Grrrrrrr arghhh!
So FAH shows slot 0 as my 670 and slot 1 as my Titan (doesn't really matter which slot # it assigns). I used GPU-Z to inspect my cards and it shows that the Titan is performance capped because of temperature limit. Makes sense, that's what it's supposed to do. So I turned off in F@H what was labelled as the 670 to get a feel for "will it fold faster if the 670 temp isn't there". Went back to GPU-Z and it shows the Titan at 0% GPU load and the 670 at 99%! I also looked in Speccy (another program) and it too showed the 670 going and the Titan doing nothing.
So basically they appear to be labeled backwards in the F@H client for some reason. I even did a complete removal of the F@H client but nope... they're still backwards.
It doesn't hurt anything probably, unless at some point either card is supposed to get a specific type of WU that the other can't process. Just odd they're labeled backwards.
Whatever... I'm just gonna let them fold. I got passed costabunny and I can't let her catch up again.
