The BIOS is actually not dated 2020-06-22, as when you extract it, the BIOS file is 2020-06-10 that is also what displays in CPU-Z as BIOS date. This is older than the beta BIOS that was the E3 release which was dated 2020-06-12, which is 2 days newer. That is why I am suspecting MSI uploaded the wrong BIOS version. I would have expected a BIOS date of 2020-06-22.

You are exactly right.  Why MSI does that, I have no clue, but I confirm this is not the first time we have seen this.  I will flash the 1.006 final later today.

I did not use this modded bios. I used the stable BIOS from the MSI download pages. Which apparently is older than the latest beta bios.

No OC and no PBO, only memory manually set, fan-curves, and the CPU features all set to enabled.

Edit: Maybe MSI have accidently uploaded the wrong BIOS version? As it also shows as E0 instead of just E.
==============

I can report that the X470 Carbon Pro BIOS version 7B78v2E with a Release Date of 2020-06-22 is *NOT* stable.

Using the exact same BIOS settings as the BETA 1.006 version, it immediately broke my system.  Two out of three benchmarks threw up BLUE SCREEN crashes.

I immediately went back to the 7B78v2E3 (Beta version) with a Release Date of 2020-06-12, and it returned to 100% stable - even with a healthy overclock.

So the BETA is actually much more stable in my particular hardware config.  I have no clue why the (BETA) BIOS 1.006 version is MUCH MORE STABLE than the (FINAL) one.  But I can tell you without question that the BETA is much more stable.

The download link for the (beta) has been removed from the MSI support site for this motherboard, but is still active (don't know for how long).

Do we have support here? Can someone verify bios version officially?
===================

You should know that with the X470 Carbon Pro using a 2000-Series CPU you should stick with one of the older BIOS versions.  Later versions using this motherboard and a 2000-Series CPU causes serious compatibility issues that you CANNOT REVERSE once you flash one of the new BIOS versions.

THAT being said, WHAT CPU ARE YOU USING with this motherboard?  Once we know that, we can help point you to the best BIOS for the specific CPU you are using.

Important thing: initially this motherboard did not support my CPU when i just installed it, so i bought old cpu (1300) just to update bios to latest 2019 version. I don't want to experiment with unstable bioses, because i'm not sure i will be able to revert changes :( I want to be 100% sure that new (marked as stable) bios is really stable. I want to update it because my system can not start after cold boot with standard memory XMP profile (require 3 restarts), everything else is fine.

Hi, I have been running the released BIOS now for about 3 days. So far for me it has been rock solid stable. However, I do not use the XMP profiles, I have set memory speed and timings manually according to Ryzen DRAM Calculator.
My memory has Samsung B-die chips, I have not encountered any cold boot issues, however I also did not encounter those on the previous 1.0.0.4 AGESA based bios.

I did file a ticked with MSI, they have not replied yet, to ask them to validate if this is really the final BIOS. As one, it is 2 days older than the previous beta bios, and two, it is 12 days older than the bios date that they post on the download page.

My system specs:
AMD Ryzen 9 3900X - G.Skill Ripjaws V 32 GB DDR4 @ 3600 MHz C16 - MSI X470 Gaming Pro Carbon - Asus ROG Strix RX 5700 XT - Adata XPG SX8200 Pro 1TB - Intel 660p 2TB - 850 EVO 1TB - 830 256GB - Barracuda 2TB - Liquid Freezer II 280 - RM850x - LG 34UM68

Well, you've got an exceptional CPU/Motherboard combo there that will keep you on a par performance with any X570 (using M.2 PCIe3) platform for the foreseeable future.  

(The M.2 PCIe 4 performance gain is not that much of a gain under normal conditions)

re: BIOS

You've got THREE options with that 3700X.  The two released in July 2020 are mainly to finalize support of the newly released 3600/3800/3900XT cpus.  Your 3700X will perform just as good as any of those newer "XT" versions under 'stock' CPU and DRAM speed settings.

If you want "100%" stability with any of these for both your CPU and your DRAM, you should not O/C your 3700X beyond 4.0 in order for your DRAM to still run at full XMP profile speeds.  Overclocking your 3700X beyond 4.0 will greatly impact the reliability of your DRAM being able to run at full XMP profile speeds.

