I really wished I could help but the one I bought already had its bios updated. Do check out on YouTube or visit the nearest PC store near your place. I am sure they will be able to flash the latest bios on the mobo. Anyways, if I am not mistaken, it is done via a USB stick (thumbdrive).
Thank you so much for the positive feedback!
Good choice on the graphics card, the 750ti is a rather old card so the rx 470 is definitely a good choice given its performance and value!
Thank you for the positive feedback!
It performs surprisingly well but of course, it depends on the games you play. For me, I only play CS:GO and other non-gpu intensive games and I have to say, it is able to provide me an enjoyable 1080p gaming experience!
Awesome built! Planning to get this mobo but a i5 6500 instead.
