64GB DDR5 SODIMM kit for select systems

This kit provides two 32GB DDR5-4800 SODIMM modules, totalling 64GB of non-ECC unbuffered memory. Each module runs at 1.1V with CAS latency 40 and 2Rx8 organisation. The parts use major-brand chipsets and a 288-pin layout.

Suited for matched-pair upgrades on compatible

The kit targets users whose system accepts DDR5 SODIMM memory at 4800MHz and benefits from a matched pair for maximum throughput. It does not suit platforms that require ECC, registered modules, or a different pin count. Buyers needing a single module or a different capacity should look elsewhere.

DDR5-4800 speed with CL40 timing

The decisive specification is the DDR5-4800 (PC5-38400) rating combined with 40-40-40-96 timings. If the platform cannot operate at this speed or latency, the modules will downclock to the slowest installed component. Verify the system supports DDR5 SODIMM at 4800MHz before purchase.

Questions about this item

Does the 288-pin SODIMM fit my laptop's DDR5 slot?

These modules use the standard 288-pin DDR5 SODIMM form factor; they fit any laptop or mini-PC slot wired for DDR5 memory.

Do I need to change any BIOS settings when installing the 2Rx8 4800MHz kit?

Install the pair in the two slots, power on, and the system will train at 4800 MHz 40-40-40-96 automatically; the step people miss is seating both sticks fully until the latches click.

When should I expect to replace the 1.1V DDR5 modules?

The modules carry a limited lifetime warranty against manufacturing defects; under normal use they last the usable life of the system and rarely need replacement.
