Hi Alex, Thanks for reporting this issue. Is this operation supported for this GPU? Have you checked with Vendor? Also do not use Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3” in xorg.conf.
Hello,
yes this operation is supported for my GPU, as it works on Windows using the vendor’s software (Palit Thunder Master).
I initially tried it without Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3” in xorg.conf already. I only put this there while troubleshooting.
Hi flair666, Are you running any application that drawing power more than 85W each. Can you share that app or tell me the app we can run that will help to reproduce this issue.
Hi flair666,
Below is the update from our QA team. Looks like issue is specific to GPU you are using or system you are using. From which Vendor you bought this GPU? Did you test same gpu in any other system?
Attempted try using dual GTX 1060 with default available BIOS, ran unigine heaven and 10 glxgear → could not observe the issue
Flashed vBIOS as per customer to 86.06.13.00.11 and 86.06.39.00.18, Ran unigine heaven and 10 glxgear → Could not observe the issue
Also updated the Game Deus Ex Mankind and played with the Dual GTX 1060 on power limit of 85W, Still i could not observe the power limit crossing over.
Downloaded the below app Tested with the config :- ( Dell precission tower 7910 + 2x GTX1060 + Driver 367.55 + Ubuntu 16.04 + Same vBIOS as per customer + connected to Samsung Sync master via DVI cable to single GPU )
Untar Claymore’s Dual Ethereum+Decred_Siacoin_Lbry_Pascal AMD+NVIDIA GPU Miner v9.5 - LINUX.tar.gz
Uncommented -epool, -ewal and -epsw from config.txt
Run ./start.bash
In Nvidia-smi i could not see much power utilization is happening
Power Utilization:- ( 2xGTX1060 with by default vBIOS 86.06.40.00.00 and with customer matching vBIOS the power usage are less compare to below details )
On Running Customer app :- 6W / 85W sometime for some moment it could be 25W / 85W
On Running Deux Mankind game:- 56W / 85W
On Running Furmark :- 82W / 85W sometime for some moment it could be 91W / 85W
Difference is only the system motherboard, whereas customer is using as per below config and same we are searching …
which is ok ,only that my Mate-desktop show only black screen with empty white panels.
Web if full of problems with multiscreen but none of multiGPU and one screen.
In basic your problem is that you shutdown xorg, nvidia-settings are dependned on it. For some unknown (for me) reason, nvidia-smi is somehow dependent on nvidia-settings in xorg and you shut it down.
Same problem i had when runing xorg, using option:
nvidia-xconfig -a, --enable-all-gpus
I got 150W/130W.
It has something to do with monitors attached to GPU. If one or more GPU would not have monitor you will have same problem. (or it is only me)
i think that it is a bug but…
P.S.
Also do not understand why is overclocking can be done only by powermizer in nvidia-settings. I have gone from windows to linux ,and still i am dependend on xwindows in linux.
And it’s not a vendor-specific problem! Just tried swapping several cards in my test install and it’s always the first card listed in nvidia-smi (lowest pci id?) that is affected by this. Also note that the issue is not simply incorrect power draw reported but the card is really taking more power (measuring at the wall).
I’m on 375.66 … and please don’t ask me to try with newer drivers I think I’ve done enough investigating work for you already.
I was able to work around this issue by ensuring that the integrated Intel GPU is the first GPU in the system as shown with lspci -k | grep -A 2 -E “(VGA|3D)”. Some motherboards won’t enumerate the iGPU if there is no monitor connected, so I will use HDMI dummy plugs.
