New UEFI BIOS updates for ASUS AMD motherboards – W10 AMD – A520, B550, X570 *For applicable boards, this UEFI includes the latest AGESA V2 PI NON-BETA This build also introduces support for SAM with Ryzen 3000 series CPUs and RADEON RX 6000 graphics cards.

UEFI BIOS update list noted below – A total of 10 boards with a UEFI BIOS update.

W10 is shorthand for the workweek; these updates were released between March 5th-12th.

Why if my motherboard is not listed?

If you are looking for your motherboard/model, I would suggest going to

and checking if it has been updated recently. I post updates weekly. UEFI's are released in waves; because of this, it can take an entire series weeks or months to see the "same" update if it includes items like CPU firmware. Furthermore, keep in mind that not all updates apply to all models. Due to inherent design differences and specification and feature variation, an update may only apply to a specific model.

How can I be notified about releases?

You can also follow me for notifications when updates are released/posted. I am also the admin for our PCDIY Facebook Group where I post updates and other ASUS centric product news

How long after a board is produced will UEFI updates be released?

After a year, a motherboard reaches a certain maturity level and will see fewer updates. If you feel you have an issue dependent on a UEFI release, please submit a support ticket. In some cases, some boards can see updates for more than 24 months+

I want to update but am not sure how to update the UEFI "BIOS"?

If you want guidance on how to flash/update your UEFI BIOS, please watch the video linked below.

How to flash/update your UEFI "BIOS" on ASUS motherboards

Should I update the UEFI if my system is stable and running without issue?

If your system is running without issue, especially if overclocked in any way ( including DRAM ), it is advised you stay on the build/release you are on. Changes to underlying auto rules and other operating parameters can change the OC experience and require you to retune a previously stable OC value. This does not mean the UEFI is not a functioning release but that changes in the underlying code base need to be accounted for when tuning a system. As many of these values are in low level or specific operating parameters, it is best to retune from F5 UEFI defaults after re-run stability test at UEFI defaults.

What if the UEFI BIOS listed is a BETA? Should I update?

BETA UEFI releases are for enthusiasts who want access to the latest features, functions, microcode enhancements, and overall UEFI improvements. As they are not officially supported, they are not recommended for day-to-day / long-term use. Users who plan to use their system in this capacity and want to ensure the best interoperability/compatibility and stability and performance should wait for a formal release.

Will a UEFI Update improve the performance of my system?

A UEFI update can include CPU microcode and other performance tuning adjustment enhancements for the UEFI that can influence/increase performance. With this noted, it is generally minimal. As always, performance analysis/comparisons should be made at stock-to-stock values. This means loading F5 on both releases and comparing your application/benchmark scores. OC-related comparisons may require retuning before testing as changes to underlying auto rules can invalidate prior scores even with similar settings.

Not every user should update/flash their UEFI BIOS. I stress this again; if you are running without issue(s), you are advised to stay on the release you are running.

Notes to consider -

* When flashing, please perform the update process at F5 UEFI defaults. Do NOT flash with an overclocked system/profile.

I recommend updating the UEFI BIOS on your motherboard for new PC builds. Updating the UEFI ensures the best interoperability, compatibility, and performance. If you are building a PC and have not yet installed the OS, I would recommend updating the UEFI. Keep in mind flashing/updating the UEFI will reset all defined parameters/settings and operating profiles. You will not be able to restore defined values using a UEFI Profile as profiles are not interoperable between builds. It is advised you note or screenshot (F12) your values before flashing if they are complex. Upon completing a flash, I would recommend you load UEFI defaults after the fact and complete a full reboot and shutdown before re-entering your initial values. Keep in mind you may need to retune these values under a new UEFI. When you update the UEFI and re-load UEFI defaults depending on your originally defined CSM/UEFI device parameters, you may experience BOOT issues. Depending on prior settings, you may need to enable or disable CSM to restore BOOT functionality. Be advised that in some cases, a rollback to a prior UEFI is not possible. While not always necessary, some UEFI updates may require a clearing of the CMOS. You can either clear the CMOS via the CLR CMOS button if your motherboard has this feature/function, or you can also CLR CMOS by removing the onboard CMOS battery for at least a few minutes. You can locate the CLR CMOS jumper on the motherboard and short the pins. In some cases, you may not be able to jump from an older UEFI release to a much newer release. You may need to "step" update; this will mean upgrading incrementally to a slightly newer build first. In most situations, this is not required.

