Core/Memory/Shaders - score

700/1000/1750 - 4400 (base settings)
800/1000/1750 - 4950
700/1000/1900 - 4900
700/1100/1750 - driver crash

Seems memory may be making problems, trying it now at 1050 and will see how it goes. But it’s already good, a 10% increase in score with only raising core by 100MHz.
