z790 ProArt Creator motherboard, AI overclocking

Level 8


I purchased this motherboard at the end of October 2023 with a i9 14900kf processor, Corsair H150i Elite Capellix  AIO, Corsair RAM.

Since building the new system I have always had AI overclocking enabled and never had an issue. A week ago Windows would continually blue screen, many different errors but the most common error was page fault in nonpaged area.

I stress tested the memory for 24 hours, no issues. Removed the graphics card thinking this could be an issue (MSI RTX 4090 Suprim X) tested with a GTX 1050ti that requires no external PSU to make sure it was not psu stress related. The crashes would still occur and were becoming more frequent.

Eventually my Windows installation was corrupt, and no built in Windows image repair tools would pass without errors. Reinstalling Windows 11 resulted in the same crashes. I then expected a faulty boot ssd. Installed Windows on a new ssd, same issues.

I then tired Windows 10, the pc was more stable, which was confusing.

Reset the bios, still crashes, installed latest bios still crashes. I then set the cores to Auto or Sync all cores, and now there are no longer crashes.

So, after a long run around and an even longer forum post the issue seems to be AI overclocking related.

Why after 6 months would the system now be unstable? I also run the voltages at Intel defaults, and the temps have never become excessive.

Has the cpu degraded?

The PSU installed is a Corsair H1200i

Hi @PurSpyk,

There are many reasons for a system to become unstable.

1.  Besides simply enabling AI OC, is XMP also enabled?

2. Are you setting SVID Behaviour to Trained?

3. Within the AI Features menu, inspect the recommended Adaptive Voltage setting.

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090


1) XMP is not enabled

2) This is set to Intel fails Safe, was originally on the default setting

3) They are now the Intel defaults, but were the Asus recommendations before

My concern is odd instabilities with no changes until I did the troubleshooting.

Edge would also continually crash with access violation errors and access breakpoint errors.
