    SLI Problem

    Post by SheepMeister on Thu Dec 23, 2010 11:11 am

    I´m using 2 Nvidia GTX 460 in SLI and it seems as if the FAH Tracker uses the same WU for each GPU. When the WU is finished i get the following error on GPU0:

    [16:54:13] Working on 2 PEPTIDE (1-42)
    [16:54:13] Client config found, loading data.

    When I start GPU 0 again i get the following:

    So the GPUs basically do the same work. The client Stats for GPU 0 won´t show any finished WU. Any idea for that Problem?

    AFAIK SLI has no effect on the F@H GPU3 Beta client, since it's not used. My 2 GTX460s are running fine as GPU0 and GPU1.

    It looks like you may have old work in queue which may be causing the problem.

    I would nuke the whole Tracker folder and do a fresh install with the current version (3.44). Tracker makes it too easy... ;>

    You didn't post quite enough of your logs to see what the client was doing on startup, which may be relative since the client crashed!

    Post back what you find.
