Zotac 560 Ti 448 problems

I just installed a new video card. I replaced my gts8400 with this new card (Wow what a jump). It seemed to be processing WUs fine (ie errored out on all current cuda and cuda23 WUs and downloaded new cudafermi unit and finished some of them fine).

But yesterday I started getting these types of messages:12/21/2011 8:15:19 AM | SETI@home | Aborting task 22no11ac.25555.13295.7.10.107_0: exceeded elapsed time limit 5515.42 (1706055.46G/309.30G)

As of 7AM this had happened 14 times in a row without a successfull fermi WU completion. Watching from the BOINC manager I see the elapsed time progressing and the remaining time decressing but the % complete remains @ 0% unit the WU aborts.

Firestorm the Zotac moniter show the temp as 33 and windows task manager show no cpu activity for the cuda_fermi task.

Do I have bad WUs a bad app or do I need to change something?

Rebooting my system has fixed the problem. I had been toying with the core/shader/memoery/fan settings and may have 'tanked' the card.

I am using the video output from the MB and not the card, MB's video processor has been disabled from seti processing might as well use it for something :)

Given that my machine continued to work and I had a working display how do I go about setting the controls for core/shader/memory clocks and onboard fan? Is the fact that my temp went to 33C not the 57C that is @ now while under load my best indicator?
