Does anyone have any idea how i can check if my cards are Samsung or Micron memory in ubuntu? i've looked but i cant find anything that will tell me this info.
this cmd will give you detailed information; but its not as helpful as some of the windows tools:
lspci -vnn | grep VGA -A 12
You should be able to use the memory info from this cmd to identify different manufacturers.
I don't have this info; but I am reasonably sure that is how the windows applications which provide this work; and it is available somewhere on the internet.
