New to Mining - Issue with random shutdowns
-
Good morning all,
I am new to mining and decided to start with FeatherCoins as my first venture. I’ve been mining with my GTX 970 for about 14 days now over on Blocks Factory using NSGminer 0.9.3 for 64 bit Windows and have managed to accumulate ~65 coins so far without much incident. This is my only system right now, so I set the miner to run at low intensity during the day while I am surfing the internet then set it to run at higher intensity overnight then come back in the morning to check my progress.
Yesterday morning I woke up and my miner was not running at all so I restarted it. This had never happened before, so I thought it was a fluke except now the miner is shutting itself down randomly at least once an hour, if not more.
This morning I woke up to WebRoot alerting me that it had deleted NSGMiner.exe as a virus. This was very odd since WebRoot did not flag or act on NSGMiner when I first started mining. I had to white-list and then reinstall the program. The random shutdowns are still occurring.
Anyone have any insight or thoughts?
GPU is running at 77% TDP @ 73C.
This is the .BAT file I configured and have been using:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
nsgminer.exe --neoscrypt -g 1 -w 32 -I 14 -o stratum+tcp://s1.theblocksfactory.com:3333 -O <My Login Info> -
Hi there and welcome to the forum. You’ve cured the virus false positive.
Random close downs : usually overheating.
not sure setx GPU_MAX_ALLOC_PERCENT 100 is needed, best if @Ghostlander can comment or someone with same issue.
-
Thanks,
I set a temp limit of 70C and a power limit of 77% and restarted the miner. It was running nicely for a minute at below 70C then stopped. I restarted and it was running again but just disappeared again, twice, as I was typing this. I managed to catch it stop this time - no error, window just closes.

GPU_MAX_ALLOC_PERCENT and GPU_USE_SYNC_OBJECTS are for the AMD drivers

@winter-miner Add “pause” to your .bat file after nsgminer
-
Thanks! I’ve made the changes and will see if they help. I will admit that being new to mining that so my .BAT setup was a lot of trial and error until something took.
EDIT -
Just want to make sure this syntax is OK:
nsgminer.exe --neoscrypt -g 1 -w 32 -I 13 -o stratum+tcp://s1.theblocksfactory.com:3333 -O <Login Info>
pause -
Hung a few times leaving me with a window displaying:
nsgminer.exe --neoscrypt -g 1 -w 32 -I 12 -o stratum+tcp://s1.theblocksfactory.com:3333 -O <Login Info>
Press any key to continueI just decided to brute force it for now with a Sleep 1 and a GOTO Start to it auto restarts after 1 second.

Managed to capture this error after a restart:

This link says it might be your memory?
Is the memory or CPU overheating?, use a program or test in bios.
Does it fail when some other task runs? Cnt Alt Del and run task manger.
is all memory present should be? if not re-seat it.
how much memory have you? test in software system information.
will it pass a bios memory test?,
check you have no Sata or other cables touching the memory (Due to GPU maintenance)? -
16 GB memory, just passed a 2 pass standard test with no issues. RAM is firmly seated.
I’ll keep a CPU monitor running and see what temp it reaches.
Interior of PC is clean, no cables out of place.
-
RAM @ 25% Load, CPU @ 25% load & 60 C.

What Kind of powersupply do you have? I had a simmilar issue with my gaming PC. It was operating fine for quite some time. Then I started to have power surges during intense sessions.
Your PSU might have suffered from your mining Operation, and if there was not enough headroom in Terms of Amps, it might now not be capable of Holding the voltages up.
you can try and use a Utility (like MSI Afterburner. Doesn’t matter your Card is not an MSI) to lower your power target for the GPU. Usually this makes it more Power-Efficient as well (If you devide the Hashrate/Wattage). Sure the Hasrate will go down, but you Need less Power to create each Hash. Best Thing is to lower the Powerlimit in 10% steps and leave the miner running you some Minute. Do the Hash/Watt calc and repeat until you find the max.
The most reliable scource for you wattage is a meter to plug in between your PC and the outlet. Depending on you Board, you might get some good info from the Tool “HWInfo”
Hope this helps!

Thanks, I have a 500w PSU, it is 6 years old at this point though. I set the max power to 70% last evening, no effect. At this point I think it’s probably worth building a new gaming PC then turning my old one in to a dedicated mining rig with a new MoBo, PSU, and GPUs.
-
This is the right way to go. U can choose Board with a very low power chipset (like the H-Version for the 1151 Socket) and a small Celron CPU. The CPU is “slow” but you wont use it for mining as much (i hope :smile: )
in the end you should aim to reduce the power which is used in idle. This is the amount the system will (at least) put on to of you GPU consumption.Keep in mind, that there are very efficient PSUs. It is worth etimating the required consumption and have a look at the specs of the PSU. It will have a peak efficiency in a certain area.
This way you can cut down the running costs and decrease the ROI
-
Once my new Gaming PC is built I’ll try to re-purpose my old PC.
I’m going to get a platinum rated 850w GPU but probably keep my MoBo and CPU - It’s an old i7 - 2600K so I’ll probably under-clock it. Grab 2 GTX 1060 6 GBs, and do a fresh Windows 7 install. If that does not clear it up I’ll grab a new MoBo and CPU. I can get that all done for ~$800 if I don’t need to swap out the chip set.
-
in my experience a system “randomly” shutting down usually means it’s either trying to save it’s self (eg. cpu cooling not seated correctly…computer will shutdown to protect it’s self from over heating)
If you can power it on and do stuff but it only shuts down when it’s mining, the card is drawing too much power for the PSU. For mining you want a really reliable PSU :slight_smile:

So -
Brand new system with an 850W power supply and a 1070 TI capped at 80% TPU and it is still happening.
-
weirdly I’m experiencing this problem with one of my rigs.
I’ve tested all my parts so changing the CMOS battery on the mobo is my next step
-
I’m glad it’s not just me then. I’m getting around the issue for now by looping the BAT file but it was very disconcerting to have the same issue on a 100% brand new system that I was seeing on my old setup.
-
The new NSGMiner release seems to have corrected the issue. I’ve been running now for over 24 hours with no crashes.
