Getting the PPSieve WUs to run on ATI cards

[Harley]

I installed the 10.12 drivers on 12/13 and I used driver sweeper first! Still having the same problems! This box must be cursed.

YES,YES,YES!!!!!!!!!!!! Got it working. 2 more 5970's ready for the challenge! Looking good. I have them clocked at 935 with no errors.

I'm always a fan of those magical dances that get computer stuff working. Congrats!!!

Ok, what is driver sweeper? I'll give the 10.12 a try but I guess I need to clean up the existing drivers first.

Good to hear.

Driver Sweeper cleans out all the residual file from prior driver installs. Helps avoid "issues" with installs. Uninstall driver, run Driver Sweeper, install new driver. Should make it standard practice...

You can download it here (go for version 2.7.5): http://www.phyxion.net/Driver-Sweeper/View-category

Okay the verdict is in: Run the app_info with count set to .5! I see a 4% increase in GPU loading AND it directly translates to 4% lower wu run times! My 5870s dropped from 960s per wu to 922s.

I also set the cmdline to p3 b-1 but I have no idea if that actually does anything. It doesn't hurt though.

Interesting. Do you think it's worth trying the opti_app on either of our rigs? Mine w/ dual 58xx and Kat's w/ dual 48xx. If you think it's worth it I'll give it a whirl tomorrow after work - I mean 4% is 4%...If we lose by that much I'd be grumpy that I didn't do it!

In a last-ditch effort to help anyone still having problems with the ATI cards and PG's app, here's a PM I just got from Harley, posted with his permission:

What I had - 10.12 with CCC beta. [NOTHING had worked for him at this point]

What I did - Step by step.
1) Removed 10.12 by using the 10.12 download.
2) Rebooted into safe mode.
3) Used driver sweeper in safe mode to remove remaining ati bits and pieces.
4) Rebooted normal mode.
5) Installed CCC 10.11 Accelerated Parallel Processing (APP).
6) Rebooted normal mode.
7) Downloaded and installed CCC 10.12 Accelerated Parallel Processing (APP). NOT THE BETA VERSION OF CCC.
I did this without removing any part of 10.11.
8) Rebooted.
Started Boinc and everything worked. That's it.

I hope this helps. Harley.

Any of you whizards have an app_info for ATI that will crunch both CPU and GPU? I would rather someone give me one rather than me having to actually think through it Every time I try to think it gets me into trouble.
