Now for a couple of days I've been using XMR-Stak with my dual core DL385P and it sees to work just fine. Just one small problem, every time the difficulty gets above 32000 the miner takes to long to give an answer to the pool and the connection get dropped. The miner comes back at a lower difficulty and in time it raises up to 32000 again. The hole cycle starts again (connection drop, etc etc)

Is there a trick or option to tell XMR-Stak never to go higher than 30000 ?
