kepler bios tweaker explanation

[mantukis5000]

I have palit gtx 650 ti 1gb oc edition graphics card and I want to edit clock states via gpu bios. Can someone explain what GPC, XBAR, L2C, DDR(I guess it's gddr clock), SYS, HUB, MSD, PWR, DISP mean?

don't overclock with the bios on your card. Download MSI afterburn and use that. One wrong move in the bios and say goodbye to your card.
