r/overclocking on Reddit: PSA BIOS 3904 for Asus Crosshair VIII Dark Hero is bugged (AGESA 1.2.0.5). Voltage stuck at 1.425v. 3801 (AGESA 1.2.0.4 Patch C) is fine.
December 23, 2021 -

Just wanted to give everyone a heads up. This bios is bugged. Confirmed with some other users and my 5900x and 5950x. Use 3801 until it’s either fixed or the next AGESA releases.

Edit - 1.2.0.3 patch C is fine, not 1.2.0.4.

Edit 2 - The new beta bios 4001 and AGESA 1.2.0.6 fixes the voltage issue when using EDC 200 or over. It seems to fix all issues that were related to AGESA 1.2.0.5 bugs! Never mind, voltage is still stuck at 1.425v with edc at over 140. This is bs. So feel free to grab it if your on an Asus Hero motherboard from this link over at overclock.net

r/ASUSROG on Reddit: Dark Hero x570 bios 3801 TPM problem
September 18, 2021 -

The issue: I switch the TPM setting from "Firmware" to "Discrete" (which should disable it since I don't have a TPM card), press F10 to save and quit, but when I enter bios again, the setting's back to "Firmware".

Some info that might prove useful/relevant:
I've enabled TPM (going from "Discrete" to "Firmware") when I was on 3601 bios, as I wanted to try Win11. After a few weeks went back to 10 by doing clean OS install and shortly after I've updated the bios from 3601 to 3801.

Everything works great with one exception: I'm getting some random stuttering/freezes in which the sound gets distorted as in a complete system freeze, but it lasts for about a second and the mouse cursor seems a bit sluggish. A few per day.

This is the reason I want to turn off TPM (but can't apparently) - to try to see if it's the cause if these annoying freezes.

Anyone else experiences any of these problems (bios setting and stuttering in windows)?

system:
PSU Corsair AX760i; MB Dark Hero X570; cpu Ryzen 9 5950X; 128gb RAM Crucial 3600Mhz; gtx 1080Ti; SSD 1Tb 980 Pro for OS (Win 10, version 21H1). Currently no OC, everything on default in bios.

If are still experiencing USB issues please feedback via the link below -
https://www.amd.com/en/support/kb/faq/amdbrt

Why is my motherboard not listed?

If you are looking for your motherboard/model I would suggest going to https://www.asus.com/us/support/ and checking if it has been updated recently. I post updates on a weekly basis. 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 are applicable to all models. Due to inherent design differences as well as specification and feature variation an update may only be applicable to a specific model.

How can I be notified about releases?

If you want to be kept in the loop, 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 https://www.facebook.com/groups/ASUSPCDIY

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

Keep in mind that generally after a year a motherboard reaches a certain maturity level and as such will see fewer updates. If you feel you have an issue that is 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.

https://www.youtube.com/watch?v=scK8AP8ZACc

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 full UEFI defaults after you have 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, and 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, as well as performance, should wait for a formal release.

Will a UEFI "BIOS" update improve the performance of my system?

A UEFI update can include CPU microcode as well as 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 done at stock-to-stock values. This means loading F5 on both releases and comparing your application/benchmark scores. OC-related comparisons may require retuning prior to testing as changes to underlying auto rules can invalidate prior scores even if 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 full UEFI defaults. Do NOT flash with an overclocked system/profile.

1.I recommend updating the UEFI BIOS on your motherboard for new PC builds. This helps to ensure the best interoperability, compatibility, and performance. If you are building a PC and have not yet installed the OS, I would recommend you update the UEFI.

2.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 by using a UEFI Profile as profiles are not interoperable between builds. It is advised you note or screenshot (F12) your values prior to 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 prior to re-entering your prior values. Keep in mind you may need to retune these values under a new UEFI.

3.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.

4.Be advised that in some cases a rollback to a prior UEFI is not possible. This generally is the case when there is an update that includes CPU microcode (such as an AMD AEGSA or Intel ME). This means you may not be able to “flashback” to a prior release.

5.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 also attempt to locate the CLR CMOS jumper on the motherboard and short the pins.

6.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 prior to going to the most recent build/release. In most situations this not required.

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

The board model/name is on the right-hand side and the version number is on the left-hand side. To download the UEFI BIOS please go to https://www.asus.com/support/

1.2.0.2 boards are -

Boards with the 1.2.0.2 release if your board is not listed as noted in post notes please be patient as more updates are coming.

Should I update bios? I’m getting WHEA Logger errors with event ID 1 and 18. Is bios a culprit? I just downloaded and installed chipset drivers which could have been the problem. I have a 5800x cpu. My ram is now set to default. As that was potentially a problem. But the issue continued. So now I have just downloaded the chipset drivers. No errors yet but I just did this an hour ago. But I’m curious if bios could potentially be the problem? Looks like 4702 is available. Any advice will be appreciated

June 22, 2023 -

So I have the Dark Hero VIII and I've never updated my bios. Never had problems with my set up and just got nervous about bios updates in general. Recently I installed another SSD to replace a 3 month old SSD that failed. After adding the first or the second SSD I had problems booting up. It was stuck in a bootloop, I clicked the clear CMOS button and lost my settings for my memory (link) overclock that never gave me problems (Originally settings are beyond me; maybe a preset was selected but whatever I did in bios two years ago got me from the 2666 to 3200Mhz). I tried to replicate what gets my RAM to 3200MHz using a D.O.C.P Profile. I think it overclocked my CPU (5900x) too, obviously I have no idea what I'm talking about and I just want this expensive POS to turn on and let me make sad music on Ableton. My boot up time is taking a heck of a lot longer (Monitor stays black for a while then all of a sudden the fans roar and I'm at the windows login), was working yesterday with the settings applied and when I tried turning it on today it got stuck in the loop. If I reset bios settings (default 2666Mhz, no fan optimization, CPU base clock) it boots up no trouble.

What I'm wondering is should I update my BIOS as I've gathered that different bios include different XMP Profiles? I've tried to learn how to manually overclock and I have had no success and I am in enough credit card debt (because of this build, 2 years ago) where I can't quickly replace my fried CPU or Mobo.

I am tired and frustrated and have been dealing with this for a few weeks now and this inconstancy of will I be able to just make music in my enclosure when the girlfriend goes up to sleep is draining paired with feelings of inadequacy when coming to a subreddit of knowledgeable lot and like here's my "overclockers mobo", I don't know how to overclock or get the most of my build let alone get some dram to run at the advertised speed.

Appreciate you all. Thanks.
