Cool GTXThanks for sharing your results
ZoranCI 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?

I did change AUTO to Per Core and no more “Current/EDP limit throttling” some thing is wrong somewhere..
MonstieurI 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.
EVGATech_LeeMWe're looking into this.
mkimbroZoranC 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.

My problem is that I am not meeting 2 out of 3 conditions yet it is happening.
PINKTULIPEasy to blame Intel microcode...........

zGunBLADEzi have a question as well why the micro2 is power throttling with avx after the 1.330v mark?? even when vrms are well cooled?? it also happens when i disable cores and disable ht from bios and uses less power draw only when i go above this 1.330v setting?it dont throttle when im looping cinebench or running other aplications over and over but it will throttle "drops multiplier in some cores" on a loop in blender what gives ?
EVGATech_LeeMOur 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.

Also, which CPU?
ZoranC 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 ThrottlingThere can be multiple reasons why the current limit is throttling on the processor. The three common reasons for current limit throttling:Processor Core IccMax is set too low in XTU.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.)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?

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.
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.
zGunBLADEzin hwinfo theres a tab called PMAX Limit/VCCIN Under-Voltagewatch that while load if it hit yes theres not enough vccin.. raise your vccin..or dissable svid and problem solved..
bdaryI saw no EDP throttling while overclocked.
