Overclocking a new AMD Ryzen 9 5900X CPU

Banditt1976
Level 8
I have a newly upgraded system with an AMD Ryzen 9 5900X CPU and ASUS ROG Strix X570-E Gaming motherboard. This is my first venture into overclocking an AMD processor. I know how to set the OC in the BIOS for all cores: currently I have it set to 4300 MHz with PBO on which keeps all cores at the same speed with no single core boost anymore. Is there a way to raise the base clock to 4300 MHz and still keep the single core boost at the default 4800 MHz or higher at the same time? I have a Thermaltake AIO cooler for the CPU which keeps idle temps around 48 C and can handle a lot of all-core load tested using Cinebench r23.

To set 4300Mhz

When you overclocking manually online:
1) set 4300 (Core Ratio) 43)
2) set 1.4 or 1.5
3) increase frequency upward until it is unstable and than lower the 100Mhz and repeat the increase voltage again to be stable

Please use AIO or water cooling system
Sincerely,
Legolas

I have overclocked Intel CPUs for years, so I already have an AIO cooling system. My question was not about setting all the cores to 4300 MHz stable, which I have already done using various stress testing apps. My question was basically if there is a way to move the Base Clock from 3700 MHz to 4300 MHz while still keeping the single core Boost Clock at the stock 4800 MHz. With no replies to this question it is pretty much what I already knew. I either have to leave it at the stock Auto setting which has the Base Clock of 3700 MHz with a single core boost up to 4800 MHz. I ran some tests at the Auto setting and the Boost Clock rarely went up to 4600 MHz, much less 4800 MHz. I have decided to keep the all core overclock at 4300 MHz and forego the Boost Clock as I feel my system performs much better overall this way.

Have you set up PBO and curve optimizer?

From my experience, curve optimizer can help to boost frequency of individual cores while correct PBO setting helps to lower the temperature a bit and keep the clock frequency.

It can help the single core and all-core frequency.

Good luck!

I finally setup PBO and Curve Optimizer properly today after watching an excellent YouTube video on the process. In the end I was able to get 4700 MHz single core and 4350 MHz all core frequencies with stable temps as well running various benchmarking apps. The single core sometimes even bumps up to 4850 MHz during the single core benchmark of CinebenchR23. This was verified by having Ryzen Master running in Basic View at the same time to show the current frequency in the status window.

This is good.

Would you mind sharing some of your benchmark results in single core and multi-core?

I ran so many today I will have to run them again and record the results.

CinebenchR23: single-core=1605, multi-core=21086
3DMark Time Spy: Total score: 14553, Graphics score: 14550, CPU score=14571, (CPU reached 4950 MHz at one point)
Novabench: 5229
GeekBench 5: single-core=1735, multi-core=15453
Prime95: Stress Test with no errors

AIDA64: (No idea what most of these mean but these results are all in the top 5 of the comparison readout)

Any others you want me to test?

No, thank you.

Your results are pretty good.

I have a 5800X and waiting for a 5950X and I shall tune up my system after once I have received the new CPU.

Cheers,

Hello to everyone,
I also have a 5900x processor. i just want to make pbo or oc to improve game performance. Which would you recommend and how would I do it? It was mentioned that there is a video on youtube can anyone give a link? I also use 2x16gb pny xlr8 brand 3600mhz cl 18 ram. how do i do oc for ram. Thank you in advance for those who reply.

Hello,

What is the PC's intended purpose?

Which motherboard?

Your memory is already overclocked, 3600MHz is beyond stock specification (PC3200).

You can enable PBO from the Extreme Tweaker Menu

Check memory stability before attempting to OC further. Use a memory stress test such as HCI Memtest Pro or Karhu Ramtest.

Gains on this platform are very limited, depending on the stability margin on the memory kit, you can try opting for a lower CAS latency.
