i got a very strange problem.low hashrate on hiveos than win7
i used 4*gtx 750 to mine xmr and the hashrate change from 700h/s to 880h/s,the miner soft is xmr-stak.
while i use win7 the hashrate just from 860h-880h.the miner soft is xmr-stak,
Take a look at the Nvidia.txt config file that was used on Windows and compare it to what HiveOS generated. If HiveOS's Nvidia.txt config file is different you should put what Windows generated into the override field for HiveOS XMR-Stak.
Also, on Windows were the GTX 750's overclocked?
I have 24 GTX 750's installed as 8x GTX 750 on each of my three HP DL580 G7 servers. Even though all 24 GTX 750's are the exactly the same their hash rate varies from 221 to 250. The hash rate is steady for each GTX 750 it is just that one will produce 221 H/s and another will produce 250 H/s. The only thing I could guess at is that the memory speed on some is faster than others. On average these 24 GTX 750's produce 232 H/s each.
This is my Nvidia.txt for eight GTX 750:
