wanna ask how do you guys judge whether your card stable or not, by running what software and usually how long to judge it?

below is the clockspeed that i clocked for 24/7 setting, now still using stock vgpu ( v1.05 ) , i want to find a lower vgpu for lower temperature.

1.9.0 version not recommend ?

thx bro owikh , trying now.

successful drop the vgpu to v0.987 from VID 1.050 , clock at 810/1620/2000.
furmark xtreme burn in mode 70c max, fan at 80% ( because i enable overide fan auto profile, set it over 70c will auto at 80% fan speed), 80% fan speed while gaming still acceptable for me ,compare to my old car gtx260 amp2 , temperature control really improved a lot in new gerenation gtx series card

here the proof with disable OCP


ignore the donut gone blur, because it crash after i used afterburner to screenshot.

other gtx570 user mind to share your card temperature when running furmark? wanna compare.

i think because of my fan speed is 80% so the highest temperature is not same, can you try to set at 80% and run furmark agian? i wanna see the different. thank you.

found that if use furmark 1.9.0 to stress card , no AA will hotter than 8x AA.
not sure if this same goes to 4xx series, but happen on my gtx570.
perhaps someone using 4xx series can give a try?

3 possibility
1 lack of voltage
2 overheat
3 no matter how many voltage u apply , your chip also cant get stable at that clock speed.

hmm, the psu problem i cannot answer you, cause i have no ideal what watt require by the time 560 ti overclock at clock speed 950, and u also mention MOST 560 ti can on 950mhz but not ALL right?
if card showing artifacts means not stable, or you can borrow a better psu from your fren to try it?
