This miner is scam - it sends mysterious signals to china. No RAM for the DAG inside the miner and it uses to less energy. Or is really someone thinking it is possible to achieve over 500mh with 200w at this time? And also this mysterious start sync delay - because the chinese must fireup the rigs first 
You are a wise one, there are videos about this jasminer on YouTube and one of the popular YouTuber already started using one since the beginning of this year but I'm still curious because the miner build is just like a server, I don't understand where the 500MH is coming from or what's producing it. Very suspicious.
