48 GB DDR5 SODIMM for laptop upgrade

This 48 GB module uses 262-pin DDR5 SO-DIMM form factor and runs at 5600 MHz with CAS latency 40. It is an unbuffered, non-ECC stick built as a direct replacement for the Samsung M425R6GA3PB0-CWM part. The single-module design suits notebooks and all-in-one systems that have one slot available.

Low-voltage DDR5 runs cool and quiet

Operating at 1.10 V, the module draws minimal power and produces negligible heat without a spreader. Passive cooling in a typical laptop chassis is sufficient, so fan noise does not increase under normal workloads. The standard DDR5 voltage also helps preserve battery life during mobile use.

2Rx8 layout fits tight SODIMM sockets

Major-brand DRAM ICs are assembled on a bare green PCB that matches the 262-pin keying of DDR5 SO-DIMM slots. The 2Rx8 organisation works with laptop memory controllers that support this density. Buyers who need ECC error correction or registered buffering should choose a different module.

Questions about this item

How do I install the 262-Pin DDR5 SODIMM, and which step do people often miss?

Align the notch on the module with the slot key, press firmly until the side clips click, then verify the BIOS shows 48GB at 5600 MHz.

What maintenance or replacement will this 48GB DDR5 module need later?

No scheduled maintenance; if errors appear, reseat the module or run a memory diagnostic to confirm the 2Rx8 chips are healthy.

What limit appears first during sustained workloads on this 1.1V DDR5 5600 SODIMM?

Thermal throttling from the laptop chassis can reduce throughput before the 40 CAS latency or 1.10 V rating becomes a factor.
