at stock its 850/975, i can't get passed 875/975 without hangups or artifacts!! bad card? would higher fan speed help this? there are no voltage adjustments available for these cards as they are non-reference, specifically the ZSFC model. maybe another program besides CCC?

U can try "Riva Tuner"...

It depend...
the artifacts can be cause by an overheating or the card itself at it's limit...
Check your card temps first before OC... :)

your temps are good...
Why u want to OC? i think your 4890 is fast enough. :D 
If u can't get passed 875/975, then i think that's a limit point of your card.
DId u install the latest version of driver?
