Biostar released new BIOS with AGESA 0.0.7.2 for the GT8.
Though I notice no improvements really to the earlier BIOS. only a couple extra options. Some features are misbehaving the same way as earlier making it a hassle with regards to memory OC. (memory voltage is broken in combination with a few useful settings, procODT and some others)
