Ubuntu 16.04 - build of latest code #213
Comments
I'm guessing your hardware is hanging, downclocking it might help. |
|
Thank you for the response! I will try to use the binaries in the release section today and tell you if it behaves better. The weird thing was that after that 94% I wasn't getting any other notifications event waiting for 2-3 minutes. How often should I see log statements normally? |
|
I tried with 0.11, I downloaded from the binaries part. These are the logs I am getting: m 00:22:30|ethminer Mining on PoWhash #a0f32346 : 0.00MH/s [A0+0:R0+0:F0] After that the system hangs and I have to perform a restart. Also I checked the power meter I have and it stacks at 180W normally with other miners I am at around 350W when using both cards. Also these are the dpm settings: manual Thank you for your help. |
|
Today I tested 0.11 with a monitor attached in the card and I finally got some exceptions. I am attaching the pictures I took. I have tried lunching each card individually and in both cases I got the same exception.
|
|
any chance you didnt undervolt your cards yet ? |
|
What do you mean undervolt my cards? I get these errors after a cold boot without touching any settings. I have forgot to mention that I am running the default ethminer and claymore with no problem . |
|
edit : just saw you have no problemwith other versions of ethminer. AMD cards are Power hungry,
|
|
I have an Enermax 850W Platimax 80+ Platinum PSU and with other miners I can see in the watt meter that they reach 370-380W without any problems, I only have 2 graphic cards in the rig. The cards now running with the ethminer I downloaded with apt-get run at ~60C with the pwm set to 150. The highest temperature I have seen them is running at 76C. Do you know if in linux I can undervolt or limit the cards in any way? I have only seen the configuration through the drm. I may give a try also running the rig with windows. |
|
Personally I can't help here a lot, but have you tried running only single GPU? |
|
@antonismandilas I gave up on linux with my RX470s. Even with undervolted modded BIOS linux would kick them back to full power. On windows WattTool makes it simple to undervolt, and I got my cards WAY down on power. So, for now I gave up and use Windows. As a benchmark my rigs are 7x RX470 with total wall wattage of ~760w, achieving low 160s MH/s on ethereum. I run a GPU clock of 1075 and a memory clock of 1975 both limited to 810mv. The cards are flashed with the 1650 strap. That said, I did come across this script at some point, but couldn't get it to work. I didn't try too hard though. https://raw.githubusercontent.com/rumatoest/dwarfing/master/amdgpu-mod.sh If you figure it out, PLEASE let me know. I would much rather be running my rigs on linux! :) |
|
I tried with windows and I still cannot run the ethminer, the system hangs as soon as I start the miner. I will try the under-voltage setting today. I saw that the default value in WattTool is 1000mV. Since yesterday I am testing the system with claymore miner, which gives me 42MH/s solid. I gave a small boost in the memories and lowered the GPU clock. The GPUs run at 55-60C, in the wall the consumption is rated at ~290W and the system is stable. |
|
@antonismandilas did you make sure that you manually set virtual memory on windows? I set the min to 1043MB and max to 16400MB. Otherwise, it'll hang. Yes, I believe 1000mV is default on the card bios. |
|
@michael-pesce I set the virtual memory today. Doing some tests I managed to make the miner work when I removed the work parameters. My settings were: --cl-global-work 32768 --cl-local-work 64 If I remove both it works fine, leaving any of them with any value makes the miner either to break or the system to hang. Currently I have the miner working and I am trying different configurations for the GPU & memory clocks. My current settings are: The mining speed is between 30-40 MH/s |
|
After running for some time the miner, the only thing that I noticed is that I am not getting any reported hash rate in nanopool, the reported hash rate value is always zero, although I am getting shares. The command I am using to launch the miner is: ethminer -G -S eth-eu1.nanopool.org:9999 -O address/email --farm-recheck 1000 |
|
try using when i run it like that the hashrate shows up on pool also . |
|
@michael-pesce https://github.com/OhGodACompany/OhGodATool works for underclocking core and overclocking ram. they have a paid tool for undervolting that costs 1.5 BTC but, i'm using 17% less juice, and lower temps+fans with same hashrate just by lowering core clock and raising mem clock. |
|
@ITwrx Thanks, hadn't seen that. I am not sure I am ready to spend 1.5 BTC to move to linux, as I have this working on Windows. Maybe if I had a larger farm... |
|
@antonismandilas The You should try upgrading your kernel, or just directly report the issue (with a detailed dmesg + hardware you are using + the program you are running) at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI If your card does lock up the system on both operating systems (Linux and Windows) though, you are running very likely into hardware issues. I personally have no issues with my Tonga (same as your first one) on both Windows (using current Catalyst) and Linux (using the mesa drivers). |
|
another note for anyone reading this thread. Take it back to basics, try getting one card at a time to work. |
|
@antonismandilas It's all running now? |
|
@DeadManWalkingTO I abandoned Linux in favor of Windows 10. Everything works great and the latest version is super! |
Dear all,
This is my first ever message in this list so excuse me for any mistakes :-)
Yesterday I tried to build the latest code, I downloaded the latest code, build it with no errors, but executing the final executable ended up hanging my PC and needed a hard reboot.
My setup is the following:
Ubuntu 16.04 server headless
1x 380 4GB
1x 470 4GB
latest amdgpu-pro driver 17.30
Both times I tried to run the produced ethminer:
After that point I am not able to kill the process neither do a normal reboot.
I can only hard reboot it using the the power button.
What am I missing??
Thanks in advance,
Antonis
