Most Stable B650 Mobo for AMD 7800X3D

[SunChief]

Hi all

Through some research I've come to find that a lot of the B650 mobos in this range have had some issue or another regarding BIOS and RAM/EXPO (even with RAM kits that are on the QVL)/random reboots/etc. I've also seen cases of users who have the same components, with some of them experiencing these issues and some of them having no issues at all.

My question is - After a BIOS flashback to the latest version and using a RAM kit on either of the mobo's QVL (6000MHz; CL30) with an AMD 7800X3D, which of these options would likely be the better pick as far as stability goes? I'm not as worried about what makes one board better than the other so much as just having as smooth of an experience as possible. I know this depends very much on the BIOS version installed from model to model and it looks pretty much like a coin toss as to whether I'm going to possibly run into issues or not. Thanks in advance!

• Gigabyte GA-B650-AORUS-ELITE-AX -- First pick for a lot of people. Was my first choice but on reddit I see a lot of issues with it not posting/rebooting/etc. Even up to a month ago. Ideally I still would prefer this one, but I'm a little weary now.
  
  
• MSI MAG B650 TOMAHAWK WIFI -- This board is also looks to have issues, including long boot times, but is generally regarded as "good".
  
  
• ASUS ROG STRIX B650-A -- I see people saying they've sorted out the issues with burning CPUs in their later BIOS updates.
  ASUS TUF GAMING B650-PLUS -- Slightly cheaper (and uglier) alternative to the STRIX.​

Any board with 12 phases 60 Amps VRM's will be more than fine.
Don't need more than that. In fact even 6 or 8 phase VRM designs runs a 7950X which is much more power hungry that a 7800X3D . No one would pair the two but it can deal with both those CPU's.

Gigabyte have been rock soild from the beginning , unlike MSI and ASUS . Both MSI and ASUS have largely sorted out their BIOS issues. ASRock have also really done well with their AM5 lineup but the local suppliers are useless and there is not much stock floating around.

I have been stupidly blown away by the Gigabyte B650 Gaming X AX, specifically since AGESA 1.0.0.7. If you asked me to put together a system with a R 200k budget, I'd still go for that board over anything Aorus, anything Strix, anything B650E/X670/X670E, unless you have very specific needs such as 4+ NVMe drives. The price of the board along with what it's capable of (in terms of memory) just makes it a no-brainer for me. Unless the boards you're looking at can be had FAR cheaper than the Gaming X AX, it gets my vote.

Generally speaking you want as many power stages/phases as possible and as big as possible for the cpu, starting off about 8 stages with 60a each is good enough in terms of trade offs between heat, power, stability, cooling, cost. Be aware you should aim for single or direct stages and avoid doublers, dual or twin stages basically means exactly half in terms of single stages. One power stage for the ram is sufficient, though two stages is better.

The whole frying-your-cpu saga should be largely over with the latest bios installed
