Guys, I still have the freezing problem. Even with different motherboards and different usb's.
Rly the only solution is to get an ssd?

Hello there. I must say- Amazing stuff here.
Just had a one question. My Riggs sometimes restarts and when they do, after restart they enter in bios because the USB isn't recognized. I have to manually replug USB and then it boots up again.
I have a AsRock h110 BTC+ board and a 3.0 16gb usb stick

If you haven't tried this already, go into bios, under the "Boot" tab you have setting for "Fast Boot", set this to "Disabled". You can also increase "Setup Prompt Timeout" to 2 or 3 seconds. If that doesn't help you would have to try another USB stick (or buy the cheapest SSD).

So, is it freezing problem or is it system not detecting USB stick when it restarts, or both?
Have you tried the bios settings that I suggested?

Now, about the freezing... (which would eventually trigger the watchdog to reboot the system...). If it haapens with different motherboards and different USB's, getting a SSD wouldn't help much if something else is causing the freezing. There are few things that could cause freezing (most common):

1. excessive overclocking - reduce overclock, increase power limit
2. bad risers - replace riser
3. power strugle - make sure you don't draw more than 80% of the listed power supply rating; don't connect more than 2 risers to one SATA cable (eventually 3 for for 1050's and 1060's); check for loose connections
4. bad GPU - disconnect one by one to troubleshoot
5. bad USB stick or slow USB stick - replace it
6. bad bios setting - load default/optimized settings, enable 4g, set to (Gen1 or Gen2), disable on-board video
7. bad/damaged image of nvOC - reimage
8. bug in nvOC - update to the latest version

Give more details, error messages, screenshots, OC values. It's not easy to troubleshoot blindly

These are excellent troubleshooting suggestions.

Please post your full rig component list (plus if using multiple PSUs how they are used / if they are joined / if they are connected to the same circuit) , the mining client / coin selection you are using.

Ok here it is. Yesterday all my rigs went bananas and froze one by one with an aprox. 1 hour gap.
1)First Rig was : Asus Mining Expert motherboard / 8gb Ballistix RAM / 13X Asus Dual GTX 1070 / 3 PSU's - Into the Motherboard (2800w psu, 730w psu, 730w, psu) / CPU - intel celeron g3900 / SSD - Kingston 120gb / Risers - 006c. / Mining Zcash with 3_4 /** Maybe you know something about this motherboard, it just doesnt turn on with more than 13 GPU's. So I'm stuck with only 13. Just shows Black screen and I am forced to shutdown**

2)Second Rig was : Asus ( I cant remember The model, but it was lga 1151 with 5 PCie slots) / 4X GTX 1060 6gb / 1X MSI p106-100 Minning / RAM - 4gb Kingston / CPU - intel celeron g3900 / Runs USB 3.0 16 gb / PSU - 1000 w EVGA / riser - 0006c . **This restarded After I remotely switched it from mining eth to zcoin and it restarted and did not boot up.**

3)Third Rig was : Motherboard AsRock h110 BTC + / RAM : 4gb Kingston / 10X GTX ASUS DUAL 1070 / 1X GTX PNY BLOWER 1080 ti / CPU - intel celeron g3900 / SSD - 120 gb Kingston / PSU - 2800 w paired with 730 w psu directly into motherboard (paired with the special 2in1 psu cable) / Risers - 0006c / Mining Zcash with 3_4 / **No clue how it went down, but It just froze up screen.

4)Fourth and the last went down this : AsRock h110 BTC + / Ram : 4gb Kingston / 8X GTX ASUS DUAL 1070 / CPU - intel celeron g3900 / SSD - 120gb Kingston / PSU - 2800 w / Risers - 0006c / Mining Zcash with 3_4 **Just froze up just like the 3rd one.

Last man standing was Motherboard : TB250-BTC+ Ver. 6.x / RAM : 4GB Kingston / 8X GTX ASUS DUAL 1070 / CPU - intel celeron g3900 / SSD - 120gb Kingston / PSU - 2800w / Risers - 0006c / Mining Zcash with 3_4

PS. Could you possibly drop in some Guide how to configure nvOC for ZCoin?

pss. My restartlogs for 3rd rig Sun Oct 1 20:03:39 EDT 2017 - Lost GPU so restarting system. Found GPU's:

Unable to determine the device handle for GPU 0000:0F:00.0: GPU is lost. Reboot the system to recover this GPU
Another update: Just while standing besides rig, It went tick that kind of noise like a power on sound and all cards stopped working.
My clocks for everything is 100 core 500 mem

Here is a screenshot from wdog

I recommend using a g4560 or better CPU when using more than 7 GPUs. I would get a g4560 or g4600 and swap it with one of your celerons in your 1st or 3rd rig. If this solves the problem; I would upgrade all your rigs CPUs.
