x570 Taichi - all the issues I've had thus far

Do you know if LEDs are on by default, and is there any way to disable them from the firmware? I'm planning to get X570 Taihci, but I'm going to be using it on Linux, so I need to be sure that LEDs can be turned off without requiring to use Windows only tools.

After playing with the settings and trying out different stuff, the easiest solution is to install ASRock Atuning. With this you can easily configure fan curves, you can test fan speeds etc. What I have noticed is that temps for chipset are around 59 - 62 celcius, regardless if fan spins 2500, 3000 or 6000 rpm. So I have set SB_Fan so that until 63C it is 25% and 65C 30%, these are basically silent and temps won't exceed at least for me higher. If you have much higher temps you need to plan airflow better. On a final note, X570 is either on or off, so it doesn't undervolt on light use. So the temps what you'll see idling in BIOS are your regular temps. Try to be around 60 celcius mark.

I set the Chipset fan to "Quiet" in the Bios. This has it sitting at about 2500rpm at about 57c (+/- 2c). You are right in that it's not too bad at this volume, and as soon as I put some load into the system or some noise in the room, it is inaudible. Unfortunately, with 6 ML120 maglev Corsair fans in the case running at 1000rpm when not under load, it's still the loudest thing in the room when the PC's at Idle. In the grand scheme of things, if this was the only issue with my board, I'd be fine with it.

OP, manual says every PCI-E slot is x16 so try moving to middle slot, this fixes your usb-c header problem. U recommend this, interesting video and MB is x570 taichi, he also has reviewed on another video: https://youtu.be/D5l1MUMHXt0

The manual states the following:

3 x PCI Express 4.0 x16 Slots (PCIE1/PCIE3/PCIE5: single
at x16 (PCIE1); dual at x8 (PCIE1) / x8 (PCIE3); triple at x8
(PCIE1) / x8 (PCIE3) / x4 (PCIE5))

This implies that only the top slot is wired for 16, as it specifies that when only one slot is in use, the slot that runs at 16x is slot 1. Middle slot is likely only wired for x8. Given that I've run this GPU on a PCIE gen2 mainboard with no loss in GPU intensive benchmarks, I'd say it could run in a x16 slot that's only wired for x8 just fine. But my next GPU may not be so kind. Yes, the easy solution is to unplug the header and that's likely what i'll do in the long run, but it's kind of like buying a car where the electric windows won't operate if you have something plugged into the lighter socket. It's not a deal breaker, but for those people who want to use both those features at once, it'll get SUPER annoying, SUPER quickly... and smacks of poorly thought out design, because it's not something you should have to implement a workaround for...

lights can be controlled in the BIOS and in windows software. can be set to all off. board actually still looks very good with the lights off, I have mine set to a static white, which is actually more of a blue-white. It looks good and is inoffensive.


In light of the ongoing BIOS issues related to AMD, I'm probably going to stick to the plan from my last post, and await a level of BIOS maturity i (somewhat naively, perhaps) would have expected this line of boards to have hit the market with. In that time i'll wait and see what else happens in the world of enthusiast computing!

It does say three times PCI-E 4.0 x16 slots and lists the available slots. I agree the latter part is a bit confusing, but I think it tells user that when you want two GPUs, use slots 1 and 3, not 3 and 5. I think you need to test, mode can be easily seen/confirmed if that is x16 or x8.

You're right. I did need to test. So I pulled out the you riser, and shone a flashlight into the slot. Can confirm PCIE3 is a x16 physical slot, only wired up to the x8 connector. There the silver contacts stop, and it's black plastic from there back. So a hard no on any slot other than the top being x16.


As for the rest of it, I'll keep tweaking and tinkering, and learning from others' experiences with this board, chip, and chipset.

It'll be interesting to see it unfold.

PCIe 3.0 x8 is still more than enough for modern GPUs, you shouldn't have any issues running at x8, I have not seen any performance drops using any of the GPUs I have tested in x8 slots. Dropping to an x4 slot may cost you 5-10fps on a high end GPU in some games but even there, generally your performance will remain unchanged. Moreover, if you game at higher resolutions than 1080p the GPU will become a bottleneck LONG before you eat up your PCIe bandwidth, even on an x4 slot. This becomes an even more moot point if you are able to utilize PCIe 4.0 which effectively doubles PCIe 3.0 bandwidth. At present I believe only AMD's new 5700 series GPUs support PCIe 4.0 however.

This is a little understood area for a lot of people, I hope this helps to clarify.

Good to know thanks!
