580m THROTTLING FIX

[littleone562]

Figured this out - first a BIOS mod is needed (and already made) ONLY if you are overclocking aggressively to up the voltage on the new P1 state they that was added in the recent 580m dell vbios.

The solution: simply up the clocks on the new state (p1) to those of the max performance state (p0) because when the cards throttle they go from the p0 to the P1 state. If the P1 state is set the same clocks and voltage as the max performance state, nothing happens in regards to throttling. Using a overvolted Bios Mod I have overclocked to 850 core 2012mem and no throttling is observed because it is swapping between 2 states that have the same settings (clocks AND VOLTS). I use Nvinspector to overclock as you can overclock any state using the program and you can also apply these settings in a shortcut to multiple performance states (P1, P0) The 2 lowest performance states are still preserved so cards are still downclocking to those whenever load is low out of a game. Lastly, if you are not overclocking very extreme, the 0.85v stock setting of the new performance p1 state is also sufficient to carry a decent overclock (maybe enough to even match your performance overclock level if you are not pushing it to the limits) so no overvolting via bios mod is needed in that state. YAY!

Edit: To create a shortcut to nvinspector in which multiple performance states are overclocked - this is an example of the shortcut used to edit the p0 and p1 states as would be typed under properties - target: C:\Users\xyz\Desktop\nvidiaInspector\nvidiaInspector.exe -setShaderClock:0,3,1700 -setMemoryClock:0,3,2025 -setVoltage:0,3,920 -setShaderClock:0,2,1700 -setMemoryClock:0,2,2025

Thanks, will try this out.
