In high-end ultrabooks, does soldered & un-upgradable memory run in dual channel?

For example, the Lenovo X1 Carbon Gen9 offers "16 GB LPDDR4X 4266MHz (Soldered)"

Does this config run in dual channel? I cant recall any reviewers talking about this aspect of soldered ram

I understand some other models of laptop offer 8gb soldered + an extra dimm slot for user upgrades.

But for these ultrabooks that dont have any extra Dimm Slots , what do i make of it?

 

I only ask because in the past i have personally seen gains in the apps i use - when i upgraded to two identical sticks of ram vs single stick

I don't see why they can't solder 2 modules in dual channel mode.

The point of incorporating the modules in the mobo is they can reach a slimmer body.

Best to check some reviews to confirm the specs as lenovo doesn't provide it.

you're correct, max channels is 2 on this CPU
im guessing they stated quad channel because of how the software reports it in windows
and/or they just made a mistake.
