Problem finding max core of 4850

post #1 of 27
Thread Starter 
i installed ATItool yesterday, as i wanted to find the max core and max memory,
i clicked on find max core, left it running for straight 6 hours, all in vain
it was still running....then the power went out ( i am in india) so all my effort was rendered useless.....so i decided not to use it again....
Is this usual for this software to take this much of time, or it just happened with me?
cos maximum i've heard is 4 hours

and wat other software u recommend me for overclicking my card'?

use the catalyst control centre that installed with the drivers, go to the overdrive tab and unlock it then you can oc, up by 10 MHz at a time and use ATItool to check stablility

Just use Overdrive/ random OC tool and a benchmarking tool like Furmark. Keep upping the cores and memory. Check your temperatures and fan speed. When you get artifacts, you either are cooking your card, or just reached the max. Memory makes little dots/distortion. Core should make big triangles appear.

ok....and as for checking artifatcs, for how much time i shud leave the window running?

Most of the time after 10 seconds or less, just let it run. If it happens, lower and wait to see if it returns.

Also, try some games that stress your GPU. That way you're sure that your OC is stable. (No real need for 24 hour stress testing BS, just gaming for half an hour and Furmark will do)

Keep OCing, but watch the temps. Also, make sure that you're putting enough pressure on it, 800*600 no AA isn't good enough. 1024*768 and full AF/AA is the thing you want.

The overdrive was busted in the latest drivers.

690/1090 is a great overclock. good job.
