There is one very, very old problem. One fine (in fact, no) moment on all farms with the Onda D1800 motherboard, the assembly stopped working correctly. If no more than 4 cards - it works as soon as there are more cards - errors that the card does not see, etc. When it broke - I can not say for sure. Once again I tried to run - I do not see the cards. It is necessary to put Hive back - there is no problem.
