Morning folks, I'd like to overclock my Palit 560Ti 2Gb card but have never overclocked a GPU before. I've installed MSI afterburner, and under stock settings my GPU temp maxes at 61 with the fans on auto. Driving the fans manually at 40% my max temps are 56. So, I reckon I've some headroom. How do I go about overclocking on the stock voltages, which I'd rather not change? Many thanks, Cleggy.
if you move the core clock slider up in say 25mhz increments, then stress test. keep doing this until you have a crash or start to see artifacts in the stress test. then do the same with the memory slider, although memory doesn't tend to clock as high. keep an eye on your temps, and just leave the voltage setting alone if you don't want to go above stock good luck
As an addendum. When your computer crashes - adjust the slider backwards in 5 mhz increments. This way you can eventually find the maximum stable overclock.
What I did with my 580 with Afterburner is I cranked up the voltage to max, went for a middle of the road OC like 900MHz then tested stability.
Just have a play about with it, there is no right or wrong way to do it, your gpu isn't going to suddenly die from you trying to push it a little too hard on stock voltages/air
You'll only kill something if you run it at far to high a voltage for far too long. Reccomended way, if you're going to Overvolt, is find the maximum stable frequency, then slowly back off the voltage till it fails, step it back up to the last stable, and you've found the sweet spot. Just make sure the card doesn't roast under it's own heat. Incidentally: This is easier under W7, as the Driver just crashes and restarts without any problems, so you shouldn't get a Blue-screen simply from overclocking the GPU.
Kinda jumping into your thread here Cleggmeister as im about to overclock my 560 too hope you don't mind! Using afterburner the Core clock and the Shader Clock are both linked, should I leave them linked? or would I get a better overclock adjusting them separatly?
I don't mind at all mate! Just watching the football (come on West Ham!) and I'll go and have a play around. To be honest I've not found a need to over clock as yet since everything I play, maxed out, runs fine, but I'd like to have a muck around anyway.
Still currently messing with my card, every time I push up the core clock and shader clock should I run a benchmark? or should I keep pushing it until I see artefacts on the desktop and then back off and test? If it even makes a difference lol. Also the heat from the card wont increase unless I alter voltages right?
I run a couple of windows of rthdribl while testing. It means you can up the frequencies on the fly and make a note of the last stable settings.
Hmm, So I went up to 980 core clock, been backing it down and im now at 960 core and 1920 shader clock. Ran Unigine heaven benchmark for around an hour, all seemed good. Then I played some Mafia II for 45 mins and it was fine.. So I assumed that so far it was stable, then while editing some videos the theme in windows 7 switched from Aero to some basic view and everything ran really slowly.. had to log off and on again to get things back to normal This overclocking business is rather fun ! Kenco, how many windows of rthdribl do you have open at once when testing?
I just run Furmark, the hideously overpowered beast, while I tweak the clocks. Sadly this little 250 won't go higher than about 100 mhz on the Memory, 40 on the core and 60 on the shaders, but every little helps! Irregardless: Running something 3D, a Benchmark especially, while you Overclock, is a great, albeit unstable, way of overclocking GPU's on the fly.
I usually run two windows of rthdrbl. Once you're okay with the core speed, try upping the gfx ram speed
So, I've clocked mine to 880/1760 (core clock/shader clock) and 2050 on the memory, no other changes and all is well. Added 3 fps to most games, no extra temperature.
