Ah!

Windows 10 Professional

All settings are factory default - I did not tweak anything.

Hello there!

So I recently added a 2nd PSU to my rig in order to be able to add an additional video card.

After any reboot, I literally have to scan for new hardware in order for additional card to show up. Is there anyway to make this auto detect or force scan new hardware after a reboot?

My hardware specs are:

     Asus Prim Z270-P Motherboard
     Celeron CPU
     16GB RAM
     2540GB SSD
     1500 Thermaltake PSU with (4) EVGA 1080tis on it
     750W Thermaltake PSU with (1) EVGA 1080tis on it
     (1) PSU Jumper cable connecting both PSU to the Motherboard


Everything is stable about the rig *except* for auto detect of the 5th video card.

I just want to avoid having to manually scan for HW to bring up the 5th card...

Thank you in advance!

Hello there!

I am looking to build Ubuntu 16.04 with (3) EVGA GeForce GTX 1080 Ti's for starters (plan to add one more) to mine ZCash using EWBF Miner.

I have already performed the following with little success:

     Asus Prime P270-P  Motherboard
     1350Watt PSU   
     16GB RAM
     240GB SSD
     Base Ubuntu Server build
     installed CUDA 9.0 as per instructions here-=> https://developer.nvidia.com/cuda-downloads
     installed 1080ti drivers from NVidia version 384 (latest long term release)
     installed EWBF Miner 0.34b


Once I installed CUDA 9.0 the following command did *not* work:

     nvcc --version

it recommended i install "sudo apt-get install cuda-toolkit" of which installed version 7.5

     nvcc --version *did* work

However when running the actual EWBF Miner the GPU temp would be zero and the miner would freeze up.

Does anyone have a fail-safe guide or step by step to use in order to get the a succesfull Ubunut miner?

I have have plenty of issues with Windows and was hoping to get a plain vanilla Ubuntu minig build.

Thank you in advance!

Thanks! I will give it a shot!

Here is the latest:

I swapped out out existing risers with new ones. I had an unopened 6-pack of risers that I was saving for my next rig.

I then Only had (1) 1080ti plugged in and its works *perfectly* on its own without issue. In this state it was GPU #0.

I then plugged in the second 1080ti *also* with a new riser and only mined with this one. I set the configuration to only mine with the second GPU which came up as GPU #0 it too worked well on it's own.

I then kicked off in a separate window another instance of the EWBF Miner and specified only to use GPU #1 so GPU #0 and GPU#1 were both running in separate mining instances.

At that point VROOOOOOM!!! - the fans on GPU#1 spun up at 100% and the computer would become unresponsive but the fan on the GPU #1 still keep spinning at 100% until I forced a shutdown of the box.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

So I am still perplexed but am also leaning towards a PSU issue.

I did look through the Event Viewer and did see this:

     Several of these:  "The system has rebooted without cleanly shutting down first. This error could be caused if the system
     stopped responding, crashed, or lost power unexpectedly."


     "The previous system shutdown at 8:16:18 PM on ‎12/‎7/‎2017 was unexpected."

I then forced both GPUs to mine and here are the Event Viewer entries:

     "The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000124 (0x0000000000000000,
     0xffff8001358458f8, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\Minidump\120717-
     8812-01.dmp. Report Id: 9d4fd139-4e1a-452b-ab24-d8f725a52999."

AND

     "A fatal hardware error has occurred.

     Component: AMD Northbridge
     Error Source: Machine Check Exception
     Error Type: HyperTransport Watchdog Timeout Error
     Processor APIC ID: 0

     The details view of this entry contains further information."

Any ideas?

overclock and power levels ?
No overclocking at all - all defaults

miner logs of the crash ?
I set the flag to capture log files but the miner is not creating them...


did you tried swapping out the risers to see if you don't have a bad one ?
I will do that next - I am now troubleshooting with the known good card and it still crashes

how do you power the gpu ? (how many cables, do you use Y cables)
I have (1) 8Pin power cable and (1) 6 Pin power cable in each 1080ti

did you power the risers properly ?
can you please elaborate on this one?
I have the card plugged in to the rise then the 4 pin molex cable is connecting to the rise - the other end of the molex 4 pin is the SATA connector which is plugged in to my PSU thent he USB cable is cabled between the PCI-E slot and the riser. Did I miss anything?

did you power the motherboard properly with the added molex connectors ?
Everything with the computer works great until I start mining.

does one GPU work (one or the other) ? when you put back only one ?
I am now testing with 1 GPU and is still does crash. I also received an

Prob a bad idea to mix up AMD & NVIDIA on the same rig, but i don't think that's your problem anyway.
This is why a rebuilt entirely and now only want to focus on the 1080tis

On a side note, that's way too much SSD & memory, 8GB memory and 128GB SSD would be enough, cpu too powerful too. But that's another matter.
ok


You may also want to increase the virtual memory, make it 16GB start, and 64GB top, it will allow you to run all known algos. (16/32 would do fine too except for a very few niche one like SiB)
I increased the paging file to 32GB

Hello there!

