Hello there,
I’m very sorry that we don’t have information about launching the 64G RAM version of SER9 225 for the time being.
It is suggested that you pay attention to the information on our official website.
Regarding the USB-C interface of the machine you inquired about, if the PD power supply you are using exceeds 100W and your monitor is powered separately, then the USB4.0 interface of the SER9 can meet the requirements you inquired about.
Have a nice day~
