About GPU slot corelation in motherboard and numbers in claymore.
In my most of cases (accually all of them) i have this corelation:
But still i cant tell if this will apply to all motherboards or is it just a "luck"

If you want debug bad gpu, best it would be to:
- set minimum fan speed to something like 70%
- insert option in claymore -wd 0 -r 0 (unfortunatley right now it will apply to all rigs and cause to reload all of them) (in future there will be grouping managment so it wont be an issue), also i think i will make something like "make GPU3 spin at 100% for 1 minute" - then it would be much easier to debug it
So the options wd and r set to 0 will cause that the claymore miner wont reboot GPU if it will hang.
Next you could wait until gpu will coll down and then just touch backpate of each gpu and see which one is coolest





Well, there are people who says that 2$ per rig per month is total rip off for "free ubuntu"...
But ok everyone has a choice and own opinion. Anyway this is like 1% of whole users so i guess it is accepted level of not happy people.
There always be some angry and agresive people who mostly thing that this should be opensource and free and yet still they would say bad things about it
When it was free, there also were some single bad optionions
But as i said, i am not greedy and i know that many features are missing right now and i am accually out of deadline for the "rig grouping feature".
Still i decided to take 2$ per rig per month becasue i was only way to speed this OS developemnt.
Just for you guys to know - i feel bad about this missing "rig grouping feature" becasue i said many times that it will be "soon" and it isnt.
I know about this and i feel bad about it just for you to know.
Anyway lets wait about 15 working days more and then the new dashboard should be ready and then we will skyrocket in out new features
Lets wait until rewriting of website will be completed, then new features will be implemented very fast
I will make some list of features and propably there will be some voting which is most important for you guys.
My list is long but i want to implement all of them including statistics, notifications, and then some more help and tips which will appear here and there.
Also i am holding off with official chat becasue it will be propably implemented directly in dashboard so i dont want to mess and give other chat now and then in 20-30 days change it to something else

I got the same problem. I use explorer

Well I initially followed another user's settings (the same one Tytanick keeps posting) for 6 gpus which was basically just update bios, enable 4g, and use integrated graphics.   That works... in general.   My problem doesn't seem to be an issue with booting 6 cards, but one specific card.   I really think that the problem was that I have a bad card.  Whenever that card is plugged in is when I get the errors, and not just when I plug it in as the 6th card.   If I use this card with 2 others, I get those ring errors.   If I don't use it, I can use 5 cards with no errors.    I mean, I can play with some other settings, just saying what I have tested.  

Thnk u for the answer. I know how to get percentage of gpu fans. The question was - what could be wrong with exactly hwmon3. It shows pwm1 of 73 with is about 28% of max fan value, while at the same time fan1_input have crazy value of 3306 rpm. I dont want to regulate. My goal is to get current fan values in rpm, not percentage.

Thanks SealTx.  That'll help me track down GPUs.  Unfortunately I noticed the fan still runs after mining is disabled, but it does slow down so hopefully I can pick out the GPU when needed.



Thanks tytanick.  I assumed that would be the case/numbering scheme, but you know what they say when you assume.

That is great power usage.

I am wondering why we cannot change the power limit in a similar way we do on the nvidia rigs as on the amd rigs? I also am drawing 950-1000 watts for  6 x 570 4gb rigs and would love to bring that power consumption down so I can add more rigs in my basement XD

Just wanted to offer a counter point to all the whining. I'm running 6 rigs, 470s, 480s, 570s, 580s, Nvidia 970s (2), Nvidia 1070s (4?). All working great, mostly Z170 MSI boards but the 4 card rigs are on some old ass i7-930 (1366 socket) and i5-2500 (1155 socket) boards, also working great! I set the 1070s/970s to 100W and they are very stable and low power usage but leaving 5-6MH/s on the table without overclocking.

Tytanik! You are the man! Keep up the good work and thanks for offering an easy web interface, no driver installs, problem just reflash the USB! All for $2/month? This is an insane deal!

Can't wait for NVIDIA Overclocking feature. The 6 1070/970 mix are using 640w at the WALL! Im using Claymore 8.1, but 9.4 also works great. 9.5 crashes non stop!

Is there an attachment button where I can attach the screen shot or do I have to host it somewhere and link it in?


PS I also have a MSI 7 slot with 2 M.2s I'm going to try to get 9 GTX 1070s running on soon I will post results! Sorry first time using this particular forum site.

Last Bios didn't work well use previus bios so boot with 3 cards 4G decoding disable after boot os and mining shutdown and enable 4G decoding save and turn off put the others gpu boot normaly note pci latecy timer must be set at 96 and disable all unnecesary features and ports like Windows features audio and serial ports .

