A-Tech 16GB DDR5 5600MHz laptop module

This A-Tech module provides 16GB of DDR5 memory at 5600MHz for compatible Dell laptops. It uses a 262-pin SO-DIMM form factor and operates at the standard 1.1V voltage. The unbuffered, non-ECC design features major brand DRAM ICs and a CAS latency of 40.

Suits owners of listed Dell part numbers needing

Buyers with a Dell system matching SNPXP90RC/16G, AC774048 or SNPW1KKYC/16G can use this as a direct replacement. Builders requiring ECC error correction or registered buffering should look elsewhere. Systems limited to lower memory speeds or different pin counts cannot use this module.

The 262-pin DDR5 SO-DIMM interface decides fit

Only laptops equipped with a DDR5 SO-DIMM slot can accept this 262-pin module. The 5600MHz speed rating (PC5-44800) must be supported by the platform for correct operation. Verify your system manual for memory seating and channel guidelines before installation.

Questions about this item

Should I choose a single 16GB module or a different capacity for my Dell laptop?

This module is a single 16GB stick. If your laptop has one free SODIMM slot, adding this 16GB module increases total memory by that amount. Check your system manual for the maximum supported capacity and whether a second identical module is recommended for dual-channel performance.

What does the 5600MHz speed mean for actual laptop performance?

The DDR5 5600 rating (PC5-44800) sets the maximum data transfer rate. In a compatible Dell laptop, the memory controller will run the module at up to 5600MHz, improving bandwidth for multitasking and data-heavy applications compared to slower DDR5 speeds, provided the CPU and chipset support that frequency.

Is the 262-pin DDR5 SODIMM interface compatible with my Dell and does it limit speed?

Yes, the 262-pin DDR5 SO-DIMM form factor fits the DDR5 memory slots in compatible Dell laptops listed in the compatibility data. The interface itself supports the module's rated 5600MHz speed; the actual operating speed is determined by the laptop's processor and chipset capabilities.
