wow that was exceptionally hard!
install, reboot, uninstall, reboot, safe mode, wipe drivers, reboot, uninstall again for shits and giggles, fix registry, reboot, surf web, install, reboot, uninstall, reboot, surf web more, install, uninstall, install, uninstall, install, uninstall... 0.o reboot.
realize no one on the net knows anything about this. (remembers why nvidia was so nice)
find out 2 installers exist, but only one works, 2 completely different names. ()
post here...
go directly into crazy long string of jibberish c:\ati directory find opencl.msi, try to install and get cock blocked, uninstall, reboot, go directly back into into crazy long string of jibberish c:\ati directory something find opencl.msi, go back a few levels, trick retarded installer into installing opencl directly.
go to command prompt then to phoenix, run it, still goofed up, run caps viewer, opencl is checked.
Start wondering if I'm on acid. decide I'm going to go to sleep, decide to try guiminer, and it works.
WTF?!
check with AMDGPUCockTool.exe
things are good
insert good flags into guiminer "-v -w128"
Win.

anyone know where I could extract the latest opencl.dll
the ATI installation with driver and CCC and then the current AMD STREAM SDK does not include it or put it anywhere I have been able to find.
However, nvidia drivers include it and so I'm getting ready to try using one I found from 2010 on my system.

Dummy plug makes no difference. Still need help! Will offer a reward!
Update your drivers then try each card by itself in each slot. So, 2 cards and 2 slots means 4 different tests. If all 4 tests pass then put the cards in at the same time in CrossFireX mode and try playing a game with the load balancing meter on. If the game works then try a different miner. If none of that isolates the problem you might try another set of cards or a new motherboard. Good luck.

I figured out only one of the cards gives the Verification Failed error. They are both well cooled and not OC'ed. What should I do? I have a dummy plug, but I can't tell if I did it right or if it is working. Should I just get an RMA? Help!

Hey guys, I just finished building my first rig but have encountered a problem. Whenever I try to run both my 5830s in Crossfire mode enabled, only one runs. Whenever I try to open up a new instance and a new worker with --device=1, poclbm crashes after the first block and says verification failed, check hardware. With Crossfire disabled, the miner will only work using one card. When I open two, they both crash down to 50 kh/s. All the stuff above is WITH the crossfire bridge on the two cards. Without the bridge, one card works, but whenever I try to open a second window of the miner with a different worker and device, it simply divides the use of one card. Help please!
EDIT: The verification failed thing only happens when the second miner finds its first share. Before that both cards run at 200 mh/s.

I can't even get past the stage of making bitcoin.conf. I make that file, then try to run:
bitcoin.exe -server
A Bitcoin error says : "Warning: To use the "-server" option, you must set rpcpassword= in the configuration file:...
If the file does not exist, create it with owner-readable-only file permissions."
**edit: Notepad was adding a .txt file extension, which wasn't showing up. Watch out for that, folks
And thanks for the writeup!

Sorry. Lesson learned - do not go to Lenovo for ongoing graphics driver support. NVIDIA had me download 266.58 for GeForce, and I'm off and running. We'll see how it goes!
April 06, 2011, 12:59:10 PM
I'm a bit confused... I have an NVIDIA Quadro NVS 140M GPU on a Lenovo T61 laptop. NVIDIA says it supports CUDA and I downloaded the latest driver (I think - 7.15.11.7693 (11-14-2008), R0.00 (branch: r176_50-10501)). The Caps Viewer shows I have no CUDA/OpenCL support. What do I need to do next?
Thanks.
Thanks.

My video card is an ATI Radion HD3300
the HD3xxx doesn't support OpenCL (can't use my HD3870 for mining), you'll need at least a HD4xxx.
Not to be contradictory, but the standard download from ATI for my card includes OpenCL support and the GPU Caps Viewer confirmed that I have OpenCL support. Perhaps it doesn't have full OpenCL support? Or something related to OpenCL isn't fully supported? I'm just throwing some ideas out there. Does anybody know more about this?

This is probably a power or heat issue resulting from your GPU running at full load. What power supply are you using?
Yep *dust*, you're correct; thx! Power supply is 350W; GPU Cap shows it at 84C at rest (it's a Dell Studio XPS Desktop 435MT). I took a vacuum and compressed air to it and, under full load it runs at about 120C...but it's running (30min now...)

