I tried these two modules and and both worked without issue:
- Kingston FURY Impact PnP 32GB (KF556S40IB-32)
- Latency at 5600MT/s: 40-40-40-80
- Actual latency in the Laptop 12 at 5186 MT/s: 38-37-37-73
- Crucial 64GB (CT64G56C46S5).
- Latency at 5600MT/s: 46-45-45-90
- Actual latency in the Laptop 12 at 5186MT/s: 42-42-42-82
The Kingston has lower latency, but in the various tests I did (memtestx86, running games and looking at FPS, running a built-in benchmark in a game, building a fairly big C++/QT6 project (QGIS), processing a fairly big photogrammetry project with webodm) the performance gain (FPS or time to complete task) was only about 1%.
Since some of the things I’ll be doing on this laptop (photogrammetry, 3D modeling) benefit from more memory, I went with the Crucial 64GB CT64G56C46S5 in the end. But if 32GB are enough, you won’t be disappointed with the KF556S40IB-32.
