Specs are as follows:
i5 6600K @4400
AsRock Extreme 4 Motherboard
16 Gigs of G.Skill TridentZ 3000Mhz
2x Sapphire Reference Rx 480 8G in Crossfire
Samsung 840 EVO 500g SSD
Corsair RM1000i PSU
I want to undervolt and overclock the Rx480's. I am able to adjust the voltage and frequency of the primary card with no problem (P-State 3 to 7) but I am only able to adjust the voltage and frequency of the 2nd card at P-States 6-7 in terms of frequency and voltage.
Do I only adjust the values on the primary card?
Thanks in advance.
You'll need to adjust both.
