CAMM2 (Compression Attached Memory Module) RAM is still very new and has been found in a very limited number of systems at this time, but we may soon see wider adoption as GIGABYTE’s product manual suggests that CAMM2 is coming to desktop motherboards.

YouTube channel Gear Seekers posted a video focusing on the company’s new Z890I AORUS ULTRA motherboard – surprisingly, the product manual included in the packaging has listed several Z890 models, including a special variant of the AORUS TACHYON ICE that uses CAMM2 modules instead of the traditional DIMM designs. It’s worth noting that GIGABYTE’s TACHYON series mainly focuses on extreme overclocking features.
In case you didn’t know, CAMM2 feature a completely different installation mechanism – DIMMs are secured using slots, while CAMM2 requires screws to secure into a ‘socket’ similar to that of CPUs. This standard was first developed by Dell, which was later adopted by JEDEC (the body overseeing the memory standards) as the new standard to supersede DIMM/SO-DIMMs, and has now feature two versions, CAMM2 and LPCAMM2, the latter is designed for laptops.

That being said, while one of the advantage of CAMM2 is the potential to enable higher clock speeds, the debut of CUDIMM modules has largely negated that thanks to the inclusion of clock driver. Still, being standardized means OEMs will eventually adopt the new standard, though it might not happen in the immediate future, at least.

Pokdepinion: Thanks to CUDIMMs, I do think CAMM2 has less advantage on a desktop platforms – but the advantage on a laptop is certainly still there thanks to smaller footprint.
