Hello,

I'm using GTX 460 and trying to OC it using MSi Afterburner. However, any change to the core clock, shader clock or voltage gets automatically reverted to a limit at 405mhz (for the cc) and so on. Memory clock doesn't revert back. I've tried running this with AB settings applied with heaven benchmark 2.5 dx11 on maximum settings and speccy shows 405mhz. This card should have a stock cc of around 750mhz. So i'm completely confused here.

plz help.

You mean everytime you get overclocking it will downclock or each time you put a load on your card it underclocks? may I see your specs? have you tried using newest 295.73 drivers and newest version of the MSI Afterburner?
