Using ATITool, I adjusted mine core to 625MHz and mem to 725MHz, which is the listed specs. Does that mean it is the stock specs for the card?<br />
<br />
When I use these specs..I try to play a video, the whole system just freezes.<img src="/images/smilies/confused.gif" border="0" alt="" title="Confused" class="inlineimg" /> When I lower it to the default 500core 600mem, it works fine. Isn't it suppose to run normally with the listed specs?

To save power and heat the card clocks back to 500 & 600 when there's no 3d applications running, when you play a game it pops back up to the real speak you can use rivatuner (google it) to monitor the clock speeds to see what i mean. For more info search this forum, there's been a million topics about it

</div>I based my overclock attempt on Chozart's FAQ. But he didn't specify some stuff. Is the overclocking only supposed to be on if 3D-Apps were on? And all other times at the 500/600?

Make a Stock 3D profile, REMEMBER TO RAISE THE VOLTAGE, set clocks to 625/725. Then use that to make your own overclock profile. I've run the core voltage up to 1.575 volts, 2.3 for the memory and 1.5 for the extra voltage setting. I never run an overclock when playing games, because my CPU is bottlenecking the card anyways, I overclock to see how far the card will go. <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

I did that. I can't even play a video with it at 625/725. it would pause and freeze. Then I have to reboot.

You are sure the voltage is raised? Also switch to 625/725 and hit the "scan for artifacts" button.

RivaTuner. It worked for me when ATItool just crapped out on me.

</div>You can give it up to 1.575 volts, which I have done before without any issues besides heat.

Yes, I am supplying the card with direct power from the PSU. You sure 1.575 is fine? May I ask how can I fine the max voltage it can go?

Umm, 1.575 volts is the max. Your core will start smoking unless you have good cooling. I highly recommend not to run voltages that high for more than 15-30 minutes to find a max oc.

What voltage you recommend I leave it on? So I won't have to change it everytime..

1.425 volts. Maybe up to 1.475 volts for 3D mode.

I have the same card and had some trubles with it at the start, If you have a 3D profile made the only time you need to run that profile is when you need the power, 2D profile should be the stock settings to run movies. remember to have your fan speed adjust when temps spike. make sure your temp threshold isn't set too low and rais the speeds for higher temps and stock for 50-75. and run your 3d profile for gaming or CADwork or whatever you using the power for. you don't need to oc the volt higher than 1.45. When i run atitraytools i only use it when i start up games and have the 3d profile active, that seems to help.
