gtx 680 Could not get an assignment

har lite problem med folding
allt har fungerat en bra tag, jag har tom installerad senaste beta drivrutiner från nvidia och allt var ok, men för två dagar sedan mina två gtx 680 blev klara med jobbet och sen stannade det på download
om man kollar log så stor det att de hittar inga jobb för mig
försökte hitta ngt info men hittar inget, jag hittade dock att man kan köra två klient per gpu så jag har typ 4st gpu klient trots bara två grafikkort
de visas som gf104 (gtx680) och gf114(gtx 680)
allt har fungerat innan som gf104 och det var runt 18-20k ppd per grafikkort
nu fick jag åtminstone 10k ppd från de gf114
här är en del av loggen

är det möjlig att WU är slut? eller det är ngt annat fel
har provat med client-type advanced eller helt utan det men ingenting hjälper, allt har fungerat med beta förr

///EDIT

ok, hittade lite mer info, folding fungerar inte längre på gf104 dvs gtx 680 som förr, alltså den är som unsupported numera men man har gf114som har support och gtx 680 identifieras som den också, dvs varje kort syns som två, visa säger att det måste ha varit ngt bug men det verkar så att de gick runt problemet med gtx 680 tills det blir fullständig support

alltså om man hade gamla gpu.txt som visade gf104 (gtx 680) på en vitlista så är den fel och nu finns det nyare som sätter den på svartlista men man får köra på grafikkort som gf114 som skulle vara gtx 560 om jag säger rätt men för mig visar den fortfarande som gtx 680, hur som helst det fungerar och förhoppningsvis får vi ordentlig stöd för gtx 680/670 inom kort
