Getting 540 MHz core clock speed in 3DMark? My GPU is 1000+MHz, so why 540MHz and also showing PCIe 1.1 instead of PCIe 2.0. What's the problem?
That's a G41 chipset motherboard, isn't it? 1.1 is the limit for x16 PCIe slots with that chipset (source, source). I wouldn't expect that to cause too much of an issue with a 750 ti though.
The 540 MHz core clock is a little more odd. Do you have a printscreen or similar of your 3dMark results that you can show?

Have you overclocked it? If you overclock it too far it will back down to the 500mhz range and stay there. If that is what happened, you have to reset defaults, and potentially reboot.
