Global Core SVID voltage.
Best bios for z790 apex encore
www.overclock.net
Follow the google drive link and get bios 9905. Should be better.

Actual VRM core voltage reading above the voltage you wrote seems to be the only reading giving a number. Just wondered if that was vid or Vcore.

If you change Actual VRM core voltage to manual you can then input your desired voltage. I would suggest 1.35 volts. Then test and see if its stable

A few rambling, and certainly not based on experience, thoughts...
You note that you had stability issues with your first BIOS that allowed your CPU to maintain the all core clock of 5.9Ghz.
You flashed an updated BIOS that improved stability BUT will no longer boost to those previous speeds, where it was unstable....
Are your expectations of what you feel the CPU should be running at based on what it can realistically and maintain stability, assuming heat can be managed..?
Genuinely, I do not know anymore where they are up to with the hot melt RL CPU's at the absolute top end in combination with manufacturers settings / Nvidia flipping the lid off the can of worms and Intels less than obligitory recommended settings.
I'll link you to this page of a review of the CPU you are using....
Linky link
and.....
they had to work to get the CPU stable at 5.8Ghz all core overclock.
MCE is going to try and boost all the cores to that of the highest running core, for me that would not be ideal. Then again I would not need that either.
As @Jay85 noted in his other thread, the monitoring software can help.
Even Intel's XTU can offer something to try, over that of the BIOS. But, like I mentioned, I'm not sure what is reasonable to expect from that CPU with the recent events occuring.
If you try XTU then the BIOS should have no enhancements set.
Without MCE do you see the odd, I think 2, cores boosting to 6.2Ghz..?
Good luck.

Don't think it meant to stay at 5900 all core as the PL2 high power setting which is used for boosting to the high clock speeds is time limited to so many seconds
On my Asus Z790 Dark Hero motherboard the default PL2 time limit is 96 seconds (if i remember right)

As MCE tries to boost all cores to the highest core clock it did mean, for me, that my 14700k never got to the highest boost setting for the individual core that it was meant to. Now I've disabled that the cores boost more as they are expected to, well at least what I expect. But that also means seeing certain cores run really low speeds as the OP noted, dependant on work load.
Games tend to illustrate that the most imo.

I just don't trust the latest asus bios for the 14900/13900 cpus as I have a 13900ks and have tryed the new bios and I couldn't set it the way I used to so whent back to 1902,saying this I've never had any instability issues at all.

Just like you said really, I wanted to achieve the similar running of 5.9 all core in games, as I believe it should run.
Yes, with and without MCE it still boosts to 6.2 on 2 cores.

No worries, you are welcome
Achieve the similar running conditions that you had at the start........without the stability issues you had of course.
Should it run at 5.9Ghz all core as per spec as std behaviour..?
Genuine question, not looked at what that CPU is designed to run at when running all core, perhaps more relevant as there seems to be a factor where scaling back some of the unstable settings were applied by some board vendors.
In that linked article they got theirs to run at 5.8Ghz all core as an overclocked setting.

I guess if you look at the 14900ks product page then it does mention boosting to certain clocks under thermal and power conditions so maybe you are right and new bios versions enforce more of this.No worries, you are welcome

The trouble is it was down clocking way more than advertised speeds.
I’ve been continuing to run with MCE enabled. No WHEA errors yet but its runs stupid voltages. It runs above 1.5v in certain games (cyberpunk is a big one for this)
I am still worried on stability though as I am getting crash to desktop in certain games.
Also the load voltage is crazy in that it just seems to go to the highest voltage seen under load in some games rather than the highest voltage being the idle voltage. Hope that makes some sense. I mean that I usually observed that a cpu voltage reduces from max (idle) under load, not go to the max.

Your choice, perhaps poorly worded by me, has illustrated an extreme example of a CPU architecture being pushed to the absolute limits of what it can be ran at, whether stable or not. Thermally it is pushing the envelope on manageability and power wise, kinda linked, it is less than desirable when pushed.
I do not know enough about the board / BIOS combination you are using, nor the Asus features, to understand that by increase the load and core speed there is also a similar increase in vcore voltages, akin to that of LLC settings. So, to try and attain stability at high clock speeds across the cores, additional vcore is being thrown at it, simplified understanding I know.
Have you tried removing all the Asus enhancements, something like Intel BIOS defaults, and then tried XTU to see what that could offer..?

Believing it should run at 5.9 all core is one thing but you might have to accept that it actually is not able to do that due to the limitation of the silicon, or return it if you're unhappy with it if still within time.
When I looked at the 14900KS Intel Spec Page I saw that the "Performance-core Max Turbo Frequency" is 5.7Ghz. The "Intel® Turbo Boost Max Technology 3.0 Frequency" is 5.9Ghz.
I take the former to be what we refer to as the default all core frequency. So really anything above 5.7Ghz all core is not strictly guaranteed. If you read the bumf explaining the 5.9Ghz "Technology 3.0 Frequency" it states.:
Simply by using the phrase "best performing core(s)" would indicate to me it is not a stock all-core frequency. This would explain why in the review that @Vimes linked they only got to 5.8Ghz all core and why you are having similar difficulty.
At the end of the day the 14900KS is on the raggedy edge of what Intel can squeeze out of Raptorlake and in my opinion they are hoodwinking some customers into what they might expect to get out of it.

It depends on the cpu temperature and what voltages are being pumped into it. If your able to lower the vcore you will achieve a better temperature and your system will become more stable. With 2x 360 radiators 5.9ghz all core might be achievable. It will not be achievable with 1.5v as that is too much and the cpu will get too hot and become unstable
