I will gladly post in thread if there is bios level playing field. I did not try card with OCP mod yet, and tin said that you cannot short the resistor for CB but must remove it completely so i will try this afternoon and give my findings.
yes I removed it instead and works at -75c idle okay over -110 is freaks out. Problem now is even though its colder clocks are still the same limit. 1.62v is maximum or red screen and power is not stable enough to complete GT1 sooo I will retire this gtx-680 and focus on lightning
