I had this error pop up today in the log

If it's OC'd, it could be a stability issue where a number was mis-calculated. Even if you believe its stable, it may not be after being on for an extended period of time or such. I suggest running prime95 for a good long while to test for stability.
yea im albe to run orthos on both cores for quite a long time last time i ran it was for 48hours.
but today i also got the same error on a different box that everything is on stock settings.
good thing is it errored out about 2% into the WU .i copied the error but its at work. ill try to paste it in here if i can later on
any new patches/updates perhaps that you've installed? It seems very random, and some of the same proteins are running on boxes here with no problems. You installed IE7 or something perhaps?
