16GB DDR5 4800MHz SODIMM module

This 16GB DDR5 SO-DIMM runs at 4800MHz with a CAS latency of 40 and operates at 1.10V. It is an unbuffered, non-ECC module built with 1Rx8 organisation and 262-pin form factor for laptop, notebook and all-in-one systems.

DDR5 4800 speed and voltage limits

The DDR5 4800 (PC5-38400) standard sets the data rate and the 1.1V operating voltage for this module. Systems that only support earlier DDR generations cannot use this memory because the notch position and signalling are different. The module has no heat spreader, so airflow in the chassis contributes to thermal management.

Check your laptop before ordering

Verify that your device accepts 262-pin DDR5 SO-DIMMs and that the firmware supports 4800MHz operation at 1.1V. Confirm the maximum capacity per slot and the total number of slots available in your model. This module is listed as a compatible replacement for HP/HPE part numbers M49879-001 and 5S4C4UT.

Questions about this item

Is the single 16GB module enough, or should I buy two for dual-channel?

The kit contains one 16GB stick; adding a second identical module enables dual-channel bandwidth on platforms that support it.

Will the 4800MHz rating actually run at that speed in my laptop?

The module is rated DDR5 4800 (PC5-38400) with CL40 at 1.10V; the system BIOS will set the highest common speed supported by the CPU and chipset.

What does the 262-pin DDR5 SO-DIMM interface limit in practice?

The 262-pin DDR5 SO-DIMM form factor fits only DDR5 laptop slots and caps transfer rate to the DDR5 4800 standard.
