Unlike SO-DIMMs, it is secured with three screws
Lenovo ThinkPad P1 Gen 7 became one of the world's first laptops with LPCAMM2 (Low Power Compressed Connection Memory Module) RAM, and now experts have disassembled the laptop and shown the corresponding module live.
LPCAMM2 is installed using three guides and fixed with three screws, the module itself is marked with tightening torque data. The installation principle of LPCAMM2 is completely different from SO-DIMM: no self-locking fasteners.
Compared with SO-DIMM, LPCAMM2 consumes 58% less power and takes up 64% less space in the case. Another important difference from SO-DIMM: each LPCAMM2 module is dual-channel by default, so one LPCAMM2 is sufficient for optimal system performance.
By and large, LPCAMM2 has only one minus so far — price. For example, the cost of one 64 GB LPDDR5X-7500 module from Micron is $330. However, other manufacturers are already involved in the production of LPCAMM2 — Yingruida, Samsung and ADATA, increased competition in the segment should bring prices down over time.
