32GB DDR4 SODIMM for Lenovo ThinkPad L14 L15 P1

This 32GB DDR4 3200MHz CL22 SODIMM is built for compatible Lenovo ThinkPad L14 G3, L15 G2, L15 G3, P1 G3 and P1 G4 laptops. It delivers a straightforward capacity increase for professionals who need more memory headroom in these specific mobile workstations.

260-pin unbuffered non-ECC module at 1.2V

The module uses the standard 260-pin SO-DIMM form factor with unbuffered non-ECC architecture and 1.2V operation. It fits directly into the laptop's memory slot without requiring additional cooling, voltage changes or registered memory support.

32GB single-stick upgrade with JEDEC compliance

A single 32GB stick raises total system memory to 32GB or higher depending on slot availability and maximum supported capacity. It handles larger datasets and heavier multitasking workloads, but systems limited to lower maximum memory per slot or total capacity will not recognise the full amount.

Questions about this item

Does the CL22 latency limit throughput during long rendering sessions?

The module runs at DDR4 3200 with CL22 timing; latency is fixed by the JEDEC specification and does not change under sustained load.

How much heat does the 1.2V unbuffered SODIMM produce when the laptop runs all day?

Operating at 1.2V without a heat spreader, the 2Rx8 module generates only typical DDR4 SODIMM heat, well within the ThinkPad cooling design.

Which Lenovo part numbers must already be in the ThinkPad for this 32GB upgrade to work?

It replaces Lenovo parts 5M30Z71652, 5M30Z71692, 5M30Z71711, 5M30Z71714, 5M30Z71755, 4X71A11993, 4X71D09536, 5M30V06797, 5M30V06804, 5M30V06807, 5M30V06973 and 5M30V06981.
