    Ryzen Master EDC at 100%?

    noxenvon

      I've recently made a new build with a 2700x, it's not overclocked, everything (CPU, GPU, RAM) is running at stock speeds. My question is; why does Ryzen Master software show the EDC, whatever that is, at 99-100% at idle? What is EDC, is it dangerously high for my system, can I change it? I've tried google searched on this topic but there's little to no -entry level- explainations. Threads and reddit posts have gone into such extreme details referring to VRM's and other techno jumble I don't quite understand just yet. I'm very new to the enthusiast PC scene, so any help would be greatly appreciated.

          noxenvon, I am with you and trying to determine what EDC means.  I installed Ryzen Master to see what it says about my system but cannot find EDC, so far.  Apparently there are two; CPU and SOC.  Which are you looking at? Here are my specifications, please post your equivalent:

          ASRock Fatal1ty X399 Pro Gaming, Threadripper 1950X, 2xSamsung SSD 960 EVO RAID, 1TB &

          500 GB WD Black, G.SKILL [Flare X (for AMD)] F4-3200C14Q-32GFX, Windows 10 x64 Pro,

          Enermx Platimax 850, Enermx Liqtech TR4 CPU Cooler, Radeon RX580, BIOS 2.0

           

          Got to run, check later.  Enjoy, John.

              Here is what I have on my Ryzen Master screen, I'm looking at the EDC (CPU) option, second from last.

              Imgur: The magic of the Internet

               

              My specs;

              Ryzen 2700x

              MSI x470 Gaming Plus

              240GB M.2 WD SSD, with 2TB HDD Storage.

              2x8GB Corsair Vengeance LPX @ 2666MHz

              Corsair H100i V2 CPU Cooler

              GeForce GTX 1080 Gaming X

              Win10 x64 Pro

               

              EDIT: I've found that changing the Windows power plan options from the Balanced for Ryzen CPU to the standard Windows Balanced plan takes the EDC down between 20-30% at idle, and 95-100% at load though in doing that, my core clocks fluccuate sporadically from 2.2GHz to 4.5GHz

                  noxenvon, thanks much for the screenshot, good idea.  Here's mine:

                  MyRyzenMaster.jpg

                  It is quite different from yours and no EDC(CPU).  You also have several other quantities that I do not.  Somehow you have selected Core 1 and don't seem to be able to do that.  I will continue to investigate and let you know what I learn.  Thanks and enjoy, John.

                   

                  EDIT: Found this in the Ryzen Master manual:

                  "DC Current (amps) and Power (Watts) reported for Ryzen 2000 Series CPU and APU processors"

                  I suspect the EDC and other settings you are seeing at only available for the 2000 Series and not my 1950X.

                    This Reddit thread well clear up what EDC means in Ryzen Master for AMD 2xxx series CPUs : https://www.reddit.com/r/Amd/comments/8mj9t6/capping_edc_according_to_ryzen_master_what_is/

                     

                    Someone here at AMD Forum might be able to explain to you reading the Reddit Thread what and how to configure the EDC in Master Ryzen in simpler terms.

                        "You are just maxing the current the vrm is designed to safely handle." So going by this from the reddit thread, it's not something to be worried about unless I'm pushing it past the 100% mark?

                         

                        I'm not really bothered about configurations and the likes, I just wanted to know if it's safe or if it's potentially dangerous to be at a constant 100% level. I like the mobo for sure, but I'm more concerned with what could happen to other parts if these VRM things overheat/short out.

                         

                        EDIT: After some more digging and investigation, I have found the culprit of the 100% EDC levels. My PC's power plan was set to the Ryzen Balanced plan, and the minimum processor state was set to 90%. Changing the values on that option has since decreased the EDC levels when at idle. I don't think my processor needs to be using 90% power draw as a minimum, realistically speaking.

                         

                        Thanks to all of the replies for helping.

                            noxenvon, make sure that both the 4-pin and 8-pin CPU power connectors are secure.  I always run the Ryzen™ Balanced power plan, but my processor does not have Precision Boost.  The Ryzen Master Manual has a definition  of some of the terms including EDC.  Providing more cooling  to the VRM may well help.  I would suggest a small fan directed right at the VMR.  I would also suggest you open a Support Ticket with MSI asking for an explanation.  Enjoy, John.

                                Unfortunately I don’t have a spare 4pin connector for my motherboard at the moment, I’m currently only using the 8-Pin connection which I’m lead to believe is still viable, just I can’t access additional features on the CPU.

                                 

                                As for fans on/above the VRM’s, my case is a Mastercase Pro 5, with the top 2 fan slots being used as exhaust for my H100i water cooler and the front 2 being used as intakes. I’ve got one fan slot on the back also acting as exhaust, could that be flipped to act as intake to cool VRM’s?

                                    what is the Make & Model of your motherboard and PSU?

