Are you guys using a modded BIOS or the ASUS Bios for the other card to get past the 900 mhz core clock and the 1300mhz memor clock limtis. I have tried to use MSI afterburner and it will not let me overclock past 900 and 1300, I have also tried the AMD GPU clock tool and it has been sucking for me, anything over 900 crashes even with a good voltage increase. I see some using ATI's overdrive and having much higher clock limits something like 1300 core and 1500 memory, can anyone enlighten me on how to do such.
