Hi everyone,
New owner of 5800X rig here. I made my fair share of investment to make my machine as quiet as possible and noticed that Noctua NH-D15 is good enough to warrant fair headroom for OC before taking off. I was fully aware that 5800X is quite hot out of the box, so I started tweaking nearly instantly with how to tame it - I managed to figure out the following using scattered info on this sub:
-
Curve optimizer per core, all cores at -30 (automatically set by Ryzen Master)
-
PPT/TDC/EDC: 120/80/120
-
Boost override CPU: 200
-
Temperature limit: 85*C (I set my fans curve to be as quiet as possible before 80*C mark, after they linearly scale with temp to 100% at 90*C)
-
FLCK & others - auto
I have not touched any other values to simply prevent myself from doing any damage to my mobo/cpu. Current Cinebench R23 score is 15294 compared to original 14100-ish, machine sustained Prime95 + Furmark for half an hour without being noisy nor any odd behaviors.
My CPU-related specifications:
-
Ryzen 5800X + Noctua NH-D15
-
Gigabyte AORUS ELITE v2 B550 (latest bios)
-
32GB 3600MHz CL16 Kingston Renegade Black
-
Seasonic PX-750 Platinum
Are there any other things I can try optimizing? Are any of those settings unnecessarily high/low? I do not mind "safe" overclocking, as long as it doesn't mean double digit wattage increases for tiny gains. Thanks!

I recently upgraded to a ryzen 7 5800x and very new to PBO2. I was watching a bunch of videos online and tried to come up with my own custom settings for a stable setup. Here are my settings so far:
PBO Limits: Motherboard
Curve optimizer: Per Core Negative 15 on all except for Core 3 and 7 which are the star cores from Ryzen Master
I also set the Platform Thermal Throttle Limit to Manual and set it to 70C. Is it bad that I am forcing such a demanding limit? If i keep it to auto my cpu still occasionally skyrockets to the 80's level but on average manages to keep a mid 60s level in games. With the above settings im doing a multicore score on r23 of 14337. Im not too particular about synthetic benchmark scores I just want to be working on a stable temps within a 70-71C max because I've also found the sweet spot undervolt for my 3080 ti to run at the same temps
Hi
2 days ago i started with tinkering around in my pbo 2.0 settings for better temps i think i need some help with it my effective core clock doesn't match with my normal clock is that normal? its a differences around 250 MHz in MC Tests what makes me very unhappy right now. My Clocks are on the picture with HWinfo is there any way for improvement and keeping the same temps
My Setup:Ryzen 7 5800x
Asus Tuf RTX 3080 Ti
DDR 4 3600 Crucial Ballistix
X570 I AORUS PRO WIFI
all in a mini itx Nzxt H1 v1 at Max 78-79 Celsius idle around 43
My Pbo Setting PPT: 130 TDC: 80 EDC: 120
Scalar 4x (what does actually nothing for me)
CPU Boost Clock overdrive: 50 Positive
Stable Tested with OCCT Core Cycling Curve Optimizer: Core 0: -27 Core 1: -30 Core 2: -30 Core 3: -21 Core 4: -20 Core 5: -20 Core 6: -20 Core 7: -20
Score R20: MC 5725- 5750 Pretty Bad i Guess at stock its higher SC 625
CPU-Z: MC 6555 SC 672
Score R23: MC 14663 SC 1590
Already Thx for every reply i will get from you guys <3
Why are you running TDC and EDC at 100%? Use PPT to control temps, raise TDC and EDC a bit higher so they are not hitting 100%, only close to it. Score is low because your TDC and EDC are too low.
Why are you worried about temps at all? Let PBO run what it wants, it's safe.
Why are you using scalar in a scenario where you are temp limited? Set that to 1x or auto.
CPU boost override should be set to where you are reaching the highest scores, 50 is probably too low. If it's unstable when being raised higher, you're losing a lot of low-threaded performance due to aggressive CO undervolting. I'd rather tune CO at +200 override and maximize low threaded performance. If you need good multicore for a specific workload, better off setting a manual all core OC.
Clock stretching could be because of too aggressive undervolt, could also be because of hitting EDC limits.
I had better cb results but much worst sc in cpu z :_; with higher settings
In general, I set all the cores to 30. Curve +200 MHz and the processor seems stable. Passes OCCT tests. In CB23 14400 points, all cores keep the frequency of 4600 MHz and the temperature of 75 - 77 degrees. It seems that the curve cannot be with such an offset for all cores. I ask for help and, if possible, detailed explanations about the settings. Thanks a lot.
Doubt your chip can do -30 all core +200mhz. How long did you run OCCT for? 1hr? What settings did you test surf OCCT?
-30 to all cores may run under load, but you will likely experience issues under low load (meaning idle). You may experience crashes when idling then attempting to return to normal load, or while doing light load tasks (web browsing). Would recommend testing with everyday use, see it it crashes, if it does, go to 25, then 20, until you find something stable.
Best practice is to use “per core” to get the most out of your cpu, since the “best” cores will be utilized more frequently, they typically cannot have as much of a negative curve as the rest of the cores. Hope this helps
Good day y'all ! I am done overclocking my RAM, so I also decided to go and ask you guys for the best PBO curve optimizer undervolt for my processor.
Thank you guys and have a good one !

