Is this too much?

post #1 of 7
Thread Starter 
So I've been playing with my Classified to see if I can hit ~1300Mhz. At stock Classified voltages I was being underclocked to 1150Mhz when I had the GPU offset set to +140 Mhz. I've upped the voltage to +25mV on top of the out-of -the-box voltage that I got with the card. I'm using K-Boost and with the overvoltage I can run 1293Mhz nicely, I've not tried to clock higher.

Is this too much considering the voltage the card was set at stock? The voltage meter looks pretty insane to me, but I have no idea what the stock voltages are.

I can only assume VDDC is my voltage core voltage on GPU-Z?

Yes, that is core voltage. For 1300MHz or 1350MHz+ you will likely need more voltage.
