5800X3D Kombo Strike or PBO

[va02stephen]

Not sure if it’s officially overclocking but it’s borderline, anyone’s personal experience with this I see online kombo strike setting 3 seems to be the best but can this be used along with PBO or is that asking for trouble? Or is PBO better when I had my 5900x I tried all Kind of pbo setting and literally had zero gains with pbo

On 5800X3D there's no reason to touch the rest of PBO, only Curve Optimizer. Kombo Strike is MSI's less granular take on Curve Optimizer.

No reason to touch limits, unless your cooling is so bad it can't handle 100-120W out of the 5800X3D.

No reason to touch scalar, you're not allowed and will be kicked down to 3.4GHz.

No reason to touch boost override, you will get kicked down to 3.4GHz if you try to increase it.

Treat it like a locked CPU, get your undervolts done with curve optimizer and you can just get on with your day. Goal is to get to a steady 4.45GHz under all core load, and hit 4.5-4.55GHz on single core load.

Try some AGESA 1208 BIOSes, MSI might have restored access to the real Curve Optimizer.

Thank you that explains it better for me to understand, what is the correct way to undervolt with the curve optimizer

I was half asleep last night when I replied as it was late here haha, I enabled kombo strike 3 yesterday to try it and in monitoring software on timespy cpu test I noticed I achieved 4.55ghz I guess this is best as it gets? Or will I still get better performance undervolting with curve optimizer

Kombo Strike is literally just Curve Optimizer but limited to 3 options, -10, -20 and -30. Sounds like yours is reasonably stable at -30 then.

4550 is the max freq unless you're willing to dive into the quagmire of BCLK overclocking. Depending on the nature of the load, you may be able to sustain 4550 up to about 3 cores active, but in practice things are never that simple so 4550 for single core, basically. Good result, if you can also hold at 4450 in all-core (ie. Cinebench R23).

just ran cinebench r23 with kombo strike 3and i got a multi core score of 15112, i used msi afterburner to monitor it and all cores where sitting at 4450mhz so i guess this is pretty much as good as it gets? every now and again it would drop to 3560 but i guess this is at the point of transition where it starts to render the image again.

single core was 4450 with spikes to 4550mhz

15100 is a good score and right on for 4450. Sounds like you're all set

again thank you for helping me oh forgot to mention as well max temp was 74c which i was surprised at as i heard these are known to run really hot.

they do run hot, but higher curve optimizer offsets (-20 to -30) significantly reduce thermals. Depends on hardware, but it's pretty common to see high 80s when stock, down to low-to-mid 70s after -30. 74C is round about where I am as well on -28. Pretty dang normal.

Similar to Ryzen 7000, games will run much cooler than R23.

Just wanted to add from my own experience -30 isn't optimal, my curve atm is -20 -10 -20 -10 -20 -20 -20 -20 and it boosts like -30 but performs a bit better I find in some games. The -10 cores are the star cores on my cpu.
