1usmus Power Plan for AMD Ryzen - New Developments

[willgart]

because you think that the entire world is playing with the bios?
overclock and try to push the PC to the limit???
who installed ryzen master? and hwinfo etc???
so yes, AMD and MS can provides tools or API to allows some fans to play with the system.
I dont care about the mass and the default config.
I care about what I can do myself, and I dislike to be locked.

76.4ns is terrible memory latency, that's not running 1:1 with the IF. Even at 3600MHz you should be close to 70ns, if not below with that RAM.
If I were you, I'd go check your UEFI settings.
I'm also pretty certain that the RAM can run at 3800MHz without breaking a sweat, but that takes some more tinkering.

i did get 74.5 with the fast settings from the memory calculator with it was custom settings not XMP. how should i check the settings?

i will check again the settings, maybe I did use the wrong sheet

You probably have the memory speed set correctly but you also have to set Infinity Fabric speed the same as exactly half of memory speed. If you have memory 3800 you have to set Infinity Fabric speed to 1900.
In most bioses you can do that in AMD CBS menu.
There is a small problem that most ZEN2 CPUs can't handle IF speed that high, 2 of mine tops at 3733 (1866) MHz so you may have to lower memory speed to match and tighten timings to compensate. In most cases it is a better choice for gaming performance as well unless your memory is able to run above 4000.

ok will try and see...

well i did put 1900 clk but not make any big change...still 74.1ns - 73,9, 74.0ns did 3 runs speed is the same in aida64 as on the memory10 -13 pics

Try 1866mhz
its the maximum supported speed, higher and there is a drop in memory access.

[X570-3900X-DE]

here my settings for the memory

yes 1866 is 64.1ns... speed is about the same read a little more, did put the fast setting like this...

so did a few test so you can see and yes you are right... its faster over all in CPU-Z also

so thanks a lot for telling me and your help !!!

Cinebench20 was 7337 with 1900mhz now max 7381 with 1867mhz as PBO off no OC

There are three settings that matter and I don't think you've found the third.
System Memory Multiplier and FCLK Frequency you seem to have worked out, but you need change the Infinity Fabric Frequency and Dividers setting under DDR and Infinity Fabric Frequency/Timings in the AMD Overclocking menu as well (which is under XFR Enhancements and then you need to select Accept).
It seems like you might've found it already though, but only for 1866MHz, so try increasing it a bit more and you might get a smidgen more performance.
You can take screenshots in the UEFI by plugging in a FAT32 formatted USB drive and pressing F12, just as a future reference.

Nope, 1900MHz works just fine, but you have to manually set it.

 

[X570-3900X-DE]

so not sure what is better.... it showed its close just the ns were 74 in 1900 vs 64 in 1866, you can see my tests what i had with 1900 a few post up

yes F12 in Bios works thanks, did not know that.

I will do more tests this evening here... just maybe you could post some sheets of your speeds so we can compare it

you can found a lot of youtube video on the subject of the ram speed.
check the Linus tech tips one.
in most case, having a lower frequency but also a lower CAS is better
if you have a CAS of 19 at 1900mhz, but 18 at 1800mhz, you can have a better performance at 1800 than 1900.

New AMD Chipset drivers are now out ! (v.1.11.22.0454) [25.11.19]

1usmus can you confirm whether AMD has taken into account your findings on their power plan ?

Edit : New AMD Ryzen Master is also out

 

[X570-3900X-DE]

cool so more test after

with initial test,I found that its better now. (more test to do with default bios config for example, not tweaked one)
apparently now the cores are sleeping quickly then before. which reduces the temperature at IDLE for me.
I'm still below the target values I expect from my 3700X, with PBO maxed, I cant reached 4200 during R20 single core tests (but apparently, I'm able to go up to 4350 with Windows background activity)

and for info hwinfo64 has been updated too. and the preferred cores has changed.

 

[X570-3900X-DE]

i did a quick boot and only see 4300mhz... so i changed to universal and right a way 4550...... did a new test as i could not get 1900 to run... so only 1867 is stable...

so still happy with what i see with PBO off and no OC on the CPU.

