1  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN] T-Rex 0.6.6 Nvidia GPU miner (Windows & Linux) on: September 16, 2018, 01:50:03 PM
New version released.

0.6.6
Speed improvements: bcd - 5%
Cosmetic change: the miner will not show duplicate hashorder messages for x16r/s, bitcore, and they are no longer labeled as WARN
To disable API altogether set --api-bind-http / --api-bind-telnet to 0.
HTTP API: new control command "shutdown" to quit the miner (see help file for details)

Hi, if I use the telnet api, is there a way to get the same details as with the JSON option?

miner@miner:~$ netcat localhost 4068

It doesn't work on a Titan X without p (Windows 10). Is that intended, because the Titan X also uses GDDR5X like its big sister Titan Xp? I have also tried the revA parameter, but without success.

Hi,

thx for the github project, works like a charm. Smiley

I have a few questions, maybe someone has an answer to it:

- I want to connect 3 relais boards (2x8 channel + 1x4 channel). I have connected the 2 relais with 8 channels to the 5v pins of my raspbery pi and the 4 channel relais to the 3.3v pin. The relais are all 5v, but I've connect the 1x4 channel relais to the 3.3v pin and it also works. Is this dangerous, or is it ok, to connect a 5v relais to the 3.3v pin?

- I have read somewhere, that you should use a resister between PI and relais boards, to limit the current. Is this really necessary?

- Some LEDs on my relais boards are lit very dim at startup and stays at this level. I think this is because of the default GPIO levels, after startup of the PI. If the relais is swichted one time, the LEDs are dark. Maybe you should initialize all the pins, at startup to LOW voltage state.

  While running a check on my ETH payouts on EtherScan today , I noticed that a transfer from someone of a token for
ZENON worth 79.00 was sent. I have no idea of what this is or why. Can someone enlighten me on what it means?  I am
just mining coins and happy at that. Not really into the buying and selling end.

thanks    thay


Sometimes some coins make an airdrop to random addresses.

Guys can you help me please
My rig has been crashed and couldn't reboot itself
this was last message
Code:
     
GPU_COUNT:  13

GPU UTILIZATION:  Unable to determine the device handle for GPU 0000:0B:00.0: GPU is lost. Reboot the system to recover this GPU
Sun Nov 12 12:24:15 EST 2017 - Lost GPU so restarting system. Found GPU's:
Unable to determine the device handle for GPU 0000:0B:00.0: GPU is lost.  Reboot the system to recover this GPU


Sun Nov 12 12:24:15 EST 2017 - reboot in 10 seconds

It has happen few times, since I was away from my rigs
it cost me massive down time
Eventually it was power cycled and manually rebooted


Is it because OC (gtx1080 pl150 cc0 mc600)?
or something else
 Huh

I have the exact same problem with my rig, but it picks a card at random to "lose".  I've replaced all the risers and usb cables and still get the same problem.  I thought it might be power related, but I am only at 550w each on my 2 x 750w power supplies.  I still haven't been able to figure it out.

I have the same problem. In my opinion, the problem is, when a GPU falls of the bus, the watchdog is unable to call nvidia-smi and I have to manually reset my rig.

When I run dmesg, I got a lot of those lines:

Any idea what causes this issue? The rig doesn't mine.

Is there a way how I can detect a faulty GPU/Riser, without removing the GPUs one by one? I thought maybe the GPU utilization log could do it, but I don't know if the GPU numbering there is the same like the numbering of slots of my motherboard?

Hi,

I have one question: Is there a way to add a watchdog listening to dmesg output? Sometimes, one of my GPUs crashes, and I see errors when I run dmesg.

Or is there any other way to auto reboot a rig, when problems occur?

Jesus christ the problems never stop!!

Now I am getting this error when trying to install AMD APP SDK 3.0  - "This installation package cannot be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify this is a valid Windows installer package"

This was installing fine until today.  I can't use claymore without it I don't think so now I can't mine at all.

Have you read my reply on your post a few pages back?

Well I have unplugged the power connector then plugged it back in, I don't know how else I can check it. What I can't understand is how can the risers be malfunctioning all of a sudden after days of mining?  The miner doesn't move, the GPU's are secure.  How can they work for days, then fail, then after a few restarts begin working again.  There is no logic there unless I am missing something.

Hi rawbot,

I have the same issue with my Sapphire RX 470 Nitro+ cards. Sometimes they run several days without issues and then one card starts failing and rebooting doesn't help. The only solution for me is then, to power off the miner, remove the power card and wait 30 minutes. If I power on the miner again, everything is fine. It is not a temperature issue, I have checked everything.

My guess is, that something gets weird in the GPU and only a longer power off phase resets this weird state. ^^

My 580 uses roughly 5W less power at the same settings than my XFX 480.

Have you locked to voltage to the same level, or how you have measured the power consumption?
11  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v8.1 (Windows/Linux) on: April 05, 2017, 03:53:04 PM


No, but you can use env vars, Readme:

...
You can also use environment variables in "epools.txt" and "config.txt" files. For example, define "WORKER" environment variable and use it as "%WORKER%" in config.txt or in epools.txt.
...

Thanks for the reply.

Do you know if this also works with the Linux version? I have tried $WORKER and %WORKER%.

Hi claymore,

is there an option to use the hostname as worker name?

Thanks.
