Apparently I can choose 192GB RAM non-ECC (4 x 48GB) from Lenovo website, it just that when I try to configure with ECC the maximum 128 GB RAM ECC (4 x 32GB) is only allowable with i7 not i9. Perhaps you can check other Intel CPU core and select the one that is fine with the RAM configuration.
Looks nice other than the low resolution screen given it's a 16"
The maximum resolution option on the Lenovo page is 3840x2400. I think the starting option at 1200p is... ok.
I'm sure that as usual the higher res options will be available in the US only
Huh? Last time I checked any option on any thinkpad was available for special order and delivery to pretty much anywhere in the world outside a few countries, and that even includes full warranties, at a markup of course.
