Well, back in December my son got a V5, locked bios with sandisk DF4064 eMMC. I just received one I ordered for myself, in early Jan. It seems to be a V4, with sandisk DF4064 eMMC, but the bios is dated 9/30/17, and what’s weird is that the bios is unlocked, but NO power limit settings for CPU configuration are available. The memory speed is configurable. ???
I guess it’s the luck of the draw.
