A-Tech 32GB DDR5 4800MHz CL40 262-Pin SODIMM Laptop RAM

SKU CH-HGS0-JPQ2Y

A 32 GB DDR5 laptop module running at 4800 MHz with CL40 latency and 1.1 V operation

  • Capacity32GB
  • Type262-Pin DDR5 SO-DIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCNo
  • 32 GB capacity lets you run heavier workloads and multitask smoothly
  • DDR5 4800 MHz speed delivers high data-transfer rates for responsive performance
  • CL40 latency at 1.10 V balances quick access with standard DDR5 power efficiency
  • 262-pin SO-DIMM form factor fits laptop, notebook and all-in-one memory slots
  • Non-ECC unbuffered design suits mainstream consumer systems without error-correction overhead

32GB DDR5 4800MHz SODIMM upgrade

This 32GB module uses DDR5 technology at 4800MHz with CL40 latency and runs at the standard 1.10V. It fits laptop, notebook, and all-in-one systems that accept 262-pin SO-DIMM memory. The unbuffered, non-ECC design matches mainstream mobile platforms.

Replaces Corsair CMSX series modules

The module is a compatible replacement for Corsair CMSX64GX5M2A4800C40 and CMSX32GX5M1A4800C40 kits. Builders moving from lower-capacity or slower DDR5 SODIMMs gain a direct drop-in upgrade. The jump is worth it when the system supports 4800MHz operation and the single 32GB stick meets the desired total capacity.

Fits 262-pin DDR5 slots without a heat spreader

The bare circuit board slides into tight laptop chassis where taller modules cannot fit. Running at 1.10V keeps power draw low for mobile thermal envelopes. Buyers who need ECC error correction, registered buffering, or a second module to reach 64GB should look elsewhere.

Questions about this item

Will this 262-pin DDR5 SODIMM fit my laptop's memory slot?

The module uses the standard 262-pin DDR5 SO-DIMM form factor, which matches any laptop slot built for DDR5 SO-DIMMs.

What is the correct way to seat the module so the side clips engage?

Align the notch on the gold edge with the key in the slot, press the stick straight in until the gold fingers are fully hidden, then push down until both side clips snap into the module notches.

Does this 1.10V CL40 stick need any firmware updates or thermal-pad replacement over time?

No firmware or thermal-pad maintenance is required; the unbuffered non-ECC module runs at standard 1.10V DDR5 voltage for its service life.
