Newest bios for your board is the bios version 2501.
Sorry for the Necrobumping but I have gone the time to flash my motherboard to 2501 and I totally regret doing it. First thing is that playing Youtube video is off like where you would jump to a certain part of the video then there would be this burst of speed like so https://www.youtube.com/watch?v=vGUPGkkqxqg.And in gaming there would be a delay of response i.e when you kill a minion/creep there would be a delay then that burst of speed which is really annoying. I have tried to reflash back to 1901 to no avail saying thats its outdatated, resetting my motherboard settings to stock speeds and even re-installing my video drivers.
