Jay posted a video called "Motherboard Default settings could be COOKING your CPU!" 
 
I tried posting a comment on his video asking about EVGA bios settings on how to fix mine.
 
I have the Classified Z790, and I am getting temps close at 100c during the test he showed in the video, but he only shows 3 other company bios fixes, and I don't know enough about bios settings to try an match them.
 
Can someone help?

I think he was just talking about limiting the max power, which I believe is available in latest BIOS release. I haven't used it, so I can't tell you where it is (possibly advanced tab -> CPU Configuration menu?), but I do remember seeing that. You can just drop the maximum power limit if you want to make sure you're running per intel's stock specification only (or whatever limit you want to apply).

Drop the power to what?

Whatever you want. First of all, you didn't indicate what CPU you have, so I can't even tell you what the stock intel spec is for your CPU. Second, Jay even said he sets it higher than that based on his experience...so it's totally up to you. By default it's maxed out at 4096W. You can change that to ~275W if you're on an air cooler. ~315W if you're on a 360mm AIO, and ~330-368W if you're on custom water loop. All of those are above the intel specification. For example, the default spec for 13900ks is 253W. If you set it there, it will likely not hit maximum P-clock boosts during heavy workloads. So it's always a trade-off.
 
Further, Jay often advises (as would a lot of people) to "undervolt" your CPU to reduce how much power it's drawing. There are a few ways you can do this. Either use voltage override settings and set a fixed voltage that is lower than the CPU would draw as a maximum and it will draw that fixed voltage all the time (sometimes consuming more than normal, but the maximum would be less). You can also put it on adaptive voltage mode and then adjust settings in the V/F points. This is pretty tricky on EVGA motherboards because the BIOS doesn't give you the actual voltage points, it just lets you put mV offsets at several frequencies. So you can put no offset at your highest boost clock, but a negative offset at your all-core boost-clock, which will result in a slight under-volt and reduction in power at the all-core boost point but allow greater stability for the single/dual-core boosts that are to a higher frequency than your all-core. It seems slightly bugged in EVGA BIOS, and we're not getting any updates, so you're basically on your own to trial and error your way through the existing BIOS if you want to try adaptive. I'm currently running that mode, but it's a real pain to get just right with the guessing and checking process and I'm 95% sure you'd have better luck doing V/F points and adaptive voltage control on any other brand's motherboard. EVGA's BIOS team (before they all got fired/left) never really moved past focusing on all-core OC and override settings. They don't have nearly the level of control and optimization available that Asus, ASRock, MSI, and Gigabyte have when it comes to adaptive voltage tuning.

I limited mine CPU power to 253W per Intel spec for 13900KS. Default is Auto and it's set to 4096W.

I updated that limit from 253W --> 320W as Intel i9 13900KS limit is 320W per Intel spec and not 253W
