Optiminer/Zcash v1.7 (GPU, Windows+Linux, AMD)

what bat file with watchdog and autorestart miner on WINDOWS?

[jumphost404]

I have switched to Linux ( ubuntu 16.04.1) but have been experiencing my screen not being recognized between switching rigs ( plug in hdmi in one rig and plugging back into same gpu I started with on another rig ) also on startup I have seen my screen not be recognized.
Here's what I did:
install ubuntu
Reboot
Sudo apt update
Sudo apt dist-upgrade
Reboot
Sudo install new amd 16.50
Reboot
Run miner, see gains  
Move to next rig repeat
Came back to the first rig and screen isn't recognized.
Missing anything?

I know i'm not answering exactly what you expect, but how does that matter ?
Can't you use ssh to admin your rigs ?
Or the issue isn't about administration but rather about the miner not working because the screen is not recognized ?
=> My setup is 100% headless, no fake hdmi or anything and it works like a charm.

Agreed - headless is the way to go. There's an issue with the way xorg works in the new versions of Ubuntu. I have found that installing 3 packages makes it work well.

This is what I do:
install xorg xserver-xorg-legacy xserver-xorg-video-dummy

Edit the config file for xorg-legacy:
/etc/X11/Xwrapper.config

delete the last line:
allowed_users=console

insert at end of file:
allowed_users=anybody
needs_root_rights=yes

then set up the xserver-xorg-video-dummy

There's a bit more to getting the headless fully working in a screen, but this gives you a start. I don't want to keep flogging my build guide, you can probably find a link in a previous post if you want. It took me a while to figure it out, but once you get full headless going it's wonderful.

I tend to get slightly less performance out of the GPU that my monitor is hooked to, although it is a XFX R9 380x vs the rest of the cards in the system are just ASUS R9 380 Strix.  If I were to switch it to headless would I gain a little extra performance off of that GPU?    I'm not positive the less performance is due to the monitor being hooked to it or if the 380x has less performance but I would think if anything it should be more than the 380.

I agree headless would be the best option, and I will get there. Along with getting miner to start on startup... Miner ran for 4 hours and crashed on 2 rigs overnight    But performance for my 480s is at 300 s/S. So it looks like Linux is the best option for now, and figure in stability.

I'm also making sure I haven't missed anything, like increasing my page file to at least 16 gb like I would do on Windows.   or use redhat?

^^ The 16 GB virtual memory setting only applies to Windows. Linux does not need any such setting.

Help guys!!!, what bat file with watchdog and autorestart miner on WINDOWS?

[nevermind41]

How can you setup the voltage, gpu and mem of the vga in linux? Any software like wattool?

[deadsix]

I run my cards undervolted and underclocked, so my RX 470's running at 1100/1750 get about 230 on Claymore's 11.1
On Optiminer, the same settings are getting me about 210, so about 10% lower at the same power draw, but Optiminer has historically been better on Linux.

1.6 looks pretty good.  Getting 345sols from a 290x clocked at 985/1375.

It depends on what GPU you have and which driver you're using, so you haven't provided enough info. If you are running RX GPUs, the answer is no, because the amdgpu-pro driver does not currently allow voltage/clock control. At some point down the road, AMD is supposedly going to release Wattman for linux. For non-RX GPUs using the older fglrx driver, you can adjust core/mem clocks, but not voltage, although exactly what you can do depends on the GPU. Fury series GPUs, for instance, cannot overclock memory on the stock bios.

Sorry, I forgot to write the cards type that I use. I have RX 470 series cards. If the only way is using linux to get the best speed, optiminer isn't profitable for many users who use expensive electricity.

I am getting this error with 1.6:

OpenCL error: CreateProgram base (CL_INVALID_BINARY)

1.5 worked fine. Any Ideas?

Try with -c 1

adding -c 1 had no effect.  disabling on board graphics adapter resolved the issue.
thanks for your help

RX 470 (MSI and sapphire) get 262-272 on Ubuntu 16.04 without undervolting and underclocking on default settings.
Is it really beneficial to underclock/undervolt?
somehow 1.6 is less stable for me (so far) than 1.5 and 1.5 was less stable than prior.

You can always flash custom voltage/clock values on your GPU bios, under Windows, then run it on linux. I undervolt my Nanos using a vbios rom I made on Windows, and it works perfectly. There's no need to alter any card settings in software after that.

I can use multi os for mining, this is acceptable but I can't use different vga bioses for each coin. This isn't useful type.

Good work Mr. Optiminer    ด็้็้็้็้็้༼◉Д◉༽ด็้็้็้็้็้   So far about 385-400 sols for a 390, 220-230 for a 380 and up to 300 for a 280x all under windows, so cant complain.  It seems Claymore is playing catchup, but there is a lot of suspense - his next version is coming out quite soon.  oh the excitement lol

Hmm I havent set that up to be honest, i never needed to.  Anyways try running your bat file with -help or --help or -h whatever and you'll see the details of the commands.  Or go http://www.cryptominingtalk.com/bat-files/ and see the examples, like do

title Rig6
:start
genoil.exe -c zec-us.coinmine.pl:7007 -u fr4nkthetank.6 -p x -P 0 -f 2 -i 20 -w 64 -k zec zec
cls
timeout /T 10
goto start

that should work I suppose, havent tried it since genoil Zec.  anyone remember that lol

[oldisoft]

Is it virus? or like usually like with claimore ?

is it useful in any pools?

Cheers

[batut]

how to write the command watchdog?

SET GPU_FORCE_64BIT_PTR=1
optiminer -s %POOL% -u %USER% -p %PASSWORD% -m 8080
pause

[vectisitch]

HELP please,

 i am using 1.6.0 on my rig with 2 cards with this .bat  GPU_FORCE_64BIT_PTR=1
optiminer  -s zec-eu.coinmine.pl:7007 -u xxx -p xxx

 it's running fine.
with the same .bat file on my 4 card rig i get "GPU_FORCE_64BIT_PTR=1 unrecognised string blah blah you need to set variable GPU_FORCE_64BIT_PTR=1"   any ideas please.

Yup.  You have to put set GPU_FORCE...etc
Set command sets it as environment variable for the command window session,
setx command sets it for the whole computer on a permanent basis.  i recommend just set.
