Step one before we help you further: download the latest version of MSI Afterburner.

Sorry, went to sleep a little early last night. What you want to do on Afterburner is look at the main dials on the program.



All that we are going to focus on here is the Core Clock dial. What you want to do is gradually increase the core clock (I use increments of +50). After you bump it up 50 MHz, I like to run EVGA OC Scanner X: http://www.evga.com/ocscanner/ for 2 minutes on the Furry E Core Burner Benchmark, to test for stability. I usually leave artifact counter on and make sure it says 0 at the end of the 2 minutes. If nothing crashes and there are no artifacts, keep bumping the core clock (be sure to click "Apply" in AfterBurner). Eventually, your computer WILL crash, but don't freak out, it is part of the process. All we're doing right now is testing to see how high you can go on stock voltage. Also: Use Afterburner to keep an eye on those temps.

I would leave my fan on the highest it can spin without annoying you, as you are going to mainly run this thing 24/7, or at least in games.

EVGA software said it work only on 64 bit system.
My fan speed is currently on auto(40) and my GPU works at 27 temperature idling and increses to 36-39 while playing a demanding game.

So i should increse vent speed from auto to max? Do i need to increse the voltage? Is it safe?
And other options i just increse core clock only? Don`t i need higher voltage? (i read this somewhere)
Are you sure there is no risk pushing up core clock?

Note that i don`t need too much overclock, i want only to play witcher2 a bit smoother smile.gif



Edit: i just incresed Core clock from 810 to 909 and vent speed from 40 to 80.
Edit2: afterburner showed 56 temp so i incresed vent to 100%

909! That is already a great overclock for your card! If you are happy, keep it. Also, don't be afraid of that 56 degrees, it is actually quite cool and doesn't require that full fan speed.

If you ever want to go higher, we can get into voltages. wink.gif

Edit: Since OC scanner X won't work, why don't you stress test and play witcher for 20 minutes or so. If there is no crashing, then you are good. I'm not sure how much farther that card will go past 909 on stock voltage though.

Well thats exacly what i did accually tongue.gif i played witcher 2 (in huge melee fight with lots of effects)

I was on 933 core clock and i reached 58 temperature and it didnt crash

What exacly is the diffrence between memory clock and core clock and should i increse memory clock too?


Edit: Ok it just crashed, i got blue screen at 933 (but i wasn`t playing) i was browsing the web with no stress to the video, reduced it to 899 now

Well, again blue screen but im not sure if because of overlock, before i did it i also got a blue screen.