 

[Weshya]

I personally noticed worst performance (or so i think) somewhat by using the newest chipset + AMD balanced power plan (CPPC + CPPC Preferred Cores enabled)
Not even 1 core is boosting at 4.2 (Ryzen 3600) after 5 minutes of having boot in Windows, without opening any application (apart from the automatic start up ones and HWiNFO obviously)

When i apply 1usmus universal power plan (CPPC + CPPC preferred cores enabled), i immediately see more core boosting at 4.2 + better use of fastest cores after only some minutes after booting into Windows

Another strange fact i noticed, is that when i disable in BIOS CPPC preferred cores but i keep CPPC enabled + use the AMD balanced power plan, i have the same boosting behavior as when i have CPPC + CPPC preferred cored enabled + 1usmus universal (More cores boosting at 4.2 + better use of correct fastest cores) .

At the end, i may be wrong but i tried three times this procedure and i was able to reproduce it every time.

Once again , i have no clue as to which setting i should stick to in order to get the most out of my Ryzen 3600...

i also felt that using 1usmus Universal Power Plan was the better way to go... did you check the setting in the power plan

this here

On a side note (but still relevant) i noticed that on my Desktop PC, under Power & Sleep>Performance and energy, there's a slider that can be used to control the power plan in use (?). Since i really don't know if by choosing another preset (other than the default "better performance") it would replace my current power plan (1usmus Universal) , i decided to make a quick test.
I noticed that if i choose "Best performance", it behaves as if I've chosen the "High Performance" power plan, BUT retaining the 1usmus universal power plan benefits.

So i am kind of puzzled as to what this setting has to do on a desktop PC. Is it to fine tune the already chosen power plan under control panel ?
I suspect that the "better performance=balanced" option should be chosen if our current power plan is 1usmus, or not ?

i did go on best performance

i did go on best performance

Ok after further testing, when i set the "Power Mode" to "Best Performance" + 1usmus universal power plan i have more core boosting at the max 4.2 and faster + unused cores are in sleep mode as it should (checked with Ryzen Master). I also noticed a tad higher Vcore voltage when idle , compared to "Better Performance".

So this slider definitely does something to fine tune the existing power plan , transforming 1usmus power plan into a "High performance 1usmus universal plan" one could say ?

P.S : When i choose AMD Balanced power plan + Power Mode on "Best Performance", i notice more cores are boosting as well to the max 4.2 but less cores are in sleep mode compared to when it's on "Better performance"

So i guess i am also going to keep the "Best Performance"

 

[X570-3900X-DE]

did you check if your BIOS has PBO setting i had to turn mine off to get higher boost, did not like the auto setting

I have PBO on disabled on BIOS

 

[X570-3900X-DE]

good me too, i also keep the Best performance very happy with the total results, so not sure what else you could check. The rest that was needed is set in the bios and its the latest?

maybe the other guys can help as maybe one has the same CPU then

I am just sharing my thoughts/findings here after the new AMD chipset drivers and trying to figure out what are the best settings finally to have : ) Thank you nevertheless

 

[X570-3900X-DE]

that the list i made, maybe there is something you can try

to find the best setting was also my goal here, i got a few good ideas here and help.

1usmus can you confirm whether AMD has taken into account your findings on their power plan ?

Edit : New AMD Ryzen Master is also out

Ryzen Master did not change the algorithm for determining core ranks.
Also, I do not see any changes in the power profiles. "Duty cycle" is also disabled by default for Ryzen Balanced. That is, the problem was presented to the public not as a bug but as a features.
Perhaps they did not have time.

 

[X570-3900X-DE]

please keep up the good work, thanks again

 

[willgart]

for me, the new drivers had finally an impact.
after few hours of activity on my PC, I can see (using hwinfo) that my 2 fastest cores hit the 4.4ghz, the 2 next 4.35 followed by 4.32 and 4.3ghz (its a ryzen 3700x)
this is following the AMD core ranking for my cores.
in single core tests, Windows still use the 2 best cores (the best average I mean)
so there is some improvement for me.

 

[1usmus]

Still not quite there yet.. PBO is disabled, all other background processes disabled. Missing anything?? Temps are in the low-mid 50s during C15/C20.

Have you tried the new chipset drivers?
I also want to advise you to remove RM or drivers using Revo Uninstaller Pro. This program allows you to find all traces in the registry and files. Very useful for Ryzen users.

this is great news
