48 GB DDR5-4800 SO-DIMM for laptop upgrade

This 48 GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10 V operation. It uses a 262-pin SO-DIMM form factor and 2Rx8 organisation with major-brand DRAM ICs. The unbuffered, non-ECC design targets standard laptop memory slots.

Suits owners replacing a Corsair

Builders who need ECC or registered memory cannot use this module. Systems requiring a heat spreader will not find one here. Buyers wanting a matched multi-module kit should look at something else.

48 GB single-module capacity decides fit

A single 48 GB stick fills one slot and doubles typical maximum densities. The 2Rx8 rank structure may require specific slot population rules in some laptops. Verify the system manual before purchase.
