Claymore Miner / Ethereum Mining Issues

[ErikETHMiner87]

Hello everyone,

I hope I can find a solution to this problem here, it seems that I am not the only one that has gone through this. (I have yet to fix with solutions I've seen so far)

First I will show you what I am running so far:

Windows 10 Home 64 Bit OS
1 Gigabyte GTX 1070 WINDFORCE OC 8GB  (4 others on the way, so I'm freaking out) - It is on a powered riser.
1200 W EVGA Titanium 80 Plus PSU Fully Modular
MSI Z270 A PRO MOBO
Celeron Processor
4GB DDR4 RAM
64GB SSD

My rig starts normally and begins to mine with no issues ,  then either 40 minutes later or 2 hours later the computer crashes and shuts down completely.

Error Message in red text:

NVML: cannot get current temperature, error 999 (an internal driver error occurred)
Cannot resolve 'eth-us-east1.nanopool.org'
ETH: Stratum - Cannot connect to eth-us-east1.nanopool.org:9999
DevFee: ETH Stratum - Failed to connect, retry in 20 seconds...
ETH: No new jobs were received for 10 mins - something is wrong with pool
Cannot resolve 'eth-us-east1.nanopool.org
ETH: Stratum - Cannot connect tp eth-us-east1.nanopool.org:9999
ETH: Stratum - Failed to connect, retry in 20 secs...
WATCHDOG: GPU 0 hangs in OpenCL call, exit
WATCHDOG: GPU 0 hangs in OpenCL call, exit

Things I have tried:
1. Switched powered risers on the card
2. Re-installing NVIDIA drivers to the latest version including CUDA 9.1
3.Updated MSI BIOS
4. Kept OC settings to default.

Please if anyone out there has fixed this issue any help would be much appreciated I am completely stuck.

Looks like a DNS issue resolving the pool address. You can try using another DNS server like Google's (8.8.8.8 and 8.8.4.4) or connect to the stratum IP address directly.

eth-us-east1.nanopool.org: = IP Address : 142.44.243.6 and 192.99.69.170 and 142.44.242.100 and 144.217.14.139 and 144.217.14.109

You can type in the cmd the "ipconfig flash" and ipconfig renew it's the same issue sometimes happen to my rigs, but sometimes you need to turn off and on your router

I'm currently running into this issue with my rigs. I noticed it first on my home computer and did the router reset and that didn't work. I am in the process of changing the DNS server info on all my computers. After some research I saw a million negative comments about my internet service provider having issues with there DNS servers or something and this was the recommended fix.

I plan on changing the settings over the weekend. As of right now my rigs and computers are not having this issue but I don't want it to happen again cause it always happens when I am away from working on them.

As long as there's Google, no reason to be ignorant.

You can also replace the stratum address with the IP address in the miner .bat or config file.

Hi there ,

So I tried the two solutions you provided and everything seemed to be working fine until the rig crashed again and shut down automatically.  (Thank you Vann for trying to help)

It mined for over an hour and half then shut down.

I received these error messages from Claymore:

NVML: cannot get current temperature, error 999 (an internal driver error occurred)
WATCHDOG: GPU 0 Hangs in OpenCL call, you need to restart miner 
WATCHDOG: GPU 0 Hangs in OpenCL call, you need to restart miner 
ETH: No new jobs were received for 10 mins - something is wrong with pool


Also when I put in the IP address for Stratum to  connect to the US east server , all the IP's lead to US west servers (not that it would be a problem but it seems weird since I put in IP addresses for east coast)

It seems to me (perhaps I am wrong) that claymore or nanopool is having some issues..

Would anyone reccommend dumping claymore/nanopool and going to another miner/pool ?

Does anyone have a fix for this issue? Please help anyone!

Hello,

For your NVML problem, you can try to add this arguments in your launch script : -tt 0   <=== This will disable fan and temp monitoring (readme in claymore folder), this saved me for a couple of weeks, but the problem is appearing again after, due to a bad riser (see below).
This problem can be found when you have bad risers (quality, brand, type [SATA|MOLEX|6PIN])

Assume a riser is weak and bad when you receive it, no matter what price you put in (one brand gave me 5/6 riser that wasn't working, another brand got me 11/12 good risers and one that was broken (physically))

Hope this will help you, have a good try on it

Change pool, try ethermine or another one. If the same happens again it is your hardware and probably a power issue or a overclocking issue.
