Hey all, I think I need a little help.
I have an EVGA GTX 470 and I tried overclocking it before. Made a few mistakes and learned from them. My overclock (pretty conservative 705/1410/1720 @0.987V) passed EVGA OC Scanner and the custom fan profile definitely helped keep temps under control. I was thinkin of going higher but ran into a problem with Furmark and Crysis
Furmark and Crysis kinda killed my oc . They both reset the core clock back to lowest speed (450mhz) after err....yeah I don't know what (though some ppl have said to not use Furmark for oc testing). I played Crysis and kept a sharp eye on the temps. Temps never went above 95c for either I believe. During gameplay or Furmark testing, the fans would just suddenly.....die. The clock rate dropped and fan speed pulled back and fps went into the single digits. I tried controlling heat and changing voltages but nothing seems to keep it stable in crysis.
So a basic question about overclocking. Why do overclocks fail?
I was under the impression that they fail either because of
A) Not enough power supplied to the card, so more voltage is needed
B) Too much heat, sometimes because of increased voltages
Any ideas? Stock runs fine but.....you know how it is when you start overclocking >_>