So I recently received (2) EVGA 1080ti cards and have mixed results.

On my initial attempt I had cards working with the EWBF ZCash Miner version 0.3.4b.

The cards were mining overnight without issue and getting between 650 to 720 Sol/s.

I then decided to add my Radeon 480s on the same rig one at a time until I thought they were stable with a half hour between adding each card.

After adding my third Radeon RX 480 It started crashing. Both the Claymore AMD miner AND the EWBF Miner.

I then decided to remove the Radeon cards from the mix and simply mine with the EVGA 1080ti's.

I was never able to get them functional again to the point where I reinstalled the OS from scratch and STILL was unable to get it working.

I even then looked at other miners with the only success being the excavator_v1.1.0a_Win64 miner.

I let this run overnight and now that too doesn't want to work.

Basically once the miner initializes the screen will blank out and one of the cards fan will spin very high while the other card is idle.

Does anyone have any advise on how I should troubleshoot this?

I am at the point where I just want o go to a Linux build in hopes of getting better, more stable results.

Please advise! Any help is appreciated!

My hardware configuration is as follows:

     BIOSTAR TB350-BTC AM4 AMD Motherboard (6) PCI-E slots
     16GB RAM
     AMD A6-9500 Bristol Ridge Dual-Core 3.5 GHz Socket AM4 CPU
     240GB SSD Hard Drive
     Enermax Platimax PC 1350 Watt PSU (Power Supply)
     (2) PCI-E risers
     (2) NVidia EVGA 1080ti SC2 card

On Windows 10  setup a (16) GB paging file.

@Vann - that was it!

I had thought I patched all my AMD cards but that wasn't the case!!!

Thank you very much!

Hello there!

I so did get my EVGA 1080ti card in today and tried to mine with the existing (5) AMD RX 480s and new (1) EVGA 1080ti SC2 card.

I did disable Windows 10 automatic driver updates as a precaution so I could control which drivers were installed.

The driver installed fine and the OS did see the new EVGA 1080ti card.

HOWEVER, only (3) of the (5) existing AMD RX Radeon 480s were detected as GPUs and (2) were NOT detected as GPUs. They showed up in Device Manager with the yellow triangle exclamation marks.

All (5) were detected, however on the (2) that are not functioning from Device Manager it says:

     "Windows has stopped this device because it has reported problems. (Code 43)"

I read elsewhere that I should try to update the driver manually on the ones that didn't show up as GPUs and is still had the same result. Windows said everything was fine with the drivers.

The Motherboard does have a "mining" feature which is indeed set to enabled.

My current hardware configuration is:

     BIOSTAR TB350-BTC AM4 AMD Motherboard (6) PCI-E slots
     16GB RAM
     AMD A6-9500 Bristol Ridge Dual-Core 3.5 GHz Socket AM4 CPU
     240GB SSD Hard Drive
     Enermax Platimax PC 1350 Watt PSU (Power Supply)
     (6) PCI-E risers
     (6) AMD RX Radeon 480 cards
     (1) NVidia EVGA 1080ti SC2 card

Any advice/suggestions welcome!

Thank you in advance!

I will give that a shot!

So since the overhead is actually on the GPUs and not the OS fro mining then this should work.

Makes sense!

Thank you all for the responses!

jmigdlc99,

Thank you for the reply!

My question was specifically towards ZCash miners that would be bale to support both AMD an NVIDIA cards.

From all my research I can only find miners for ZCash that only support AMD or NVIDIA, not both.

My current setup is all AMD RX 480's but I have been having issues getting my hash rate up so I was hoping to get an NVIDIA 1080ti which has a superb hash rate but it would be pointless unless I had a miner that supports both AMD and NVIDIA cards for ZCash similarly to the ETH example you provided.

Hello there!

From what I can see I can only find either dedicated AMD or NVIDIA card ZCash miners.

Does anyone know of an mining software that can leverage both AMD and NVIDIA cards on the same rig?

Thank you in advance for you feedback!

I just recently started mining ZCash and provided my ZCash address to the pool.

I found out *afterwards* that JAXX does not want you to use their wallet for mining.

I panicked as I was nearing my first payment from the mining pool and can confirm that my transaction *did* indeed come through successfully. However, being that JAXX do not want it used for mining.

I created a cryptonator account and will be using them moving forward - they seem like a better option.

You can transfer funds within the sire and they also have two factor authentication which JAXX lacked.

I wish they had made it more obvious to the end user that JAXX should not be used for mining activity. That has a huge impact!
