CAMM2, the new standard replacing SO-DIMM?


Little by little, standards in the computer and PC world are evolving. We had the perfect example just recently with the arrival of NVIDIA’s power connector: the 12VHWR. Admittedly, this is a bad example for reasons we all know, but it also has its advantages. On the memory side, things are moving too, with JEDEC presenting a new format for RAM: CAMM2. This is intended to replace the SO-DIMM used mainly in notebook PCs!

CAMM2, the replacement for SO-DIMM ?

JEDEC CAMM2In order to promote its new format, you need advantages to get it adopted. Clearly, that’s not what’s lacking, since despite its considerable dimensions, it actually saves space. In fact, a module of this type is 57% thinner than a SO-DIMM. It also has the advantage of offering higher density, with modules up to 128 GB, while being faster at the same time.

While the current SO-DIMM limit seems to be 6400 MT/s, Samsung’s own LPCAMM format reaches 7500 MT/s in LPDDR5X. A good thing for notebook PCs in particular. Fast memory is particularly useful for iGPU-equipped laptops, which make up the majority of machines on the market. What’s more, the slimness of the modules also helps to reduce the footprint of the machines, as well as their weight.

A final advantage offered by this new standard: dual channel is available via a single module. In theory, this format should gradually replace SO-DIMM. Note that this standard is based on the format proposed by DELL.
