64 GB DDR5 SODIMM kit for laptops and NAS

This dual-channel kit delivers 64 GB of DDR5 memory across two 32 GB modules. It is built for laptops, all-in-one systems and compatible NAS devices that accept 262-pin SO-DIMMs. The JEDEC-standard 4800 MT/s speed and 1.1 V operation suit mainstream platforms without overclocking.

Standard-height modules with no heat spreader

The unbuffered, non-ECC sticks use a plain green PCB that fits tight SODIMM slots in thin-and-light notebooks. Dual-rank 2Rx8 organisation helps bandwidth on dual-channel boards while keeping the physical profile low enough for cramped chassis. No extra clearance is needed beyond the slot itself.

4800 MT/s CL40 at 1.1 V decides compatibility

The single spec that determines fit is the JEDEC DDR5 4800 CL40 1.1 V rating; systems that require a different voltage, speed bin or latency will not run these modules correctly. Buyers whose firmware demands XMP profiles, ECC, registered DIMMs or a lower CAS value must choose a different kit.

Questions about this item

Does DDR5 4800 CL40 run at its rated speed on a laptop that only supports 4800 MT/s?

Yes, the modules are JEDEC-standard DDR5 4800 PC5-38400 CL40 and will operate at 4800 MT/s on any system that supports that speed.

Will the 262-pin SO-DIMM form factor fit my laptop's memory slots?

The kit uses standard 262-pin DDR5 SO-DIMMs, the correct physical format for laptops, all-in-ones and NAS units that accept DDR5 memory.

Is any BIOS change needed when installing these 1.1 V unbuffered modules?

No, they are 1.1 V non-ECC unbuffered DIMMs that work at default JEDEC settings; just seat each module firmly until the retention clips click.
