Over the past week, we closely reviewed your feedback on that news: we watched every video, read every comment and saw every Tweet. Our experience has been that large-scale BIOS upgrades can be difficult and confusing especially as processors come on and off the support lists.

As the community of Socket AM4 customers has grown over the past three years, our intention was to take a path forward that provides the safest upgrade experience for the largest number of users. As a result, we will enable an upgrade path for B450 and X470 customers that adds support for next-gen AMD Ry zen Processors with the Zen3 architecture.

These optional BIOS updates will disable support for many existing AMD Ry zen Desktop Processor models to make the necessary ROM space available. The select beta Biases will enable a one-way upgrade path for AMD Ry zen Processors with Zen 3, ” coming later this year.

To reduce the potential for confusion, our intent is to offer BIOS download only to verified customers of 400 Series motherboards who have purchased a new desktop processor with Zen 3 inside. This will help us ensure that customers have a bootable processor on-hand after the BIOS flash, minimizing the risk a user could get caught in a no-boot situation.

As we get closer to the launch of this upgrade path, you should expect another blog just like this to provide the remaining details and a walkthrough of the specific process. We’ve spent the next three years working very hard to fulfill that promise across four architectures, plus pioneering use of new technologies like Chiclets and PCIe Gen 4.

The complexity of this situation is exactly why AMD decided to shift support for Zen3 to 500-series chipset motherboards in the first place. To reduce the potential for confusion, our intent is to offer BIOS download only to verified customers of 400 Series motherboards who have purchased a new desktop processor with Zen3 inside.

B450 and X470 boards upgraded for future socket AM4 CPUs will lose support for older chips. Back then, MSI was forced to issue a statement reassuring people that their boards would support Zen 2.

Less than two weeks ago, AMD announced the future of the AM4 socket: upcoming CPUs like Zen3 would not work with B450 and X470 motherboards. Therefore, users pairing a Ry zen 3600 with a B450 board effectively didn’t even get a single generation of upgrades.

There’s a definitive technical reason, which AMD explained at the time; MSI had to cut down their interface on B450 boards just to support Zen 2, never mind Zen3.

Alarm bells also rang as AMD announced X570 without support for Zen 1 processors. AMD also listened to the enthusiast community, as users made their feelings clear on various forms of social media.

Having boards floating around that don’t support the CPUs they launched alongside is not a situation AMD want. There’s also the problem that some users like to upgrade to the latest BIOS even if things are working fine.

If a user with a B450 or X470 board and 2000 series CPU upgraded to a Zen3 BIOS, they could brick their system. With enough strong feeling among users, AMD have decided it’s worth the drawbacks.

As of today, AMD have announced that Biases will be developed for B450 and X470 motherboards that work with Zen3 CPUs. Firstly, as part of the announcement AMD said “These optional BIOS updates will disable support for many existing AMD Ry zen™ Desktop Processor models to make the necessary ROM space available.” Just how many CPUs will be lost isn’t clear, and probably depends on the engineers.

Fourth, AMD have noted that these updates won’t necessarily be available right away. The CPU support for different chipsets as it stands now, fully annotated. These aren’t just excuses.

That means for most people, even with a high-capacity BIOS chip and capable Arms, there’s a good chance their new PC will use different memory technology anyway, so a platform change will be forced regardless. I like to play with lots of different hardware, and I value the flexibility to run many generations of processors on a single motherboard.

Should AMD aim for bigger BIOS chips in the future? A couple of weeks ago, news came out regarding Zen3 and its lack of backward support for X470 and older motherboards leaving users disappointed.

YouTube came alive offering explanations and reasons why this was so (referencing the size of the ROM and code needed for the new CPUs). The process is multi-faceted due to the technical complications of the implementation, however, this is great news for AMD users with B450 and X470 boards.

Will it be reserved for all segments or just a couple of SKUs as to not pilfer sales from the newer, feature rich/more robust X570 series? Over the past week, we closely reviewed your feedback on that news: we watched every video, read every comment and saw every Tweet.

(please take the Poll: Do you plan on updating your MSI X470 /B450 Motherboard BIOS to run Ry zen 5000 'Vermeer' Zen3 CPU?) The AMD Ry zen 5000 Series 'Vermeer' Zen3 Desktop CPU will become available in November 2020.

The exact version number will not be known until MSI implements Version2 for their 400-Series motherboards in January 2021. MSI has partnered with AMD in past announcements pledging to support Zen3 (Vermeer) CPUs on their X470 and B450 existing line of motherboards.

Please post any (successful) BIOS updates that MSI releases for your X470 / B450 motherboard here, along with “lessons learned” and what does and (does not) work. MSI Announces Zen3 Support for X470 / B450 motherboards. Download access to the Zen3 BIOS for the X470 / B450 motherboards is still under development.

AMD may require a serialized Zen3 CPU number be submitted prior to being able to download the Zen3 BIOS for your MSI X470 / B450 motherboard to prevent “BRICKING” your motherboard into being “unsuitable” due to CPU / BIOS version compatibility. This MSI Insider video also showed that 300-series boards aren't expected to support the new microarchitecture.

In the MSI Insider presentation, there was a background slide which showcased which processors and which motherboards were compatible. The hosts to the MSI Insider, Eric Van Burden, and Michael Berthoud made an interesting point that when users flash their BIOS to offer support for these motherboards may lose support for the older Zen microarchitecture.

