Hi Wino,
I just wanted to let you know that ASRock sent me a modified version of the latest UEFI (they named the file V10.50A) and it has solved the issue on my motherboard. Now the CHA_FAN1 header works properly in PWM mode, and I measured 12 volts on the second pin of this header. The other fan headers also work fine.

Let me know if you want me to send this file to you, or you can ask it directly to ASRock.]]> Tue, 05 May 2026 02:00:09 +0000 https://forum.asrock.com/forum_posts.asp?TID=113500&PID=201372&title=ab350-gaming-itx-cha-fan1-not-working#201372 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=201368&title=b850-pro-a-unstable-post-issues#201368 Author: CantDoScheisse

i bought the B850 PRO RS and 9900x combo the 04.29.25 and had no issues, until recently, followed steps from this forum, and reddit, other forums. Red & Orange light not budging at all.
The motherboard killed the cpu.
Luckily i had a pal with the same chipset AM5, Msi Edge ITX and my cpu gave the same error, cleared cmos, let it run for 30min+. put his 9800x3d back and no issues.
In summary. RMA everything and get something else rather than Asrock for now.]]> Mon, 04 May 2026 05:29:59 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=201368&title=b850-pro-a-unstable-post-issues#201368 https://forum.asrock.com/forum_posts.asp?TID=113474&PID=201367&title=b450-gaming-k4-usbc-3-1-port-issue#201367 Author: Xaltar

Hi, as I am still responsible for an answer in this thread:

I acquired a nice A-to-C cable fitting the required specs, as tested on another laptop.

Unfortunately, both the A and the C port on the ASRock Board do not deliver up to their promise. UBS2.0 is delivered, but 3.whatever is not functional.

I got a PCIe Card second hand that is working fine (Delock 90161, unfortunately the DP-Passthrough does not work...), so it doesn't seem that software etc is in the way of it working someway.

Just as an end to the story :) the board is several years old at this point, and works fine otherwise, so I don't plan to open any support ticket with ASRock.]]> Sun, 03 May 2026 23:46:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=113474&PID=201366&title=b450-gaming-k4-usbc-3-1-port-issue#201366 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201365&title=x870e-nova-d4-on-restart-cold-boot#201365 Author: dom0xDee4

Yeah, all components bought in December 2025 (case is old model), Samsung NVME Gen5 bought in April 2026 - which is when i took other components out of their boxes and assembled everything - basically i'm fighting 4d ever since one of first cold boots this mobo / cpu / memory combo had in it's electronic life :)

I'm just unsure, given how it goes thru stress test - that nothing really is "broken". Think i should've chose better when i ordered memory.

Something i don't think i mentioned too often before: it wakes up from standby happily, not even once has that failed fwiw.

But evidence on different BIOS versions behaving differently kinda defeats "defect hardware" theory - i'd bet my money it's something in memory training subroutine - stress tests so far prove once it's over that hurdle, it....runs without hiccups.
Except the "hurdle" seems to be a moving target on occasion.

I did have it in various ambient temps, ranges it had seen is 18°C to 25°C - it made no difference, 4d pops-up when it feels like so :D]]> Sun, 03 May 2026 04:52:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201365&title=x870e-nova-d4-on-restart-cold-boot#201365 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201364&title=x870e-nova-d4-on-restart-cold-boot#201364 Author: Xaltar

Not a bad way to go really, so long as you are still within your warranty just
use it. If something dies you can get it replaced (for certain) under warranty.
If the symptoms worsen just RMA the CPU and/or motherboard. Odds are pretty high
that a BIOS update might resolve the issue sometime soon.

Thanks again for all your detailed info. ]]> Sat, 02 May 2026 23:49:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201364&title=x870e-nova-d4-on-restart-cold-boot#201364 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201363&title=x870e-nova-d4-on-restart-cold-boot#201363 Author: dom0xDee4

I can't edit the post, but last two shots in BIOS what is different from default:

- default settings shown on the right (arrow pointing to those)
- settings used in y-cruncher session on the left of arrow.]]> Sat, 02 May 2026 21:06:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201363&title=x870e-nova-d4-on-restart-cold-boot#201363 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201362&title=x870e-nova-d4-on-restart-cold-boot#201362 Author: dom0xDee4

Alright, posting some now.

