Currently I am trying to install a 8GB RAM in my HP ab029tx(preinstalled 4GB).
I inserted it one the 2nd SODIMM slot available and it got clipped as normal.
But returning to windows , it is showing only 4GB(preinstalled).
RAMMON from passmark is detecting the RAM in 2nd slot as shown in below image.
But according to my windows10, there is no existence of the 2nd RAM.
I uploaded detailed result of RAMMON in html format in google drive.
I have checked msconfig and max RAM is unticked there.
And according to spec, it supports upto 16GB. hp link
Please help !!
