How much hash rate i will get and it will be profitable to mine since electricity is fee
The Ram is irrelevant in mining. The Tesla K80 with 8 GPU together with Intel Xeon processor should give you enough hashrate to make a few mBtc in a day. You should install Nicehash or Minergate and let it run there if you don't want to setup mining manually which is not worthy in the long run with Nvidia cards, software like Nicehash or Minergate work well. You should not let this opportunity go away since electricity is free this is ideal to do.
what you expect what earning per day i will get