So currently am running XMP-1 (which for my kit is 5600 MHz, 1.25V).
When i choose "XMP-1" -> BIOS automatically changes alot of settings, all of which you will see listed on photo i have taken.

After selecting XMP-1 -> ONLY ONE setting i have manually changed from what BIOS auto-configured: Processor ODT Impedance (in OC Tweaker UI - i still wonder and have a question if you can get such info, at which point during boot process OC-Tweaker UI settings become effective).

After that, i have restarted it couple times, did one or two shutdowns - not unusal, it booted WITHOUT 4d code - but as has been proven before that tells nothing.

Yesterday i ran few shorted sessions of y-cruncher (one hour each roughly).

Today it ran for OVER 5 hours, as you will see from screenshots.

Let's begin.

Y-cruncher start page, system info, test


Y-cruncher start, tests listed (running all of tests provided by Zen5 binary)


Y-cruncher mid session shot, with HW Info on a side


Y-cruncher mid session shot, with HW Info Memory and PSU data in focus


Y-cruncher mid session shot, with HW Info CPU and MBO data in focus


Y-cruncher doing memory-intensive VT3 test, task manager shot (memory usage, cpu)


Memory temperature in focus, during VT3 test


Y-Cruncher clocking over 5 hours, no error whatsoever


BIOS Home page, basic data:


BIOS OC Tweaker page:


BIOS DRAM XMP-1 and Timings part1 (automatically loaded after selecting XMP1 profile)


BIOS DRAM XMP-1 and Timings part2 (automatically loaded after selecting XMP1 profile)


BIOS OC Tweaker DRAM Bus configuration. ONLY manually altered setting, following the selection of XMP-1 profile (BIOS changes Processor ODT Impedance to 53.3 ohm, i manually selected 43.3).


BIOS settings which differ from default - used a neat trick here - "Restore default settings, then chose "Save and exit" -> which lists all changes. (don't forget to discard if anyone uses this trick). Makes a handy list :)

pt1:


pt2:


As you can see, once powered on - the system seems rock-solid. IF it passes thru dreaded memory training. Is something at fault? Maybe, but what if i happen to send any component for RMA - i'd probably get it back with a note "nothing wrong, passes all tests"...

To me it seems like something in the training subroutine needs more work.
BIOS v4.2 did improve on things - i will keep an eye on it and will start using this machine and see how it behaves in real-world scenario.]]> Sat, 02 May 2026 21:03:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=113496&PID=201362&title=x870e-nova-d4-on-restart-cold-boot#201362 https://forum.asrock.com/forum_posts.asp?TID=113502&PID=201360&title=x670-pro-rs-bios-wont-update-to-4-10#201360 Author: Xaltar

I am afraid there is nothing more I can suggest, you will need to open a support
ticket with ASRock and ask for their assistance:
http://tw.asrock.com/events/tsd.asp

I double checked the link to 4.10 for your board and it's correct (sometimes they
can link to another board model by mistake). I haven't seen any other reports about
4.10 failing to apply on your board so I don't know what the issue could be.

Good luck and let me know how it goes with ASRock.]]> Sat, 02 May 2026 14:39:04 +0000 https://forum.asrock.com/forum_posts.asp?TID=113502&PID=201360&title=x670-pro-rs-bios-wont-update-to-4-10#201360 https://forum.asrock.com/forum_posts.asp?TID=113502&PID=201356&title=x670-pro-rs-bios-wont-update-to-4-10#201356 Author: balu

Hello and thank you,

Yes, I did it exactly as you described.

I can see that the USB LED/ Fallback LED is working for a few seconds and then the fallback LED stays on

When I use BIOS Flash, it reboots, then the lock screen appears for a few seconds, and then it boots back into the BIOS.

I tried an older BIOS version 3.4 works without any issues. But even with an older BIOS, I can?™t get to 4.1.

Current BIOS: 3.5]]> Sat, 02 May 2026 03:26:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=113502&PID=201356&title=x670-pro-rs-bios-wont-update-to-4-10#201356
