no way?

Well, I thought I had my crashing issue taken care of.. But nope!

Rig crashed at 1A.M and actually restarted and started running. That was a first. It usually get's hung up, teamviewer crashes so I can't see what's on the screen and the fans on all the GPU's stay running until I manually re-boot.

Rig has crashed twice today since then. Once, the "MANUAL FAN" control was set to ON in the 1bash with the the setpoint to 60.. I had this turned off and was running AUTO fan control.. No clue how this was changed as I certainly didn't do it.

I have telegram setup, it messages me when the system boots up. But when this freeze or whatever is happening I get no message.

13 - PNY GTX1070's
ASRock H110 BTC+
850W EVGA PSU running Mobo and 6 risers
2 - 1400W HP server PSU's splitting the remainder of the cards risers
Pulling 1,810W at the wall so I know it's not a power issue
Power Limit - 125
Core - 100
Memory - 475

I have logging turned on, with clearing every 3 hours. But when I re-boot, there is no log so I can't see what the issue is.

I was having the following issues before.

- Unable to determine the device handle for GPU 0000:0F:00.0: GPU is lost.  Reboot the system to recover this GPU
- GPU Utilization is too low: restarting 3main...

When it's running, everything seems to be running just fine. Temps are good, fan is between 60-75 per card. Hash rates look good. I just don't understand.

Just two per PCIE off the EVGA.

New alert came through after re-flashing the drive that GPU 12has fallen off the the bus - GPU 12 is not responding.

I’ve tried switching the riser and GPU with no resolve. 

Victony GPU risers 6 pin

Running 13 GPU from 3,650W worth of power, 240V at 1,810W.

Two parallel miner PSU's with X11 breakout boards connected via 4 pin connector to the mobo. I should have plenty of juice, maybe a hardware issue.

I think an 80 plus platinum PSU efficiency is around 92%
6x120 watt is on verge of your PSU limit and it's natural to give up and lose GPU.
Either lower your power limit or use higher PSU

I think there is some confusion here. Only 6 risers are powered by the EVGA. ALL cards (6+2) are powered by the 1400W PSU’s. 7 (6+2) on one 1400W, 6 (6+2) powered by the other 1400W. The X-11 breakout boards are connected via a Molex to the mobo so all PSU’s power on/off at the same time.

But should't watchdog be restarting the rig on any error? It's seems the GPU crashes and it freeze's crashes the OS as well.

Power limit is set to 125W, so essentially 85%. Core 100, Memory 475.

Rebooted the rig due to this error at 10PM, it's now 11AM and all is fine with no settings changed. The only difference is that Quake isn't opened (when the rig boot's only terminal opens and start's mining) but I usually open it to view what's going on. Obviously it is running in the background, but this is just not consistent at all so it's difficult to pinpoint.

In an attempt to maximize hashing returns, I'm trying to use SALFTER_MPH autoswitching instead of the WTM one

The issue I have with it is that it jumps too much between similar coins. This results in pool hopping and difficulty readjustment on each hop. To counter the problem, I have set a long delay between checks.

Is there a better way to set it up, and to maximize the profit ? I'm using 1070s here.

Hi All,

I am trying to use zpool's multialgo switch with nvOC but don't seem to get my head around the configuration. Do I need to type "Zpool" in Coin portion of configuration and where can I mention multi algo for zpool switching? I would appreciate if someone share the configuration file or exmaple.

Thanks,
