I recently had two 4830's in crossfire and I sold them to my friend and I had them overclocked to, now my friend wants me to OC them more for him.
Core: 575/685 on both and
Memory: 900/965 on both.
Temp: Sapphire video card is 42C powercolor is 38C
When I run furmark with 10 mhz higher on either ram or core I get slight blue lines (hardly knoticable, but they are there), what I want to know is is it safe to overclock them more? because furmark is such a crazy test? or should I stay with what I have now? is there another artifacts tool that will let me OC higher without artifacts but still keeping it safe?
