Hello guys, I want to start by saying that I'm Italian so sorry if my English is bad :D
Moving on, this is my configuration:
Mobo: X570 Aorus Elite
CPU: Ryzen 5800x
Cooler: Noctua NH-D15
Case: Cooler Master H500P Mesh (meh) with an additional Noctua 140mm fan on the top as Intake

I've looked into undervolting in order to get lower temps, I was going on 90C running a MC Cinebench R23, I know that 5800x is a hot boi but those temps were too high for me. (If you want to know the score, I don't have it, I've never ended a run due to reaching 90C)

So I've undervolted with PBO in the bios, setting all cores negative curve with a value of 25 in the Curve Optimizer Magnitude field;
Now I'm on 84C running a MC Cinebench R23, with a score of 15798 and clocks between 4849-4851 Mhz;
On a single-core run I've scored 1603 Pts at 49-51C;

Now I'm curious about 2 things:

1. I've heard that in MSI Bios every unit in the Curve Optimizer Magnitude field equals to 3 to 5 Millivolts, is It the same in the Aorus Bios?

2. Someone had the same issues/went through the same procedure? What values Have you put? Did you set the curve for all cores or have you set different values per core(s) ?

Thank you in advance guys <3

Olá, esses são os valores mais estáveis do curve optimizer que consigo com +125 de boost.

Baseado nos benchmarks dos outros e no ranking do cinebench, minhas pontuações não são tão boas, tem mais alguma coisa que eu possa mudar?

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 !

So. im trying to tune my 5800x again...

Seems like i got a potato. Boosts to ~4.8Sc and ~4.6Ac...I can input up to 2ghz on the PBO2 Boost override but after 200mhz nothing changes. Global max is still 5050, some cores touch that but the effective clocks doesn't so i guess it's just streching.The Cpu gets hot (90c) unless i drop the Vcore to about -0.025v, i get higher/same R23 scores for every step down until then (~15000-15500). I know they are supposed to work at that temp, but that seems stupid if i get the same performance for way less wattage and temp. Electricity is expensive nowdays...

Cpu seems to handle ~-30 Co on all cores, maby -28-29 on the two best, but if i drop the Vcore they give me errors way before that.

PPT/TDC/EDC Doesn't seem to matter when i'm optimizing sc, currently running corecycler and try to find the max Co offset on my vcore, i suppose i shoudl lover Vcore until all of them are between -20 and -30, since they max out on stock, meaning they could go to -40-50 if that was an option.

Is this the right way to go? I'we read 10ths of guides but it doesnt click. And Sometimes my changes work and sometimes it just glitches out, having the same options on 2 places int eh UEFI doesn't help either, dunno if i should use the settings under AI Tweaker on Advanced/Amd, Thanks Asus.

Current values on PBO is 120/75/110, but that only comes in to play when i run all core or R23, i'd like to find the core maximums before i start tuning all core.

Also, if i use LLC on Lvl2 or more i just loose performance? Perhaps 100-150 Mhz All core clocks.I have it set to Auto, and CPU and SOC Current are on 110%, i don't think thats a problem when i have PBO limits way under stock.

Specs:

• Amd 5800x

• Asus Strix 550-F

• 32gb Corsair LP 3200/Cl16

• Gtx 1080

• Corsair VS650 (Shit PSU, a bit low voltages)

My Spreadsheet (WIP)

so i ran auto oc and curve optimizer mode per core , it did its thing and finished succesfully cpu clock speed maximum changed from 4,8 to 4,95 in cinebench it still doesnt go above 4.6 tempretures never reaxh 80 degrees https://imgur.com/a/rBqDa2x

Ciao a tutti! È il mio primo post, quindi siate clementi, per favore.

Mio padre ha recentemente aggiornato il suo PC e mi ha regalato il suo vecchio 5800X e due banchi di RAM, il che è stato un bel miglioramento rispetto al mio 3700X. Adoro armeggiare e ho iniziato a giocare con il curve optimizer per core per massimizzare le prestazioni mantenendo le temperature al minimo. Questo 5800X in particolare sembra essere un vincente nella lotteria del silicio e la mia "taratura" attuale è la seguente:

• C1: -27, C2: -27, C3: -28, C4: -18, C5: -22, C6: -27, C7: -27, C8: -17 come raccomandato da Ryzen Master ma impostato manualmente nel BIOS

• Scheda madre: MSI MPG X570 GAMING PRO CARBON WIFI con l'ultimo BIOS

• Limite PPT: 150W, Limite TDC: 95 A, Limite EDC: Auto, Precision Boost Overdrive Scalar: 10X, Override CPU Boost Clock: Abilitato, Max CPU Boost Clock Override (+): Auto

• RAM: 2x Corsair Vengeance LPX 3200Mhz CL16 e 2x Crucial Ballistix 3600Mhz CL16, ho ricevuto le Crucial da mio padre ed entrambi i kit ora girano a 3200Mhz 16-18-18-36

• Clock dei core riportati a 4.850Mhz in HWiNFO, tutti i successivi riferimenti a clock e frequenze si riferiscono al clock effettivo

In carichi di gioco più leggeri come Rocket League, i clock raggiungono un massimo tra 4.880-4.983Mhz, mentre Cinebench R20 e R23 vedono clock multicore intorno a 4.675-4.750Mhz con single core intorno a 4.850Mhz. In CPU-Z il multicore è a circa 4.825Mhz e il single a 4.850Mhz. Ricordo anche di aver visto clock superiori a 5Ghz in Minecraft.

Questa taratura è stabile in R20, R23, Prime95 e CPU-Z, ma a volte causa crash per carichi più leggeri come Rocket League (a volte solo il programma, altre volte l'intero sistema). Questo problema è stato risolto aumentando la tensione di "2" per tutti i core nel BIOS, il che mantiene le frequenze agli stessi valori per carichi pesanti, ma le diminuisce leggermente per carichi più leggeri (max Mhz circa 100 in meno).

TL;DR/Domanda: Qualcuno sa se è preferibile aumentare le tensioni o cambiare il Max CPU Boost Clock Override? Le mie temperature sono sotto controllo (anche se sto usando un H100i da 240mm di quasi 15 anni) ma mi piacerebbe sentire una discussione e le vostre esperienze!

Recently experimenting with undervolting my 5800X3D. Temps are roughly 10C cooler and it clocks slightly higher all while drawing less power. I am using PBO2 Tuner at the moment, but I would love to actually set voltage offsets from my BIOS. From my understanding somehow it's locked/unavailable for the 5800X3D, but some people got it working by loading a BIOS profile for their old CPU (see this thread). Does anybody know if there's a workaround? I am running ASRock SteelLegend B450 Motherboard (P4.30). Does anybody have a fitting CPU profile I coud load to "unlock" PBO settings? Or maybe there's a new firmware version that fixed this?

Hi, everyone

Over the past few days I've been working on lowering the temps of my Ryzen 7 5800X using curve optimization. After a lot of work I think I'm finally getting close to a stable curve.

Over the next few days, I'd like to adjust PBO to further bring down temperature of my CPU. My question however is the following:

Will changing PPT, TDC and EDC affect the stability of my Curve Optimization?

Thanks in advance!
