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...

Thanks

You have 2 problem Computers:

1) http://setiathome.berkeley.edu/show_host_detail.php?hostid=6625355

NVIDIA driver 320.18 have bugs (especially for 2 GPU systems):
http://setiathome.berkeley.edu/results.php?hostid=6625355&offset=0&show_names=0&state=6&appid=

Update to 320.49
http://www.nvidia.com/object/win8-win7-winvista-32bit-320.49-whql-driver.html
http://www.filehippo.com/download_nvidia_forceware_vista/


2) http://setiathome.berkeley.edu/show_host_detail.php?hostid=6716264

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:
http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm

! 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)


P.S.
You didn't read the docs:
In:
...\BOINC\projects\setiathome.berkeley.edu\docs\

Read:
Lunatics ReadMe.txt

"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!

P.S.
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.
