i'm sorry :(


NP. I can appreciate attacking this on three different fronts. Sorta kindas. If I had had a problem you'd have been the first to know it Wink Big smile


A response I made in another of your threads:

Important things say 3 times.

Yes, they are.

But I think you're barking up the wrong tree here.

You should read this post by the 7zip Author and then inquire of him why this is happening. When you do, consider CCX and memory latencies.

As you state above, I too am leaning towards this being Ryzen "associated'. But only for the major departure architecturally wise Ryzen represents from prior generations of processors, AMD or Intel.




edit: placed " " surrounding associated. "associated'

Have you downloaded and installed the latest AMD All-in-One driver(s), 17.10 ?

Scroll to the bottom of the info section of the below page to "AMD Chipset, AHCI, USB 3.0 and RAID Drivers"
http://support.amd.com/en-us/download

During installing the 17.10 drivers will install and properly set AMD's Ryzen Balanced Power Plan.


I have latest AMD All-in-One driver(s), 17.10 and properly set AMD's Ryzen Balanced Power Plan...

This is Ryzen Design bug, not my problem
Command Prompt(RUN as Administrator), copy/ paste these lines

powercfg -attributes SUB_PROCESSOR 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE
Processor performance core parking min cores
Value: 25%

powercfg -attributes SUB_PROCESSOR ea062031-0e34-4ff1-9b6d-eb1059334028 -ATTRIB_HIDE
Processor performance core parking max cores
Value: 75%

powercfg -attributes SUB_PROCESSOR f735a673-2066-4f80-a0c5-ddee0cf1bf5d -ATTRIB_HIDE
Processor performance core parking concurrency headroom threshold
Value: 100%

Theoretically, conditions reach of Max Turbo/Max Precision Boost (CPU0~3 active, CPU4~7 force core parking)

OC P-state not perfect solution.
You can also say "You can OC" to Ryzen Pro , B320 mobo or Notebook users? u not

Update: Ryzen 1800X boost with SVM enabled

Ryzen Max Precision Boost is working on a Applications not on your Games ;)
Powered by Google Translate (eng not my native lang)

Ryzen 1700 all core turbo to 3.2Ghz, dual core Turbo to 3.75Ghz max (50MHz XFR)
PS: Maximum frequency = Max Precision Boost (Max Turbo Core Speed)

The "maximum frequency" of Ryzen can be honored?

Winrar or 7-zip with 1 to 2 threads compressed file can really run out (Taskmgr may need to check CPU0 ~ CPU2). Not only can see, but can not use the frequency.

Although the "maximum frequency" is not a lie, but ...

Game is not feasible, may not have a legacy 3D games of can run the maximum frequency, you just casually find some old single-threaded DX9 3D games run, for example ... WoT? (Even without any reviewer "found" this problem?)
PS: Single-threaded 3D games on WDDM = Game thread + display driver user mode communication thread(kernel time usage) = 2 threads CPU useage

The question now
Do not know AMD's SenseMI in hinder CPU4 ~ 15 into CC6, or MS's problem.
Even if the park out CPU4 ~ 15 after playing the game, the frequency still can not work in the Max Precision Boost, suspected to be idle core did not enter the CC6

Of course, the game certainly someone will say what the video card driver forced multi-threaded, the workload(kernel time usage) ran to run the entity CPU more than two cores.
I play video instead of game ("Kernel time usage" compared to the game much less)

The picture is a 4K 10bit test video of the soft decoding, CPU affinity only check CPU0 ~ CPU1, I changed the power plan park off CPU4-CPU15(core parking), you can see the so-called maximum frequency is not used.

Ryzen's "dual-core acceleration" can not on the maximum frequency ah, is the CPU usage problem? But if we will test the program in exchange for 7-zip

Such as 7-zip such as the calculation of the program even if the four threads run over the two cores , acceleration can still reach the maximum frequency (Max Precision Boost)

Is it a good thing to do after SenseMI code analysis? Or is MS not doing for Ryzen?
The maximum frequency of work (7-zip), sometimes do not work (game), use limited where there can be called Precision Boost?
PS: AMD's predecessor bulldozer series did not have this problem

Now can only do ... ... (feel the maximum frequency he returned)

PS: "bcdedit /set {current} numproc 4" be equal to 2C4T = "CPU0~3 active, CPU4~7 force Core C6" (conditions reach of Max Precision Boost)

Is this AMD hope?


Do not talk about the game mode, the game mode will always tile the workload to each CPU, and "Max Precision Boost/Max Turbo" role of the concept of different (only two entities can be active in the CPU, and other idle CPU need to be CC6 out)

V2

No Picture? Please move to my original post[V1]
