As you can see I'm going round in circles here. The drivers just won't work with Windows 2003. I'm going to pull the card and go back to an NVidia card.

Well as you thought Boinc 6.10.60 made no difference. Installed 11-7_vista64_win7_64_dd_ccc_ocl.exe again (after trying 11-7_xp64_dd_ccc_ocl.exe and a slightly earlier version), but made no difference.

I will try an earlier driver - already tried http://sites.amd.com/us/game/downloads/Pages/radeon_win7-64.aspx

I was on 6.12.33, and had the same problem, so thought I would try the latest Boinc code. Yes I am an Alpha tester, and aware of some changes to GPU reporting, but I'm more of an intermittent tester than a regular. I'm also a CA, and test on several projects, so it's important to familiarize myself with the different Boinc versions.

I suspect this might be driver related. I'm on a 2003 x64 server and in the same way as motherboard producers dont like to offer drivers, ATI tend to bypass them. Most XP x64 drivers work, but not all. ATI offer a driver for the 2008 servers, but dont list 2003.

After a clean install of ATI drivers, Boinc is still reporting the same message. GPUz and Device manager show correct details without any problems.

I'm going to remove Boinc and then try a slightly earlier version of Boinc, 6.10.60.

From Device Manager I'm told I have 8.872.0.0 (release data 7/7/11), so that's up to date and visible to Windows.
When I tried to open GPU-Z I got an error message,
'ATI OpenCL driver bug detected, skipping OpenCL detection.
Uninstall the AMD Stream SDK / OpenCL driver to re-enable this functionality'.
When I click OK GPUZ reports that I do have an ATI Radeon HD 5800 Series GPU, driver version ati2mtag 8.872.0.0 / 2003R2. Under GPUZ's Sensors tab I can see all the usual details, Clock rates, temps, fan speeds, so this just seems to be an OpenCL bug. I take it Boinc tries to read this too.

So, does anyone know how to 'Uninstall the AMD Stream SDK / OpenCL driver', without the other drivers?
I'll do another reboot and if that does not work I will remove all ATI drivers, run driver sweeper to make sure, restart and try another fresh install again.

Thanks for the suggestion.
I already used CCleaner and did a Project reset and even updated to the latest Boinc Beta. Driver Sweeper (from your FAQ link) requires 'registration' which means giving them your details + £29.95.

Suggest replacing that with,

The Phyxion version of Driver Sweeper is Free, so I gave that a try.

Having problems with an AMD/ATI driver install.
Pulled a GTX470 and installed an HD 5850.

Tried the auto detect AMD install but had to chose XPx64, while using a Server (2003x86). After rebooting there was no indication that the drivers took, so I uninstalled all NVidia ware, rebooted and did a manual install of the driver (just the driver). While the driver is there, Boinc does not see it and reports, Caught SIGSEGV in ATI GPU detection:

Thanks Richard,

That would be perfect if it could be introduced into the Boinc Manager; an exit_when_idle button/option (Close Boinc When Tasks Finish), ideally with a text tip advising that this reports all tasks and closes Boinc.
Possibly with an additional, and shut down windows option.

I'm reporting a minor default functionality problem here. This problem has popped up in several threads recently, when the average user discovers their tasks finished but did not report.

If for example, someone selects no new tasks because they are going on holidays for 3weeks and then just shuts the computer down when existing tasks have finished (100%) and uploaded, the tasks will still report too late by the time they get back from holiday (for most projects).

So I am asking that a new default setting be created to automatically report tasks when the last task is completed, in the situation where the cruncher chooses No new tasks.

For long tasks (over 12h) it might be a good idea that these report immediately, but that's another issue. Ideally each project could be individually configured to report immediately or not.

I am aware of the cc_config.xml file and how to use report tasks immediately. This setting is recommended for some GPU projects but not welcomed by some CPU projects.

GPUGRID does not use ATI, only nvidia. It has apps for Win 32 bit, Win 64 bit and Linux 64 bit.

