Can't get above 1202MHz on GTX 670 (OC)

I have a Gigabyte GTX 670. When using Precision X to overclock the max I can get is 1202. It's stock boost is 1100MHz. Is there a way I can go above 1202? If I put the core offset at +92 or +125 it still only goes to 1202MHz. I have the voltage settings maxed out (1.175)

Any idea why it caps at 1202MHz? Is the voltage holding it back?

Thanks,
JOe K.

Funny, that's the guide I used. It's weird that it levels off after 92. +105 gives me the same values as +92. I crash about +110.

Non reference cards generally wont overclock much higher than stock atleast on air. Make sure your power setting in the Nvidia control panel is on performance this will lock the card @ its highest frequency with out boost, it makes it way easier to get stable settings also make sure power limit is maxed out, lets it draw more current under load.

Is 1.175 the max voltage available? Also, if I lock at highest frequency that's just for testing correct?

Yes 1.175 is the max you can go Nvidia decided to lock voltages down on kepler to prevent RMAs, for air you should keep voltage at stock though unless your using EVGA K Boost because the drivers will prevent you from hitting boost clock if your temps are getting too high. Make sure your power limit is all the way up in precision x and you should see the GPU boost go a little further. Your pretty close to the max your going to get out of it though with the current drivers, I can do 1241 stable clock 1627 memory or 1300 not stable with a much smaller memory offset.

If I'm close to the top then I guess, I'm satisfied with that. I am at +92 and +300. I could probably go higher than +300 mem but I am not patient enough to look for graphical glitches. Crashes are much easier to monitor.

Nvidia implemented the GPU Boost feature on the new Nvidia GeForce 6 series GPU’s of the Kepler Architecture. This allows the card to have a base clock and it adjusts dynamically or overclocks to a speed of up to a certain amount depending upon the thermal and power envelope. This makes Overclocking these cards a bit different as you now are overclocking with a boost clock and by offsets from the out of the box clocks.