RUN Hardware created an informational recap (update) on the Ry zen 5000-series. His sources appear to be valid. Both will be able to run the Ry zen 5000 (with AGES BIOS update coming from MSI).

It is looking like ALL MSI motherboards (including X570 and B550) will need a BIOS update to run Ry zen 5000. Per the AMD Official BIOS UPDATE release for the X470 and B450 motherboards to be able to run Ry zen 5000-series CPUs. No AMD Ages Fabric BIOS updates will be available for these motherboards until January 2021.

AMD's sales strategy for the Ry zen 5000 CPU upgrade is not going to be well-received among existing X470 and B450 motherboard users. Their strategy to withhold Ry zen 5000 Ages Fabric BIOS upgrades for those users until January are primarily for sales profits by forcing hundreds of thousands (if not millions) of X470 and B450 users to upgrade to the X570 and B550 AMD motherboards in order to realize the gains of the Ry zen 5000 CPU. This is not a good trend for AMD, and I predict many MSI X470 and B450 users will “SKIP Ry zen 5000” altogether because of the way AMD is neglecting those users by forcing them to “WAIT AND SEE” for over three months just to be able to discover whether X470 and B450 motherboards will (or will NOT) fully support Ry zen 5000.

To be fair if you read the initial announce way back when more CLOSELY its says they will support next generation Ry zen *4000* series desktop CPUs. **********************The Jan 2021 X470/ B450 AMD BIOS releases will all be BETA for Ry zen 5000 series.

This is going to be a LONG wait, but at least AMD is willing to inform X470 and B450 users on what/when to expect in terms of Zen3 BIOS support in the coming months. We’re excited to announce the AMD Ry zen 5000 Series desktop processors with the groundbreaking Zen3 architecture today.

Based on the new levels of gaming performance the 5000 Series enables, we’re certain many of you are already excited to upgrade and making plans to do so. In an effort to keep you informed as promised on May 19, we’re sharing more on the status of BIOS updates for motherboards with AMD 400 Series chipsets.

As a reminder, this is the final upgrade path AMD can enable for 400 Series motherboards. The AMD Reddit Zen3 support for 400-Series motherboards topic has only been posted for two days, and already has 737 comments, with hundreds of people asking the same question WHY DO WE HAVE TO WAIT UNTIL January 2021 to install Zen3 on our 400-Series motherboards? I have not posted on AMD's Reddit page, but here is an observation from an MSI Tomahawk Max owner sounding very surprised if MSI does not release a working Zen3 BIOS right now, with NO WAITING.

I hope that that January 2021 date is there to remove pressure from mob vendors, and not the date on which AMD will give mob vendors the green light to push those Biases. MSI comes out of the gate with BIOS revisions based on AGES Combo-A4 v2 1.1.0.0, so you are ready to go with optimized code for Zen3.

Here are the links (and course check back after Ry zen 5000 lands at retail, as MSI could issue another round of BIOS updates)... Motherboards based on AMD's X570, B550, and A520 chipset with AGES v2 firmware installed (starting at 1.0.8.x or 1.1.0.x) should be good to go.

But you might first want to note how Intel has not just been disappointing to consumers, but flat out consumer hostile throughout its history. If it does as promised and takes the gaming crown cleanly then I'm positive sure it will be the go-to platform for people trying to get the highest FPS numbers and sell like crazy. If there's one thing Intel has in-grained in us it's that upgrading the platform with every CPU generation (even the ++++ ones) is “normal”.

The BIOS updates that 'bricked' so many boards when done with the wrong CPU by people who're not really adept at such techie challenges anyway. I'm very comfortable with AMD...and MSI, for that matter...playing it safe this time and releasing it onto the 500 series platforms they KNOW will work well first.

AMD should not be blamed for those bricked boards as long as they release the BIOS upgrades with sufficient disclosure, warnings, and detailed risks of doing so. AMD's first approach to upgrading the 400-Series chipsets to Ages Version 2 firmware was to use an allocation system where the customer would first have to prove they had purchased a Zen3 CPU BEFORE the customer was allowed to even download the Zen3 BIOS for their 400-Series motherboard.

HU points out that the vast majority of users will NEVER NOTICE the average performance differences between PCI3.0 and PCI4.0 in 98% of daily use. HU confirmed with AMD that there will be 0% performance difference to be seen when running Zen3 on either 400 or 500 Series motherboards.

This (very small) performance gain comes at a steep price premium and will be invisible to most users, and won't even be noticed. HU uses the MSI B450 Tomahawk Max as a perfect example of why 400-Series boards are more than sufficient for Zen3.

We all made our choices, and now we have to live with them. Nine months isn't a problem unless you the impatient type. The issue is a lot of people got the max series because it was specially sold as the boards to get for upgrade to zen3.

At the time the b550 chipset was heavily delayed with no release date confirmed. Trouble was, you couldn't find a x570 board with good rating since they all got trashed at initial release for early adopter problems.

B450 owners are now crying begun they made a mistake and chose poorly. The research would have shown the same thing, especially the max boards which were altered to work with zen3.

Ok, maybe I shouldn't be so hard.to me marketing is that thing were they put Ry zen 3000 desktop ready on the packaging. If promises were made they didn't reflect that in the packaging, the manual, or at the retail site where I bought it.

Staggering the releases would be a good idea for tech support reasons. Hmm, where else did I hear about making the waves smaller and flattening the curve.
