ROG Maximus Z790 Hero and Intel i9 13900k very unstable using AI Optimizer. My MC SP score is low

This article notes that an MC SP score under 65 is considered below average. My intel i9 13900k consistently scores between 60 and 64. I have about 3 days left to exchange this CPU before I'm stuck with it.

Is it worth trying to get one that scores better before its too late?

I do not have AI suite III installed in Win 11

Bios settings:

XMP 1

AI Optimizer On

That's all the tweaking I've done but since the CPU is generating a low MC SP score I am concerned.

Unstable and seemingly random crashes. Will crash at idle... Will crash during game play or browsing the web or watching videos, but hasn't crashed once during a Cinebench test or a Heaven Benchmark.

One blue screen code I caught was WatchDog Violation.

Hello, @VL_Sanders 

Could you please confirm your current BIOS version and whether the problems you described still occur with clear CMOS and default BIOS settings?
We have discussions on your topic in ROG Discussions > Overclocking & Tweaking.
I may relocate your post to the proper category if you'd like.

Thank you.

BIOS version newest 1801. System was stable when I load BIOS defaults. However that's all the input I'll be able to give as time was running out on exchanging my CPU, I swapped it out today and discovered 10 minutes ago I have an all new problem.

Returned 13900k and upgraded to the 14900K thought i was doing the right thing. Now the system does absolutely nothing but power up. System doesn't boot and I can't even get to BIOS.  Q_CODE 00

Before I I replaced CPU I reset to default and left the system boot then shut down. After I removed the 13900k and before installing 14900k I thought i re-flashed the bios to 1801 again.

I do not know if there was another step I had to take before changing CPUs but he system is doing nothing but powering on.

Best answer would be to try the 13900K again, but it sounds like you no longer have it. Inspect the socket and ensure there's no damage or debris on the pin pad, then remount the CPU and cooler whilst adhering the cooling vendors mounting instructions.

If no joy, use USBFlashback function whilst ensuring to correctly rename the cap file.

Thank for the advice. I had already tried all that with no luck. Motherboard would not recognize either processor. Since it was a local Best Buy purchase they both went back. I just exchanged the MB and before installing the new processor I updated the BIOS to 1801 and I am up and running with a 14900k with an MC SP of 73.

With any luck I'll be spending some time over in OC and Tweaking!

Cool, glad you managed to resolve. It was always going to be one of the two.
