Issue on new 9800X3D + B850 Build - Need Help Badly!

[Devastator0]

Hi fellow TPU'ers,

I need some desperate assistance in regards to a problem I'm encountering on a system I have just built for a friend. The issue I'm seeing currently is one where when I cold boot the PC, it either won't detect the machine's network devices (both the ethernet & wifi adapter) or alternatively, doesn't recognise any audio devices. When I reboot the PC, it will then detect everything. I have rebooted the machine multiple times and it remembers the devices but when I power the system down then back on again, it'll boot but then either can't see the ethernet or audio devices again. Such an incredibly weird problem that I've never seen before.

Specs:

CPU: Ryzen 7 9800X3D
Mobo: Asus ROG Strix B850-F Gaming Wifi (Running the 1066 BIOS version)
PSU: Seasonic Focus 1000w Gold
RAM: G.Skill Trident Z5 RGB 64GB (2x32GB) F5-6400J3239G32GX2-TZ5RK (RAM was initially running at it's 6400M/T XMP/DOCP profile but I've disabled that and it's just running at the base 4800M/T at the moment)
GPU: AMD Radeon RX 7600 XT + Integrated GPU
SSD1: 1TB Kingston SA2000M81000G (In M2_1 (top) Socket)
SSD2: 4TB Samsung 990 Pro (In M2_2 (2nd down) Socket)
HDD: 4TB Seagate ST4000DM004-2U9104 (Connected to SATA 1 Port)

I've done a full Windows (11) re-install on the machine and ensured that it has all of the latest available drivers but no joy. I've never seen this sort of problem occur in all my years of building PC's and I'm at my wits end on it.

Genuinely would welcome any advice or suggestions of anything I can do to try an resolve this. If any further info is needed, please let me know and I'll do my best to supply

Cheers!

Boot on linux, if there are no issue, check ya windows, driver issue.

Reinstall windows.

So, have already done a Windows re-install as a part of my troubleshooting of this. Haven't tried booting to a Linux live distro yet but I'll give it a go.

Difficult for me to cop that it's either the Windows install or drivers I've installed because I've used all the drivers from Asus (for everything on the mobo) and then AMD's latest drivers for the GPU's). Either way I'll try.

Try bios a bios with agesa 1.2.0.3a Patch A.

Try bios a bios with agesa 1.2.0.3a Patch A.

The first note point on the BIOS on the Asus website says this:

"Updated AGESA to ComboAM5 PI 1.2.0.3e"

So the version of the BIOS I have installed, the latest one, contains that. I assume the "e" version is newer than the "a" version...

 

[Chomiq]

Yeah it's on latest bios.

Rollback, try the older one. V1006 for example.

I had a NIC issue on my b850 two nights ago and the fix seemed really bizarre. The OS was toggling rapidly (sub 1 second) between wlan and Lan so quickly that I had no good connection on either. Even when I wasnt connected to wlan, just having the system see both devices broke it randomly. The fix was to go to device manager > wlan adapter > properties > power settings > turn off system saving power on this device.

Man... asus doesn't let you rollback from the latest bios.

 

[dont whant to set it"']

Man... asus doesn't let you rollback from the latest bios.

What? They messed up again?
On older mbs it works via the hardware bios flash from io back panel via flash and button .

I haven't resorted yet to BIOS flash back on x670e be it via uefi or via flash, so I don't know if on newer models it gets locked in place unless a newer version is in the pipeline to be flashed.

Yeah that sounds a bit different to my issue. In my case, the hardware doesn't even show up in Device Manager as being installed. If I go to View -> Show Hidden Devices, they appear there but yeah, act as though they aren't installed.

I saw that and I think it's the first time I've ever seen something like that for a BIOS in recent times.

Disable all powersavings on the integrated peripherals in the bios and in windows, see if this helps.

Sounds like a bug overly aggro power savings.

I've had a look in the BIOS but I can't see anywhere specific to do with power management of the integrated peripherals. All of the devices are enabled in the BIOS but I see no other options for power management of them. I did try and switch off the options for the Ethernet & Wifi that allows Windows to turn them off to save power but that didn't seem to make a difference. I am strongly suspecting that something is wrong with the 1066 BIOS version the motherboard has but because of what they say, I can't roll back to an old version. Very annoying!

Does the BIOS see the devices before posting windows?
Or Windows doesn't recognize the devices on cold post, but bios sees them?
______
What version of windows? 24H2 or just the bare install?
Does removing any 1 piece of HW make a difference?
Try unplug mouse, cold post.
Unplug HDD 4TB Seagate and cold post.
Unplug the keyboard and cold post ect ect..

Force it enabled through bios for those entry and try replacing the cmos battery

Surely a hardware issue, maybe motherboard faulty or mounting issue. If it was bios or software, everyone with that board would report it.

 

[Devastator0]

So I've done some further testing and messing around with the rig and I'm leaning towards the CPU itself being faulty somehow. Difficult to confirm 100% since I don't have any other AM5 boards or CPU's to test with but I'll note that I'm seeing the machine randomly hanging at boot with the red (CPU) "QLED" light. I removed the CPU cooler and re-seated the CPU and re-installed the cooler (even mounting pressure) but it's still experiencing issues.

Side note for anyone following along, even though on Asus' support page for BIOS version 1066 they say it’s irreversible, you ARE able to roll back. I did it using the BIOS Flashback and it let me do it (my original issues still existed so it's not a BIOS version issue I don't think).

Things I would do if not already done.

Disable the iGPU in the UEFI
Install the latest AMD chipset drivers from their site
If any of the following are installed: Disable armory crate in the UEFI and uninstall it and any other utility apps in windows. I never use the apps for audio or ethernet. No RGB apps, none of that stuff.
If there are any USB devices that use apps uninstall those too.
