hello , i have a reference sapphire 7970 ,and i have read many articles concerning overclocking this gpu most of which assure the user that a 7970 can be clocked to 1125 mhz easily with the memory overclocked to 1575 mhz on stock voltage ,however the i can only achieve 1075 mhz core clock and a memory clock of 1575 ,adding voltage doesn't solve the problem ,anything beyond 1075 will cause artifacts in furmark ,temps are within normal range so thats ruled out,question is , is it safe to say that the psu is the problem here ? specs are :
Motherboard : Intel DH67BG
CPU: i5-3570 non k
GPU: reference sapphire 7970
PSU: thermaltake 600 W litepower series (double +12 v railings i believe)
