560 TI Overclocking question, voltages!

post #1 of 5
Thread Starter 
Alright i got 560 TI Frozer 2 OC last week and since day 1 i started overclocking it. I was using 950 core at 1.050 v core in that whole time ive had 2 errors at that setting one was last night on witcher the screen went black just before cutscene i thought this might be a game bug probably just failed OC though. i ran the game with Uber sampling for about 2 hours to see if i could get it to crash again but i couldnt get it to crash.

Then 5 mins ago on crysis, game froze and screen went black damn it frown.gif, was kind of random because i was playing it for a good hour and half earlier, this is with extreme settings and 2x AA.

Question is should i increase vcore to say 1.060, Overclocking GPU's is pretty new to me i only ever have done CPU's in the past, its hard to find solid info on what volts are within some sort of safety range.

1050 is stock. So if ur have the 880 core clock card than u should up the volts. I have the 900 and with 1050 volts I can get the core clock to 975. Not all cards are equal. What card do u have.

1012 is my stock volts for 880 mhz, i got MSI twin frozer2 OC card.

Ok so 1012 at 880 mhz. Keep at that 1012 and OC to 930mhz. Make sure that runs straige. Thats a fair amount of volts to clock ratio. If its good than pump the core by about 10. If u have issues, up the volts from 1012 to 1022(or 1025) something like that. 1060 for your 1012 stock might be too much. But will help u OC as best we can

I didnt get much chance to test it last night but i played some Dirt3 at 1012 volts and 930 core and it didnt crash, , i might just shove the voltage to 1025 to be on the safe side at 930 and then play some crysis, cant do this till later as i have work soon.

Crysis 2 seems to the best way to check for OC fails imo, becauase that was the game that made me bump voltage to 1050 at 950 because it seemed anythign less i would get black screen for a few seconds after a a matter of minutes.

I did actually Try 975 core at 1050 vcore and ran Unigine and it crashed in no time biggrin.gif so yeh my card is just a ****ty overclocker, like all my other GPU's frown.gif i would be happy with 930 mhz stable though so im going to aim for that.
