Overclock xfx 4890

[adamh9]

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?

Yes u can try increasing the fan speed manually...
U can try "Riva Tuner"...

 

[adamh9]

by increasing the fan speed this can help prevent lockups or artifacts?

 

[wa1]

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...

 

[adamh9]

yea my temps seem pretty average thats why i'm confused. you think a third party fan controller would help?

 

[wa1]

So, what are your temps exactly?
If that the case then i think an aftermarket cooler wouldn't help u...

 

[adamh9]

i idle around 41C and max at about 60+...maybe i just got a bad card?

 

[wa1]

your temps are good...
Why u want to OC? i think your 4890 is fast enough.
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?
