32GB DDR5 4800 SO-DIMM

This 32 GB DDR5 4800 MHz SO-DIMM module delivers a direct memory upgrade for compatible laptops and all-in-one systems. It operates at PC5-38400 speed with a CAS latency of 40 and runs at the standard 1.10 V DDR5 voltage. The unbuffered, non-ECC design uses major-brand DRAM ICs and fits 262-pin slots. Quality assurance testing ensures dependable performance for everyday workloads.

Suits single-slot 32GB upgrades.

This module targets users replacing a Micron MTC16C2085S1SC48BAX part or adding 32 GB in a single SO-DIMM slot. It is unsuitable for systems that require ECC error correction or registered buffering. Builders needing higher total capacity across multiple slots or lower-latency timings should verify platform limits before purchasing.

4800 MHz DDR5 speed rating

The decisive specification is the DDR5 4800 (PC5-38400) speed grade paired with 2Rx8 organization. This rating determines whether the module matches the memory controller's supported data rate and rank configuration. Confirm the laptop's qualified vendor list accepts this exact speed and rank to avoid compatibility issues.

Questions about this item

What does the 4800MHz speed actually deliver in a laptop?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, giving higher bandwidth than older standards for faster load times and smoother multitasking.

How does the DDR5 SO-DIMM interface affect compatibility?

It uses the 262-pin DDR5 SO-DIMM form factor with unbuffered, non-ECC operation, so it fits only laptops that support DDR5 SO-DIMM memory.

What physical space and power does the 32GB module need?

A single 262-pin SO-DIMM slot and 1.10V supply; the stick has no heat spreader and uses 2Rx8 major-brand DRAM ICs.
