Laptop RAM formats compared: LPCAMM2, CAMM2, soldered, and SO-DIMM

Laptop memory formats are shifting, with new standards like LPCAMM2 offering a balance between performance, upgradability, and thin design, while soldered RAM remains common but non-repairable. The article compares four memory types: soldered RAM, CAMM2, LPCAMM2, and SO-DIMM. Soldered RAM is thin but cannot be upgraded. CAMM2 and LPCAMM2 are new, swappable standards supporting up to 128GB, with LPCAMM2 targeting thin laptops. SO-DIMM is older, limited to 64GB, and slower. For buyers, LPCAMM2 is recommended as it offers future upgradability. CAMM2 is not yet in laptops. Soldered RAM suits those prioritizing thinness, but buyers should choose capacity carefully. SO-DIMM remains a safe, widely available option.
