Processors

[RPX100]

I have build myself a new PC with AMD cpu and gpu in december.
Have been using Intel and Nvidia for the last 3 PCs before that.

I am looking for some feedback:
- What is the best way to tune my setup for gaming?
- Without disabling the power saving features for desktop use (browsing, movies, work).
- Recommended Windows Power Saving Plan (and settings).
- Recommended MSI 5 click BIOS settings (PBO or manual voltage + clock)

I am asking this here because:
- I noticed that the effective clock of my cpu never reaches max clock.
- Only way to get max clock seems to be cinebench.
- Even on demanding games my cpu clocks are staying below 4 GHz. (cpu usage around 30-40%)
- There are some minor cases of stuttering, because of the low cpu clock, while loading / playing games.

My system specs are:
CPU: AMD Ryzen 7 3800XT (8c, 16t) [cinebench R23 multi: 13328]
GPU: ASRock RX 5700 XT Challenger Pro 8GB OC [driver: 20.11.2]
MB: MSI B500-A Pro (PCIe 4.0)
RAM: 2x 16GB G.Skill Ripjaws V, F4-3600C16 - DD4-3600 MHz CL16
SSD: M.2 Gigabyte Aorus 2TB PCIe 4.0 NVMe [system + games]
SSD: M.2 Kingston KC2500 2TB PCIe 3.0 NVMe [more games]
NT: 650W, 25A 3,3V, 25A 5V, 54A 12V
CPU-cooler: Scythe Mugen 5 Rev.B [max CPU temp in cinebench: 73°C]

Thank you for taking the time to reply.

I just wanted to update this topic with my current BIOS settings.
Maybe someone can give some feedback and let me know if those are indeed best for gaming use.
reminder: I want to keep power saving features enabled for desktop use.

MSI click BIOS 5 settings:
- Global C-State Control -> [enabled]
- Power Supply Idle Control -> [low current idle]
- CPPC -> [enabled]
- CPPC preferred cores -> [enabled]
- SMT -> [enabled]

- XMP -> [enabled]
- DRAM frequency -> [DDR4-3600] (CL16)
- FCLK -> [1800 MHz]
- UCLK -> [1800 MHz]
- DRAM voltage -> [1.35v] (from XMP profile)

- CPU multi -> [43] (4.3 GHz manual OC)
- CPU core voltage -> [1.250 volts] 
- SoC voltage -> [1.100 volts]
- PBO -> [disabled]

I am still looking for feedback why my CPU might not be reaching 4 GHz while gaming.
Cinebench is currently the only thing to get the core boost to max clock (4.3).

I have 4 identical high air flow case fans with custom fan curves maxing out at 70°C/100% RPM.

Looks like this topic got 200+ views so far, but no actual feedback or insights.
I am still looking for advise in any form. 

I have been looking through some YouTube tech reviews and overclocking data sheets...
It is truly amazing how little information they provide regarding the actual used BIOS settings. :rolleyes:

I am still not sure if I should use AMD's PBO + Auto voltage or if my manual OC will work better for games.
These videos that I watched pointed out different use scenarios and different outcomes...
In the end - it looks to me - like there is a 50/50 split between reviewers suggesting either one of those settings.

My cinebench scores between those 2 settings are indeed very close to each other.
But I did not manage to undervolt the PBO yet.
(some setting is overwriting the voltage offset)
(... and those hidden BIOS hierarchy overwrite privileges are not helping at all)
