Recently got some Corsair Vengeance ram, and saw it was running at 1333mhz. I went into advanced mode, and noticed there was no Ai Tweaker. So, I headed to Asus' site, grabbed the latest bios, slapped it on a USB and went to flash it when I was greeted with 'Image Integrity Check Failed'. I've tried three different bios releases with no luck. Any suggestions? Cheers.
