Hi,
Currently I have a windows 7 mining rig with 6x Nvidia 1060 6gb
I need to add another 2x Nvidia 1060 6gb, can I still keep my current win7 os or do I have to install windows10 ?
(I tried installing w10 but for some reason I was only getting 2mh/s in etc mining instead of 22-23)
windows 10 can run upto 8 GPUS, see this thread
https://forum.ethereum.org/discussion/14176/what-is-the-windows-10-gpu-limitCheck the following for possible cause of poor hashrate,
- Powersupplies, ensure that your powersupply could handle the 8 GPU's you mention
- Risers, faulty risers will also cause poor hashrate
- Drivers, ensure that drivers are compatible to miners
- Temperatures, heat can also degrade hashrates
good luck
