openCL problems

[Damsho]

Hello there!

I've searched for this the whole day already but can't find the solution..

My GPU is a HD 6870 reinstalled the computer and installed all the drivers.
I also installed the driver update..

But my GUIMiner is still giving me the message No openCL device.
I also reinstalled the GPU already but no effect..

Hardware info:
-Recom Voeding Power Engine 600 Plus 600W
-Kingston 1x2GB, DDR3 SDRAM, PC10666, CL9
-AMD Sempron 145 2.80GHz 1MB AM3 Box
-ASRock N68-VS3 UCC nForce 630a, SATA300 RAID
-Asus Videokaart PCI-e Radeon HD6870 DirectCU 1GB 2xDVI/2xDP

Can someone help me out?!

Have you installed the SDK?

[Damsho]

Yes installed SDK 2.0 and still not working..

Yes installed SDK 2.0 and still not working..

2.0?  Sure about that?

[Damsho]

Yes I'm pretty sure about that.. Check the screen picture.

Just reinstall drivers. I got same situation in past, and reinstalling was helped.

[Damsho]

Gonna try that again now. Should I after deleting them download the latest drivers from the internet? Or should I start installing from CD and then update?

[DeathAndTaxes]

Yes I'm pretty sure about that.. Check the screen picture.

That has nothing to do with OpenCL.   That is .NET.  

Look over on the upper right on GPU-Z where OpenCL is unchecked.  You don't have ANY OpenCL SKD/runtime installed.


You can get it as part of drivers or separately from AMD website.  You don't want SDK 2.6.  That means don't install drivers (until you learn how to only install driver not SDK) 11.12 or higher.

I can't get it done.. is there anyone that would like to help me trough teamviewer?

Uninstall ALL ATI software, restart.
Install http://www2.ati.com/drivers/hotfix/catalyst_11.11_hotfixes/amd_catalyst_11.11c_windows_vista_7.exe
Restart.

That should do it, anything else is a problem with how you are using Guiminer, such as selecting the proper GPU and mining kernel.

[Damsho]

Does that download support windows XP?

[Damsho]

Argh... did what you said still not working.. I offer 0,3 BTC for the one who solves my problem through teamviewer!

Does that download support windows XP?

As the file name implies, that is ATI Catalyst 11.11c for Vista and Windows 7; here is the link to the Windows XP driver (which includes SDK 2.5 and is all you need): http://www2.ati.com/drivers/hotfix/catalyst_11.11_hotfixes/amd_catalyst_11.11c_windows_xp.exe

"Uninstall first" also means uninstalling all other ATI software including any other SDKs, which may only have uninstall links in the start menu, not in the control panel "add or remove programs".

After installing, your GPU is normally the first OpenCL device, but if you have onboard video + a compatible CPU, the GPU card might be OpenCL device 0, 1, or 2, which you will need to specify in the miner.

[Damsho]

Ok this is odd..

The steps I took:
1. Uninstall all ATI software including other SDKs
2. Restart
3. Insert the driver CD installed the driver
4. Restart
5. Download that ATI Catalyst 11.11c for windows XP
6. Installed it
7. Restart
8. Tryed to launch GUIminer

AGAIN error that there are no openCL devices..

How can this happen.. I installed this card while ago in another system there it worked fine with GUIminer..

[deepceleron]

1. Uninstall ALL ATI software, restart.
2. Install http://www2.ati.com/drivers/hotfix/catalyst_11.11_hotfixes/amd_catalyst_11.11c_windows_xp.exe
3. Restart.

The steps I took:
1. Uninstall all ATI software including other SDKs
2. Restart
3. Insert the driver CD installed the driver
4. Restart
5. Download that ATI Catalyst 11.11c for windows XP
6. Installed it
7. Restart
8. Tryed to launch GUIminer

You made up step #3! The linked download IS the driver, whatever is on the CD is going to be years old, and is what you were uninstalling. When you restart after uninstalling the old drivers and get the wizard prompts, you just need to cancel them.

One thing that is so obvious to most but may have been missed: disable the onboard video in the BIOS (Advanced->Primary Graphics Adapter->PCI Express). Plug the monitor into the GPU card, not the motherboard.

I hesitate to post this, since it has even more steps, but if you still have problems, here's a post I made about how to clean up all your old ATI stuff and fix your driver install: https://bitcointalk.org/index.php?topic=63616.msg745198#msg745198; install the XP driver I linked above instead of the Windows 7 driver.

Thanks for your reply mate will look into that tomorrow!

Don't worry.  I thought I was fairly proficient with computers until I learned about Bitcoin and tried to start mining.  It took me between 3-10 hours to get myself up and running (depending on if you take into account all the Bitcoin research I did immediately prior to setting up my miner).

This stuff isn't easy, and anybody on this forum who claims that it's easy lives in a bubble.

This is driving me nuts.. It's still not working deleted all ATI software and went into BIOS to set main to PCI-E.
Also only installed the drivers from that link.

I have no clue what the problem is..

I have also all the time the screen plugged in the GPU it self.

If you have the 11.11 drivers currently installed (to avoid more reboots), you can send me a Windows XP remote assistance invitation, and I'll take a look at what's up on that PC.

Sent you the invitation if I done it right..
