i experimenting with the memory anbd if i pull out memory it works , seems this motherbord  don't suppoort 8 gyg ram  , on lot of forums they mention this mb can hold 8 gyg of ram but seemsq this is'nt true

[Christophetje69bis]

it is solved with pull out 2 bars of  RAM  , using 4 gyg instead of 8 gyg , i think this MB Evega 790i ultra sli has problems booting with 8 gyg Ram
many thanks for tour support !
