Capacity and fit

This kit supplies 128GB of DDR5 memory across four 32GB modules built for 262-pin SODIMM slots. It targets laptops, all-in-one PCs and compatible NAS units that accept unbuffered ECC memory running at 1.1V.

Build and connectors

Each stick follows the JEDEC-standard 262-pin layout with no heat spreader, keeping the profile thin for tight chassis. The unbuffered ECC design plugs directly into standard SODIMM sockets, so installation is a straightforward DIY task on supported systems.

DDR5 practical limits

DDR5 at 5600MT/s with CL46 latency delivers the baseline bandwidth the JEDEC spec defines for this speed grade. Actual throughput depends on the host platform’s memory controller and whether it can run all four ranks at the rated frequency without downclocking.

Questions about this item

What does the DDR5 5600 PC5-44800 rating mean for real-world speed?

The modules run at 5600 MT/s with a PC5-44800 bandwidth rating and CL46 latency, delivering JEDEC-standard DDR5 performance for compatible laptops and all-in-one systems.

Will these 262-pin SODIMMs fit my laptop's memory slots?

Each stick uses the standard 262-pin DDR5 SO-DIMM form factor, so they install in any laptop or all-in-one that accepts DDR5 SO-DIMMs and supports 32 GB per slot.

How do I install the four 32 GB modules correctly?

Power off, open the memory compartment, align each module's notch with the slot key, press firmly until the side clips click, then verify 128 GB appears in BIOS or system settings.
