Hi, I have a Probook 4540s and have recently upgraded it from 6 to 12 GB RAM. (the two RAM sticks have identical timing)
Because of the degrade of performance after installing more than 8GB of RAM
(as described in this topic http://h30434.www3.hp.com/t5/Desktop-Boot-and-Lockup/Performance-degrades-in-Probook-4540s-after-mem...),
I had to us msconfig to set the memory limit to 12032 MB.
However, windows now says that only 10.4 GB is usable. I really appreciate your help.
