That was enough to determine that the HD 7970 is not suitable for my computers.

Close enough to hope that the HD 7950 might be, though.

Message 52573 - Posted: 19 Jan 2012, 9:30:59 UTC

I installed a bare hd 5850 oem vendor id ati(1002), and preceeded to download and install the most current Catalyst from ATI. When all was said and done, winxp 64-bit saw it fine but BOINC found no usable gpu! I use my gpus strictly for BOINC and don't play any games but I assume that the card's performance is up to the specs. These cards appear to have been retailed through Comp USA, Tiger Direct, and likely other sources, but never seem to come with a driver disk, just adapters and crossfire hardware. Does anyone have one of these things up and crunching on a winxp 64-bit box? I'm thinking since the drivers are for win 7 and Vista that something just doesn't come out right. I suppose placing the card in a win 7 system would likely solve the problem, but that is not an option at the moment.
Any comments would be appreciated.
Thank you

An HD5850 card is double precision and should work fine at Milkyway. I run one on Win 7 64 bit with driver CCC 11.10 without any problems. As far as I know Win 7 64 drivers wont work on Win XP 64.

Unload current drivers and load these :

Note in particular:

"The AMD Catalyst™ Control Center / AMD Vision™ Engine Control Center requires that the Microsoft® .NET Framework SP1 be installed for Windows XP and Windows Vista. Without .NET SP1 installed, the AMD Catalyst™ Control Center / AMD Vision™ Engine Control Center will not launch properly and the user will see an error message. "

Post again in Number Crunching Forum as a new thread if you still get issues

I got the same problem, running on win 7 64 bit. Everything was workning fine until i downloaded and installed AMD latest driver(12-1_vista_win7_64_dd_ccc.exe). Now, boinc say that no double precision hardware is present.

I went back to the old driver as a test (11-12_vista64_win7_64_dd_ccc_ocl.exe) and everything is working again.

Looks like AMD changed something in the card identifier that your application cannot recognize, therefore idenfying the GPU as incompatible.

I have just updated my 4850 card from Catalyst 11.5 to 12.1 and now Milkyway@home reports errors. Which driver version should I use?

Looks like the 48xx series does not like the newer drivers as my HD5830 has no problem running Milkyway with the 12.1 preview drivers.

Message 53000 - Posted: 10 Feb 2012, 4:50:49 UTC

Help!
I have two ATI FirePro 3D V8700 gpus which just got knocked out of the project because of the changes in work units. I don't believe it's the changes per se which are the cause of this, but the inability of BOINC to correctly identify the gpu.
Ever since I installed them over a year ago, BOINC keeps reading them as HD 4700/4800 gpus. I am still plagued by messages from WUprop@home saying would you please identify your gpus because of this failure. This has happened with the last three versions of BOINC I have installed, choices are limited because I run 64-bit versions of win7 and xp.
With the changes implemented to the new wu's I have now started to receive the following message from mw@home: "Catalyst driver version is not okay for OpenCL application with this GPU."
The only upgrade for OpenCL for this card is 1.1 from 2010. I updated the Catalyst Center to the most current version, which installs version 1.1 by default. Nothing further is available until they come out with version 1.2, scheduled in August.
I think if BOINC would accurately identify the GPU everything would work fine. These were both exceptional cards completing a wu in around 3 minutes prior to the change.
Any assistance would be appreciated.

Thank you

For an R700 GPU like you say you have, it should accept it if your Catalyst version is between 11.7 and 11.9 or >= 12.1. The OpenCL version isn't important; only OpenCL 1.0 features are used. Which version were you trying?

It looks like all of the 7000 series will be able to crunch here as even the 7750 has a double precision floating point.

Yes they can crunch here, but the HD 7750 and HD 7770 models will do so relatively slowly. Double precision FP values of 51.2 and 80 for HD 7750 and HD 7770 are lower than a HD 3850.

You are probably aware of this arkayn, I was just pointing it out in case anyone decided to rush out and buy a 7750 or 7770 for MilkyWay.

Yes the 78xx models should have excellent performance/watt on single precision projects. MilkyWay too if double precision is one quarter of single precision like 79xx models.

I haven't been following developments so I don't know if Pitcairn 78xx models will have double precision of one quarter or one sixteenth like the 77xx models. If it is only one sixteenth, then possible future Tahiti LE model (7890?) would be the better choice for MilkyWay.

Don't throw away your 5800's just yet; the 7800's FP64 (single precision) is 1/16th FP32 (double precision) >:((

Hello, I have GeForce GTX 580 card. Few weeks ago I updated nVidia display driver to ver 295.73. Since then I've experienced a lot of problems crunching fast GPU tasks. "Computation error" - that's the NORMAL message I see last weeks. When will you update your GPU tasks to fit the new driver requirements? Thank you.

It is not the app but the driver causing the problem, when the monitor goes to sleep it is also putting the CUDA card asleep and causing the tasks to error out because there are no capable CUDA cards.

You will either need to turn off display sleep and manually turn off the monitor or go to an older driver.
