Need Some Help With my ETH Claymore Rig Crashing

[jonathan1683]

bounty for solving my issue 30 ZRX

Hello I am trying to figure out why my mining rig is not stable anymore. I have had it about 4 months and it has been running very stable. I am not sure what caused the instability now the only thing I can think of is a power outgage or windows update. Other than that I dont have an idea. I didn't do anything new to cause this error I didnt even catch it for a while that the PC was in a boot loop. Any help would be appreciated.

things I have done.

1.Tested each video card in claymore 1 by 1 none give any errors
2 Tests lots of cards together randomly it seems to only have an issue with the 7th card. Every time I use 7 the rig crashes.
3 Tried running different instances of claymore separating amd and nvidia still crashes at 7GPU threshold
4 reformatted PC
5. change pci slots around
6 tried different drivers
7. all this testing was done without OC on nvidia cards other than the custom bios on the AMD cards
8.changed between 16 and 20GB virtual memory
9.Tried using -gser 2

Hardware-All I got Brand new
MSI GTX 1070TI X3
EVGA GTX 1070
RED DEVIL RX580
XFX RX580
SAPPHIRE RX580
2X EVGA 1000P2 PSU
SAMSUNG EVO 850 256GB
WINDOWS 10
I3-7100
8GB HYPERX RAM
H110 PRO BTC MOBO






errors that I am getting

[damba_]

Which version of Widows are you using? Windows 10 1709 or some other?
Have you been using 7 GPU's before or did you connect 7th GPU now and it's not working anymore?
Are all GPU's connected to one PSU or have you distributed it equally on both PSU's?
By the error you are getting, it seems that somethings wrong with Nvidia drivers, but you wrote that you've reinstalled everything and it didn't help.
Try set virtual memory Initial size: 16000 MB, and Maximum size: 32000 MB since error says that Low virtual memory condition.

[Geraldo]

Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: EthDcrMiner64.exe (7912) consumed 17870532608 bytes, MsMpEng.exe (5516) consumed 109989888 bytes, and explorer.exe (3856) consumed 42541056 bytes.

As above comment said, it may relate to pagefile (Virtual Memory) Have you tried to disable Windows Defender?

as shown on your Errors Log "MsMpEng.exe (5516) consumed 109989888 bytes"

MsMpEng.exe is related Windows Defender

there's a bit confusion on the other errors posted with this

things I have done.

1.Tested each video card in claymore 1 by 1 none give any errors

5 cards detected but only 1 GPU registered, did you use -di command

if yes, Seems a single GPU also has a problem

is this the 7th GPU?

if yes, did you check or try to replace the riser?

I was also thinking on the driver changes upon win10 possible updates

sometimes mixing up AMD and NVIDIA GPU cards are too challenging to make it work with

[metr20]

looking at what you have already tried, I can only offer you to test different frequencies in overclocking + downvolt. even in this motherboard there may be problems with connecting different video cards, try to connect to different connectors PCI-E, with different connection order

Hi guys, i think i have the same problem here, mi rig is asrock h110 btc pro MB with 9 EVGA 1060 6gb cards, working without problems for months and suddenly a few days ago after a windows update it doesnt work any more, i have the same error about dag file (cannot allocate big buffer for dag) it only works if i set -di 012345 but if i activate the rest of the cards (678) it will crash, ive tried different cards and orders or tried running 5-6-7-8-9 cards and once and it will allways crash at card 7

i also tried adding RAM (i have 4 gb and installed 4 more) it didnt work, page file size was 20,000 increased to 28,000 same problem. im running out of ideas, has anyone else having the same problem??

[Souran]

I had a similar issue before, did all the "known" solutions (new drivers, check risers, check power, check overclocking profiles and even tried stock); my rig would always crash after installing the 6th card.

Anyways, It seemed to work fine after changing my PCIs to GEN 2 instead of GEN 1, and disabling CSM Support from the boot settings in bios.

Whats still bothering me is that I dont understand how this solved my issue, it just does not make sense; but it worked on multiple rigs.

In your case it could be worth a try.

Good luck

[elcoche22]

it seems ridiculous but it did work, with 36 gb virtual memory all 9 cards worked again, what I don't get is WTF is doing windows to the resources as it was working perfectly with 24, and even if I add 4 gb of ram it wont work, with 8gb ram 24 virtual it wont work, but with 4 an 36 virtual its working fine right now, thanks for the help

There is a problem with windows upgrade to 180x. under settings and update you can uninstall any update within 7 days. and by all means you should absolutely disable any updates für both windows Nd gryphics drivers until you know for sure that the update does not kill your system. stay with windows 10 release 1709 and your system will be fine...

Hello Guys,

I ended up figuring it out on my own, but the last guy is most likely right. I ended reinstalling windows 4 times on the 4th try I didn't run any updates. Everything worked fine. So it's definitely something wrong in one of windows updates.

OMG send me your addy in PM and I will still send the ZRX since you answer was the correct answer. Thanks for everyones help. Also I apologize for my slow response I thought I had notifications set up on this thread and I thought no one had replied.

My advice to you. In the future install on a computer the utility which blocks automatic updating of Windows. Even these utilities do not always help but most of time they do not provide updated Windows. In 90% you will be protected from problems with Windows. Each reinstallation of Windows is a loss of time and money. Consider switching to Linux.

[jonathan1683]

Thanks I turned off windows update as you know windows doesn't like that, but we will see how it works. I looked into ethOS and it says right on the website they do not support different drivers/cards so I didn't put much effort into looking more into it considering the OS dedicated to mining doesn't even support mining.

I had nearly the exact same error after running the August Windows update. Like many of you I spent quite a bit of time going down the Intel HD Graphics route due to the "Faulting module name: igdrcl64.dll" bread crumb. It turns out that, for me, the ***FIX*** for this issue was to increase my virtual memory from 16GB to 32GB (the same as the total memory of all 8 8GB AMD RX 570 cards divided 2). I cannot say whether it was an DAG/epoch 200 related change, Windows Update, Windows Defender, or Mercury being retrograde that caused it - but I am back up and running!

WINDOWS 10

I found the problem. You are running the wrong OS for mining.

[Mohondoa]

correct brother, don't ever update to newer version of windows 10. Because some updates will block the mining activity and the DAG created. I don't know what exactly microsoft want with the miner or crypto-world, maybe they want to more safe and stable to their system
