Is it worth updating BIOS on F20A if I have a 3700X processor and Aorus Master rev.1.0 motherboard?

 

[Morph3R]

Are there any known improvements in Combo V2 for X570?

Most probably all the optimizations already done for AGESA 1.0.0.5 are recompiled in V2:

Change log for AMD AGESA 1.0.0.5:
- Rollup of 1004a, ab, abb, abba patches into a single release
- Fixed a PCIe lane configuration issue on the AMD Ryzen 3 PRO 2100GE
- Resolved an intermittent virtual memory error with Realtek onboard LAN
- Improved POST with select Micron DDR4-3200 memory ICs
- Optimized PCIe firmware to improve stability and interoperability

F20a brings about an incredible amount of extra bios options

 

[Nicked_Wicked]

F20a gives me the same scores as before with CB R20 as well as Time Spy and that’s with a higher ambient temperature so it might perform slightly better than 1.0.0.4b.

Seems the cores can go fully to sleep now with the Ryzen Balanced power profile, interesting behavior.

would you say that this helps overall temperature for ryzen?

does the bios still lag with csm off?

Voltages @ idle seem to be lower but temps seem the same. Might be observer effect but I doubt it.

Sure does, pretty annoying but other than that everything seems to work fine.

Can anyone confirm if EDC = 1 still works with this? Not gonna gimp my PBO over minor changes.

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.

Strange, HWiNFO consistently keeps saying SVM is on (green instead of red) despite being disabled in the BIOS. Toggling it on and off again does not seem to do anything while SVM on 1.0.0.4b was simply marked red in HWiNFO.

Does anyone know a method to test out if virtualization is enabled?

Edit: Task manager says enabled as well, can anyone confirm SVM still works with it being disabled in the BIOS?

Ryzen master gave me **** for having SVM enabled in bios. Can you open that?

It does open for me weirdly enough, even with SVM enabled in the BIOS, seems borked. Might do a CMOS reset later today, although it should be unnecessary because F20a already got flashed with Q-Flash+.

Thanks, looking forward to more feedback about this. Just recently upgraded to latest F12g and dont want to dial in all the settings again ._.

Only thing that i would love to achieve is 1933/3866 RAM...wouldnt boot even with LN2-mode enabled lel.

Any stress test programs I can use that will put the same amount of stress as a AAA game title? Going to play a few games today and see how things go, but when i'm not playing i'd like to put a synthetic load on.

Not that I know of off hand. As I have memory pass AIDA64 stress test but crash out playing a game. But AIDA64 is the most used synthetic stress test I've seen. Nice thing is it will stop the test if it detects an error so you can run unattended.

Doesn't help when new games launch with major bugs so you don't know if game is issue or something else so best to use older mature games

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.

I will be testing this BIOS later tonight. However, I am curious as to what the X590 chipset will bring to the table. I can't think of any way they can improve things, unless it is a reason to release a refresh of high end boards that don't suck.

EDIT: Power Reporting Deviation is better, but still not perfect. It is a tad over 94% for me when Prime95 was running. Previous BIOS revisions were as low as 72% depending on load when CPU voltage was on "Auto".

EDIT #2: Idle voltages are down by a couple hundred mV for me.

EDIT #3: Forget what I said in the previous edit, idle voltage is SIGNIFICANTLY down. I went from 970mV to 800-925 mV. My machine now idles at 80 watts (system power as measured from the wall). Also, apparently whatever improvements they made to fix compatibility with my RAM were reverted in this update, I had to drop down to DDR4-3466 for now. Okay, one last thing: My CPU cores drop as low as 0.2V. I assume this is the new sleep feature.

Okay, now I have to get to work.

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

Im on F11, and your edit #3 is working with F11 and latest amd chipset drivers. I get cpu vid minimum 0.2v. vcore minimum 0v. cpu sv12 tfn 0.85v. Then again i am applying an undervolt offset of -0.9v :h34r-smi
So maybe is not the new F20 bios?

 

[Nighthog]

I can note LN2 mode no longer allows me to do 1933FCLK with F20a like F12f allowed me to do.

I get stuck on [07] when it would continue along in F12f LN2 mode workaround. Seems they handle post differently now to before. A little sad it didn't work when I just started to find it useful.

I actually did load optimized defaults beforehand and afterwards, I even tried multiple CMOS resets, choosing load optimized defaults and then exiting I even flashed it again with normal Q-Flash, along with the backup BIOS but to no avail. I'm starting to think this is an actual bug in the BIOS. Guess I'll try to short the pins or rip out the battery if I can even get there without removing a bunch of stuff when I get some time this week.

If this is happening for anyone else with F20a please let me know.
