Z890 Maximus Hero random micro freezes

[Nimce]

Hi,

I’m using a Z890 Maximus Hero motherboard with the following setup:

• Intel Ultra 9 285k (stock settings)
• Corsair Vengeance 2x16GB DDR5 6400MHz (CMK32GX5M2B6400Z32, running on XMP profile)
• Samsung 990 PRO NVMe M.2 2280 2TB SSD
• Asus ROG STRIX RTX 4080 SUPER 16GB GDDR6X OC Edition
• Corsair RM1000x 1000W Gold
• Windows 10 Pro

I’ve ensured that the BIOS, drivers, and Windows updates are all up to date.

However, I’m experiencing occasional random freezes that last a few seconds before the system resumes normal operation.

Has anyone encountered a similar issue and found a solution?

Thanks!

I have an Asus Maximus Z890 Extreme. I had similar freezing and momentary disconnection of USB ports, to which I have a dozen or so devices permanently connected. There were no BSODs or system hangs. My power supply is a Seasonic Prime Titanum Ultra 850W. I had to buy an additional third PSU 8Pin -> PCI-EX 8pin cable. The problem has ceased to exist for now. If you do not have three PSU -> Motherboard 8 Pin cables powered on your board - do it. If you have three 8-pin cables connected - think again.

Possible migration to Win 11 24H2, because the system works flawlessly for me with the latest bios and Windows 11 24H2 December Edition. This is a recently released motherboard, you should also consider adapting to the latest Microsoft system, not to Windows 10

I haven't seen any "micro freezes" on my board.

Using Windows 10, there are some drivers missing from the support site, such as Wireless, Audio, and Thunderbolt.

I am guessing the Neural processor will not function, but not sure.

You might try, putting the command below in a run box and execute.  Check the graph and see if it shows any repeating problems.

The 3rd power connector was indeed not connected! I connected it and so far looks good, but I'll give it a few days of testing just to be sure and will post an update, thanks a lot for the heads up!

If anyone else has encountered this issue please reply as well 🙂

I'm using Strix z890-f and having similar issues. Random freeze for usb devices (mouse/keyboard) for few seconds. I don't have any 3rd 8-pin connector on my board.

Just had another really small freeze but I suspect it's because a faulty USB Hub I'm using (it was misdetected on the device manager), so I stopped using it.

Also a BIOS update was just released and I updated the BIOS.

@sohanzaman 

What is your CPU? RAM? PSU? OS? updated all drivers and installed latest BIOS?

[sohanzaman]

I used both wired & wireless mouse, tired different USB ports, power management like High performance, Turbo, Power saving. I encounter this issue on any mode, any device. Armoury Crate shows every drivers are up to date. Running Win 11 23H2.

It's a new build. Having those random micro freezes since beginning. Update BIOS about a couple of weeks ago, still see this issue at random times (not more than 2-3 times per day). My config:

Intel Core Ultra 9 285K
Rog Strix z890-F Gaming Wifi (Bios ver: 1101)
Ram: Team T-Force delta 7000Mhz 16GB x 2 (XMP enabled)
Psu: ASUS TUF Gaming 1200G 1200W 80 Plus Gold

Edit: Just noticed BIOS update 1203 was released few days ago. I'll try the update before next weekend & share updates here.

A brief micro freeze just occurred, but its frequency has significantly decreased overall.

I'll try to disable CPU C-States and report back with any news, others - please continue to report if you encounter the same issue as well.

@sohanzaman Please let us know if the BIOS update helped you.

Not getting the micro freeze anymore after bios update, at least so far. I think it stopped for me from 1101 bios update. I just updated to that version a couple of days before I posted my last reply here.
