Why does GPU0 have much less performance than others?
I tried from 2 to 6 cards 470 and 580
On the cards nVidia there is no such thing, everyone works the same performance.

Is your monitor plugged into GPU0?

Have you modded your bios of GPU0 the same as the other cards?

Can you try another MoBo?

I am running 40 cards total on this version and modded all cards with timings, undervolt and clock speeds and I don't have that issue at all.

All my AMD rigs GPU0 performs the same as other GPU's that are alike.

I found the problem. Changed BIOS settings from "GEN1" to "AUTO"

@Fullzero

Version 0013

Can you make a global switch to turn off all overclocking?

OVERCLOCK="OFF"

This will allow a single onebash to work on rigs that have all cards fully modded and have mixed R9 with RX.

Currently I just did this.... Get some errors but it works...

# select level: to see supported clocks scroll to the top of the mining process
#  __CORE_OVERCLOCK_LEVEL=7  # for ETH use lowest without decreasing the hashrate / Highest for ZEC
#  MEMORY_OVERCLOCK_LEVEL=1   # use highest level

Unless I am missing something if the cards are modded with timings, undervolted and clock speeds then rocm-smi is unnecessary. (right???) (except maybe for fans)

Just an idea for more flexibility....

I will make a switch like this:

You probably want manual fans; so I will exclude that.

So I have been watching all the cool stuff going into the Nvidia build and wondering why the AMD build is getting no love when it occurred to me....Why not make ONE build for both?
Wouldn't it work to just have AMD AND Nvidia drivers in one build?

I am currently building a new mixed rig with 4 AMD and 1 Nvidia and plan on using rxOC build 12 and adding the NV drivers manually and then just run a second screen.
Thats sort of where this idea of a single build came into play..

Some sort of switch like IF GPU=NVIDIA THEN (DO SOMETHING HERE LIKE USE NVIDIA DRIVERS) ELSE (USE AMD STUFF HERE)

Just thinking out loud...

[osnwt]

fullzero wrote that there are some issues with X11 configuration mixing the drivers. I guess it is ok in manual mode for particular installation/rig, but a bit harder to make it for any configuration of rig.

[OverEasy]

Yeah I guess there must a good reason why Fullzero hasn't already done it lol..

I am changing my idea some right now. Burning the NV version and then adding the AMD drivers. That way I get all the new features

Back to Windows for mixed rigs...

[QuintLeo]

Mixing AMD and NVidia in LINUX is at best a royal PITA, and often just flat out doesn't work.

 I spent about 3 WEEKS trying different things to get the AMD 15.12 drivers and a reasonably current NVidia driver working on one of my A10-7860K based rigs, never did get it all working so finally gave up on the idea.

 That's WHY I'm currently working on shifting cards around as I can, to get them away from mixed-GPU so I can drop Windows in favor of much-more-reliable LINUX for my dedicated mining rigs - it USED to work, but doesn't seem to do so any more on recent driver versions.

I will implement all the transferable changes from nvOC to rxOC.  Some of them are Nvidia api dependent and might not have an AMD version and thus are not transferable.

Newer versions of *nix don't like mixing nvidia and amd.  I have gotten them to work together on specific rigs and in console mode (they don't like X together); but the methods I used are in no way portable.  Also only Claymore Ethash client seems to support AMD and Nvidia on the same rig; so there is little incentive to merge them.  This is as QuintLeo has said before; something Windows does better.

Need help guys. My rig keeps crashing and I don't know why. Running rxoc v0012

mobo is biostar tb250-btc
gpu 1 is a sapphire 580 4gb nitro+
gpu 2 is a xfx 480 4gb (with the stupid white leds)

If I run both gpus with unchanged clocks on onebash, I get pcie bus errors and it fills up the USB. I know it's not the risers because I tested them individually (after receiving replacements from the seller) on both gpus using smOS and rxoc individually and got no pcie errors.

I'm mining ZEC and it doesn't matter if I use optiminer or claymore, eventually the system hangs due to some error. I checked the error logs and this is a snippet of what I find

What's going on? bad gpus? bad mobo? risers have been swapped out already 2 times. I am a total Linux noob by the way.

First I would try setting:

Code:

OVERDRIVE="NO" 

and seeing if that is what is causing the problem.

Ensure your fan speed is set high enough to keep your GPUs cool:

I would try 200

Code:

FAN_SPEED=200

It also looks like there are some disk errors occurring: if disabling the overdrive and increasing the fan speed doesn't solve the problem: I would reimage the USB or use another USB.

