I have two machines that behave totally differently under this python client.
They both have the same hardware and OS:
AMD Semperon Single core
1GB RAM
ASUS ATI Radeon HD 5850 overclocked to 950mhz
One machine does 300-305mhash/s and stresses the gpu to 94-97%
The other does 282-289mhash/s and stresses the gpu to 89-91%
How do I increase my slow machine to get the extra 20mhash? Is there a command line way to tighten the processing loop?

has ANYONE got this working on a nvidia card ?
On a more related note, I get this error when running m0m's release (8800 GTS, Driver 258.96)
Code:
C:\Users\Owner\Desktop\BitcoinOpenCL>poclbm
Traceback (most recent call last):
File "poclbm.py", line 46, in

I get something very similar on a 9400GT, but in linux! No idea how to fix this.
Jim, I don't know where to help from here. Two other people have OpenCL support on their Nvidia card, and still can't get it to work. Without having a set in front of me, it's hard to troubleshoot it. I do have an Nvidia card, same one as you just about, but I don't know if I'm going to swap it out to test. I'm sure our set up varies greatly and I don't know if I would be able to make any beneficial advancements doing it, sorry.
It's ok. I'm sure something awesome will come out, but I'm happy to test this for momchil. thought my 8800 would have OpenCL support but it doesn't. Thanks anyway.
Mine's an ATI 5870.
...
run that and see if it shows OpenCL is supported. Give us a screen shot. There are some trouble shooting steps on their website.

Wow, nice!
Here's my screenie:
ok , i have no opencl support (see image) 
i get similar results with my nvidia card
here's a screenshot of Caps Viewer and GPU-Z (for driver-info).

here's a screenshot of Caps Viewer and GPU-Z (for driver-info).
I get a 2-3% increase on the new version. Not much, but a consistent increase. I have my hashes scaled back to about 150/m so this increases it to about 153/m.
It jumps around a little bit of course, but I don't really see it dip below 153/m
Edit-
Don't get me wrong either. 3000k/hs is an extra block a month so no complaints!

Wow! What hardware are you running?

Jimbo, please try this and see if the tool shows OpenCL is supported. It would be helpful if you post a screenshot.
I went home for lunch and I am physically at my computer...back to work for me. I have not tried puddinpop's client.

I completely misunderstood you sorry.
So you did not compile the dll's yourself for boost? So you might have a problem with your boost path.
What happens when you run the bootstrap in the boost directory?
Then here is what I used to build the boost libraries after bootstrapping:
That then created a directory starting from c:/boost called C:\boost\stage\lib that had the dll's in it, and is how I pointed it inside my site.conf
Then I copied those dll's over. I am wondering if the dll's you downloaded aren't the right ones or don't have all the right flags or something.

I believe I have the right flags. In the installer I picked msvc 2008, python, date time, and thread. There is no option for threading or link.
I did not do the bootstrap methon. I used the win installer with the precompiled binaries from here http://www.boostpro.com/download/ (that was what the boost site said to do).
I reinstalled Python26, Numpy, SciPi, and boost 1_39. I copied all the dlls into the same folder as poclmb.py.
Still same error.
Hmmm...

I went home for lunch to debug but now I am at work. I am hardcore to get this to work. Will work in it tonite.
Awesome, so you got it working with a CUDA card?
Specs and hash rate?
Specs and hash rate?
Oh, not yet...sorry if it sounded like I declared victory too early. I still get:
Code:
ImportError: DLL load failed: The specified module could not be found.
Any ideas?
Post your boost version, siteconf, and os. Should be able to help you more from there. Make sure you grabbed the right dll's because several of them are named close.
I am using Windows Vista 64-bit. I used boost 1.44, but there was an error so I actually downloaded the binary versions of "boost_python-vc90-mt-1_44.dll" and "boost_thread-vc90-mt-1_44.dll". I used all 32-bit installations for compatibility. Below is siteconf.py. I was able to run "python setup.py install" ok without errors.
Code:
BOOST_INC_DIR = ['C:\\boost_1_44_0']
BOOST_LIB_DIR = ['C:\\boost_1_44_0\\lib']
BOOST_COMPILER = 'msvc'
BOOST_PYTHON_LIBNAME = ['boost_python-vc90-mt-1_44']
USE_SHIPPED_BOOST = False
CL_TRACE = False
CL_ENABLE_GL = False
CL_INC_DIR = ['C:\\Program Files (x86)\\NVIDIA GPU Computing Toolkit\\CUDA\\v3.2\\include']
CL_LIB_DIR = ['C:\\Program Files (x86)\\NVIDIA GPU Computing Toolkit\\CUDA\\v3.2\\lib\\Win32']
CL_LIBNAME = ['OpenCL']
CXXFLAGS = ['/EHsc', '/DBOOST_PYTHON_NO_PY_SIGNATURES']
LDFLAGS = ['/FORCE']
Thanks for your help!
looks like a dll is missing
which boost version are you using ?
best is to post your siteconf.py

Copy your boost_python-vc90-mt-1_44.dll and boost_thread-vc90-mt-1_44.dll that you compiled with boost earlier directly into your directory where you are running poclbm.py from.
I don't speak German, but that looks like what it is saying to me.
I also get this error. I tried copying boost_python-vc90-mt-1_44.dll and boost_thread-vc90-mt-1_44.dll directly into the directory where I am running poclbm.py but it has the same error (see below). I copied it into Windows\System32 but still same error. Any ideas???
