We probably need to have one of these. Recently, memory makers started to take a technology that we have seen for years on the server side, and bring it to the desktop and mobile platforms. The CUDIMM or CSODIMM adds a “C” for clocked, and with it comes some new hardware.

The big difference between the CUDIMM and COSODIMM and their UDIMM/ SODIMM counterparts is the addition of a clock driver. Just to see the difference, here is the front and back of Our Top 96GB DDR5-5600 SODIMM Kit Crucial 2x 48GB Kit.

Here is the Crucial DDR5-6400 CSODIMM kit that is 2x 16GB. Of course, there is a big difference on the right hand side since the 48GB modules have DRAM chips on the back, but if you look at the front, you will spot the difference.

Here is a close-up of the front of the CSODIMM. You can see in the middle under the label that there is a Montage clock driver chip.

On the CUDIMM side, we do not have a normal DDR5 DIMM in the CMS stright-on, but here is the label side of a Micron ECC UDIMM.