Hello, I made pbo on Ryzen 7 5800x processor. My settings were ppt 120, tdc 75, edc 130 and curve optimizer was all cores negative 25.
After made these settings, I tested with cinebench and the test ended and the computer did not shut down. When I start playing games, for example CS2, after playing about 3 games, the PC shuts down or after spending 3-4 hours on the computer. I Tested the temperature and The temperature never exceeded 70 degrees. My main reason to do pbo is decrease temperature. So, I'm not really interested in overclocking, but my goal is to reduce the performance as little as possible and reduce the temperature.
What should I do? I appreciate if you help me :)
Hey all, just wanted to share my experience with PBO/CO settings after tirelessly sifting through too many confusing reddit and forum posts about "optimal" curve optimizers and PBO settings. I was having issues with Ryzen auto-tuning CO/PBO settings, it never said it was stable. And yes, silicone lottery, what's your cooling situation, yadayadayada... Got it to find a per-core setting that was stable, with much lower PBO settings than the motherboard "out-the-box" settings (Running Gigabyte x570 Elite Wifi. It found -25 to -28 undervolt per core as opposed to my -20 all core settings. Cinebench wouldn't finish, PC just kept stalling/hanging and rebooting, and anytime I did get a benchmark to complete, clock speeds topped out at 4.85 GHz 75 C loads (Ryzen master settings) compared to 5.1 GHz 69 C loads (Mobo/Advanced UEFI PBO settings, -20 All core).
TLDR; out of the box mobo PBO settings and finding a stable all core undervolt gave me faster and more stable overclocks than struggling with Ryzen Master and 'optimizing' based off forum & reddit posts. Everyone's PC will be different, but if you're wasting time and struggling to find decent performance from RM PBO/CO settings, I suggest just using your motherboards limits and finding a stable all core undervolt in UEFI. Much easier and less frustrating.

Salut tout le monde !
Je suis nouveau dans l'overclocking et je cherche à obtenir plus de performances de mon 5800x que j'ai depuis 2 ans.
Voici mes spécifications actuelles qui peuvent être utiles dans ce processus :
-
5800x
-
Corsair RM650w 80 plus gold
-
X570S Aorus Pro AX
-
32GB 3200mhz de Corsair Vengeance
-
NZXT Z53 240mm AIO.
Dites-moi comment je peux commencer avec le PBO !
Merci !
After overclocking the ram I wanted to try buffing up the cpu. What i learn is that PBO is the way or a static OC. But i don't understand vdrop.
I decided to go with the PBO settings. After doing some reading. The defaults are for a am4 105w chip PPT 142 > 152 PDC 95 > 98 EDC 110 > 110
LLC to 3
The temperature went up to 82c during r20 the score when from 5380 to 5542
My only question is. Are those settings too aggressive? To run it on a daily.
I also noticed when i had the PDC and EDC between 80 and 90 the core clocks during r20 never got over 3.6 GHz when i put the others ones. The core clocks got to 4.6 Ghz. With a top speed of 4.9 Ghz
I wonder if I did it right.
