I was running Intel XTU stress test today and “Current/EDP limit throttling” kept coming on, which seems to be same issue described in this thread  https://forums.evga.com/X299-Dark-BIOS-v118-Possible-BugIssue-m2975001.aspx
 
This review http://tellitlikeitisnews.com/the-evga-x299-micro-motherboard-review-a-smaller-take-on-x299/ claims it is caused by BIOS default settings but goes away when overclocked (and benchmarks seem to confirm that).
 
So I went to BIOS, changed frequency multiplier from Auto to Manual Ratio Limit of 43 for all cores and AVX offsets of 0 (which is not overclocking the CPU as it is within specs, it is just not auto anymore) and lo and behold in last 2 hours of XTU I didn’t see that warning come on.
 
What is going on, why setting things manually makes it fine but auto doesn’t even though it should, and when it will be fixed?

Cool GTX
Thanks for sharing your results

You are welcome :) According to post by @EVGATech_LeeM in that other thread I shouldn't be experiencing this issue in my setup yet I am having it. Hopefully I will hear more from him on it soon.

I do have the same issue with BIOS 1.21, I was getting “Current/EDP limit throttling” in the XTU just in the Desktop without any Benchmark or Games!! I did change AUTO to Per Core and no more “Current/EDP limit throttling” some thing is wrong somewhere.. 

Agreed, something seems to be off ...

I have the same issue, and PerCore mode doesn't even work - all cores reduce to 43x on my 10900X regardless of the PerCore settings which include only 47x, 46x, and 45x by default.

I don't know details of what you mean with "all cores reduce to 43x on my 10900X regardless ..." but notice Intel's official "all cores turbo" for this CPU is 4.3 Ghz (= 43x).

We're looking into this.

Thank you!!! Please don't hesitate to let me know if you need any additional details of my settings.

I'm not sure if this helps, But I notice this issue on my Micro ATX 2 setup too, with the latest bios, and with a 7920X CPU... I just thought is was the way it was. Go figure.... I don't think I have the throttle issue, just the pure clock mode reset to 43x. per-core.

Thank you for sharing this info :) According to what LeeM posted in that thread I linked too this issue has been triggered by Intel microcode update and happens only when all 3 certain conditions are in place. My problem is that I am not meeting 2 out of 3 conditions yet it is happening.

PINKTULIP
Easy to blame Intel microcode...........

As I am not an insider I have to give benefit of a doubt to both sides.

EVGA / @EVGATech_LeeM any updates, please?

Again, my apologies for taking a long time to answer this.  

Our MB/BIOS teams looked into what you're seeing, and it falls under "working as intended".  EDP/Current limit throttling looks like the CPU default behavior when following Intel's guidelines.
 
When you switch it to "Manual" mode, our X299 BIOS will auto-adjust some overclocking settings.  This is why you'll see a difference between Auto and Manual.

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:
 
https://www.intel.com/content/www/us/en/support/articles/000039154/processors/intel-core-processors.html
 
To quote them:
 
"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.

@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?

ZoranC
@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...

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.

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.
