Nvidia GeForce GTX 650 Ti 1GB Graphics Card Review

We’ve seen that this reference card comes with a GPU clock speed of 928MHz on the core and 1350MHz on the memory (5.4GHz Effective), but we’re always keen to see how far this can be pushed once we get our hands on the card with some overclocking tools.

As normal, we stuck with some software that we’ve used many times before, which of course includes MSI Afterburner, Furmark, GPU-Z and 3DMark 11 which is more than enough to increase the speeds and to also check for stability.

Our usual method of overclocking a graphics card was also used today, which starts with us upping the voltage to its maximum safe level and then increasing the core clock and leaving the memory clock at its stock speeds. Once we’ve found the maximum point for the GPU clock to increase to, we put it back to its default speed and then focussed on the memory side of things. We managed to push the memory to the maximum and then had to see if both of the maximum clock speeds would increase together.

We found that we had to tweak the speeds a bit more to get both the GPU and memory clocks to work together, but ended up clocking to a massive 1205MHz on the core clock and 1600MHz (6.4GHz Effective) on the memory clock.

Achieving such speeds like this on a reference card is amazing and we can only hope to see how far Nvidia partners will end up pushing the speeds once they slap an extreme cooling solution onto the cards.