I also recommend you backup your system before any flash/update and always advise flash/update become executed from a fresh loading (F5) of UEFI defaults.

UEFI with AGESA (USB fixes) is the one worth celebating when it arrives.

If there was ever a bios update we can't afford to wait weeks or months to be delivered to a large number of boards, that will be the one. I hope ASUS is prepared.

ID: gqtpx9r

From what I've seen ASUS often delivers bios updates before other companies deliver a first beta. I think they'll do ok

ID: gqq1vhg

True - but it's clear that AMD just made an announcement about that version. has been in the works for 2-3 weeks at this point.

Will Crosshair VI Hero/Extreme get a beta bios atleast?

ID: gqsqw7c

No...I would love to have it as I have a C6E but Asus won't update it. While I love the board it's the last Asus board I'll be buying. When it's time to move on I'll go with ASRock.

Crosshair VI Asus?

The download is there for the Wifi version too:

Check the "Bios & Firmware" tab - the "driver and tools" tab has bioses but the bios tab is often more up to date. Eg. the Driver & Tools tab only has the 3405 BIOS as latest.

I don't see it listed, but the X570 i Gaming also got updated to V3602

Is this correct, or is it supposed some other board?
The pages for all the TUF B550M boards don't have anything newer than 1804.

The board is about to get release soon. Product page is up but still looked

anyone tried it?

Flashed on dark hero 2 days ago. No issues to report. Seeing better bench mark numbers.

ID: gqrbb0e

Similar but needed to change some settings again. For example from llc auto to lvl 3. But same temperaturs as before.

ID: gqtq0sg

Same. About 5% increase.

ID: gqrrjem

Flashed version 3302 on my Dark Hero yesterday. Didn't dial a new dynamic overclock + PBO, I just used my stable settings from 3204 to check for stability before I see if I can make any improvement. So far so good.

B550M-A Prime no update, me sad 🙁

15 : Anonymous2021/03/12 22:39 ID: gqqp90z

I see that one of the updates is "Fix the L3 cache performance in AIDA64" - is this just fixing what AIDA64 is reporting, or is there actually an L3 cache performance improvement? (I'm not personally aware of other programs that report L3 cache performance)

ID: gqqycyj

Supposedly, it just fixes the reporting in that one app.

16 : Anonymous2021/03/12 23:36 ID: gqqvkz6

ASUS Prime X570-Pro / Ryzen 7 5800x

Modest improvement in AIDA regarding L3 Cache, but I am unsure if this translates to anything real world. Cinebench r20 and r23 show similar results before and after (within margin of error)

We'll see how stable it is, now awaiting AGESA 1202 ...

ID: gqr0ia1

This fixes the issue reporting the data in the app, not that there were something wrong with the processor

Well done Asus.

18 : Anonymous2021/03/13 04:17 ID: gqroazt

I just updated to the new bios on my MSI b550 A-pro. (Not Asus, I know) The only difference I've noticed is that my 3600x only boosts to 4.37 to 4.39, after boosting to near 4.6 on the previous. No real world difference, and seems stable so far.

19 : Anonymous2021/03/13 08:10 ID: gqs5dsc

Will this update fix the dreaded 8d boot error once and for all? Anyone can verify? I'm on VIII Hero (Wifi) with 3700x and 32gb of 3600mhz Corsair RGB pro.

Why is the B550-XE not in the first batch to be updated?

Oh sweet summer child. lazy? No, the longer they wait, the more people just give up and buy a newer board. That’s a strategy, not laziness.
