R7 2700X EDC

[FallenEngineer]

hi there,

my ryzen 7 2700x with gigabyte ax370 gaming 5 work with 3 different powers type:

in windows high performance, all of my cores clocked at 4.0 GHz and resulting in 99-100% EDC

in windows balanced performance, all of my cores fluctuates from 2.2 - 4.3 GHz, and resulting in fluctuating EDC from 40-100%

in windows power saver modem all of my cores clocked at 2.2 GHZ, and resulting in stable 30% EDC

 

EDC stated as Peak Current Limit CPU, however if i choose high performance setting, it always sit at 99-100%. is it dangerous? and any of you know how to reduce it while i still have my cores all clocked at 4.0 GHz?

Nah.

 

But if it worries you that much,

go to power settings > changed advanced power settings > processor power management > minimum processor state

Set it to 5%

You won't get the max out of your CPU if you use Minimum Processor State above 45% I think.  Anything below that will let the CPU go through all of its states.  So you can use any power plan as long as you change the Minimum Processor State to something below 45%.  The EDC staying at near max I don't think hurts anything other than being an indication you're not getting the maximum performance out of your CPU.

do you know what EDC really is? please explain it to me

nah, it changed from maxed 4.0 on all eight cores to 4.2-4.3 at some core and 2.0-2.2 at other core. but EDC still fluctuating around 90-100%

• Package Power Tracking (“PPT”): The PPT% indicates the distance to maximum power that can be delivered to the socket by the motherboard across various voltage rails. 100% indicates maximum capacity.
• Thermal Design Current (“TDC”): The TDC% indicates the distance to maximum current that can be delivered by the motherboard voltage regulators when they have been heated to a steady state through sustained operation. 100% indicates maximum capacity.
• Electrical Design Current (“EDC”): The EDC% indicates distance to maximum current that can be delivered by the motherboard voltage regulators in a peak/transient condition. 100% indicates maximum capacity.
• Fastest Core Detection: The stars represent the fastest core(s) within each CCX, while the gold star indicates the fastest silicon in the entire device. The circles represent the second fastest cores within the CCXes. This can be extremely useful for breaking single-core clock speed records.
• Per CCX Overclocking

will it hurt the motherboard if it stays 100% all the time?

Well it downclocking is the designed behavior.  It being able to downclock allows it to boost single core performance.  However, I am surprised EDC is staying high.  Mine drops down to about 29% of 145 at idle.

I don't know for certain, but I doubt it.  An indicator it is would probably be high VRM temps so keep an eye out.

@FallenEngineer  It does shoot up with any CPU load -- heavy or light.

my processor minimum and maximum state is 100% and 100%. if i changed the minimum to 5%, it doesn't change the EDC, it just allow faster boost clock of some core and reduce the other. however, if i reduce the maximum to 90%, all of my core clock only getting maxed at 3.2 GHz and that's keep my EDC below 55%

If your min state is greater than 45% then your CPU won't be able to enter lower states to allow for it to reach its highest clocks on 1 to 2 cores.  You should see a lower EDC percentages during idle if you have the min processor state set accordingly.
