ASRock B550M-HDV Supports 3rd Gen AMD AM4 Ryzen/Future AMD Ryzen Processors Motherboard

Rock solid, and beautiful board too. The lighting on the motherboard can be turned on/off in the bios. I have it with a 5700x, all ddr4 slots, 2 nvme ssds, 2 blu ray drives, 3 sata ssds and a humble radeon RX560. In Linux kernel 6.10 everything works out of the box, suspend/sleep is also good. If you're not on AM5 yet, this will keep you in business for years to come.

Ignore ppl complaining about boot issues you just need to make sure you have 3200 mhz ddr4 and make sure you give the board time to do its first boot, mine took about 30 seconds but after that it was fine, it took a ryzen 5600 no issue. Vrm temps are stellar even in a cramped SSF build. Pci E 4.0 x16 and a gen 4 m.2 slot plus gen 3.0 m.2 makes this a very compelling board

I got this to replace an ASUS X570-P which had repeated failures. I didn't need the extra couple of PCIe 4.0 slots a x570 gives you so I figured dropping down to a B series board wouldn't hurt. I'm getting much better thermal readings compared to the x570 and the lack of a fan is nice. I also like the diagnostic LED which helps immensely when a machine won't start.Initially the board wouldn't boot getting stuck on code 1A which isn't listed as one of the codes in the manual. This appears to occur when the processor is newer than what the BIOS supports. Luckily this board supports BIOS flashback, even with no CPU inserted, so upgrading it was fairly easy. All you need to do is copy the current BIOS file to a USB stick, rename it to creative.rom, and insert it into a specific USB slot that's marked on the back. Then you hold a button on the rear IO panel until it starts flashing and wait about 5 minutes for it to stop. That's it.

Notes for people with problems:AMD Chipset Software 2.13.27.501 works for me, but the recommended 2.11 on ASRock's website causes my whole PC to sort of pseudo-freeze at random intervals. So I would recommend getting 2.13 if you're having any issues like that.If you have LEDs flashing randomly and they won't follow what you set in Polychrome or BIOS, you probably have a bad board.I'm running this B550 Taichi with a 5800X, GTX 970 (the GPU shortage is ruining me), 32 GB Ripjaws V 3200 CL 16 RAM (2x16), an EVGA 650 G2, an Arctic Liquid Freezer II 360, an M.2 SATA SSD, a SATA III SSD, and a PCIe SSD.It's an absolutely incredible board for the chipset and money. Something a lot of X570 boards don't even have at this price range is x16/x4 and x8/x8/x4 support for the PCIe lanes. As someone with an x4 PCIe SSD for games, I appreciate the bottom slot being really far away from the graphics card slot and still able to run the graphics card slot at x16 while in use.The I/O is stellar. You won't find another B550 with the same number of USB 3.x ports *in addition to* all the other storage/PCIe slots. And BIOS flashback. And clear CMOS buttons. And a POST code display. And RGB. And Intel 2.5Gb LAN. And a front USB-C header. Sure, the price is a bit high. But given that you can't buy half of the best boards right now, it's a steal. Its original MSRP was $230, which is insane value. But now, with the inflation of all the prices of everything, $270 is good. I wanted the ASUS Strix X570-E, but it's hovering around the $400 mark instead of its usual $299. So yeah, I'm just fine with $270.The BIOS works. I'm a non-overclocker so I just want to set my RAM frequency, see my CPU temp, and see occupied slots for troubleshooting. It does that.The board armor is neato. It makes me way more comfortable while working on it.The first one of these boards I received was scuffed-- the I/O cover RGB strips were flashing random colors, even though the rest of the LEDs were responding to the ASRock Polychrome software normally. I also had a USB port not working. It was one of the USB 3.1s, and it was the second one from the bottom of the board... which was weird. Also the Taichi symbol on the I/O cover was not lighting up at all. Another issue was that the latest AMD Chipset driver (2.13.27 as of the time of writing) was causing my USB devices to randomly disconnect (even with the AGESA code update in the latest BIOS). I called Amazon, they referred me to ASRock, and over a period of two days and about six emails, they recommended I get a replacement board. I did, and I'm glad I did. The new board works exactly as expected. Additionally, the new chipset driver works perfectly.
