Hi guys I need help I am so tired first thanks for reading this , for the last two weeks I have been balancing between taking care of our 4 months daughter , Job and setting up my rig.
My rig consists of
4 GTX1070 ,
windows 7 ,
8 GB RAM ,
core i7 6700 ,
MS170A GAMING 5
Seasonic PSU of 1250W
At first I could not get the cards to read through the PCI USB connectors so I have two cards connected on the motherboard and two connected using the USB connectors making a total of 4 cards ,
I followed this guide Installation guide. during installation.
The issue I am facing is every time I start any miner software Nicehash , Claymore , EWBF´s Zcash miner for mining z.cash I get an error from the mining software for nicehash for example the mining machine freezes for hours.
Nothing moves no stats nothing , even the computer clock ,it freezes I have to restart it by unplugging the power cable.
This is the behavior of nicehash miner which when I restart I get a screen that shows broken windows operating system repair screen like this…
After restoring the operating system back , the clocking on the graphics cards gets lost and it’s the default setting for all the four cards that gets loaded it is set back to stock setting.
I also wish to add that I am using the ** MSI Afterburner for overclocking**.
For other mining software for example EWBF´s Zcash miner the computer follows the same pattern after mining for approximately 2 hours on stock settings before crashing and giving this screen below
and it doesn’t even to start mine on the cards if they are overclocked or undervolted. It gives the above screen
In all the situation I can’t mine with any available zcash mining applications for more than 2 hours before I get a blue screen , crashes the graphics or freezes the machine.
At first I thought the problem is the drivers so I updated to the latest drivers from nvidia site , this made things even worse I downgraded to and it performed better.
I also ruled out the possibility of a messed up graphics card as all the cards tested individually are doing great.
I also ruled out the chances that the power is not enough because if it weren’t enough I couldn’t mine for a while before the windows 7 crashes.Here is a screen shot of mining with nice hash and the power consumption per card.
Let me add that the above stats are from graphic cards that have default settings.
I am using the connectors below…
Thanks for taking the time to read this and looking forward to hearing all suggestions.
