Z690-A D4 potential BIOS bug (Intel Default Settings)

[MurdocNicalls]

On my ROG Strix Z690-A Gaming Wifi D4 motherboard with BIOS 3603 when using "Intel Default Settings", "SVID Behaviour" defaults to "Intel's Fail Safe". As you can think, this results in very high voltages and temps. I don't know if this a bug or an intentional choice. Sadly I couldn't find a lot of useful feedback in terms of the new Intel Default Settings for BIOS 3603, 2301 & 1301. But I did find some information, sometimes with images or videos and there the default setting for SVID Behaviour when using Intel Default Settings was always "Auto".

I have a 13700k (SP Score 100 if that's important) and my usual settings in terms of CPU were always Auto with MCE disabled. That results in a 29-30k score in Cinebench R23, temps around 80-85°C.

With BIOS 3603 and Intel Default Settings the score is around the same but temps are instantly 100°C as expected with the way higher voltages. I tried changing SVID Behaviour manually to Auto but that destroys performance completely, around 16-17k in R23. I think it's because of CEP in this case, but I don't have enough knowledge about it so I'm not sure.

I even did a CMOS reset to make sure "Intel Default Settings" really defaults to Intel's Fail Safe and that was still the case.
So again, bug or intentional choice?

Check your AC and DC loadline values with hwinfo64. It could be that they are different and then with the Intel default profiles it leads to CEP intervening and crushing performance. I have an Asus Prime Z790P motherboard and the Intel default profiles are bugged. First of all they set as you said Intel fail safe SVID which is unnecessary. They also set AC and DC loadline values at 0.5 and 1.0, while Intel recommends those values to be equal. This leads to CEP impacting performance. So for now I had to disable CEP in the BIOS to restore performance, hoping that they will solve this in the next update.

In my case both are set to 1.1, sorry about the edit I did mixed up my screenshots.

Hi. How can I find this recommendation ("IA Domain Loadline (AC/DC)") from Intel?

And can someone with 13700k/14700k check what your “IA Domain Loadline (AC/DC)” value with "ASUS Advanced OC Profile" mode and with "Intel Default Settings"? On my old firmware, before "Performance Preferences" I had "0.400 / 1.100 mOhm".

Hi,
Can you check what the VRM loadline is at Intel Defaults?

[MurdocNicalls]

Sure, it was set to "Auto" (Level 3), same with the ASUS Advanced OC Profile.

[IlCode85]

Then your BIOS has exactly the same bug as mine, my BIOS also sets the LLC at Level 3 for both Intel and Asus profiles, on top of the AC and DC values being too different from each other.

I edited my post above because I mixed up my screenshots, sorry about that. With Intel Default Settings both values are set to 1.1. 
But LLC Level and SVID Behaviour are the same as yours.

I have the same board and every bios above 2802 uses more voltage less performance and more heat and the system feels slower overall.

I am sticking with 2802.

I have tried multiple times with these newer bios's and I don't know what's going on but something isn't right with them.

Oh believe me man, the 13th and 14th generation gave Intel a huge headache. All they had to do was a processor like every year, but this time they messed up and now our motherboards are dying. I can see 80 degrees and above in Warzone and the connection cable of the processor is really ah yes That place is truly hell, I hope the latest bios update will fix everything because I can't tolerate it anymore, even though I use it on the Intel Baseline profile, I still can't stop it from overheating, ****** it.
