Whats problem?
Standart examples all work on video card! I have Radeon HD 6770
Does OpenCL work with your card?

What OS, and what version of AMD drivers?

What is the output of hashcat -I?

Edit: it looks like that card has been "no more driver improvements" since 2015?
Windows 10x64 professional
Install old driver whql-win10-catalyst-15.7.1-oct30.exe

hashcat -I
