I have a Galaxy GTX460 768mb GC Version. The card is factory OCd(675mhz->700mhz core I believe). The problem that I'm having is that any program I use can not actually get the clock to jump up, even when I click apply. Sometimes it will jump for a minute and then go back down to the stock 700mhz. I'm thinking that because it is factory OC it may be locked or something. Any way to unlock it?
