hi all,
Just upgraded my 9800gt to the vapour-x radeon 5770 and wanting to dive into the overclocking world. I hear the ati control centre is simplest to do with this card but as i have no experience and don't want to kill anything any help is greatly appreciated.
 
Simple: Unlock the controls, set fan speed to 50%.

At first, try maxing out the sliders and hit apply. Then, run a game or furmark or something. the 5xxx cards use ECC memory so you won't see artifacts, but the screen may flash or be jittery. And you can still get artifacts from the core.

If it's unstable it might crash or restart whatever you're running. In that case, go back into CCC and drop the core clock by 20mhz and the memory by 50mhz and attempt to stress test again. :)

If you want to overclock further like i did, use MSI Afterburner and use the voltage control.
 
i'd use ati tool. really easy to use and see artifacts. using that i'l see artifacts well before i'll start to get the jitteryness that linkin mentioned. with the 5770, you should be able to get to about 930-960 on the core and about 1400 on the memory before having to up the voltage. if you do want to push it further then definitely get msi afterburner like linkin said and up that voltage a little. i got mine to 1000 and 1400 with a minimal voltage bump.
 
they are sort of "errors" in the display. they can look like little odd blocks on your display (i think the term itself extend to other visual issues as well).

but when you use atitool they look like this:

usually you won't start to seee anything on your screen in the desktop area but you will see it in the atitool window (you'll see it in atitool first). move the bar in ccc, click apply, then run "scan for artifacts" in atitool and look for the yellow stuff. if you see any, lower your oc until you get the max without artifacts. i would start doing only one thing at a time (core or memory) and find the max for it, then move on to the other one.
 
ok well on clock settings 960mhz and 1400mhz memory clock settings and 50% fan speed it gave no errors after 5 mins running. temps on 38c avg on idle and when scanning for artifacts temp 57c avg.
 
That's good. I had to raise voltage on mine because of XFX's cheap ass move... cut out some power phases and got rid of one of the Cf connectors :(

Try running 3dmark06 at stock and overclocked, see if there is any difference in score :) although 06 is more like a cpu benchmark.
 
that is a very nice overclock :good: those are good temps as well, right on par with what i would expect. if you want to go any further you'll need to up the voltage.

Click to expand...

Don't use atitool....use furmark, furmark is better representational of a load you will encounter while gaming.

ECC memory only prevents artifacts from memory linkin, not the gpu core, so you won't artifact from memory overclocking, but you can from core overclocking.

I know that :P thought i mentioned it somewhere.

Now that my core is at 1ghz with 1.25v i do get some small artifacts in CSS but that's all. everything else is fine.
 
is their a fur mark for windows 7. It said vista and xp on site but i tried it anyway and i got a black frozen computer after 1 minute and after restart it had recovered from blue crash.
edit - i ran it for 3 mins and after that with atitool it goes to a blackscreen and is frozen so i restart. I have taking back to defaults for now.
