R9 290x benchmark crashing at scrypt

hi!

I have my usual R9 290x (watercooled) and I was running benchmarks with version 3.30 and 3.40 

Using latest AMD drivers: 17.2.1, Windows 10 

The benchmarks on both the 3.30 and 3.40 crash exactly when scrypt is being benchmarked. The error is "Hash64.exe has stopped working". 

Any ideas what could it be?
