To all of you that are mining with the ASUS B250 Mining Expert motherboard a new BOIS has been released.
BIOS Update 0403 released 12/15/2017
ASUS claimed that there would be a BOIS update in 4Q2017 to unlock the BIOS to support more than 13 GPUs (8 Team NVIDIA+5 AMD or 8 AMD and 5 NVIDIA) on their 19 PCI board, but this is not it....
This update has has no documentation and cites in the description:
B250 MINING EXPERT BIOS 0403 Improve system Stability;
I have installed this update on my 2 x ASUS B250 Mining Expert systems and have not noticed much of anything...
Looking at my hash rates overtime, I think the system might be a bit more stable but only time will tell.
