Armory crate not showing CPU stats means there is a problem with the XTU service its relying on to read these stats. Download this troubleshooter and run it:*https://dlcdnets.asus.com/pub/ASUS/GamingNB/GU502DU/ArmouryCrate.XtuTroubleshooting_v6.51.371.0.zip?...
I had the same problem too and the troubleshooter fixed it.
For the 3ms response time switch, it seems like there is a problem with the monitor refresh rate service. Here is the latest version of it for this laptop*https://dlcdnets.asus.com/pub/ASUS/GamingNB/FX505GD/RefreshRateService_V2.0.3.zip?_ga=2.35422625.144...
For overclocking GPU and CPU through armory crate, i donâ€™t really know, the same thing happened to me but i couldnâ€™t find anything anywhere. Just use MSI afterburner:*http://download.msi.com/uti_exe/vga/MSIAfterburnerSetup.zip
Itâ€™s much better than armory crateâ€™s overclocking anyway, my OC is +160Mhz for the GPU and 500Mhz for the memory.
You canâ€™t do much with CPU and i recommend you actually undervolt it because it gets really hot.*
