Just to add

Reporting a bug in X570 Aorus Master BIOS F5L (and likely future versions):

If you set memory multiplier to 36x or higher on the main Tweak page, the VDDG voltage will change from "Auto" to "Manual / 1.05v" in AMD CBS menu. No matter how many times you change it, it reverts. My chip is unstable with that much voltage through VDDG at my current settings, and the workaround is to keep it set to "manual" and put the correct standard VDDG voltage of 950mv.

Same here, was wondering how motherboard itself managed to change this to such a specific value :D

Q Flash works just fine with CPU installed. I have used myself with CPU. Just make sure you hold the button down long enough for it to start blinking red.
Sweet! Just be sure not to make any changes with RM from now on

And spoke too soon again, while I did manage to flash it at lunchtime yesterday, and I managed to get into Windows and run a few benchmarks and all seemed good, I went to turn it on again that evening and it's dead again, and I can'r get it to boot even after re-flashing the Bios.
This issue is clearly intermittent, when it's working it appears to usually work, leaving it shutdown for any period seems to put it back in the bad state.
Maybe it's flashing a bad BIOS from the backup when it cold starts.

Of course I had just cancelled the RMA after getting the approval....UGH!
Time to start the process again.

We bought some noctua's and can reproduce this now. Working on a fix.



What specifically are you changing? I just tried enable XMP -> save & exit (F10) -> booted to windows.



Still working on this. Root cause seems to be linked to the GPU being used. We have systems we can reproduce it on, and systems that work fine. Need more time to test / identify root cause.
VEGA 56 with my master and dual rank B die at 3800mhz fast 1usmus preset / FCLK 1900mhz, boot takes under 10s to BIOS with CSM off and secure boot on, with the RAM on XMP it's pretty much instant, the board post code and debug LEDs flash ridiculously fast for 3~5s and I'm loading windows.

Overall I'm happy with the board, just wish AMD would fix boost, if you guys ever get a BETA bios with new AGESA I volunteer as a tribute.

@GBT-MatthewH Following up on our convo yesterday, are you sure that what happens during bios failure is that the backup bios is flashed over the primary - NOT that it simply switches to the other bios? I reflashed the bios to the latest version - and it works more or less - but now every time I cold boot, the DRAM debug light is on for like 40 seconds, almost like it's trying to boot from my other bios with bad settings and then giving up and going to the new one.

if that could be the case, would taking the cmos battery out clear the settings on both bioses?

Other than the odd MSI Creation result it isn't that bad.


Keep in mind 4455 MHz is basically equivalent to 99MHz BCLK instead of 100MHz.


Also if people want to buy the Aorus Elite that seems to have went out of stock Newegg is carrying Aorus Elite WIFI now for $10 more and Amazon is supposed to get them August 29th

Do you know why it seems to be a problem on the "cheaper boards" this generation?
Every time I am on default settings, I never see 100 MHz any time.
It is always 99.8 MHz.
Since I can only change the clock in 1 steps instead of 0.1 I am running my setup with 101 MHz but it takes a longer time to boot doing so. (I guess the increased clock of the RAM forces a new memory training every time.)

Updated 1st page with latest BETA BIOS. No change log, just the newest files I saw on the server. As always if I messed up a link just @me and I will fix.

@GBT-MatthewH
Do you have or can you put up on that page (or link to) a change log for the beta BIOSs ? That way I can decided if I should flash now or wait for those changes in a BIOS Full / RTM release.

I don't have the board in front of me, so I can't test for you, and unfortunatley the board doesn't have the BIOS LED to tell which it is booting off of - however Q Flash+ (the button on the board) will re-flash main BIOS if that's the concern.

That sucks. Usually on AM4 if the board fails to post it will revert the bios settings to default (2133 mem, etc) it will not flash the bios on its own.

I had an issue with the newer bios that has Agesa 1.0.0.3 ABB. All seemed well after flash but would not post after being shut down over night. I used Q flash to put F5j back on on haven't had issues since.

You probably already tried this but hit the clear cmos button and then q flash an older bios. Only other thing that causes intermittent issues would be a faulty PSU.

Also on my brothers build I gave him a Toshiba RD 400 nvme drive that was taking a dump. The machine would not even post to clean install Windows even when it wasn't the primary boot drive. Took the drive out and all was normal again. Just a thought

Change logs don't really exist for BETA BIOS. They are more of the "latest build" from our R&D team. There are 2 key problems with a change log -

#1. Since we haven't fully tested the BIOS its hard to say "This is fixed". Actually that's why I post stuff here. I generally say "X should be fixed" and see if you guys get the same results.

It could just be lack of an external BCLK chip. That's usually omitted on lower end boards. I'd expect the X570 Aorus Master to have it and for the other vendors probably X570 ROG Hero , Asrock Taichi, and MSI Ace. The STRIX line in ASUS doesn't even have VRM temperature sensors on the boards under the STRIX name ... :rolleyes:


Keep in mind Ryzen polls every 1 ms (1000 times a second).

Do I need to take the CPU&ram out in order to do that?
no you do not. The manual is wrong I have used the Q flash back with every thing installed and it works as intended.

It would be pretty useless if you had to rip you rig apart to flash especially if using the stock AM4 cooler which is notorious for ripping the CPU out of the locked socked since you would not be able to run a stress test to warm up the CPU prior to removal.

  • EX fan after resume. In F5N (for Master) we thought we fixed it, and we did for 90% of people. But there still seems to be an issue with Noctua fans, so its not really 'fixed'. If I post "Its fixed" and someone has a problem its often followed shortly by "This company sucks, they can't fix stuff, its still broken for me, what a joke" etc... So how would you categorize this or call it fixed at some point?

  • Kind of off topic but often when you try and give information/fix issues/respond in general people will use it as a platform to be negative/take out their frustration. Its the nature of the internet, but let's not be naive - It can, does, and will make companies/reps hesitant to say anything. I deal with it because whatever, but don't think were robots on the other side of the screen. The idea that you have to scream and shout to get your voice heard (ie squeeky wheel theory) is the wrong approach.

  • If you think the various reps on any public facing forum do it strictly for a paycheck you are wrong . I can guarantee most higher ups don't troll reddit/forums looking for their employees being helpful. Trust me when I say that being active on forums creates more work, not less, and there is no bonus for # of posts ;-) We do it because we are enthusiasts too and genuinely want to help the community and our companies put out the best products. Anyways back on topic...

#2. Its hard to keep a log since the version numbers are all split. The fan fix may have been on F5N for master, but F5L for another board. Etc. It gets confusing even for people monitoring all the time.

All that being said if you want to create a google sheet maybe that should be the best way? I'm not opposed to the idea, I just see it as becoming unmanageable easily.

Which board did you try it on?

When it switched to the backup bios for the first time (with the first bios version), did you notice high post time? Ever since my backup bios activated yesterday it's taking like 40 seconds for the DRAM debug light to turn off. It only happens on cold boots though. I'm worried maybe it's trying to boot my primary bios now and it's failing, and now if I happen to use bad settings with my backup bios as well then I'm screwed.

When you say your profiles were gone when it switched to a backup bios that was once your primary, you mean all settings are stock right?
IIRC I didn't notice any change in boot time. After the switch, it was reset, yes, but the profiles I created on the BIOS before were still there. I suspect it actually switches to the other BIOS, instead of reflashing the main one.
