Help on Asrock X570 Taichi motherboard

[Jinu]

Hi Folks

I have just bought a new ASrock Taichi X570 motherboard. Since the bios that came with the motherboard did not support the 5000 series chips i ugpraded the bios to 4.0 (latest) and completed the full setup. Initially no problem noticed. But now the following issues are happening.

- The motherboard when i switch it on (just the PSU) the RGB leds of the motherboard come on but the light of the onboard power button and reset button do not come on.

- If press the power button, the mother starts the post process and then suddenly reboots (before even showing the ASROCK logo). Then it automatically boots again and this time it completes the boot process and comes to the window login screen. This happens every time i switch of and on the PSU.

- At the windows login screen, it randomly powers off (sometimes it does not and seems to work well), but most times its powers off. When it powers off then i cant seem to power up the motherboard no matter how many times i press the power button. everytime, the light in the accessories flicker and then it switches off. When it switches off the RGB lights of the motherboard are still on.

 

What could be the issue any ideas?

You have to enter bios and load default settings in bios then save and exit.

either press f2 or delete key which ever is mentioned in your motherboard manual to enter bios

I did that. I downgraded the BIOS to a lower version also. Did the clear CMOS switch thing also. Before i go further let me specify my config

- AMD Ryzen 5600x

- ASROCK Taichi x570

- Crucial Ballistix RGB 3600 MHz DDR4 DRAM  - 32GB

- Corsair MP600 512 GB SSD

- WD Black 750 1TB SSD

- Gigabyte 3060TI Gaming OC graphics card

- Lian li Galahad 360 AIO

- Corsair RM650 PSU

 

Exceptt for the PSU all other components are brand new. The taichi motherboard has a 8PIN and a 4 pin CPU power connector. My PSU does not have a 4 pin CPU power connector and from what i read on the net the 4 pin power connector was required only if we were using high end CPU or was into overclocking. So i connected only the 8 pin power connector and not the 4 pin

 

While studying the problem i realised the once the error occurred, the PC would not turn on not mater how many times i press the power button on the motherboard. It will work only if  i switch off and on the PSU. So realized that some protection mechanism of the PSU was kicking in. So for testing purpose i used another PSU (Antec HCG 850W Gold)  and also connected both the 8pin and 4 pin CPU power connectors. Now the PC seems stable. I ran a Stability test for 7 hours and it did not crash or reboot. But the following issues persist

1. When i switch on the PSU if i correctly remember, the power and reset switch on the motherboard used to light up. Now it does not, though the other RGB lights on the motherboard come on.

2. When i push the power button the motherboard goes through one power cycle i.e before the motherboard logo comes on the screen the motherboard switches of (stays off for about 3-5 secs) and then automatically reboots and then it boots fine. This happens only if i switch on and off the power supply and happens every time I switch off and on the PSU.

3. When i shutdown the PC from windows, after shutdown the lights of the power and reset button on the motherboard come on. I guess this is the actual and expected behaviour and now if i switch on the PC it boots up without power cycling.

4. If i switch off the PSU and on it again, then the issues mentioned in points 1 and 2 above repeat. And this happens everytime I power off the pSU and switch it on.

 

Question

- Is something wrong with the motherboard ? DO i need to RMA it

- Any ideas on why the power cycle happens whenever i switch off and on the PSU and not when i shutdown and restart my PC from windows.

- How is it that given my configuration a premium Corsair RM 650W PSU cannot handle the load and requires a 850W PSU ? When i look at a PSU Calculator for my config, the load is supposed to be around 450W only.

 

EDIT: Also added a video link to show the problem. At 2 secs mark you can see the issue of the power button and reset button not lighting up. At 22 sec mark you can see the power cycle that happens.

Ok

On gigabyte website its mentioned at least 600w psu for gpu.

Now you have this motherboard x570 amd top notch which required extra power connector an aio and other things which requires power.

So a psu of over 700w at least required.

I have seen in a you tube video the power reset led only lit when on post or bios in windows it not lit off mode.

if it not lit in bios some time It can be due to bios update flash the bios again inside bios option and load default settings in bios then save and exit.

In this video also power button reset button not lit when in standby mode -- this build video at 8.52 timing. may be its inbuilt in motherboard to lit lights or not.

And many peoples used 850w psu with this motherboard build.

just load default bios settings and restart.

just load default bios settings and restart.

 

Thanks for your post. I have done that and more (Cleared BIOS, Reset BIOS setting, Downgraded BIOS, upgraded BIOS). But it does not help. The power and reset buttons are to be on when i on the PSU and should go off after the POST is done. But in my case it does not come on at all when i on the PSU and then there is the power cycling that is happening.

[DSTECH]

Does the digits start when you on the motherboard you have to start with your cpu cabinet power button not motherboard power button.

