Kingston FURY Impact 32GB DDR5 SO-DIMM

This Kingston FURY Impact module delivers 32GB of DDR5 memory in a 262-pin SO-DIMM form factor. It operates at 5600 MT/s with a CAS latency of CL40 and a voltage of 1.10V. The module is designed for laptop upgrades and high-performance mobile computing.

Suits AMD Ryzen and Intel compatible notebooks

This single 32GB stick fits laptops with a free DDR5 SO-DIMM slot supporting the rated speed and voltage. Buyers needing ECC error correction or lower latency timings should look at alternative modules. Systems requiring a matched pair for dual-channel performance will need a second identical unit.

Capacity: 32GB single module

The 32GB density determines whether this part matches the maximum supported memory per slot for a specific laptop. Verify the device manufacturer's qualified vendor list before purchase. This capacity also defines the total memory added when installing one stick into an available slot.

Questions about this item

Should I choose the 32 GB DDR5 5600 CL40 module or look for a different capacity or speed?

This module provides a single 32 GB stick at DDR5 5600 with CL40 timings; choose it if your laptop has one free SO-DIMM slot and you want the full 32 GB in one slot, otherwise select a lower-capacity kit that matches your slot count.

What does the DDR5 5600 (PC5 44800) rating deliver in a real laptop?

The 5600 MT/s transfer rate and CL40 latency give high bandwidth and responsive multitasking for gaming and heavy workloads, running at the standard 1.10 V DDR5 voltage.

Does the 262-pin DDR5 SO-DIMM interface limit performance or compatibility?

The 262-pin DDR5 SO-DIMM form factor is the current laptop standard; it caps speed at the module's rated 5600 MT/s and works with AMD Ryzen and Intel platforms that support DDR5 SO-DIMM memory.
