Thanks mate. Is that for pbo in ryzen master? Or precision boost in bios?

You can set the PPT TDC and EDC settings under pbo in Ryzen Master or precision boost in the bios - they're both the same thing, however you need to go in to the bios to change the curve. I set my initial settings in the bios and then I can tweak the power settings (PPT, etc) in Ryzen Master afterwards if needed.

I do it in the BIOS
Cheers guys, I invested some time learning PCO2 and the curve tonight. I am currently stable at +150mhz boost and -5 negative on all cores. When I tried +200mhz and -10 on all cores it kept crashing. I think my 5800x needs quite a lot of voltage to hit 5ghz and my cooling, while decent, is maybe not quite strong enough to handle the heavier PBO action.
I will consider an Arctic Freezer II 280mm...

It’s a great cpu I got mine for £380, and I am cooling it with the 360 kraken from my former 3960x cpu, stays below 80deg cel under load. My cinebench score match my old 1950x. Half cores same performance. I like it a lot. Used for gaming and look dev for 3D graphics. I wish I could have kept the 3960x but needed funds. In terms of clocks, I am only using ryzen masters precision boost and getting 4.79 on all cores, they do go over that sometimes, but only random cores 2 or 3 at a time upto 4.85ghz. Not really kept upto date with manual overclockingbut would love to have time to research, but have a masters hand in due, so no spare time. Board is Msi x570 tomahawk. The ram is 128gb 3200 hyper x fury, which I cannot get over 2666mhz at the moment.

WTF dude, 128GB? No wonder you can't get over 2666mhz.
I think I will get myself a sealed watercooling loop, seems to make sense from a performance and noise perspective and they are retty cheap all things considered.
I seem to finding a standard over ride on the voltage and change all core to a set voltage (4.625ghz) for me right now, I can stress test for a couple of hours at 1.265v with my 5800x.
I've found I can do 4.7ghz+ but it takes 1.33-1.35v to be anywhere near stable.
Not tried curve optimizer/pbo yet but will use recently posted youtube video to take a look into the finer details and see if I can safely maintain more.
To me, 4.625ghz @1.265v is fairly safe and will run at a max temp of 70 degrees C after a couple hours of heavy stress testing.

Hi, Have you got a link to the video mentioned pls.
Now that I have got to grips with PBO I ave my doubts on the suitability of my air cooling to maintain a consistently high PBO rate under load. I need to see if I can fit one in my case.
Try these:

I noticed that on latest BIOS PBO boost on my 5800X wont go past 5025mhz even if you max it out.
BIOS 5809 (AGESA 1.1.8.0) I was able to run my 5800X up to (225mhz) 5075mhz rock stable. I could run it as high as I wanted but past (275mhz) 5125mhz it would crash.
BIOS 5822/5837(AGESA 1.2.0.0) both have PBO boost locked at 5025mhz. Even if I put in 200mhz boost which should be 5050mhz(2850mhz +200mhz) it wont go past 5025mhz. Even going to 250mhz boost nothing, still 5025mhz.
Was wondering if anyone else has seen this with there 5800X or any other 5000 series CPUs?

I have a different mobo but I was getting crashes at +200mhz and negative offset and even when I did figure out max benching settings the difference was negligible.
I just now tried to set PBO mode to Eco 95w and my multi-core score dropped around 6% to 14680 but my single core went up to 1600. Temps are way lower too.
Aparently AMD are restricting the max boost override to +200mhz now but you still should get 5050 unless it's a bug, is it still boosting to 4850 at stock?

Only just updated to 5837.
Didn't try the +200MHz on the earlier versions, but my max boost is also 5025MHz.

Thanks a lot.

Hi, Can some of you that have the 5800x under an air cooler give me an idea on what temps to expect please. Idle, browsing, benchmarking & Gaming would be appreciated, I've just got mine and currently I'm using a be quiet Dark Rock Pro 3 cooler, Idle I'me getting high 30's, Browsing I see spikes into the 50's and gaming gives 70's with benching going into the 80's, these are all with the stock cpu settings.
Those are perfectly normal, indeed good, temps for Ryzen 5000 air cooling.
Soldato
Yeah those are fairly good. I started with the Wraith Prism air cooler and you could add 5-10 degrees to each of your temps for what I was seeing at stock.

I have a 5800X, completely normal temps those.;
My idle temps are high 20s to low 30s, but are about the same as yours for every thing else. (also stock settings)
Cooled by a Brocken 3 and am really impressed.

That good news, It'll be interesting to see how I do overclocking on air, Thanks a lot peeps.
