For instance, the Lenovo X1 Carbon Gen9 features "16 GB LPDDR4X 4266MHz (Soldered)" – does this setup support dual channels? I don’t remember any reviewers mentioning this specific soldered RAM configuration. It seems some laptops with similar specs include an extra DIMM slot for upgrades, but these ultrabooks lack such options. I’m curious because I noticed performance improvements in the apps after swapping two identical RAM sticks versus one.

It seems unclear why dual-channel soldering isn't supported. Including modules in the motherboard helps achieve a more compact design. You might want to look at user reviews to verify the specifications, since Lenovo doesn’t share this information.

I just checked it on my favorite site and saw it’s actually supporting quad channel. LMAO! https://www.notebookcheck.net/Lenovo-Thi...905.0.html

It doesn't work in the QCD channel. The CPU only supports two channels. It seems to be similar to a 4-stick setup with dual channels and dual ranks.

Must be a bug, the cpu only accept 2 channel max. https://ark.intel.com/content/www/us/en/...h-ipu.html

They were right about the limit being two channels. It might have been a misstatement from the software or a simple error.
