Could you please elaborate what exactly you mean with "working as intended" because this Intel's article implies, way I am interpreting it, you see this warning when motherboard is NOT working as intended:

"Current Limit Throttling
There can be multiple reasons why the current limit is throttling on the processor. The three common reasons for current limit throttling:

1. Processor Core IccMax is set too low in XTU.
2. VR (voltage regulator) current limit is set too low in BIOS. (Different motherboard OEMs may have different names for this control, so please check with your motherboard vendor.)
3. The motherboard is not able to provide high enough current for the given CPU. Pairing a low power motherboard with a very high Thermal Design Power (TDP) chip can cause current throttling, even with current limits set to the maximum."

So why exactly you claim, please, that seeing this means mb is working as intended?

The first option, however, is unrelated to the motherboard's operation.  This is an option in the XTU software, which is also the software providing you with the notification that you've hit a limit.
 
Our X299 motherboards follow Intel's guidelines for default settings.  We could disable the EDP/current limit in the BIOS at Default, but this is not a good direction to follow.  As to why you're seeing it with your 10900X, you might consider that Intel refreshed CPUs over roughly 3 generations on X299 by using higher ratios, but kept the same power limit each time.  Hitting an EDP/current limit is not difficult under those circumstances.  
 
As noted by the Intel XTU FAQ, I would look to see if you can increase the Processor Core IccMax in XTU, as that would be a software driven solution for this issue seen in XTU. 
 
Regarding item 2, EVGA X299 motherboards follow Intel's default specs; if the current limit is set "too low" for this reason, it's because Intel provided incorrect specs that were too low (I really don't think that's the case, however).  It's only when taking the board off Defaults and configure some overclocking that the X299 DARK begins to automatically handle power limits to make sure you don't throttle, unless you hit temperature limits.  Otherwise, it strictly follows Intel's specifications at default.
 
Regarding item 3, this most certainly isn't an issue with an X299 DARK, which you have; if there is insufficient current being applied, I would try to add a second 8pin EPS power cable if you aren't already doing so; however, this should be unnecessary at stock settings and even overclock settings short of extreme cooling.  As it is, the 8pin EPS connectors are rated up to 40A/480W per connector, or 960W total power available for the CPU.

hello, i have the same issus with my x299 micro 2 and 7800x, regarding hwinfo, the IR35201 can't go higher than 191W input, but when the cpu require more than 192w there is throttle.
at 5ghz its "ok" little throttle (IR35201 in 192w and IR 35201 out 205W) but at 5,1ghz the IR out is at 230-240w and the frequence go to 4,8-4,9ghz because of throttling.
 
I think it's not a motherbooard issus because the micro2 can handle a 18c, it's maybe a cpu security ?

@EVGATech_LeeM Thank you for your reply. I hope seeing it means you are staying safe and doing well.
 
Before we continue discussion, I would like to look at IccMax for my CPU vs. XTU. How one can find exact official IccMax for i9-10900X, please? I can’t find anything that lists it.
 
In the meantime I doubt I am not supplying sufficient power to mb. Both EPS cables are connected, 6-pin for extra PCI power is also connected, and PSU is AX1600i (not that that should make a difference, correct?).
 
P.S. Do -you- experience same throttling with your setup if using same settings as me?

@EVGATech_LeeM I have checked XTU and version I am using (most recent one) doesn't have any setting labeled ICCMAX. There is one called "processor current limit" but I don't know is that same. In any case XTU shows that one is 1023 A at boot, so that wouldn't be it, would it?
 
In any case have you tried looking at this using XTU on your own X299 Dark with your own CPU and what are you getting?
 
I was able to get different person to try this with his own X299 Dark and CPU (I believe Skylake-X) and he was -NOT- getting that throttling warning from XTU.

in hwinfo theres a tab called PMAX Limit/VCCIN Under-Voltage
watch that while load if it hit yes theres not enough vccin.. raise your vccin..
or dissable svid and problem solved..
but, watch for phantom throttling best app for that is cb on a loop

im still waiting on why  cpu is power throttling  on blender using avx when i use voltages bigger than 1.330V. when i managed to suck over 1khw on this micro2 on quick cb runs...

I did some testing on this "Current/EDP Limit Throttling" subject with my X299 Asrock board with a 7820X.  What I found was with all stock BIOS settings with the exception of XMP enabled, the EDP limit would constantly bounce back and forth from throttling to not throttling.  This was just sitting idle at the desktop.
 
In the Windows power options, I was using the high performance profile.  I changed it to balanced and the EDP limit bouncing back and forth was reduced somewhat.  I then tried the power saver profile and it reduced it a bit further, but did not eliminate it.
 
Then I set the high performance profile back, went into the BIOS and changed the VCCIN from "Auto" (1.80v) to an offset adding +20mV.  I rebooted and went back to XTU to monitor the EDP limit again and for 20 minutes so far, not a single throttle.  Again, this is idle at desktop.
 
I should also note that when I overclock the CPU, the VCCIN voltage increases to 1.90v up to a 4.4Ghz OC and above that goes to 2.10v by default.  I saw no EDP throttling while overclocked.
 
Just my 2 cents and testing observations here...

A full 40 minutes into monitoring the EDP limit (XTU) only browsing the EVGA forums and I've had only 2 spikes triggering the throttle limit using the settings mentioned above.  I'm going to up the VCCIN to a +50mV (1.850v) to see if it eliminates the spikes altogether.

Point is that it is reporting throttling when mb is using _default_ values. Raising vccin or whatever ... that is manually changing away from defaults. Regular consumer should be able to purchase mb and not have to change things away from defaults to have it running without any warnings popping up.

bdaryI saw no EDP throttling while overclocked.

I too don't see EDP throttling when CPU ratio is not on auto anymore. According to @EVGATech_LeeM that is because moment you change away from auto limit for it is disabled. This thread is about why we are seeing it when we are at auto defaults.

On mesh CPUs like SKX/CLX there is power management unit inside CPU that handle clock changes. When it switches between one turbo ratio to another it will report EDP/Current clipping while all CPUs are switching ratios. When it's done, this flag goes away. If user set CPU ratio to manual , there is no automatic ratio changes so no EDP clipping is reported. However if user to change ratio in windows, for example using XTU ratio adjustment slider - you can see same thing - EDP/Current limiter will be clipped for few seconds, when all cores switching to new ratio. It's normal and known behavior. You can ask Intel on why this is happening too, perhaps if many users ponder same question, they could remove this item in future :)
