Ubuntu Natty Narwhal 11.04 Mining Guide / HOWTO

[marcus_of_augustus]

Okay I finally got everything to work.

When I do ./poclmb.py -o btcguild.com -u (username_user) --pass=(password) -p 8332 -d 1, it gives me problem connecting with bitcoin error. It'll stay there for about a minute, then it'll start mining. But then 5 seconds after that, it'll say "verification failed, check hardware!"

Help!! So close!!

Okay in this thread you have originally asked questions relating to solo mining and then the command you put here is trying to connect to a pool.

Do you know which it is that you are trying to do, solo mining or pool mining?

If pool then you shouldn't be running bitcoin -server (it will conflict on 8332) and indeed, do not need to be running any instance of bitcoin whatsoever ....

Really? I didn't mention solo. Anyways, I'm trying to do pool right now, hence the -server.
I think I got it...the only problem is is that poclmb won't see my other 2 video cards.

And is there any way to write a batch file type thing to run poclbm on all 4 cards instead of having to type it out on terminal?

No, you didn't mention solo ... BUT the only reason you'd need the bitcoin -server locally for a mining set-up is if you were solo mining ....

[IlbiStarz]

Oh..didn't know. So pooled mining you don't have to start bitocin with -server?

Poclbm is working on my 2 5850's, but the 2 6870's are not showing up on poclbm when I enter start it without anything. How do I get the recognized?

[IlbiStarz]

Is there a way to rewrite the op instructions for sdk 2.4? I think that would solve my problem.
I tried doing it using AMD-APP...etc and renamed the two files in OpenCL, but then poclbm wouldn't even start, gave me an error.

I've been at this for about 4 hours.

THIS GUIDE NEEDS TO BE REWRITTEN!

For the 32 bit version, it's got all the wrong file path names and commands strewn throughout - for a Ubuntu newb like me I want to smash my screen.

Now I got it semi working, but when I run poclbm it only displays my CPU, not my graphics cards.

How do I get the gpus to show?

If you're running the 2.1 version of the SDK, then your GPUs may not be supported. I haven't actually set up a miner with 2.4 yet, but I know 2.3 supports all the current ATI GPUs up to the 6990s. To update your SDK, change all the references to 2.1 that you added to your .bashrc to 2.3, then remove the 2.1 SDK folder, replace it with the 2.3 SDK, and rebuild pyopencl.

If you really want a clean start, you can reinstall Ubuntu and then run these scripts I threw together.

Your computer will reboot after running prep_up.sh. If you don't like that, remove the "sudo reboot" command at the end of the file.

Can you be a little more specific?  What commands and pathnames are incorrect?

Why is anyone running the 32 bit version anyway?  Are you all really trying to run that old of a CPU that it doesn't have 64bit support?  That's cool if you are, but I didn't expect anyone to be sporting a decade old CPU with mining.

[IlbiStarz]

Is there a voltage command through terminal?

[MiningBuddy]

Is there a voltage command through terminal?

Aticonfig doesn't support voltage modification as far as I know.
I use AMDOverdriveCtrl instead.

[IlbiStarz]

Downloaded it through the software center...how do I start it o.o

[IlbiStarz]

Nvm got it.
It says you can only use powertune for 6xxx cards

[IlbiStarz]

Will 6870+6990 work if I use 2.4? And will they run on a 850w?

I keep having problems communicating with bitcoin RPC via poclbm (not sure how to use pheonix) can someone give me a hand on this? Also, what does the flag -f# does? Higher number gives higher priority? or what?

I agree that this guide has gotta be re-written. Theres too much errors on it, especially on the x86 parts.

Just one more thing, I've never really experienced with clocking stuff, so I need some brief explaination to

1. Underclocking Memory
2. Undervolting - ??

-f increases frames every second or something like that. Increase it if you want less desktop lag. People usually use -f 1 for pure mining rigs.

1. Well if you are in linux, there's no real solution right now except for changing the bios, and you have to use Windows for that. Guide : http://forum.bitcoin.org/index.php?topic=9569.0
2. Same thing with overvolting, I think..

Basically, any big under/overclocking has to go through a bios change for linux. Depending what card you have, there will be limits of how much core and memory can go. Asus is the best, can go up to 1000core i think. (5850's) However, underclocking/volting is harder because all the cards have a high lower bound.

You are wrong about 1). The memory can be underclocked in linux without modifying the bios. Read the forum threads titled the same.

Yes but not much. If you are going to underclock to the "sweet spot" to raise hashing, you have to modify bios. Lowering the memory just to the lower bound isn't going to do anything.

Wrong again. In linux you can lower the mem. clock of 5970 to 300 without altering the bios ... read the forum threads titled the same. (I do it all the time.)

[IlbiStarz]

Okay I didn't know about 5970s... But my 5850s are only lower-able to 700 or something.

So you are the second person to say the guide needs to be rewritten because there are "errors" but as of yet, no one has pointed out a single error.

Also, why are you using the 32 bit version of Ubuntu?  I'm not saying there aren't valid reasons to be using it, but I'm just curious if you have a 64 bit CPU, there is absolutely no reason to use the 32 bit version for mining.
