Unlock Voltage (and PL) on a GTX 670

post #1 of 2
Thread Starter 
OK, I used kgb, I flashed the bios with firestorm, and now I have the limit to 150, and the voltage and frequency in game go to 1.21v/1228: not stable in Unigine Heaven.

Now I ask: why is not stable? What can I do?

Furthermore, my intention was different: I just wanted to raise the upper limit to 150 (and that I got it) and "unlock" the voltage (to be able to set it to 1.21 only when I wanted to do when I wanted to use an OC or OC profiles. ... not always, fixed whenever the GPU is put under load).

I want my own current settings:
Voltage: 0.98v idle / full load 17.1
Frequency: 940 base/1020 boost/1110 kepler boost
all for incredible:
PowerLimit 150% (obtained already with kgb)
Voltage: adjustable from msi afterburner to 1.21v at full load


I have this situation in default (no bios mod)

Voltage: 0.98v idle / full load 1.17
Frequency: 940 base/1020 boost/1110 kepler boost

If I increase the voltage in msi ab, this is not applied in practice the voltage is locked.
So I would like to unlock the change of voltage, in order to create profiles where I can set the voltage to 1.21 (but only in those profiles).

But with the procedure by kbg, I find that the default voltage rises to 1.21 at full load (always)

You are just going to have to do it manually. Be thankful you even unlocked voltages on that card. I recently unlocked my voltages for my GTX 770 up to 1.300 and I'm running at 1.225 @1320Mhz core clock. I also have to remember to press reset in AB so they dont run at 1.225 at idle. Im not sure what can be done about that, but who cares really...
