It is an unknown factor at the moment @spurdy. If one manufacturer decides to have a go at supporting the 4000 series (there are a couple X370/470 boards out there with 32mb ROM chips) then chances are all the other manufacturers will rush to support them as well by doing things such as removing surplus microcode as they won't want to be made to look bad. In all honestly though there is absolutely no excuses for X470 boards particularly not having ROM chips big enough to support the 4000 series AMD know what their roadmap is and thus internally inevitably would have known some time ago (likely dating back to 1st gen Zen) a larger AGESA would be required in future so could have easily informed manufacturers of this and advised larger ROM chips for future development. If it turns out even X470 boards don't get official 4000 series support then I'd have to think that the move was a play made just before X470/B450 was released to get AMD and board manufacturers more money while publicly AMD have the somewhat dirty explanation of "We said socket AM4 would support up to at least Zen3, not that every chipset on the AM4 platform would support up to Zen3."

In my book, thats a dishonest, sly, disgusting move to make. It is however as I have said all along during AMDs revival; their aim is to make money not be your pal so just like you would any other company you should take what they say with a large dose of skeptisism until it actually happens.

AMD made a turn

AMD Reverses Course, Will Enable Zen 3 and Ryzen 4000 Support on B450 and X470 Motherboards.

ps KET, can you give me an update about the modified X370 Gaming K3 F50a bios.

I'm glad for the owners of 400-series boards that some might end up with Zen3 support. However, at this point, after digesting all the info (particularly the Gamers Nexus series covering the issue) I think I'm ready to place a bet that F50a may be the last & best we get for the AX370 Gaming K7.

@ket, I'll be DM-ing you about chipping in for an F50a mod here shortly!

@spurdy I've heard rumors X370 will see support for Zen3 as well, so I wouldn't be giving up all hope yet ;) I'd already toyed with reverse engineering an X470 firmware for X370 anyway to get Zen 3 support. Interesting times ahead it seems.

x370 gaming k3 + Ryzen 3700x

Hello friends, I am happy to have found this forum, I am Brazilian, I will be here following news about the new ryzen Gen3 processors, I have an ax370 gaming k7, I hope we can keep them in this new generation! thanks for not letting go of these first generation wonders! <3

I've been playing around with modding my Gaming K7 and am trying to figure out how you were able to mod UEFI to be HD on the post screen. Hopefully you know what I'm talking about and can offer feedback. Thanks for you help!

Edit: Nevermind. It looks like Gigabyte disable Windows 10 WHQL for some reason in their latest BIOS's. I re-enabled and all is well.

Hello there!

Right now I have my hands on a Gigabyte AB350M Gaming 3. I though this board would have an option for PCIe bifurcation - at least Asrock and MSI already provide this for their 300/400 series boards.
Unfortunately there is no such option.
I need this to switch main slot from x16 to 4x4 to make a quad nvme card fully usable.

I've tried unlocking the PBS menu (it has the related "PCIe/GFX Lanes Configuration" entry) by modifying AMITSE as mentioned in post #175 (using latest 50a bios).
I can access the PBS menu now, but changing values doesn't do anything :(

Does unlocking PBS need any additional steps to make these options working?
Any other ideas how to make this work are also welcome.

THANKS,

MARK

Ket,
Do you have the firmware for the X370 Gaming K7 done F50a? Do I just paypal and send an email?
