560 Ti Hawk downclocks itself - Page 3

post #21 of 23
Well if it happens after all of that then I would google it and see if anyone has had similar issues with your card ? Perhaps even a BIOS update for the card.

Contrary to what my good man Enterprise suggested above, it IS possible for Fermi cards to downclock due to an unstable overclock, even w/o heat being involved. So you should def. try the reference clocks just to see if that solves it. Turning off adaptive power mgmt. as suggested above may fix it as well, but I wouldn't get your hopes up on that one ... I've seen this suggestion a 1000 times on these boards, and it rarely solves this issue unfortunately ... although it certain seems like it should ...

One thing I've never heard of is a card downclocking because of 'dirty' power from the PSU ... that's a new one on me EP

Very odd as my Fermi card ( 470 ) never did that to me and I knew full well my OC was unstable. Must be new, that or I had a special Fermi card.

Yeah GPU's will downclock where possible ( Via automatic driver protocol ) if the card is not getting sufficient power. Thats a fairly well known thing. On many systems I have dealt with, this has been the case, even one of mine very recently with an OLD agp card. The nvidia sentinal detected not enough power was received and downclocked the card. This is unlikely to be the case with him, plus he would have been notified.