                                     

                                    I will try and see if there is an adapter or separate 4 pin PSU cable you can use to connect the 4 pin connector on your motherboard.

                                     

                                    Here are some cable that you may want to purchase if applicable to your PSU: Amazon.com: ATX P4 4-pin 12V Power Connector to Molex Cable Adapter: Computers & Accessories

                                        It’s an MSI x470 Gaming Plus Motherboard. I’m also running a Corsair CM750 80+ Gold PSU, so I could use modular parts to connect the 4-pin.

                                            noxenvon, your power supply should be fine and yes dig out a 4-pin modular cable, make sure it is CPU and not PCIe and plug it in.  Let us hear.  Thanks and enjoy, John.

                                              According to this website: https://linustechtips.com/main/topic/922473-ryzen-x470-mb-84-pin-power/  you really don't need the 4 pin CPU Power connected. It mentions just the 8 Pin CPU Power connector will be enough for heavy usage. But, with Ryzen, it may be best to connect the 4 pin CPU Power connector to prevent any unforeseen issues in the future. But it is not something vital to connect.

                                               

                                              Copied from a comment from above link concerning the 4 pin CPU Power connector:

                                              The 4 pin is optional.

                                               

                                              Through a 8 pin connector you can give up to around 300-350 watts to the VRM (then circuit which powers the processor).  A Ryzen 8 core processor will peak at around 150-175 watts, and maybe have brief moments - like milliseconds- when it uses up to 200 watts.... so nowhere close to the maximum possible.

                                               

                                              The 4 pin connector is there more or less in case someone would want to use the motherboard to do some extreme overclocking, with very high voltages and LN2 or other super cold liquids.

                                               

                                              For regular usage, adding an extra power cable in the 4 pin connector wouldn't make any difference.

                                               

                                              Check the box where the PSU came in. If it is modular you should have the 4 pin atx connector in the box. My Corsair came with various extra types of modular cables, many were spares and others for connecting the GPU power and motherboard power. I needed a GPU 8 pin power connector but my PSU didn't have one. Purchased an adapter and was able to use a Molex connector to connect my GPU card power.

                                               

                                              I didn't have a need to replace my PSU with a new PSU because my PSU didn't have a 8 pin GPU power connector. If your PSU is High Quality (which the one you have is ) it should and can easily use an adapter cable if you don't have one in your PSU box.

                                               

                                              Since you didn't mention what type of PSU you had, I was assuming it was an non-modular older PSU in which case the link I gave would have solved your problem.

                                               

                                              I don't believe this affected your EDC since it was a misconfiguration problem rather than a power problem.

                                                  I'll have to do some digging around, I put all of my spare cables away in a safe box somewhere and now I can't recall where that safe box is (always the way when you need something).

                                                   

                                                  Worst case scenario is I but a molex adapter and use that. I'm struggling to find a replacement modular 4-pin connector online, but if molex-to-4pin is okay then that'll make do.

                                                   

                                                  Thanks again for all the info/help!

                                                      For now just see if your computer is working fine without the 4 pin CPU connector connected. Since it seems to be "Optional" i would just wait and see if you have any issues with your Ryzen CPU that may be related to Power.

                                                       

                                                      It seems for Normal Usage and not heavy Overclocking, your 8 pin CPU Power connector should be fine as hardcoregames™ mentioned in a previous comment.

                                                noxenvon, this is a serious problem.  Both the 4-pin and the 8-pin MUST be powered.  I did a search in this thread for power and I guess I found my own power supply.  You should have at least a 750 Watt supply with 4 and 8-pin CPU connectors.  I suspect you need a new PS not just more cables.  I think you need to deal with the power problem and then if EDC is still way high, try cooling options.  I would not suggest you change your current fan setup.  Enjoy, John.

                                            given you are running your gear at stock, you should have little to worry about

                                             

                                            check for BIOS updates and make sure windows is updated and you should be fine

                                             

                                            video drivers are a tad flakey sometimes but often a game patch will fix most problems

                                                Video drivers are set to automatically update and i reinstalled the latest version (Nvidia drivers) earlier today.

                                                 

                                                I say running at base speeds, but the processor seems to fluccuate randomy. THe stock speed is supposed to be 3.7, but it runs anywhere from 3.9-4.135 without any input from myself... I don't know why it does this, or how to correct it, but it's what came out the box so i'm not touching it xD

                                                    noxenvon, I suspect your varying speeds are due to Precision Boost.  This can be disabled in the BIOS/UEFI.  The processor boost as conditions permit.  With EDC pegged, boost will be restricted.  Working to getting the 4-pin power cable installed?  Enjoy, John.

                                                      Modern processors (CPU and GPU) both have dynamic clocks to reduce overall power consumption.

                                                       

                                                      AMD GPUs can also switch off parts to reduce even more power when not being used for gaming etc.

                                                       

                                                       

                                                      NVIDIA is doing something like that with more recent hardware as well.

