I got my BK-G28 delivered yesterday. I have it up and running on Skein but am only getting 12 GH/s poolside instead of 14 GH/s advertised; tried two different pools so far.
Baikal Miner Web UI is useless for checking actual hash rate and it just seems to display a dummy number per card no matter what. Case in point: one of the hash-boards on my BK-X10 is seemingly dead 2 months after ordering, and the web UI still shows 1.746 Gh/s for the board and 3 boards for 5.238 Gh/s total; just that it shows 0 accepted shares on the faulty board. Pool-side shows around 3 GH/s because of the broken board despite that Baikal Web UI shows 5.238 GH/s
It seems BK-G28 behaves similarly and shows the hardcoded advertised speed of 2.028 Gh/s per board for 14.19Gh/s total no matter what. Either that; or my broken board on my BK-X10 IS still hashing at 1.76 GH/s and it's reporting correctly and just for some reason is getting no shares.
