Can anyone test if EDC bug still works on F20a?

EDC=10 works for X570 AORUS XTREME F20a AGESA ComboAM4v2PI 1.0.0.2, we also have unlocked AMD_CBS menu, all the settings you want and more to tinker with.

Already done, bub.

I can confirm it works. But not as good as before for me.
Very swinging scores in CPU-z, very stable but low scores in CB20.

did u check your watt on cpu package, i cant seem to get past 145 w no matter the settings, might be why, clocks are high but yea i only get 145w power draw so thats why my scors are same as defult.

F20A seems okay for me, but I've yet to run full memory/stress testing to validate the configuration yet. Cinebench score as identical to F12g (considering there is so much variance run to run getting the exact same score is pretty crazy). Slight uptick in memory Latency as reported by Aida64 (64.1 vs 64.4) but that doesn't necessarily mean anything.

As someone else mentioned SVM mode seems to be enabled even if it is disabled in BIOS. Virtualization software is running without issue even with the setting disabled in BIOS so seems to be broken.

 

[Nighthog]

Yeah can confirm Virtualization is default enabled and can't be disabled.

PPT seems stuck @ default even if configured higher with PBO. (AVX2)
There are a few extra settings in BIOS in regard to power, cTDP & PPLC... settings about fused on-package values. These didn't really do anything before maybe they work as intended now?
You need to use Manual settings rather than AUTO fused package values? I always thought these were for the fused values to be overridden but never found that they actually did anything when set.

PPLC = Package Power Limit Control *PPT will be used as the ASIC power limit*
cTDP Control = *will be used for RC Thermal model only*

EDIT: Nope did nothing setting Package Power Limit higher. (It overrides your PBO PPT value)

Don't know cause my PPT is configured at 135.
But I found out for some weird reason mine is limited to 115... only in the main install.
If I boot from the USB with the benchmarking Windows it goes up to 135 with no problems.
Maybe it's the same issue as yours?
No idea what could do something like this...

Here's my first feedback about F20a... TLDR; I'm probably going back to F12a soon

The good:

• Unlocked settings in AMD CBS
• PMU pattern bits can be now configured manually
• Better memory compatibility (can run CL16 with GDM Disabled now)
• ProcODT at 60 with XMP profile fixed
• Can now run VDDP/VDDG at 1000/1050
• Better UI graphics...

The bad:

• IMC is broken; memory bandwidth (Sandra) at 3800 MHz is much lower than F12a, almost same as when configured at IF 1800/3600 MHz.
• Memory latency is different (Sandra); about 75% worse (2-5 ns), rest better (2ns)
• Almost all voltages, LLC settings behave differently
• Worse scores in benchmark, from a tiny bit to quite considerably, probably related to memory issues
• Weird stalls under the main Windows install, feels much slower
• Fixed SOC Voltage now is a problem, up to reboots during CB20 MT, have to keep in Auto
• VDDP/VDDG at 900/950 is messy now, much lower scores

You nailed it!! was going crazy over CB20 reboots until I set the SOC voltage to Auto!

Is smart fan working for anyone? I can't access the menu in the bios.

F20a

Virtualization is default enabled and can't be disabled.

Annoying... probably source of some other issues like swinging scores.

No problem with it. Maybe worth trying flashing from FreeDOS with DMI clear.

F20a

Virtualization is default enabled and can't be disabled.

Indeed, another reason for the low scores with PBO. They are piling up...

It's very weird... I almost got back full memory bandwidth but I don't know how.
I've benched IF 950/3800 and got almost full bandwidth.
Set back to IF 1900/3800 and instead of the crippled results as before got the same almost full.

I've been able to set VDDP/VDDG 900/1000, looked better but now I have crackling audio and USB drops. :thumbsdow

A couple notes here.

First, you should always “Load Optimized Defaults”, save and exit, flash the BIOS, and then ”Load Optimized Defaults” again when flashing a BIOS for any motherboard on any architecture. Yes it is possible to dirty flash, but it can create problems, some hidden. A particularly nasty scenario is a case where functionality for an item is present, but the UI option is removed. I have had this happen on both AMD and Intel systems. The only way to really fix things at that point is to open up the case and short the pins. On some boards I even had to remove the battery.

Second, Ryzen Master will launch with SVM enabled, however it won’t launch with Hyper-V enabled.

idk then. i'm still on F12f official and don't have hyper-v enabled. svm was the only setting i toggled and ryzen master complained when SVM was on and didn't when SVM was off

 

[ManniX-ITA]

Seems I got rid of the audio crackling enabling LN2, let's see if it's stable.
Kinda pathetic Gigabyte released this BIOS as official straight away, don't think went through even a basic sanity check.
It's already the 2nd time I found the clock half an hour in advance.
Don't be surprised if you have troubles with authentications, software doing bizarre things, etc; check the clock.

Certain software enables Windows virtualization at boot. This is what kills Ryzen Master. Ryzen master does not care about SVM, nor should it.

In order to disable it completely you have to use bcdedit. Merely removing hyper-v doesn’t disable it.

Something like...windows sandbox? I had SVM enabled so I could run sandbox as needed, mainly.

Probably.

On a related note, I just got done dealing with a bootloop situation where the BIOS kept resetting to defaults. It eventually worked itself out after I flipped the switch on the PSU and then pushed the power button to discharge power from the system. Overall this new BIOS is a step in the right direction, but it has some bugs.

Hey guys, few questions for you.

1)Wondering if I should update to F20a from F11 (i'll just be using XMP @ 3600 and maybe enable PBO, nothing else.) I've been having random crashes that I haven't been able to sort (replacement CPU and new set of memory came in today, so i'm going to swap the CPU out.) Will hold off on replacing the memory for now as I have no idea what is causing the crash since I can't replicate it and they're so random.

2) How can I download F11 BIOS on my 2nd BIOS chip and the new BIOS on my 1st chip? That way if there are any issues, I can just go back to F11.

3) What's the best method for upgrading the BIOS (just download the file and run?) Any steps/precautions I need to take?

4) I'm currently using the Gigabyte chipset drivers, is it better to use the AMD drivers? If so, can I just download them over the current chipset drivers?

5) I have v1.1 of the motherboard, do I need to download the drivers/BIOS from the v1.1 page or are they the same as v1.0? I hadn't realized this when I first built my system and downloaded the v1.0 BIOS/drivers, so I don't think it's an issue, but want to make sure.


Sorry, I know I have TONS of questions, but i'm just trying to make sure I do everything right..

If this is the master, the easiest way to control BIOS flashing is just put the board into single BIOS mode and use the dip switch to select which is active/flash to whatever version you want to main/backup.

Not really a best method, some people swear by using QFlash+ (Flashback on ASUS, etc.) but I have had issues getting it to work on this board. I just end up going into the BIOS itself and using QFlash from there, easy enough.

As for drivers Gigabyte like most vendors seems to post whatever drivers they tested at the time, and generally do not keep those up to date, best to grab chipset drivers directly from AMD: https://www.amd.com/en/support/chipsets/amd-socket-am4/x570. Same for bluetooth/network/etc. from their respective vendors.

Board revision doesn't matter, since the hardware is the same from a driver perspective.

i guess the svm bug is causing the performance drops some you have.

with svm on and hyper-v running, your bclk drops by a few percent points, and so does your overall performance.
