A-Tech 64GB DDR5 5200MHz SODIMM Kit

This A-Tech kit provides 64GB of DDR5 laptop memory as two 32GB modules. It runs at 5200MHz with CL42 latency at the standard 1.1V. The unbuffered, non-ECC SO-DIMMs use major-brand DRAM ICs and are designed for compatible laptops, notebooks, and all-in-one computers.

Suits DDR5 systems needing 64GB dual-channel

Builders upgrading a DDR5-capable laptop or all-in-one that accepts 262-pin SO-DIMMs will gain 64GB in a matched pair. Systems limited to a single memory slot, those requiring registered or ECC modules, or platforms that do not support DDR5 cannot use this kit.

Dual-channel 2x32GB layout at CL42

The kit delivers 64GB total across two 32GB modules for dual-channel operation. Verify your system supports DDR5-5200 SO-DIMMs with CL42 timing and 1.1V operation before purchase.

Questions about this item

Does my laptop need a DDR5 262-pin SO-DIMM slot to use this 64GB kit?

Yes, the kit uses 262-pin DDR5 SO-DIMM modules that require a compatible DDR5 slot running at 1.1V.

Will these CL42 5200MHz modules downclock automatically if my system only supports a lower DDR5 speed?

Yes, DDR5 modules negotiate the highest common speed with the memory controller at startup.

How can I confirm both 32GB modules are running in dual-channel mode after installation?

Check the memory speed and channel configuration in your BIOS or a tool like CPU-Z to verify dual-channel operation at 5200MHz.