[Jinu]

Yes the digits start when i start the motherboard and it goes off after the POST screen comes up

Just to update on the issue:

 

I took the motherboard back to the dealer for testing and he tested with a 3600 series processor and there was no power recycle. But the light issue was there. So he tested his CPU 3600 series  on a new Taichi X570 motherboard that he had. On that I noticed that the power and reset light comes on only after the power button is pressed and stays on till the BIOS screen comes or the systems starts to boot and then it switches off. But on my board this was not happening the lights stayed off. 

 

Please note i have tested my CPU and memory config on a Gigabyte X570 master motherboard and it works fine without any issues.

 

But when i put my CPU in the new board  it would not post (d2 error) and then he updated BIOS using BIOS Flashback to version 4.0. Now the new board boots exactly like mine and the same issue repeats including the light behavior and the one time power cycling started. 

 

So what i have summarized is that ASrock x570 Taichi motherboards are useless and not ready for the 5000 series processors. My guess is that the BIOS Flashback process is screwed up and that is what is causing the Light and powercycle issue. 

 

Now there does not seem to be anyway to cleanup the BIOS and bring it back to original state. I tried BIOS reset, BIOS clear button, BIOS clear jumper, even removing the BIOS battery for 12 hours. Nothing works. Issues stays.

Found a partial solution to the problem. Based on advice i tried the upgrde of the BIOS from the first version that supported 5000 series processory and from there upgrading each version of BIOS incrementally. The following was the results of my testing starting from the oldest version of the BIOS that supports 5000 series CPU to the latest version.

3.4  - worked for non XMP profile. Does not allow saving of XMP profile shows D0 error and reboots and then forces the DRAM to auto mode
3.61 - works and seems stable for XMP and Non XMP profile
3.8  - works and seems stable for XMP and Non XMP profile
4.0  - Failed causes a reboot

 

The weird thing is i had tested with version 3.8 before and it had not worked. I guess i had to go through the BIOS upgrade in the right sequence and not jump directly. 

However the light issue has still not resolved, but i dont care about that anymore. At least the power cycling issue is solved. So i guess I will stick with version 3.8 for now.

I just registred to say thanks Jinu.

 

I've just bought a X570 Taichi which I instantly flashed to 4.00 using the flashback function for my 5800X.

 

I had the issue with double booting too and tried some stuff. Without success.

 

I did the 3.40 -> 3.61 -> 3.8 "trick" and now everything's running fine. Still have my RAM on XMP (but tightened the timings a bit) and no annoying double starts happen anymore.

[Pred]

So i've upgraded to the latest Version 4.10 because I wanted to enable resizable BAR on my 3080.

 

And guess what. The power cycle is back again. I've written the Asrock Support in (little) hope for help. If anything helpful will follow I'll share it here.

[Pred]

Asrock support actually helped me a lot! I feel sorry, that I've had "little" hope.

 

They've send me a different Bios. Version 4.18.

 

The problem causing the Power Cycle is because of an option.

 

 Now, it's possible to disable it. No power cycle at my place

Hello guys,

I was facing the exact same problem with bios version 4.00 + 4.10. Double power cycle on boot during POST sequence.

Everything was working fine up until v3.80.

I also contacted ASRock Support like Pred did, and they have said this:

Quote

" Hello,

This extra power cycle was introduced to help detect 2 or 3 specific M.2 SSDs.

More people got confused with this behaviour, so it will be removed from newer BIOS versions and there will be a separate option in BIOS for those that are affected by the M.2 SSD issue (“Force M2_3 to Support NVME SSD”)."

They also provided me with a newer bios version 4.30. There is a newer option under Advanced Tab now as stated previously

(ForceM2_3 to support NVME SSD) which when set to Disabled resolves the issue of double power cycling.

[Pred]

I looked up the official website and 4.30 is available. Gonna get it too now

[tpcs1980]

I just confirmed  about 7 pm central time today that with that with the item " ForceM2_3 to support NVME SSD"  set to "Disabled"   the double powering up deal  is resolved.

 

Now it doesn't matter if i have the breaker switch on the back of my Seasonic tx-850 Titanium rated psu set to closed ( power ready) and power it on  or open ( as in open circuit as in the system won't power on no matter what ) for at least 30 seconds straight until the power and reset buttons on my Asrock x570 taichi mobo's lights go out..and then flip the breaker switch on the psu again back to the closed Circuit position and then power the system on...=   problem resolve.  IT just powers on once and everything just works like it's supposed to.,

 

Pred   on April 9th 2021.   THANK..YOU  MUCH.  xD   I've been using the 5900x cpu and this mobo combo for many months now and always wondered why it auto shut down and then auto powered back on and everything just worked then.  Cheers.
