Updating Crash Free bios safe?

[Miksu11]

Hi, I got this mobo a months ago and it says that it's completely safe to update bios. So if there's powerloss or the update crashes, it is safe to update still? I need to patch the bios against meltdown and spectre.

So I don't need to get a UPS.

You should update to bios version 1203 to fix the spectre problem. (Can only be fixed by an BIOS update.)
Meltdown is fixed by keeping your OS up to date.

The part about powerloss etc is always the risk when it comes to updating the bios.
If you live in a contry / area where powerloss is "normal" I would get an UPS to be on the safe side. (But that is me.)

But if the powerloss happens suddenly (even it is unlikely), does that board have safeguards against it? That was the main question. It advertises that you can recover it even if it happens

It has a dual bios so if one fails you are safe.

Where did you find that it has dual bios? can't seem to find anything about it.

All asus motherboard has it. Atleast the mid/high ends have.

Ok I'll check it just to be safe by opening the case, thanks!

It doesn't have 2 BIOS chips; it has ASUS CrashFree BIOS 3. You can read on it here: https://www.asus.com/support/FAQ/1012219/

You are correct. Seems like it gets more and more normal to use the "CrashFree" or "FlashBack" instead of dual bios.
I stand corrected.

So updating bios without UPS is pretty safe?(if it can't recover, its covered by warranty?)

Even if there wasn't power loss, what if something goes wrong during the update?

Sorry for alot of questions, never have flashed bios, only on my laptop

Do it from the BIOS when the risk of a power failure is low. It isn't time to do it when there's a major storm, etc.
