Can confirm. Happened to me with my old laptop. Tried to upgrade it with some rescued RAM and it refused to use all of it. It would only use up to the laptops advertised max.
(Not the brand in question, but motherboards can definitely limit the RAM utilisation)
I assume it is the racial slur originally directed at Pakistanis but is now used against all brown people because racists can’t tell the difference. Not that it would make a difference if they could. Racists gonna racist.
