So I have a work laptop. It's my personal laptop that I use at work. It runs 5-10 hours a day 4 or 5 days a week. Just plugging along using someone elses power looking for ET right?
Anyway I hadn't updated it so it was running mostly AP work units. Yesterday I updated the optimized app and noticed that the gpu work units were blowing through at a minute or less. DAMN this v.41 is faster. Now they are mostly inconclusive and invalid results. WHY? When I looked at my desk top with the radeon card the same type of work units were taking about an hour.
Should I uninstall and reinstall everything? Help... stuck...

You have 2 problem Computers:
NVIDIA driver 320.18 have bugs (especially for 2 GPU systems):
Update to 320.49
Again driver problem:
AMD/ATI driver 1.4.1589 (= Catalyst 11.10) is old
The minimum needed for current SETI apps is Catalyst 11.12
Use this table for info and links:
! If the laptop is 'special' you may need drivers from the laptop manufacturer and not from AMD/ATI
(There may be other problems but it will be unclear until the drivers are updated)
You didn't read the docs:
"ATI MB apps - r1843; AP apps - r1843
Minimum required driver:
All OpenCL applications are compiled under SDK 2.6 so minimum driver is
Catalyst 11.12 Accelerated Parallel Processing (APP) Technology Edition

The driver was only part of the problem... I updated to 13.4 however I kept having the same problem 20-60 sec workunits. My driver info wouldn't update on the seti site either. I clicked update on the project tab, tried restarts, but the old driver kept showing for my computer.
The fix was a uninstall of BOINC and APPs as well as a manual delete of the program data files. Reinstall and all is well and running smoothly!
I fixed the nvidia driver on my desktop at home as well.
Thanks for the help!
I didn't read the readme file. I just figured all worked well under v.40 so v.41 should be the same with the v7 update. I'll be more careful in the future.
