Hello everyone,

So I have been trying to overclock my GPU for a few days now, and I have noticed a discrepancy between what my GPU Tweak lets me do, and what others say about the card.

The main concernc is the voltage, on many forums/guides/reviews I read that the card should handle going up to 1.3V, stock being 1.2. The interesting thing is, in my case, the slider tops at 1256mV. Is this due to the PSU or is it something that is locked in the card?

BR,
