Tried gpu-z but it didnt help
GPU-Z gives you quick access to PCI device ID and techpowerup database. The device ID can be found in the device manager too... This contains vendor/device/subvendor/subdevice ID, which is well enough to find out more on the web...
For example:
Gygabyte GTX 1060 3GB with PCI\VEN_10DE&DEV_1C02&SUBSYS_37221458&REV_A1
(Vendor) 10de=Nvidia
(Device) 1c02= gp106 card (1060 3gb)
(Subvendor) 1458= Gygabyte
(Submodel) 3722= Specific 1060 3gb model by Gygabyte (GIGABYTE GTX 1060 MINI ITX OC)
A1= Board/hardware revision
You could use
devicekb or simply google yours to find out more.