Let me know how it goes.

fullzero, thank you for your NvOc and RxOc. Can you please update the RxOc? I want to change SimpleMining to something better, flexible configuration, but RxOc is didn't updated so long time and I don't know if you stop working on this.

I am planning on updating rxOC with a new version this week.  First I am updating the 1bash for nvOC with all the requested coin changes / then I will update and release a new rxOC version.   

Doing it this way is faster in the long run.

[Zucca]

Maybe this will work:

Ensure the monitor is connected to the primary GPU ( the one in the 16x slot closest to the CPU )

Disconnect the USB or SSD/HHD from the rig.

Fully power off everything: including the PSU.

Press the power button several times to clear any remaining power in the mobo.

Turn the PSU powerswitch back to | "on".

power on (without the USB attached)

See if the bios posts; if you get nothing in 20 seconds; press ctrl + alt + del repeatedly until the system reboots.

Wait and see if the bios posts.

If the bios posts attach the USB key to a USB 2.0 port and press ctrl + alt + delete.


if it boots; stop the mining process before it starts mining:

then go to the top left and click the ubuntu button

type u

and click on software updater

run updates

reboot

Let me know if this works.

I tried with a new motherboard MSI Z270 Gaming Plus with only one GPU directly connected to it,  and a new PSU.
Same Result.
I have extra pendrives but I am not able to copy the image there because they are 15.5 Gb and I it needs 15.6.

If the bios posts; you can access the grub loader menu by pressing

esc

continuously while booting (note holding it down doesn't usually work), then select boot in recovery mode. 

in recovery mode:

Enable networking

then install updates from the cmd prompt:

Code:

sudo apt-get update && sudo apt-get dist-upgrade --yes

and reboot

this should ensure your build has all known system files for your system.

I tried again a MSI Z270 gamining PLUS, only one gpu connected to the monitor, disabled avobe 4g memory, and it worked.
If I enable 4g, the screen gets like this http://imgur.com/a/w8sSc . Dont even reach grub.
I tried in UEFI and Legacy, and PCI gen 1 and 2.

and pci errors in syslog.log but I know for a fact that the risers are good. I think it might be the mobo, Guntis Vintolins posted a video on youtube and had problems running your OS on biostar tb250 (he has the 12 riser board) and went back to his previous OS. What else do you suggest I try?

See if the bios posts; if you get nothing in 20 seconds; press ctrl + alt + del repeatedly until the system reboots.

Wait and see if the bios posts.

If the bios posts attach the USB key to a USB 2.0 port and press ctrl + alt + delete.


if it boots; stop the mining process before it starts mining:

then go to the top left and click the ubuntu button

type u

and click on software updater

run updates

reboot

Let me know if this works.

I tried with a new motherboard MSI Z270 Gaming Plus with only one GPU directly connected to it,  and a new PSU.
Same Result.
I have extra pendrives but I am not able to copy the image there because they are 15.5 Gb and I it needs 15.6.

If the bios posts; you can access the grub loader menu by pressing

esc

continuously while booting (note holding it down doesn't usually work), then select boot in recovery mode. 

in recovery mode:

Enable networking

then install updates from the cmd prompt:

Code:

sudo apt-get update && sudo apt-get dist-upgrade --yes

and reboot

this should ensure your build has all known system files for your system.

I tried again a MSI Z270 gamining PLUS, only one gpu connected to the monitor, disabled avobe 4g memory, and it worked.
If I enable 4g, the screen gets like this http://imgur.com/a/w8sSc . Dont even reach grub.
I tried in UEFI and Legacy, and PCI gen 1 and 2.

Have you tried updating the bios on this motherboard?

Hey,

I tried to image rxOC on a 32 gb flash drive, I am using the link with multiple colors for v0012 -  "rxOC_v0012 Google Drive Link use this image for all mobos"

is this the correct link to we download and then image onto our usb after we decompress it?

I imaged the usb and tried using it on one of my rigs but it's just a black screen for hours with some text in the top left corner.
/devsda2: recovering Journal
/dev/sda2: clean, 456748/958464 files, 2246366/3805440 blocks

I tried doing the cmd and typing what you said to put and I get "they system cannot find the file specified"

I tried this on my mac as well and the command does not work, so what am I doing incorrectly? Thank you!
