Question On my third i9 13900k - I've just upgraded my BIOS to the 0x12B patch. Would this be enough to fix the degrading CPUs?

I'm asking this because a couple of people online are saying that 0x12B patch isn't enough and you need to manually undervolt/change some settings in the BIOS. To be frank, all of that sounded a bit too technical for me, so I'd rather not mess around in the BIOS settings and brick my PC.

Update your post to include full system hardware specs and OS information.

Include PSU: make, mode, watttage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

Attached peripherals?

Primary use of PC?

What are the qualifications of "a couple of people" ??
How do they compare to the qualifications of Intel engineers.
Conspiracy theorists say you can't trust Intel.
But.. then who can you trust?

I've read how it is a voltage issue, and even after the BIOS update the voltage was exceeding the safe limit. So I got a little paranoid.

It's going to depend on your motherboard because the AC DC LL values on "Intel defaults" with every BIOS update seems to change causing different voltage ranges on CPUs. You're going to have to bench the CPU under the new BIOS to see if it's affected the performance or not. Personally on a MSI board, when I look at the launch BIOSs, "Intel Default" used to be LLC Mode 8, now they are Mode 16 on 0x129. Which means the voltages are up about a good 80mv or so across the board. So this required me to manually change it down to a lower mode to get the old voltage curves and claw back some of that lost performance.

Thanks, I did upgrade to the F12 bios the moment I got the new CPU and put the "Intel Default Setting" to Performance. After this I should be good right?

Also I've another question - I cannot disable "Multicore Enhancement" in BIOS if the Intel Default Settings are chosen. Should I temporarily disable it, disable the Multicore Enhancement option and turn the Intel setting back on again? Or does the Intel Setting override it?

 

[geofelt]

I can not answer your question with authority.

I would leave the Intel default settings as is.
As I understand "Multicore Enhancement" it will allow clock boosts on all cores when needed and possible.
That is good for performance.