The only reason why I ask about the GPU is because this motherboard has been tested for 9 gpus it is the Asus Prime Z270-A and I had it working on another linux distro, but really liked what you were doing here so I decided to switch. Any other possible issues you can think of?

Meaby your motherboard doesnt support 7 gpus ?
If motherboard has 7 slots it doenst mean it will support 7 gpus

In most cases (in my envoroment) it is like that: But in other enviroments i cant tell if this will also be like that !

This is Linux OS. And linux Operating system is totally different from windows.
Basically it is much more stable and much more "out of box" than windows but we dont have undervolting tools.
There are some private tools (which i dont have) but i guess people wont release those.
As now only solution is to make custom bios with added offset voltage.
Then it is working, my rigs with 6x470 are taking about 750-850 watts from wall depending on oc settings.
I know a guy which is adding voltage offset to bioses, if you want contact him let me know by email: [email protected]
But i guess the prices are from 0.1-0.2 btc per one gpu model bios.
Here you will get a list of fan speed devices in linux:

root@simpleminer:~/utils# ls -1 /sys/class/drm/card*/device/hwmon/hwmon*/pwm1
/sys/class/drm/card1/device/hwmon/hwmon0/pwm1
/sys/class/drm/card2/device/hwmon/hwmon1/pwm1
/sys/class/drm/card3/device/hwmon/hwmon2/pwm1
/sys/class/drm/card4/device/hwmon/hwmon3/pwm1
/sys/class/drm/card5/device/hwmon/hwmon4/pwm1
/sys/class/drm/card6/device/hwmon/hwmon5/pwm1
root@simpleminer:~/utils# cat /sys/class/drm/card1/device/hwmon/hwmon0/pwm1
153

If you want to convert this value to % then you need to make simple calculation 153/254 which is 0.6
Multiply that by 100 and you have 60% fan speed.
So the max speed for gpus is 254 and you can inset that speed to the system by using command:
as root: echo "254" > /sys/class/drm/card1/device/hwmon/hwmon0/pwm1
But renember that my script will overwrite fan speed in system.
(acculaty it could be 254, 255 or 256, i dont renember what was top value

guys does -dcri setting not work in claymore 9.5, it seems to always be 10%...

Not a SMOS question, but linux related. I am getting 4 values for gpu fans (4 gpu rig) in dashboard: 33,28,28,40. Made some basic bash script to send fan values to my monitoring box. In is based on /sys/class/hwmon/hwmon?/fan1_input values. The issue is that one of gpu shows some crazy shit in /sys:


while dashboard/claymore show less then 50% for each GPU unit... lmsensors package shows the same. It is using /sys/class kernel subsystem.

GPUs are Sapphire RX 470 Nitro+ with modded bios.

Is there any way to get correct rpm values in shell?

hello lads. searched through the thread, but couldn't find an answer. i started using smOS recently and rigs are just doing fine. the only thing i do not like is the consumtpion. f.e. on RX 470 rigs.

6x RX 470 with custom BIOS were using in Win 10 with core 1150/memory 1950 like 860 watts from the wall

with smOS and same settings and PowerStage 1 the rig uses like 960-980 watt from the wall. I started with Powerstage 4 and went to 1 but the consumption didn't change a bit. Yes, i restarted the rig each time.
any ideas how one could further improve the consumption?

thx in advance

My mechanic is a badass. He opens shop at 4am. If I have my truck to him at that time, its ready to pickup by noon. My truck has all kinds of mods and runs great all the time... because of him. A couple of times he has made a mistake or missed something that made it so I had to drive my wife's Honda. Guess what? He made it right.

He reminds me of Tytanick. That is what I am communicating here. I love people like that.

When the miner is running, you can press a number (0 - 9) to turn a card off or on. I just watch the fans, and start with 0, then 1, etc...

Is there a way to tell which GPU is in which slot?  For instance, lets say I have a 5 card rig and GPU 3 is having issues.  If I want to physically pull GPU 3 and try it in another rig, how do I know which card is GPU 3?

Hey thanks for this amazing piece of software. I have just one issue I made all the changes you suggest in the bios however only 6 of my 7 gpus are showing up, any advice?

+1

Thanks for your progress update earlier too. Glad to hear you have tracked down help with your project. Good things grow organically rather than having to be a scheming 'better pro' watching 'market conditions' and listening to valuable paying customers 'rightfully complaining'. Looking forward to tracking how nvidia support progresses.

Thx for your opinion.

unfortunately I can't try it because the ps4 pro isn't jailbroken till this date so you can't boot anything except ofw as you can't get root access...but if anyone has an idea how to do this I would gladly try
