OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[FiatKiller]

Hello,

I'm using cgminer 3.1.0 to mine bitocins and minerd 2.2.3 to mine litecoins. I have o good problem. Minerd strangle cgminer. All the power of cpu or gpu go to the first.. At the begining this was verified at my laptop and then (after changing litecoin pool becouse I found another one better than the first) at the desktop too. Can anyone help me to use the two programs indipendently from each eather?

Thanks

You can do this, but only with "extra" CPU cores. Never do this with a single-core CPU. I have a six-core on my main rig and use 3 cores for feathercoin CPU mining no problem. The evidence of this is that I am getting 750Khs litecoin mining with both GPUs. Oh, and if you open task manager > Processes > rightclick minerd and set Priority to "Low". Helps to give cgminer first shot & decrease wear on CPU.

For the last day I get maaaany "rejected... <unknown-work>" errors. Hashrate down to bottom. What's going on??

same here

Upgrade your miner.

my miner is cgminer 3.1.0

Which has this known bug... upgrade to 3.0.1 or BFGMiner.

any solution without downgrading or move to BFGminer?

Use stratum directly if you want to mine there. That pool will redirect you to GBT which is a bullshit mining protocol anyway.

Cgminer says :
Connected to mining.eligius.st diff 1 with stratum as user XXXX
and i got the error

Then I have no idea and that's the first time this bug has been reported, and no other pool has such an issue. Since the vast majority of miners use cgminer on most pools, I'd have had a report. Perhaps since the original owner of the pool wrote competing software, he could go to great lengths to find a way to make sure you use it. Knowing our history I wouldn't put it past him. Maybe when time permits I'll investigate but in the meantime you're free to do what you like, be that mine on another pool or use different software. If you desperately want to use cgminer and that pool in combination, you can probably revert to getwork protocol with --fix-protocol.

Kano,
 i know this is the official support thread, and if you need me to move my post here i'll certainly do so. But by any chance can you please take a look @ https://bitcointalk.org/index.php?topic=114974.0 - i thought it's more relevant to my problem. Appreciate.

Can be -fix-Protocol be an Option ?

It is an option.
It means don't change the protocol if the pool offers a different one.
If you don't use it, cgminer may change protocols to something different if it is give the option.
However, if Eligius doesn't have the option to connect directly to stratum, then yes the pool has got it wrong.
You should be able to connect directly to the stratum server and with --fix-protocol that should not change ... like how all the other Stratum pools work.

I have a problem with cgminer. I get only 350 on a 7870GHz editon at 1250 core... But with GUIminer I get 453... I think it is a problem with me changing SDK and drivers finding the right combination and don't knowing how to remove openCL from cgminer.

I have deleted file phatk121016Pitcairnv1w256l4.bin from cgminer folder but this doesn't help... What am I doing wrong?

EDIT: And from the file I would say it is using "flegs" -v -w256 -I4" Can I change them to -w128 since I get better results in GUI with them.

had a question with Linux I get this error

im trying to mine on a hd6850

its on lubuntu but only have a 512mb ddr2 stick I was wondering if It needs more ram ??
is that why im getting this error

[abbeytim]

added another 512mb of ram didn't fix it so I set threadconcurrency to 1200 and lol it mines now funy cause I could do 6144 on my windows system

Figure it out... I had to add -k poclbm and it works even better then it was...  Looks like I found a better SDK and driver combination(as one that I had before reinstall) in the last cat 13.4... But that means that cgminer in auto mode didn't used best kernel... Not sure why

Weird. I thought all 7xxx cards defaulted to -k poclbm -w 64 -v 1. Try those settings.

Hard to say but I think it is about the same or a bit less...

It's all the the README
"platform" "gpu map"
(and if you are trying to mine on nVidia also you are wasting your time)
Sorry I can't read the README for you and transfer it to your brain.
And I wont read it for you either.

If you look closely when you read the README it also tells you how to make money (seriously)

Thank you for referring me back to the README. I'm not sure why I didn't understand it before but I think the card may be bad :-( cgminer just crashes now when I try to run it for the AMD platform. GUIMiner also tells me "Verification failed, check hardware! (1:0:Cypress, cabfe75b)"

Thanks again!

Quick simple questions, had a search but couln't find the answer.

I've got 2 discrete GPUs and onboard graphics. When I mine I run the 2 discretes and use the onboard for desktop management.

So, once I start up CGminer I immediately press "G" gpu management, then "D" disable thread, then I choose "2" for the onboard graphics.

How can I write this into a script to use in my startup .BAT file so I don't have to manually do it each time?

it's in the README, use the "--disable-gpu 2" switch or use "--device 0,1" to enable the devices you do want.

From the README:
--device|-d <arg>   Select device to use, (Use repeat -d for multiple devices, default: all)
--disable-gpu|-G    Disable GPU mining even if suitable devices exist

Thanks. I had read that but I didn't understand the |-G part after the command.

Not quite, but at least he tried to help. You want:

-d 0,1 --remove-disabled
