Dell has released a new Precision 2022 mobile workstation product line, which not only debuts the Intel Alder Lake-HX series 12th generation Core Top Mobile Edition, the highest optional RTX 3080 Ti graphics card (and intel Arc professional graphics in the future), but also brings a new CAMM DDR5 memory form.
CAMM, known as "Compression Attached Memory Module", is a new form of memory that is different from traditional SO-DIMM notebook memory, not only thinned by 57%, but also has a single capacity of up to 128GB (also optional 64/32/16GB), which is equivalent to four standard 32GB DDR5 SO-DIMMs, which is very suitable for workstations that require large amounts of memory.
Of course, it is much larger, a small PCB board, both sides of which can be mounted with memory chips, using two upper and lower pressure plates (bolster plates) fixed to a special CAMM Compress interface.
Interestingly, according to media reports, CAMM is not unique to Dell, but jointly built with memory manufacturers and Intel, but Dell did contribute most of the design and applied for patents.
In terms of specifications, the frequency of CAMM DDR5 128GB is only 3600MHz, and 64GB, 32GB, and 16GB are standard 4800MHz.
128GB and 64GB are double-sided, and 32GB and 16GB are single-sided.
The capacity of a single particle is 2GB, so 64, 32, 16 and 8 chips are used respectively.
It seems that CAMM DDR5 does not support ECC, which is a loss for workstation applications.

Of course, if you don't need this special memory, the Dell Precision 2022 series still offers standard DDR5 SO-DIMMs, including a single 8GB, 16GB, dual 8GB, 16GB, 32GB, all at 4800MHz, and optionally support ECC.
Curiously, Dell even offers a conversion bracket that can be installed with SO-DIMM memory at the same time, but it is not clear what the significance is, is it allowed to be mixed?
