Bios Flashback

Ability to update the BIOS without requiring a CPU and RAM installed on the motherboard. This advanced feature is intended for experienced users and is useful for supporting newer processors on older motherboards. Please refer to the manufacturer's instructions for the process, as it may vary between manufacturers.

For example, if you want to install a Ryzen 5000 series processor on a chipset that only supports it after a BIOS upgrade, BIOS Flashback can be used without having an older processor on the motherboard.

    Verified purchase

    Finally, Greece and not from China with Chinese software and BIOS.
    The old ones remember the glorious days of sapphire mobos, the new ones should learn.
    I bought it with a 7800x3D (since the tray costs €305) and with 2x2TB Kingston SSD pcie4.0 and Arctic freezer 36A white ARGB, it is the best and most economical high-end combo (for September 2025).

    We all know the specs (wifi6, 12+2+2 power phases, usbs etc etc). Let's go for something more nerdy and techy.

    Drivers: Unfortunately, there is no way to download all the drivers like asus/asrock/gigabyte/msi (e.g. I had a B550 AX V2 and through GCC I had everything from bios to audio/cpu/gpu/lan/wlan drivers). Here you go to the site, download and install them one by one.

    For ARGB control (here you will get frustrated) you have to download TriXX which comes as a "portable app" with just an overview of the motherboard and GPU (if sapphire). As soon as you try to do a normal installation, it tells you that you don't have access to the temp/folder so you have to go to CMD-%TEMP% to find all TRIXX related files-delete and re-download 10.0.0 for it to work. After you install it, sometimes it gives you ARGB/CASE fan control, sometimes not... I found a workaround with Signal RGB and CaseFan Controller so I set everything up ok. I think now that they've entered AM5, in about 6 months everything will be perfect, but a new - impatient user - or someone who doesn't know will struggle. Also, it doesn't have auto PBO+CURVE optimizer. You have to do it manually or via Ryzen utility?

    Finally, let's say that if you get past these issues, it's the only €150+/- motherboard that supports 12+2+2 phases with 55A, making even the 9950X3D functionally excellent without thermal throttle at a good price. All heavy metal, much better than other solutions at the same price.

    2 stars because while everything works NOT just like clockwork but EXCELLENTLY, the lack of ease in drivers/utilities is very reminiscent of the 90s/00s...! If they fix it in general, I think other companies will easily start to tremble.

    Update 8/10/2025
    Good motherboard but annoying fan and utilities control... It tires me, I will probably change it... It requires a lot of patience...! Also, what's up, was I lucky to get the motherboard for €147.5? Suddenly the motherboard starts at €188.28... Guys, while it's fantastic and I'm not 100% sure if I want to leave it for another, at 150> it was worth it, at 275< not even close, go for a Gigabyte Aorus/Eagle x870 with wifi and all... Or an MPG MSI which at €300 is a masterpiece in everything!
