Hi guys, I just recently bought an VTX 7870, i am having problems with overclocking it, the core clock is 975mhz and the memory clock is 1500 by default, the core clock runs at 925mhz in game, when i decided to overclock i changed the core clock to 1000mhz and the memory clock to 1550mhz but ingame its still running at 925mhz, when i first start up my game it runs at the overclocked setting but only for like 2/3 seconds, i have tried this in both in MSI Afterburner and CCC, anyone got any advice that may help me out?
