I have been going through all the version through, until 1.8.4
and it's rock solid. haven't had a single reboot or crash since then, and still at a higher hashrate than with the original 1.4

Hello,
i added a 3rd 1080 Ti GPU in my rig. (H110 Pro BTC+)
but it stopped booting from the USB stick i use. i just hangs after the bios with the "B4" code written in the bottom right of the screen.
does it mean i have to switch to a HDD or SSD  for it to work now ? or do i need more than 4 GB of RAM ?
