Bitcoin Forum

Hello everyone, I'm an Ubuntu user (relatively new but have done some things with it) and have just discovered bitcoin. I was following the instructions in this topic: https://bitcointalk.org/index.php?topic=50388.msg600306#msg600306 hoping to be able to mine for bitcoins at the end of it, (which is where my problem starts). The instructions are for an ati GPU but I'm running an Nvidia GTX470

When I start what I believe to be a python script, I get the following response

brian@precise:~/poclbm$ ./poclbm.py
Wrong platform or more than one OpenCL platforms found, use --platform to select one of the following

•    AMD Accelerated Parallel Processing

I need help fixing this. I don't know where to start looking. could someone point me in the right direction?

I would really like to start mining with my nvidia

P.S.
I have an ATi card sitting on my bedside table (it's a 4850 though) and will have a spare (dual-core) computer by the end of the week . The computer was meant to be an htpc - home theater PC - but it could serve as a miner as well.

Hmm... lots of brackets. I must be tired. Going to bed: will check on this in the morning.

Welcome to the Family!

I can't help you out with Ubuntu, but I have a quick way to get you up and mining. Download the latest BAMT build @ bamter.org. Load it up on a 2gb or higher USB drive, and get going. Its easier than Ubuntu and requires close to no experience with linux. I really would recommend it for a new guy like you.

Let me know if you need any more help. Feel free to pm me as well.

WOW! Awesome! Thanks a lot. :)

Oh! I'm supposed to edit the files before booting to the usb drive?
When booting I get an error: "No default or UI configuration directive found!"

EDIT: I'd also like to save up for a while to buy parts for one or two mining machines. Where can I learn more about this?

Do you have a gigabyte motherboard?

Yip! Is that a bad thing? ???

EDIT: It's a GA790FXTA or something. I think I bought it in 2010 just before the new MOBOs came out.

Would it be the reason why BAMT is not working?

Yup. I'm in the middle of a xubuntu tutorial for my rig and will send you some info once I load it on mine. Gigabyte mobos don't work with bamt

nckrazze, off the top of your head, do you know if ASRock motherboards, specifically the mb-970ex4 will work with BAMT?

Thanks,
davecoin

Yes, they should be fine.

Read what poclbm tells you.
Try ./poclbm --platform 1
And if that fails, try
./poclbm --platform=1

Hope this helps!

OH COOL! I look forward to it. Thanks  :)

SWEEET!! just added the .py to the end of "./poclbm"


Um, I'm guessing now that I just need to type:    ./poclbm.py --platform 0

Thanks so much

EDIT- Didn't work as planned.

do I perhaps type in: ./poclbm.py -d 0

Apparently not:

Oh wait what? It seems as though I'm setting things up.

So, I think I figured part of it out. (with the help of whiskers75)

I just don't know what to punch in now..
What server? I'm not sure.

Hey nckrazze, do you also have a Gigabyte MOBO?

Unfortunately.

This is the best tutorial I have found and it works. If you have another distro, no need to install xubuntu, just follow the rest of the steps. And I used this method on a hard drive.

Edit: https://github.com/kanoi/linux-usb-cgminer/blob/master/linux-usb-cgminer

cool! I'll do it now. wait  ??? do you have a link to it?

OH I see it now.

Before I go anywhere with this does the usb thumbdrive need to be formatted to ext4 or fat? Oh nevermind you did it differently.

Updated:

Its very extensive! thanks. I hope it works.

OK! I will have to switch GPU's and also may be reinstall ubuntu -- or just install the catalyst driver. There's a lot of junk on my system though. BUT FIRST, test it and see if it works! :)

EDIT:

No doesn't look like I need to reinstall. :'(

Got two warnings when installing openssh-server screen

cryptsetup: WARNING: failed to detect canonical device of overlayfs
cryptsetup: WARNING: could not determine root device from /etc/fstab

Should I be worried?

I personally skipped over openssh, don't worry about it.

Hey and if you want some cards, a 1000w psu, or a few mobo/cpu/ram combos, let me know.

Sweet! what GPUs are you selling? and would a good CPU make any difference to the hash rate? Are AMD CPUs good enough for this kind of thing? Does it matter if it isn't the fastest? I have 8 gigabytes of RAM in my main (and only) computer at the moment. Would 16 GB be better?

Approximately how many Bitcoins would one be rewarded in a month if mining 24/7 and how much are they worth at the moment?

It all depends on.what you setup is. But ram and CPU wont make any difference at all. My rig that I parted out has 4 5850s capable of producing 380+ mh each. I also have 3 5830s that can do 305+ each. The total is around 2500 mh. I also have 2 boards with ram, cpus, and 3+ pci express ports each. Also got a 1000w and 600w psu. If your interested in expanding ur rig, ill be glad to give a good deal to you on most parts

Good to know  :) Thanks!

I also need to know how heavy mining can be on a home network's bandwidth.

Doesn't do much as long as you setup your main computer to be on a different channel, getting the faster connection.

And would you be interested in any of the parts?
