DDR5 SODIMM for Laptop Upgrade

This A-Tech module delivers 16GB of DDR5 memory at 4800MHz with a CAS latency of 40. It uses a 262-pin SO-DIMM form factor and operates at the standard 1.10V voltage. The unbuffered, non-ECC design relies on major-brand DRAM ICs for dependable operation in compatible notebooks and all-in-one systems.

Suits Single-Slot 16GB DDR5 Requirements

Buyers needing a direct replacement for the Hynix HMCG78AEBSA095N part number will find this module matches the 1Rx8 rank structure and PC5-38400 rating. Systems that require ECC error correction, registered buffering, or a different pin count should look at other memory types. The lack of a heat spreader keeps the profile low for tight chassis spaces.

262-Pin DDR5 Interface Decides Fit

The 262-pin DDR5 SO-DIMM interface is the single specification that determines whether this module installs in a given laptop. Only platforms built for DDR5 SO-DIMM slots can accept it; the notch position and electrical signalling differ from earlier memory generations. Verify the system manual specifies DDR5 SO-DIMM support before purchase.

Questions about this item

Does DDR5-4800 PC5-38400 run at 4800 MT/s on a laptop that only supports 4800?

Yes — the module is rated DDR5 4800 (PC5-38400) and will operate at 4800 MT/s when the platform supports that speed.

Will a 262-pin DDR5 SO-DIMM fit my laptop's memory slot?

The stick uses the standard 262-pin DDR5 SO-DIMM form factor, so it fits any laptop slot built for DDR5 SO-DIMMs.

How do I seat the module correctly and what step do people miss?

Insert the module at the proper angle until the gold contacts disappear, then press down firmly until both side clips click — the click is the step many skip.
