This is all pretty much FUD. > x570 -> Requires active cooling (fans) on the chipset because it throws off too much heat. The proprietray fan will die and your motherboard needs replacing. AMD does require fans on the chipsets for X570 boards, but different board makers have treated this differently. My understanding is that some boards don't spin it up unless you're putting some serious PCIE 4.0 bandwidth in. Either way, "The fan will die and needs replacing" may be true someday (as it would be with any fan), but is not a guarantee. >x470 -> Don't even look at your memory the wrong way if you want it to boot. Also, you need an older gen Ryzen/Athlon to update the BIOS to something that works with Ryzen 3000. Sure, there are stickers all over the box touting 'Ryzen 3000 compatibility!' but that's only after you update the BIOS. The BIOS the board ships with won't work at all. First gen Ryzen (1000 series chips) had some memory compatibility issues, but 2000 and 3000 chips haven't had many issues. It's true that you needed to do a BIOS upgrade on x470/B450 boards when 3000 series chips were released, but those stickers indicate that the board maker installed a newer BIOS and they should work out of the box. Unless you manage to find an X470 board that's been sitting on the shelf since before last July any x470 board you buy today is extremely likely to be compatible with all currently released Ryzen chips out of the box. > b450 -> Dicier to run new stuff on such an older platform. The implementations are supposedly power weak for higher core count 3900/3950 CPUs. 3000 series chips use a smaller process and are more power efficient per-core than 2000 and 1000 series chips, so you should have no issue running an 8 core chip in a B450 board. 12-core and 16-core chips might have some issues, but who buys a $79 motherboard and sticks a $500/$900 CPU in it?

Both had non-compatible BIOS that wouldn't work with 3000-series. One so old that Dr Debug wouldn't even do anything. Just blank. It's not just me. Read the negative product reviews of almost any x470 boards, and you'll see memory and non-POST issues very recently (followed by the response macro from mfg'er saying everything is fine just use 1 DIMM, etc). It's very much a crapshoot with AMD chipsets. You get a good one and everything's great. You get a few bad ones and you're stuck in swap/return/RMA hell. Also, how can it be FUD when it's exactly what I went through? Edit: The "Ryzen 3000 compatible" stickers do NOT mean it will work out of the box. It means that it CAN work...after you update the BIOS with an old CPU. AMD will offer you a CPU "boot kit" to get it going, but you're risking on missing out on many 30 day return windows with shipping, covid19, processing, etc. Avoid it all and just get an Intel until the next refresh.

  Interesting on your x470 experience. I bought a X470 Taichi U from Scan UK in early February, and the 3600 chip worked. I was wary of the issue you raise, but lucked out, and figured the issues you talk of had washed through. Maybe the warehouse staff who boxed it looked at the order and gave me a recent unit. What action could AMD take to improve the situation? I wanted to go to AMD because I expect to get strong upgrade options from it - certainly to a 3950x, and possibly further. But - a complication of that is that older motherboards need BIOS updates. I am surprised at how slap-dash the motherboard is. It supports ECC ram - great. But BIOS configuration is a confused mess.

    Not familiar with Scan UK but I would bet they don't resend RMA boards endlessly like Amazon sellers might do.

    Some motherboards supports flashing BIOS through a USB thumbdrive without a CPU, IMO this kinda of problem would be a non-issue if all of them did this.

      To some degree, yes. However, that assumes a functioning BIOS release is available and works...many incremental releases are no functioning despite release notes saying otherwise. Many times, you can't downgrade the BIOS either. So you're stuck with a bad board waiting for a beta BIOS...fun times! The workstation/server platforms ARE better. Having a BMC to flash/recover things is much more reliable.

  > a pair of x470 Taichi's from Amazon last month So, you bough the same board twice and expected different results, and then are painting all motherboards with that experience. It's unsurprising that motherboards need microcode updates to work with newer CPUs. Intel CPUs also worked that way, except that 1) they only rarely support a socket for more than two generations anymore, and sometimes not even that, so you physically need a new motherboard to upgrade your CPU anyways, and 2) Intel CPUs haven't had any major architectural changes since 2016.

My Vive stopped working on my AMD machine, and it eventually required a bunch of BIOS and firmware updates to get it working again. On the upside, I had already made the updates to support the new Ryzen CPUs and so picked one up when they were on sale. There’s probably a little more dodginess to the overall AMD ecosystem, but I expect that to be shaken out shortly (if it already hasn’t been)
