Hi, almost month ago i contacted evga  about having a "custom" fully unlocked bios which means i can access "hidden" settings or lets  settings that are accessible only via aptio v utilities  which is not commercial and easy to get tool and its time consuming because in order to change you values you need to mess with command prompt to export the settings, then manually edit everything in notepad , export the settings in command prompt again and then restart the pc. Thing im messing with are not even overclocking stuff or anything that could permanently damage my pc settings most of them are related to pci-e performance and sleeping features and long story short its just my personal experiment with different settings influcing input latency and pci-e jitter, but the thats not that important part. I guess im doomed to use text editor  even if its matter of 15 minutes for technician to make the settings accessible for 'user' , export it , zip it and send it to attachment. The main problem is the are two available bioses 1.09 and 1.08 on this motherboard and on both them my vcore is greyed out locked on auto pumping my vcore to 1.45 to 1.475 v on my 5800x3d sucessfully raising the idle voltages to like 60-65c with noctua nh-d15 cooler , just no way to access this settings and lower the voltages, lowering llc does nothing. Same goes for multiplier which is shady but somehow understandable considering the fact that this chip is not overclockable and overclocking it can bring fatal results but for god sake can you please make a new version of bios so i can lower the voltage? Its ridiculous.
Another funky thing is that after two weeks of not having an answer from support i've checked the mail and under my latest send message there was a little warning with small font telling me that e-mail was not send, so i send another one and immediately i've got response from mail deamon that my message was blocked with it's answer "550 permanent failure for one or more recipients (supporteu@evga.com:blocked)" so right now im very confused i spoke with polite way , not being arrogant or something but this for me seems to be me being on blacklist. So i am here, waiting anyone on from evga to answer on this. 

same issue on your second BIOS?

same issue on second bios. am i missing something, is there any jumper to be unlocked ? both bioses have vcore grayed out. could be this simply faulty motherboard?, i have no issues inside windows except too high voltage. link you provided is 404 for me.

 
re link, Contact Info
 
 
Just mentioning that MB has multiple BIOS, selected by a switch.  My though was the BIOS you were using might have been corrupted.
 
As I do not own that MB to look at, it was just a guess - something easy to check

Nope, i just tried all versions 1.07, 1.08, 1.09 , multiplier and vcore is locked, no way to point at them. Had no problem at x570 dark hero viii.
 
 

 
Found this with a web search The EVGA X570 Dark Motherboard Review: A Dark Beast For Ryzen
 
Article photos, seem to indicate you should have the ability to make changes - (under OC or EXTRAS tab) - so it might depend on Where you are in the BIOS.
 
Is this where your looking to make the change? Open "Advanced Configuration" then look under either "OC" or the  "Extras tab"
 
(excerpt from link above)
 "Plugging in the inclusive USB drive and clicking on the executable file brings up a list of options. These allow users to install essential drivers, including AMD's RAID software, with other possibilities, including EVGA's ELEET X1 overclocking utility,
 
 
What about the "OC Robot"? - does the voltage change/ let you make changes?

No luck here :(, enabling l2n mode for does nothing. I guess the board is faulty. Is there any place i can claim an warranty in europe? I dont really want to send it back to usa.
So if there is no jumper (slow mode switch turned off) is there something wrong connected that could cause such a issue?

Yes, I believe Warranty can be completed in the area of the World where you actually live (not restricted to where purchased)

How To RMA

sorry for late answer. I can see you have the same cpu and board, is your vcore option greyed out too?. Its kinda weird because before i bought motherboard i had asus rog crosshair viii and  vcore settings was adjustable but somehow on this board its locked from eldest bios version and it makes me angry. Also good u mentioned curve optimizer because its also not present in bios or in other words its not visible in bios  but according to exported bios settings which i did via AMISCE utility , it's there, i can see it in text file that containts it , i can manipulate it from there but i cant see it in bios which is again ridiculous for that kind of motherboard. Also the motherboard is very much capable of LN2 overclock so hypothetically lets say im xtreme oc enthusiast (which im not) and wanna try 5800x3d limits and oc capability under controled enviroment (which i dont) but hey guess what , the most basic setting is locked but its not on 300euro cheaper motherboard. Iam really dissapointed from this buy no matter how good this motherboard is from technical point of view (i love closures, speaking about technical point of view i cant have my studio monitors on while gaming because i get gpu interference streamed into them which again wasnt the case on crosshair viii)  the bios is just one big mess. Also why there is no settings in chipset column, i get it , the board is made for oc enthusiasts that dont mess with chipset or any other non-oc related settings but some people do. Evga support (when i was able to communicate them before they blocked me for probably wanting too much)  told me that i need to register my product and they will contact technician for my custom bios request that how i mentioned was bios that has every setting visible because editing things from os is time compsuming and i cant hex the file because iam not at that level.  few days later the answer was "we dont have any bios like this" like iam requesting something that is not on stock lol when in reallity all it takes for technician to either request that kind of bios directly from AMI which i tried to contact but they wouldn't bother to answer me back OR he have utility to makes changes himself but he dont want to do that for unknown reason. So right now i overpaid 400 euros (including fee and transportation cost) when i sold my rog crosshair viii for this and i cant even setup curve optimizier, i cant adjust my vcore, the basic chipset settings are missing and my chip is running hot thanks for this shi*ty bios and the cherry on top of the cake is  when i try to reply and continue in conversation with evga support i get answer from google mailer deamon that says my message was blocked and i wasnt rude to them in any way. Really awesome buy evga, worthfull upgrade,  thanks for experience :-) 

Thanks for your reply, atm im not saying anything new but i could lower voltage at asus crosshair viii atleast and i'm using pbo2 tuner and i was using it on previous motherboard which allowed me to decrease a temperatures more with voltage adjustments.  Memory oc is not such a thing for me on  5800x3d and iam even considering to switch from 16gb 3600 16-16-16-32 to 32 gb to 3600 16-18-(higher) because many tests clearly shows that there is very little performance increase with that amount of l3 cache . Can't you just open/unlock the settings from current version of bios? 

absolutely ridiculous board. i just need one month so i can FINALLY get rid of it / iam  upgrading to am5 with actually working MSI board i've rather 8 layer pcb board with components with little worse quallity.. I've unlocked settings i wanted because apparently "intel bios team" is too busy to do simple thing , but now iam dealing with 'deviceid' problem so now after the flash iam getting 5 beeps indicating problem with gpu ( yes , even the two bioses that was working and didnt touch them). I did a little googling that indicades its deviceid problem, i did the nvidia firmware update which gave me  quote "already latest" but it still didnt help, different ports didnt help, display port didnt help, so i had to buy cheap gt440 and use my 15 years old monitor to actually access  bios. I had zero problem on previous asus board with this gpu and also considering fact that update utility is telling me it have latest firmware im not blaming nvidia for this. Awesome experience with evga board, technical quallity wont save this. U can lock this thread, im done with this board.
