Thanks and I'm sorry. I wanted to as about drivers for GTX1070 on Win 7. I have 8GB physical RAM (2 * 4GB DIMM). But basing on your answer I think it does not matter in acase of Win 7 if I use 1070 or 1080. I have problem that my mining speed decreased and decreased each time. Only power limit increasing fixes it, but it costs additional electricity. If I will use win 10 I will not have these problems? Or may be it will be better to use HIVE OS (If in any case I should install other OS instead of Win 7)?
No, unfortunately the same problem is present in Windows 10 and Linux. Unless Nvidia solves it at driver level (e.g. increase the size of memory pages like AMD did with Polaris), which is highly unlikely, there is no fix for this problem.
Thanks for the clarification! Installed the latest driver and it worked!
Note that you can use the
latest supported by PhoenixMiner Windows driver, which is 20.4.2 for PhoenixMiner 5.0b. The new driver 20.5.1 won't work with PhoenixMiner 5.0b and 4 GB AMD card.
