I have a HP Pavilion 14-v052tx that comes with Nvidia GeForce 830M GPU. Speccy shows it's revision number as 'A3' while GPU-Z and CPU-Z show the revision number as 'A2' (see screenshots below), I hope it gets fixed soon.
Under the 10041 build of WIN 10 Speccy crashes the computer and forces a restart no even when I try it in Win 8 compatibility mode. Does not work in Win 10 no matter what, crashes the computer and forces a restart.
and as the thread title says, do you also get the wrong revision of your graphics card shown.....
but as you will be aware, Win10 is still in beta, plus v10041 has only just come out, so until Speccy catches up (and if Piriform even deem it necessary) there may always be some software that won't work, as stated by Microsoft when you joined the program for Windows 10.