                                                  I've since disabled Precision Boost and Core Boost in the BIOS and I'm now running at more comfortable temps (65-70% EDC) at base clock speed of 3.7GHz. While that may be selling the 2700x short of what it's capable of, it was never my intention to overclock on day one. I got the parts with the options to OC in the future, and I've learned a lot more from this experience than I thought!

                                                   

                                                  So once again, thanks to everyone who posted/left feedback/gave support. I'm wiser for it now!

                                                    I have the same issue: EDC is always around 100%. Reducing power plan state help me down EDC to 30-40% in idle but if I run any software it jump to 100%.

                                                    My MoBo ASUS Prime X470-Pro, CPU 2700X, PSU 650W. All power cables connected (8x, 4x). 2 fans installed in my case for in and 2 for out air. I'm curious how AMD Ryzen Master software calculate EDC? Is it posible wrong EDC calculation?

                                                      Me too just with an MSI X470 GAMING PRO, 650 Watt EVGA SuperNOVA 650GQ PSU and a 2700X. Also both power cables (8x,4x) connected but Ryzen Master tells me "99% of 140A, Limit 168A"

                                                      Sounds like the PSU isn't strong enough??

                                                        Actually the whole Ryzen 2700x system takes 300-400 W (including video-card and etc.). I don't think that a PSU with 650 W is not enough for Ryzen 2700x. My opinion the software works not correctly.  If you calculate the power consumption of Ryzen 2700x you will see that 140 A is too much for it. By default Ryzen 2700x has 105 W TDP and average voltage is 1.35 V. If we divide 105  by 1.35 we get 77.77 A. This is average amperage for Ryzen 2700x. But Ryzen Master shows us 140 A. This is nonsense!

                                                            By that logic, it sounds like a bug in the Ryzen Master software. On the record, the very last reading (last box on the left, i cant recall the name as i’m on my phone right now) always reads at 95%. I think its the temperature reading for something? I will update when i’m back online proper but I think overall the Ryzen Master software needs some more tweaks to it if its giving more than just one person these false readings. I can’t see how at base clocks my power draw is still clocking in at 75% :/

                                                            For more or less correct information about your Ryzen you can get from HWiNFO64 v.5.86-3480 (don't mix with another software with similar name).

                                                            I don't trust the Ryzen Master software. It's too "green" for now.

                                                                I’m back on my PC now, Ryzen Master has been updated properly and my readings show 70-75% of 140A on EDC and 95c on the PTC (which has been a known bug for a while, apparently). I’ve added a screengrab below of what my current readings are, this is with Precision Override and Core Boost settings DISABLED in BIOS and I’m also using Master default settings. Absolutely nothing has been changed.

Surely, for light gaming and browsing sessions my power draw shouldn’t be that high.

                                                                  1. All motherboards for Ryzen use aggressive voltage (over 1.35 V)  when a CPU in burst mode. Which is not good for a CPU (high temp and degradation chip).

                                                                  2. To save your CPU for long life you need to find balance between voltage (temp) and frequency manually setting in your BIOS.

                                                                  For me CPU voltage is around 1.24 V and frequency is 4 GHz. With these parameters I don't have high temp (loading all cores - temp 65C with Noctua D-15, idle - 40C).

                                                                  Read this topic and you will see how voltage depends on temp and etc.

                                                                    BUT!!!

                                                                    Personally I changed the processor power management. In the Balanced power plan options the minmal power condition is set to 5%. The Ryzen CPU power plan is set to 90% on default. It seems to do the trick. I changed the minimum power condition to 40% with reduced EDC to 25-40%.

                                                                    I tested it afterwards with some multithreaded tasks and the CPU boosts up to 3,9GHz on full load.

                                                                    Afterwards I set the same 5% as set in balanced power plan and now my PC is idling around 1550 GHz an EDC 25% at 0,79V

                                                                            If you seem to find the right settings, feel free to share. Right now for me 40% does the job!

                                                                                Gigabyte X470 AORUS GAMING 5 WiFi, AMD X470

                                                                                So, I think a system with this configuration should fly. Yesterday I was using one virtual machine (vmWare) and I barely could move the mouse, neither on the virtual system or physical system, even though cpu utilization on windows was showing 2 % only. Im not a gamer, so i`m not intending to overclock or anything, I just need a System that doesnt freeze.

                                                                            Hello guys,

                                                                            I recently build a pc with Ryzen 2700x + MSI x470 gaming m7 and I'm concerned about Ryzen Master showing EDC at top on gaming

                                                                            Core Boost and Precision Boost Overdrive are set to ON.

                                                                             

                                                                            At HWMonitor app all the temps looks fine, but TMPIN7 (don't know what this sensor represents) sometimes get hot (90c sometimes)

                                                                             

                                                                            Any solution ? Or I do not need to worry about it ?

                                                                            On internet I've already looked in so many divergent opinions.
