python OpenCL bitcoin miner

[FireFox31]

Hello, I recently upgraded from poclbm_20110325 to poclbm_20110428 and I'm now receiving "long poll exceptions" once every hour:

10/05/2011 14:05:19, long poll exception:
Traceback (most recent call last):
  File "BitcoinMiner.pyo", line 259, in longPollThread
  File "BitcoinMiner.pyo", line 222, in request
  File "httplib.pyo", line 974, in getresponse
  File "httplib.pyo", line 391, in begin
  File "httplib.pyo", line 349, in _read_status
  File "socket.pyo", line 397, in readline
timeout: timed out

On the older version, I had no problems, though I was generating about 4% stale shares.  I hoped the newer version would reduce stale shares.  I'm running Windows XP, a GTX460, and poclbm on GPU mining.  Is this a problem?  Is there a fix?  Thanks for any help you can provide.

I didn't read the whole thread, so, please forgive me if this problem has already been addressed (in that case, I'll look for the solution by myself).

I'm mining on a Debian box with a 5970. I'm prudently trying to overclock it, but I run into a problem.

The hashrate in the shell of the second core sometimes gets stuck. CTRL+C is ineffective to quit (I get the "Bye" message, but I dont go back to the prompt).

If I close the shell and confirm that I want to kill the child process, the whole graphical interface freezes. It happened twice at two different clock rates (800 and 780) even though the temperature monitors reported ~66 °C. The second time I actually tried to kill the process from the shell.

At the time, I didn't think of pressing CTRL+ALT+F1 to launch a shell outside of X, and rebooted.

I went back to a lower clock rate, and everything is fine, but I'm curious about the cause of the freezing of the process, and the of the whole GUI.

i've got a bug to report.
so there was an exception

and mining stopped, had to restart it.
probably relevant dmesgs:

If I put & symbol in the password after --pass option the script says Bad password. Should I try the password with quotes?

Yes

I have a problem. I got an XFX 6850 card overclocked to 900 core clock and 1150 memory clock with SDK version 2.4 and driver version 11.4.
When I try to use poclmb, I can't get more than ~2 Mhash/s! But when I'm using DiabloMiner I get up to ~200 Mhash/s. Anybody know whats causing this?

You probably have the CPU selected as the device to mine with. Change your -d/--device setting. For SDK 2.4 device 0 should be the first GPU. (it's 1 on earlier SDK versions)

So I should just add -d 0 to the command? Okay, I'll try that!

Edit: Yes! thank you! Now I get ~230 Mhash/s

Edit2: Okay, I got another computer with a sapphire 5770 card running with no overclock, SDK version 2.1 and driver version 10.11 (Because I read that these were the best ones on 5xxx cards, is this true?), and when I try to start poclbm, I get this error:

Code:

Again, DiabloMiner works fine :/

Just thought I would report my results on a 2011 MacBook Pro, running an AMD Radeon HD 6750M, in Windows 7 (Pro 64bit), SDK v2.4, -v -w 128 = about 72 Mhash/s

[Hello]

Hi all
I have radeon mobile 5650.
Try to run, but have error

This OpenCL build requires version 1.4.879, version 1.4.692 installed

I install lasst drivers (11.5) and last AMD APP SDK from http://developer.amd.com/gpu/AMDAPPSDK/Pages/default.aspx
Can you help me?

[raffomania]

Hey,
I use an AMD Radeon X1900. gpu caps viewer says that it has OpenCL 1.1, but at the OpenCL-tab it only displays my AMD Athlon dualcore CPU. When I try to mine at deepbit.net, I always get the "authentication failed, check hardware" error. What can I do?

Thanks!

What is wrong, and how to use 100% of GPU ??

[marcus_of_augustus]

-f1

[biochem]

-f1

it is significantly  better now!!!
I've got 85%  on average now!!!

PS. mining in the slush pool.

EDIT: you sound like a noob so you had better read the OP (and whatever else you can get your hands on) ... and watch the temp.s if you are going to thrash these cards with mining or you'll fry your cores....

$aticonfig --adapter=all --odgt

get nervous with core temp above 80 C ... I keep mine 70 or below.

-v drop GPU consumption to 70 on average.

I've got few boxes with 2x5970 under archlinux and ubuntu, running for months  and never have such problems like I've got with 6990, so I'm completely disoriented 

And I keep temperature automatically by changing corerate

Okay, sorry about the noob comment then.

I would have thought the 6990 was v. similar to 5970 but there ya go. I think it sounds like from some of the other threads that SDK 2.4 and 11.4 driver is better with 6990 ... also maybe phoenix miner might be different  with high AGGRESSION setting ...

Sorted!
SDK 2.4  give more than 95% for each GPU on 6990, while SDK 2.3 only can do no more than 65% of load....

What's "corerate" ... is that utility in linux?

No it is core rate, nothing to do with any linux progs.
