I have cold rebooted a few times with no loss, so hopefully this will work! The major test is an overnight shutdown.

I have been looking through the web and found that people do have a problem with this happening. So I ran a program that removes the install information (after un-installation) to remove any pointers to corrupt files and settings! This seemed to do the trick! I am now testing the PC again for any further defective drivers and OPenCL problems! I did notice that ATI have released an openCL update which is on the Lunatics website so if this fails again I will try using that version instead.

Incidentally, I am running Lunatics as mentioned in my earlier posts, which should not work but does as using any other settings fail. I am keeping everything I can cross crossed!

When you say it loses OpenCL what do you mean? Does the GPU just not show up in BOINC or does OpenCL stop working in some way?

When you say there is an OpenCL update what are you referring to? I don't see any mention of it on the amd or lunatics websites.

In other news the four I did are complete. One validated against a Nvidia GPU where we both got -9. So hopefully that is actually a noisy one. One of the two that ran for 4-5 hours is paired with a machine is only has about a 7% valid rate. So that one will probably take a while to confirm.

Thanks Sten but I am not 100% confident in the AMD card as they seem to lack a little something and AMD seem to always mess up their drivers! Nvidia don't seem to have a problem like AMD does. I of course may change my mind upon the results etc.

I've been using ATI cards since the first Radeon. I like to refer to these "problems" as a tradition.

HAL lol, you're a bit of an AMD/ATI dinosaur then :) Seems strange that they cannot get their act together like Nvidia! Especially as they are now made by AMD.

Nvidia isn't so innocent either. I have had their cards in other machines or work boxes over the years. Once of the most amusing things they did was release a driver that trashed the system when you installed it. I had that across multiple machines with different cards in different OS's when setting up test machines at work. IIRC it was around the 154.xx driver release time frame.

I have Private message from Raistmer (the programmer of OpenCL apps)
I think this message is not secret so I share it:

BilBg:

Subject: OpenCL_r390 + Max work group size 128 - seems to work OK

You can see the clues here:

http://setiathome.berkeley.edu/result.php?resultid=2344581713



Raistmer:

Hi.
The problems only with HD4xxx GPUs and some weird lockups our testers see time to time.

In general it should work indeed.

Luckily I am not seeing any issue like that. I just have the problem of once windows disables the display the GPU clocks down. Since this is in a notebook I'm not leaving the display on 24/7. Once I get all of the GPU tasks out my lappy wont be running it anymore, but good to see it works. Hopefully they will update the release notes with the next installer release.

If somebody could fill me in into what exactly needs to be updated?
I'm not omniscient and I don't run ATI so I don't have first hand knowledge of the traps. If nobody tells me what needs updating and with what, updates don't happen.

I would have guessed that Raistmer would provide the updated info/changes for the read me.
The section of the read me that reads:
The ATI MB application will not work on ATI cards with workgroup size 128
(e.g. HD43xx). To check workgroupsize run CLinfo, downloadable (at present)
from {http://boinc.berkeley.edu/dl/clinfo.zip}
If you have problems running the HD5 flavour (anything from reduced performance
to BSOD), you should run the plain variant.

Would need to be changed. It seems the statement does not apply to HD53xx & HD63xx hardware. Perhaps "The ATI MB application will not work on ATI HD4xxx cards with work group size 128, but will on HD5xxx cards with work group size 128."

Message 1205256 - Posted: 12 Mar 2012, 21:10:05 UTC - in response to Message 1205231.  

Once I started up the PC this morning all worked ok, so the issue I had was originally with the first install whereby once updated automatically it caused a problem with any re-install of the drivers and OpenCL, where it disabled it on any future restart! I cured this by deleting the current driver then running the app Msicuu2 which basically removes any corrupt installations totally from the system. Once this has been done reinstall the required driver and there you go all up and running without any issues!

I hope that helps anyone else having a similar issue! Unfortunately I cannot remember where I downloaded the file from but you can get it here http://www.filecluster.com/downloads/Windows-Installer-CleanUp-Utility.html If I come up against anymore issues like this with this card I will post it here!
