Hi all, sorry I'm new to this OC thing. Just got this card, according to Gigabyte, this model has a max boost clock of 1797 Mhz in OC mode. However using Gigabyte Game Xtreme Engine as well as Afterburner, the card both show clock speed 1898 Mhz out-of-the-box without any clocking, during benchmarking with Uni Heaven. Is this normal or are my softwares not monitoring it correctly? I can't seem to be able to put this card into OC mode either. Xtreme Engine cannot select OC. In Afterburner, I raise the GPU power limit to 108% yet I see no difference, still 1898 Mhz max...
