XFX HD4890 Overclocking Help ?

[kevy1986]

Hey Guys,

I've got a HD4890 that I run at 2048 x 1152 ( Dell SP2309W )

I have an XFX ATI Radeon HD 4890 1GB GDDR5, which btw cost me £230 at when it first came out, how gutted am I now £164.99 !!!! I would like to know if anyone else has this card and how they've gotten on overclocking it ? I have used Furmark and CCC to overclock it but started to notice atrifacts when I pushed it hard ( can't remeber exact settings, think it went up a fair bit tho ) I have read about the asus card having a voltage tweek that apparently lets you run them pretty high. As the price has dropped quite a bit I don't feel so bad about overclocking it again.

So firstly does this voltage tweek only work for the Asus card ?

Has anyone found a way or another App to change the voltage ?

What are your temps and settings on your HD4890 ?

I've pretty new to overclocking GFX cards i've only ever done my CPU / Ram ect so any help would be appreciated.

Thanks,

Kev
