only thing that doesnt work in that lot you mention is the temp on slave, all the rest works for both cards. i dont ever use ccc anyway, its closed in the msconfig startup and i just use ABCCC2 has no temp, activity, fan speed or core/mem frequencies for the slave card. Also lacks manual fan speed control, with 10.12a it would allow it for about 10 seconds then go back to auto.
i guess sometimes its hit n miss as to their systems stability when installed
im happy, i do want them to change the xfire enabled logo tho ( im fussy like that )