I have done all in the tutorial and still my ati card doesnt show up only my quad core... any idea ?
What do you mean "doesn't show up"? More info describing the exact problem you are having would be helpful.
Additionally, does anyone have any input regarding the use of the ati stream sdk 2.2 for amd devices? Some people in IRC today told me that 2.2 may not necessarily be the ideal choice or even necessary for use. I do not have an ati device to test this on and I would appreciate any feedback so that I can ensure my guide is as accurate as possible...
I might be having the same problem as sonihr. When I try to execute the batchfile in the command prompt without indicating a device (excample: poclbm.exe --user=user1.user2 --pass=password --host=mining.bitcoin.cz --port=8332), I get the following message:
"No device specified or device not found, use -d to specify one of the following
- AMD Phenom(tm) II X4 955 Processor"
I think my video card is supposed to be showing up on this list. My video card is an ATI Radion HD3300. It's integrated onto my motherboard. I've updated Catatlyst to the latest suite, which includes OpenCL support and confirmed that I have OpenCL support with the GPU Caps Viewer. I've been using my CPU so far and it's been working at about 3100 khash/s. So, how do I choose my GPU, instead of my CPU?
Also, is it possible to use both my CPU and my GPU at the same time?
Thanks in advance!
If you want to just use the CPU, the stock bitcoin client uses the CPU when you click "generate coins".
As far as onboard graphics...I'm not too sure, I would suggest trying using different numbers as arguments when you specify --device=X
For example, I have 2 graphics cards so I have one line that specifies --device=0 and then another for --device=1 to use both of my cards. Try changing the numbers around a little bit, maybe onboard graphics is device 1, or even 2?

and ran it again and it started without asking me the username etc, so it seems important to have the ---device bit before the rest of it.
This may depend on your card... I launch mine via the batch script like:
start /DC:\Users\[username]\Desktop\poclbm_py2exe_20101218 poclbm.exe --user=user --pass=pass --device=0 -w 256
And it works...I guess your mileage may vary
December 20, 2010, 04:52:43 AM
Okay I think I'm in business. I downloaded and installed new drivers. I ran the batch file and it still didn't work, but the cmd window it flashed didn't flash quite so fast and I could read the name of my vid card in it at least. The I went back to the bitcoin\poclbm_etc directory and ran "poclbm.exe --user= etc" and that didn't work either, but it did give me another error that said:
No device specified or device not found, use -d to specify one of the following
Then I played around with that a bit until I got the syntax correct and then it asked me for my jsonrpc username and then password. I put them in, it chugged a bit and now it is giving me a khash/s value so I am good to go.
I also just rewrote my .bat file to read:
start /DC:\bitcoin\poclbm_py2exe_20101218 poclbm.exe --device=0 --user=youruser --pass=yourpw
and ran it again and it started without asking me the username etc, so it seems important to have the ---device bit before the rest of it.

The link is correct, yes. It worked after I installed this SDK and rebooted. As I said, I also wiped my old nvidia drivers, but I don't know if this step was absolutely required because I didn't test the intermediate stage. Apart from that, no other steps were required.
I'll post a comment once a block gets generated So far got nothing; there was a 50% chance of having generated something in the last couple of days.

Added a link to http://www.ozone3d.net/gpu_caps_viewer/ on the blog post, also noted that my setup involved nvidia cards when writing the guide.
Are any additional steps aside from the sdk installation needed if someone is using amd/ati cards? Is this the link that I should post on my article? http://developer.amd.com/gpu/atistreamsdk/pages/default.aspx#five
My setup was done with nvidia gtx275 cards and I did not need to do anything "special" aside from obtaining recent drivers to get things working, thanks for pointing out that there are additional steps for ati users.
Also, thanks for the input, I'd like to have as complete a guide as possible
romkyns, also, if you could post a new comment saying that you got it to work on my site I would appreciate it

(post rewritten)
Here's what I did to get it to work:
- Run GPU Caps Viewer to confirm that there is no OpenCL on my system at the moment.
- Use Driver Sweeper to kill my old nVIDIA drivers (no idea if it would have worked without this step)
- Install ATI Stream SDK 2.2
- Reboot
- Verify in GPU Caps Viewer that OpenCL 1.1 is now installed.
Importantly, ATI Stream SDK 2.1 / OpenCL 1.0 did not work, with a very similar error message. Thanks to m0mchil who helped me out over PM! Getting 150M hash on my HD5770, which is pretty cool if the number isn't lying. The OS remains perfectly responsive.
LobsterMan, if you could, please mention in your steps that Radeon owners should install SDK version no lower than 2.2.

Search for 'GPU caps viewer' or other tool to check if your setup is OpenCL enabled. With AMD you need Stream SDK installed except you are using catalyst 10.10+, 'Accelerated Parallel Processing (APP)' flavor.
LobsterMan, please mention in your article 'GPU caps viewer' or something similar as a way to confirm OpenCL is working.
