  • 2 V operation reduces power draw
  • 260-pin SO-DIMM fits compatible laptops

What this module does and who it fits

This 8 GB DDR4 SO-DIMM runs at 3200 MHz with CL22 latency and 1.2 V operation. It is built for laptops that accept 260-pin unbuffered non-ECC memory. The single-rank 1Rx8 organisation suits mainstream notebook upgrades where a single slot is available.

Check your laptop before ordering

Verify that the original part number matches L46598-001 or 937236-855 and that the system supports PC4-25600 speed. Confirm the motherboard uses 260-pin SO-DIMM sockets and does not require ECC or registered modules. Most parts are not interchangeable, so cross-reference the exact MPN before purchase.

Thermals noise and power in daily use

Operating at the standard 1.2 V keeps power draw low and heat output minimal inside a closed chassis. The module has no moving parts, so it adds no audible noise during normal workloads. Typical laptop cooling is sufficient for this memory under everyday multitasking.