You can interchange (flash up or down) with any one of these without damage to your motherboard, so you can try all three of them for your hardware config that suits you the best.  I have bounced back and forth between all three of these and the July "2E3" 1.006(Beta) works best for my preferences (I O/C to 4.2 and keep XMP Profile enabled).  Just make sure you set your BIOS to "DEFAULT SETTINGS" both *BEFORE* and *AFTER* you flash your BIOS to avoid hardware IRQ conflicts.

=================

The 3900X is a fantastic CPU for the X470 Carbon Pro.

You said it was running 'rock solid stable' on your MB, so why was it necessary to 'file a trouble ticket' with MSI if it is 'rock stable?'

Post the answer here, thx. I will act accordingly. If it is stable i will try it.

Its overclocked to x39. Everything is stable after restart, just can't load from cold boot. No matter if use XMP profile or MSI "Try it!" function (only difference is Try it sets 1.4v vs 1.35v(XMP)).

Stange thing is - this memory is marked as compatible on AMD site ("Ready for 3rd Gen AMD Ryzen"), but not in MSI compatibility list https://www.msi.com//Motherboard/support/X470-GAMING-PRO-CARBON#support-mem-19 I don't understand why. May be they just don't want to? :/

Exactly how I stated. There is confusion about the BIOS version numbers and BIOS dates. Normally the release BIOS should be newer than the beta BIOS. In this case the beta BIOs is the newer version, in terms of both version number and bios compile date. To prevent that I am running a beta BIOS and to also make MSI aware, I have filed a ticked.

On what is the above based? Overclocking Ryzen 3000 series CPU's is generally a bad advice. As you loose the single/low threat performance benefits of the boost behaviour. If you want to boost your multi threat performance might as well enable PBO.

I have build several PC's based on Ryzen 3000 series. On my personal rig I have manually tuned memory speed and memory timings. As my memory is rated for 3200 MHz C14, I am running it on 3600 MHz C16 on stock voltage.

However on the rigs for my friends that I have build all use XMP profiles without any issues. (ether on 3200 C14 in combination with a 3800X at stock or 3600 C16 in combination with a 3700X at stock).
Memory stability has nothing to do, as far as I am aware of, with the CPU overclocks, as the Ryzen 3000 series has a separate chip for the IO, infinity fabric and memory controller.

I have read into optimally tweaking Ryzen performance. However, non of the articles I have read relate to core overclocking to memory speed stability. It all relates to the infinity fabric, being 1:1 or 1:2 speeds etc. For lowest latency you want your infinity fabric to run 1:1 speed with your memory (eg. 3200 MHz memory means 1600 memory controller and infinity fabric, 3600 MHz memory means 1800 MHz memory controller and infinity fabric).
Going above 1800 MHz will make the infinity fabric divide by 2. As it is only rated as stable till 1800 MHz on Ryzen 3000 series (3000XT series it is said to be stable and 1:1 till 1900MHz therefor 3800MHz memory).

I have received the answer from the MSI support team see below.
However, I still cant explain why the compile dates (and version number) from the beta BIOS are newer than the final bios.

Answer from MSI support team:

Dear Barry Schalker,

Thanks for contacting MSI technical support.

Regarding your concern, bios 7B78v2E0 is newer version, please don't worry.

Thanks for your cooperation in advance!

Best Regards,

MSI Technical Support Team

This is how MSI names their BIOS. You can search for other board and you will figure out the naming rule. 
For example, beta BIOS goes from 7B78v2E1 to 7B78v2E2 than 7B78v2E3. And finally comes to the release version 7B78v2E. (I'm guessing they reset the number to 0 -> 7B78v2E0)

Thank you. Just updated to latest version (E). It now starts from cold boot with standard XMP-profile YaY!

Could also be that you have received a faulty CPU. Hard to tell.
I am running the release bios now a few weeks on a 3900X 100% stable.

You have older model 3900x that work, I have no idea faulty 3600XT that newer model won’t work with current bios, I did not see any new patch notes for support XT model on their website at all.https://www.msi.com/Motherboard/support/X470-GAMING-PRO-CARBON

Since I had flashed one of the newer versions of BIOS I cannot downgrade? What would be the correct version for a 2700x? Would it be 7B78v24 or 7B78v26 ? Thanks
