Flags to Use

ATI/AMD Radeon HD 5xxx cards (for example, HD 5770): use '-v -w128'

('-v -f10 -w128' works even better for HD5770.)

If you find the desktop laggy while mining, use '-f60'. This may decrease performance slightly.

Please update this section if you find better settings, or good settings for a card not listed here.

OpenSUSE

This works on 11.4, it might work on other versions (11.3 is more than likely to work) just replace the "11.4" in the repo URLs with your version number. This also assumes that you are already familiar with running getting the BitCoin client running (to run the GUI version on OpenSUSE you will need libpng12-0 installed).

Add the Python devel repo:

# zypper ar -r http://download.opensuse.org/repositories/devel:/languages:/python/openSUSE_11.4/devel:languages:python.repo

and this user repo, which provides PyOpenCL (take a moment to appreciate this because if "scorot" didn't package it this would be a lot harder):

# zypper ar -r http://download.opensuse.org/repositories/home:/scorot/openSUSE_11.4/home:scorot.repo

Refresh your repos:

# zypper ref

You will asked to accept the repo keys, respond with 'a' each time.

Install PyOpenCL:

# zypper in python-pyopencl

Get the latest version of poclbm with git (`zypper in git` if you don't have git installed):

$ git clone git://github.com/m0mchil/poclbm.git

This will create a poclbm folder in your current directory. Change to it:

$ cd poclbm

And run it:

$ python poclbm.py --user=user --pass=pass --device=0 [add whatever other flags you use]
