I recommend all ATI users do this fix regardless of their card model. New drivers may change your card's behaviour to cause you to be affected.

Mine definitely clocks properly now, since i'm getting the same "reboot after 40 minutes" that i got when forcing the clocks via Ati tray tools :-P

It's weird because i've never had problems in any other game. I'll try switching it to a different slot so that it gets better ventilation within the case. Failing that, it could be a power supply issue (the leads could be delivering low amperage). I use a 700w thermaltake PSU that i recently got after my previous one died, maybe i have to RMA this one too...it's a good thing the guy i buy from only carries brands with a 3 year warranty :grin:

So, just in order to gradually eliminate possible causes and find out what's to blame, if i set GPU-Z to log the parameters to a file does it only log what has been monitored up to the point that i enable the log function and specify the file name? Or does it keep appending to that file for as long as it's running (which would mean it would record up to the point the PC reboots)?

The reason i'm asking is that i need a logfile showing my temperatures at the moment the reboot occurs, this way i can decide if i just need to add an extra case fan or if i should look for other problems. Any ideas?

You could try to underclock your CPU and/or GPU just a bit to get its power usage down (5 or 10% should already make the difference). This way you could test if your system holds out longer. Of course I've assumed you don't have any heat issues with your case, GPU or CPU. You could also check if the fan of your power supply is working properly.

Simply rename or delete the Ubisoft logo video found in \Steam\steamapps\common\il-2 sturmovik cliffs of dover\parts\core\GUI.

It has fixed the issue for my HD4870 and alot of other AMD users! :)
