Compatible 16GB DDR5 SO-DIMM

This 16GB DDR5 module replaces Hynix HMCG78AEBSA and HMCG78MEBSA parts in laptops, notebooks and all-in-one PCs. It runs at 4800MHz with CL40 latency and standard 1.10V DDR5 voltage. The unbuffered, non-ECC design fits 262-pin SO-DIMM slots without extra configuration.

Sustained workload behaviour

Rated at 4800MHz PC5-38400, the module maintains its rated speed under continuous multi-tasking and heavy application loads. Standard DDR5 voltage keeps power draw predictable during extended sessions. Quality assurance testing verifies stability for prolonged use.

Physical fit and daily use

The bare 262-pin SO-DIMM has no heat spreader, so it slides into tight laptop sockets without clearance issues. Unbuffered, non-ECC layout matches factory memory for direct replacement. Verify your system supports DDR5 SO-DIMM before ordering.

Questions about this item

How much heat and power does the 16GB DDR5 4800MHz CL40 module draw when running continuously?

It operates at the standard DDR5 voltage of 1.1V with no heat spreader, so thermal output stays low during all-day workloads.

What must my laptop already have to accept this 262-pin SODIMM?

Your system needs a DDR5-compatible SO-DIMM slot and a memory controller that supports 4800 MT/s at CL40 latency.

Will this 1Rx8 unbuffered stick work alongside an existing Hynix HMCG78AEBSA module?

Yes, it is built as a direct compatible replacement for both HMCG78AEBSA and HMCG78MEBSA part numbers.
