manual lists DDR5 4800 (PC5-38400) SODIMM support before ordering, as DDR5 modules are keyed differently from earlier generations and will not seat in incompatible slots.
