well i'm not sure if i did this right but stock settings where GPU clock-975MHz and i overclocked it by 10MHz incrementals up to 1050MHz, stressed tested it for a good 2 hours with no crashes and idle temp is 36C and max 58C. Do i do the same process for memory clock or is oc mem not necessary? i increased power limits to 20%
My next step it so overclock my cpu but thats a bit harder imo starting with my GPU for now
You could add a little on the memory, but for most cards its not worth the extra time, heat, and possible instability. The performance increase is USUALLY almost non existent. Spend the time on the core clock. If you are looking for more you could add some voltage and go for 1100+.
well i have overclocked it to 1100 stock voltage and idle temps are 37C and max is 51C how far should i go? what would be a safe temperature? i used MSI afterburner thanks for the suggestion
Try loading a demanding game and cranking the settings, making sure your GPU load is at 100%, turn vsync off etc and just let it sit for a little while to see the max temp. 51C is very safe.
well i used chivalry at ultra everything maxed out on a 64 player server played for about 1 or 2 hours. I know there are programs designed to test stability, should i download one or just play maxed out games lol?
its a gigabyte HD 7850. i tried out MSI Kombustor and that kept my gpu load 100%. temps got higher to 59C max at 1150MHz lol i left it running for about 20 mins i think
That thing OCs pretty well. Try downloading Unengine heaven and benchmark it, there is a thread with a lot of activity that you can compare results with. Benchmarking before OC and after OC and so on, 59c is great with that overclock.
Ok so I just played kf2 for a while And tried to play chivalry but as soon as a game starts my cpu usage goes really high 97% and freezes then crashes my computer tried kf2 and it works good. I brought down the card down to the stock OC limit 1050 and it runs without crashing I was playing chivalry fine at 1100 before and now it crashes? Just chivalry
Ok so I figured out the crashing problem my OC wasn't so stable. I downloaded heaven and my sweetspot is 1090 I don't think it's that bad 975 to 1090. I have room for more though since i made sure to make sure it was stable this time. ran several tests over 2 hours and Temps never rose beyond 56 max settings on heaven. From what I understand if I want to over clock it more I have to increase my voltage correct? I tried increasing power limit but it won't go beyond 20% so I guess that's at max. I tried looking what's my max operating temp but didn't get solid info Fan speed I set to manual to 70 from the stock 40
You can indeed increase the voltage for a higher OC, but doing so also makes it run hotter. I'm pretty sure you can push a mid range card like that rather high.
