Asus usa/canada said that i should ask amd for original vbios and amd said i should ask asus . Asus poland sent me the "updated vbios" alone which i can find in package on website anyways . All i can tell to close this topic is that i tested all vbios for my card and verified from techpowerup is only 1 and it performs so much better than any other.
If you ever doubt what vbios works best for your card ( strix-470-O8G-gaming) i leave it here.
8 GB GDDR5, 1250 MHz GPU, 1650 MHz Memory

Asus destroyed this card with their "updated vbios" either never change ur card vbios or use the "verified" one i linked as its the only one tested by that performs head and shoulders above the rest. End of topic.
