B550-F ethernet device crashing under load

[Tryndabeard]

Hi all,

Been having a nightmare with my new build.

• 5800X3D
• ROG STRIX B550-F
• RX 7900 XT
• 2x16gb Corsair DDR4 Vengeance RGB PRO SL Black
• SK hynix Plat P41 2TB m.2
• be quiet! Straight Power 11 Platinum 850 Watt 80+ Platinum

I made another thread a while back trying to figure out issues with this build and it turned out a m.2 was defective. Now though I'm back to thinking the mobo is the issue. What I've seen is that when playing games and/or downloading large quantities of data my ethernet device dies. This then leads to really weird inconsistent issues including:

• Unable to shut down or restart, it sits on the Restarting... screen indefinitely, have to hold down the power button.
• Unable to boot up until switching off at mains for a few minutes
• BIOS errors on start up including:
  • no keyboard found
  • PCI Vendor and Device IDs do not match!
  • USB overcharge detected
  • hard disk read failures
• Booting up and showing mobo splash screen but never progressing
• Powering on but black screen, no peripherals coming online

When the ethernet drops the machine stutters pretty intensely and LatencyMon complains about HDAudBus, ndis, and dxgkrnl primarily

Event viewer shows the ethernet device has encounters some error and then thinks the device has been removed.

Things I've tried:

• SFC, DISM, chkdsk, SFC found some corrupted stuff on the first run but claimed to clean it up and it didn't help
• Disabled all low power / sleep options
• Installed a PCI-e NIC, disabled onboard LAN via BIOS, made things worse if anything
• Cleared CMOS
• One of my SSDs was plugged into the 5th sata port as GPU covered the others, moved it to the 2nd
• Reseated everything
• Numerous driver tweaks, reinstalls, rollbacks etc

Any help greatly appreciated

The LAN in that board is likely to be one of the defective Intel chips, I think, but I've never heard of them borkin' the whole board when they malfunction and since the board is still behaving badly when it is disabled, that suggests the problem is elsewhere (though, BIOS switch doesn't necessarily disable anything in terms of the hardware itself).

I assume you're on a BIOS that fully supports your CPU and have tested the memory?

Believe everything is fully compatible, got all my driver's from Asus directly including the latest bios, 3205. Yes tested memory and CPU a few times without issues. Past two times I've booted the ethernet has died within minutes, not even under load. I've read about the i225-v defects which is why I tried out the pci nic (Intel CT Gigabit) but it's not helped whatsoever.

You might want to consider breadboarding, just to rule out that there's a short somewhere, but I think I'd be starting a dialogue about a RMA.

There is actually a firmware update available for the i225-v Lan controller, it is however on another forum and I'm not sure if I'm allowed to post a link to it, people have reported that it fixes many problems such as drop outs etc, all I can suggest is that you just Google it.

I gave up with the Intel i225-v NIC and disabled it in the BIOS, I now use a USB NIC. Just having the Intel one Enabled stops the USB NIC from working. Hope Intel/ASUS get hit with a class action for this ****.
