PC Processors

[actionoid]

Having re-read a bunch of foreign and not so much forums, having reviewed a bunch of videos, I came to the conclusion that I lost in the "silicon lottery". Or did not ?

Just yesterday I found a video with the same build as mine: R5 3600 + B450 Mortar Max. There i'm could clearly see that in the game the CPU frequency was constantly in the range of 4.175/4.200 Ghz, at 60+ degrees. In my own case, in the same game and, in principle, in any other game, the frequency is at 4.05/4.075, at an average temperature of 55 degrees, that is, above 60c temperature does not rise in any game. When i'm turn on PBO with 10x scalar and AutoOC +200 Mhz, only 50/75 Mhz is added, and the temperature remains at 55/58s, but the average voltage in games grows by ~100 mv and so it was decided to turn off PBO due to its complete useless. In other words, even with PBO there are no frequencies specified by the manufacturer.

Below is a screenshot from Far Cry 5, which, according to the idea, lies more on one core. Does anybody have same problem ?

PS: Bios is the last one, nothing has changed on previous versions. Windows 10 with the latest updates. Tried different power plans.

Hello actionoid,

what is your Power Saving mode please ?

did you tried Ryzen high performance ?

[actionoid]

Hello, mccharle. 

Currently using high performance with 100% minimum and maximum cpu states. Im tried all windows plans, amd and custom plans like '1usmus ryzen plan' and '1usmus ryzen universal' - nothing changed.

Here is another screenshots for more information (idle, while gaming and last two from the video i'm talking about).

Volts and temps under CB20

I'm also tried a negative offset (-0.0500 / -0.0750) - its reduced temps and voltage under load and added 25\50mhz while run CB20 (1.325 stock / 1.300 with -0.0500 / 1.276 with -0.0750 ). In games with offsets i'm notice only missing additional 25\50mhz

Think that i'm finded a way to see max boost frequency and FlatOut helped me with that. But what is going on in other cases ? Temperature ? Load factor ?

[mccharle]

Hello actionoid,

I think we are forgotten something about max freq. Max boost freq is not done on all cores and it is depending on power/thermal cpu package.

Also I found on the web few forums how are talking about R5 3600 that doesn't reach this max freq without a recent bios.

Can you check the bios version and try without any over clocking. Sometimes overclocking cores may result in boost reduction.

[actionoid]

It was completely stock, without any manual oc or pbo, only default core boost. All this screenshots show stock cases

[actionoid]

As i say before, i have latest bios. All options in bios is auto, only xmp enabled

[mccharle]

I just installer Ryzen Master and done some tests, bad news with stress software installed I can't reach max speed to(4700MHz).

I do not know what to think of AMD, even on a single core I am far from the 4700MHz announced like you.
My conclusion, the boost is very variable from one CPU to another. As the majority of applications are multithreaded I don't mind but the question arises about the figures put forward by AMD.

If someone else have an idea ?

[actionoid]

Looks like the boost frequencies in some cases are so overpromised.
