MSI Afterburner doesnt apply when I overclock?

[zenzu888]

Hi, I Have an MSI gtx 460 that currently has 780 MHZ. I overclocked it with the MSI afterburner to around 820MHZ clicked apply, however when I opened GPU-Z it still says im at 780 MHZ? Is this suppose to just say 780 MHZ while it is overclocked?

I may have found the problem, whenever I start MSI Afterburner or hit ''Apply'' it shows this error on the bottom right.. ''Display Driver stopped responding and has recovered, Display driver NVIDIA Windows Kernel Driver, version 260.99 stopped responding and has successfully recovered''.. Anyone?

It means that the overclock was too aggressive/unstable so it reverted back to its default settings.
