5900x PBO + Curve Optimiser vs Static OC

[maka0]

Bit of back ground information

 

When I am browsing the web, reddit/youtube/etc, I set my Windows Power Plan to Power Saver mode, as this lowers all core voltages to under 1v and keeps tempertures 30-35 degrees

 

With my previous Zen 2 Ryzen, I would flick the Power Plan to Balanced and in Ryzen Master enable my OC to gain performance over stock settings, but also keep tempertures and power consumption low when gaming

 

I have found that, without pushing the 5900x I can achieve 1.18v @ 4400Mhz all cores

 

I only play games, no rendering or any other heavy workloads

 

Now that I have a Zen 3 Ryzen, should I do the same as above still or learn to use PBO2 + Curve Optimiser?

Learn to use it..  All cores @ 4400 is a bit lame.

That is a mild OC, I could push it past 4600 @ above 1.2Xv

Ryzen DOES NOT like static overclocks.
You can easily damage the chip.
Running PBO and the Curve Optimized is highly recommended.

If you are only playing games PBO can easily boost single cores much higher than your static overclock as well.

what about keeping idle temps low while running pbo + Curve Optimized? Would it still be viable to use Power Saver mode for browsing the web, reddit/youtube/etc?

Curve Optimizer should bring heat down a little.
Ryzen runs hot regardless, get a good cooler if you're really worried about temp.
As for the power profiles, you shouldn't really be running anything other than the balanced preset for Windows, it will adjust itself.

Expect to see lows of 40c and highs of 80c for a healthy PBO optimized system.

I have a Dark Rock Pro 4, I believe this is sufficient enough

Most likely, yes.

I'll assume seeing the voltage jump around up to 1.45-8 is normal for these CPUs?

That's normal for very light workloads and single core performance
Multicore it should never go above 1.38 max from what I have seen.

Could you explain why Ryzen does not like static OCs please?

because of the process nodes
they're very small
people often overclock these new ryzen processors like their old 3570k's and just crank that voltage to something rediculous like 1.45
however, even for a few minutes of running @ voltages higher than 1.3-1.35 static you can easily damage the core if you are unsure of what you are doing - running above 1.35 with pbo is fine as it does it for less than a micro second and switches very fast.
ryzen does not like static voltages because it pretty much wrecks and burns the transistors on the chip.

If I keep static voltages well below 1.3-135 and only use an OC while gaming it should be fine?
When everything is left on stock settings, while gaming I am seeing all cores above 1.3v... is not in that "damage" range?

[freeagent]

I have pushed 1.45v all core and the heat is insane. If it was a 5600X I would run that all core as high as you can, it is much easier to cool. It’s your chip though, run it the way you want to. A little OT I see a lot of people say Ryzen runs hot.. it doesn’t. Cooling it is very easy.. just gotta put up with a little noise.. which many people cannot.

Not with PBO. With a static, yes.

How does this sound to test PBO and curve optimiser ?

 

Run OCCT, SSE, Small data per core for 5 minutes then change to Auto, Large data 5 minutes per core to help dial in the negative offset it's the curve optimiser

most likely fine
I usually just run 30mins of avx2 for pbo though

Just to confirm in BIOS

Core #0 = Core 1
Core #1 = Core 2

Core #2 = Core 3

...

...

Core #11 = Core 12

 

Ryzen Master says my prefered cores are 2, 3, 9, 10. So in the BIOS this would translate to Core #1 Core #2, Core #10, Core #11?

 

Is the correct?

Most likely, but you shouldn't need that information when it comes to PBO
Also remove Ryzen Master from the system and do all tweaks for PBO in the BIOS
Ryzen Master can mess with some of the settings that you want in BIOS and ultimately screw with something.
Use HWINFO to monitor statistics.

For gaming purpose I found no real gain with PBO + curve optimiser

Onlu improvement I found was in CB 23 compared to default 

 

I don't like high temperature when gaming, like to keep it under 65 degrees

 

If I use Ryzen Master to set an undervolt of 1.25 @ 4500-4600, and only turn this on whole gaming ... Well this be safe and not cause any damage considering people say ""static is bad, keep in mind for other daily use default stock settings will be used and undervolt @ 4500-4600 for gaming only