Yeah, for GPUGrid it's NVidia only, but there is only a Win 32bit app, and only a Linux 64bit app. The Win app works on X64 systems.
Since the majority of the work is on the GPU, there is little to be gained from a 64bit app (around 1% increase in performance last time I checked).

- Windows apps? Y
- Linux apps? Y (x64 only)
- Macintosh apps? N
- CAL/Brook+? N
- CUDA? Y
- OpenCL? N (could work on NVidia, but slower than CUDA)
- Memory Use on GPU? (Varies and depends on task type and length. Some long tasks use 650MB on a GTX470 which has 1.2GB onboard GDDR5, but they can still run on a GTX460 512MB card)
- Memory Use on PC? (Varies; Long Task uses Virtual Memory 113MB, Working set 98MB)
- Min. driver version? (197.45 for 6.12app, Fermi cards can only run the 6.13app and driver requirements vary but at least 257.21 for Win and 256.40 for Linux. Later for the 500series).
When we change to CUDA 4.0 the 6.12app will retire. This will mean updating any older cards drivers to at least 257.21 in order to support CUDA 3.1. Fermi's will hopefully work better on the CUDA 4 based app but people that don't update their Fermi driver will still be able to run the CUDA 3.1 app (6.13).
Upload sizes (worth adding) are about 28MB for the long tasks.

Hope that helps

Any chance of adding discussion links to the FAQ's listed here, http://boincfaq.mundayweb.com/index.php

With changes in architecture and advances in Bionc, some of these might need to be revisited.
For example, Allow tasks to finish when they reach 99%:
A couple of years back the associated problems did not affect as many people, but with increasing CPU cores/threads it's more of an issue, and the problems associated with this (memory for example) might become more exasperated.

Might also reduce reposts.

When a user selects No New Tasks for a project, it would be useful to have these tasks automatically report when they complete.
All complete or individually? Either would be better than the present situation; 6.10.60 does not automatically report tasks even when all tasks have finished and uploaded.

Microsoft's Windows chief Steven Sinofsky demonstrates Windows running on an Atom and 3 different Arm processors, including Tegra. Apparently, he also suggested that application and device compatibility won't be a major barrier.

Read more: Microsoft shows Windows running on ARM | News | PC Pro
http://www.pcpro.co.uk/news/364066/microsoft-shows-windows-running-on-arm

While some have dismissed these processors as being too weak or requiring too much energy, the opposite is in fact the truth. These are quite powerful CPU’s but not power hungry CPU’s. The Microsoft’s Tablet/Slate operating system requires the same hardware spec as Win7. If it’s powerful enough to run Win7 then it’s powerful enough to crunch on.

"When you think of mobile devices and slates and what we think of as PCs, they've all converged" - Sinofsky.

Obviously it is not x86 but perhaps by the end of 2012 we will be able to run Boinc on a tablet.

Post:
BobCat13, do you mean that when a task has not been started it gets resent, or some form of acknowledgement/instruction from the server to say, continue crunching same task?
When I run Lattice tasks they all go well over the deadline. They don’t reset; at least the task is not dumped and reissued (same task or new one), and I don’t start crunching it from the start again.
Lattice advise crunchers to continue running tasks past their deadline, as most go over the estimated runtime, are just as useful and people get normal credit. I think in the case of Lattice it is just down to their app and their scheduler that the % complete is incorrect. Looking at running tasks, the expected runtime might now be more accurate, for some systems, but their deadlines are still too short; I have 2 tasks at 28h on a Q6600 (stock, 4GB XP system). The tasks are at 1% complete and the estimated time remaining is about 326h. These will both finish after their deadline of the 14thAug.
Lattice may deliberately set short runtime cutoffs to force Boinc to continuously run the Lattice tasks, rather than stopping to do other tasks because switching tasks would crash the Lattice tasks/reset them.
Whatever the situation, it would be better if the projects handle their own "abort task" messages, preferably without the word abort; crunching is not a rocket mission or a birth control campaign, so perhaps Boinc should not employ such brutally worded generic messages when individual tasks reach such deadlines.
Also, if the system loses its time, Boinc aborts everything! This is a clear situation and the user should be given the choice to end all tasks, or change the time.
