So a year or so back I setup an R9 380 to run on CRT-emudriver. For space reasons I had to dismantle that setup and used the PC with another graphics card for another purpose.
Can the R9 380 I pulled from the setup be sold or will it be in a 15kHz mode for the buyer

As far as I remember I only installed the custom drivers on the system level and didnt flash any custom firmware or anything... correct?
Just want to make sure its safe to sell.
Thanks
