Well if your on water why not try 50/51/52 and see how it works. All core overclock is not need but if you like the big numbers then overclock is fine.It will not make any difference in performance with a RTX 3090 running with PBO or 4500Mhz-5000Mhz.Easily testable with your setup.

AMD Curve Optimizer and then new BIOS release soon AMD Adaptive undervolting will be what you want.

You can set whatever you want and check stability. First off there are two different areas in all BIOS for PBO stuff.

In the AMD overclocking section ,go to PBO and set your AMD curve optimizer up- this will give you normal boost clock EG:5800X boost to 4850Mhz
In this section you can add up to 200Mhz it is the same for all motherboards EG: 4850Mhz+200Mhz=5050Mhz

If you want higher CPU boost clocks then you need to goto the second area for PBO settings
Advanced CPU Configuration set your PBO boost higher than 200Mhz like in the first section on MSI motherboards you can go as high as 500Mhz

To get 5100Mhz then set PBO here to 250Mhz
So 4850Mhz+250Mhz= 5100Mhz
save and test.

ASUS has DOS Overclocking also,not sure about your motherboard

 

Thanks for all the info, but not sure where to find these settings.....

- So what you're suggesting is that I set the Ratio back to Auto

Not sure where curve optimizer is, is that the Q-Fancurve?, on the Extreme Tweaker Setup I do see PBO but with the following options:

- And i suspect the second PBO settings is under Advanced/AMD Overclocking? shown here: (but there's no option to input a value)

- And what about Digi+? do I set all to Auto? I'm currently at LLC3 and 130%:

Thanks for the help!

 

I use the BIOS only settings on the TUF X570-Plus Wifi; your BIOS is almost the same, but better and called Extreme Tweaker in the settings. I love it. I'm getting extra points in Cinebench R20 Multi-core at around 4858 and 499 Single Core with 6 out of 8 cores getting to 4.392 MHz with stock Air Cooler and other two cores at 4.367. This is for a 3700X but yours will be MUCH better and faster; the same principles apply. I never mess with Ryzen Master in Windows and it auto-throttles all the way up to max OC and all the way back down when not in use. You do get higher MHz out of the CPU. The 5000 series will be able to use the new SAM features, also and Asus just released a bunch of new BIOS' tonight. It is definitely worth it for 6-10 BIOS settings that I I outlined here and also made a video on it for Asus mobo's:

Read this thread for your Asus Mo0therboard. There a also a video

woah! I did not know about the 'Profile Switcher' feature, that's gamechanging for Ryzen, if I'm understanding it well, we get the best of both worlds.

Edit: looks like profile switcher is only available on the Dark Hero board..... back to trying to OC PBO.

 

Since you're mainly gaming, I would suggest just enabling Fmax Enhancer and letting your CPU boost to higher clocks for the lighter loads (gaming) vs all-core OC for heavier multi-threaded applications (production work). My 3900X could barely scrape past 4.4MHZ single core, but Fmax Enhancer lets it boost up to 4650-4675MHz single core and brought my multi-core clocks from 4000MHz to 4200MHz, while also dropping my load temps from 55-70C down to 45-55C (custom loop).

I'm sure the Profile Switcher feature will eventually get to the other Crosshair VIII boards (I have the Impact myself), but will probably take some time.

The 5000 series CPUs are fairly new, so Asus will likely go through many BIOS revisions to get it more stable with higher Infinity Fabric (IF) clocks. Hopefully you can hit 2000 IF/4000 Mem clocks without much hassle, but if you're able to hit 3800CL14, you are already at the peak of IF/mem performance.

I highly suggest going through this thread or at least reading the latest posts if you haven't already:

Awesome info! I do have Max Enhance on, I'm trying to figure out what scalar to use... 2x or higher. I also updated my BIOS last night to 3003.

 

I'd start at 4x and use 100mhz override, I've seen others go up to 10x and 200mhz, but I personally saw less gains with the higher options.

That said, Ryzen CPU OCs don't show much real life benefit outside of the extra clock boosts granted by Fmax and PBO. You'll see better performance gains by increasing IF + memory clocks and tightening up your primary/secondary/tertiary timings using Ryzen Dram calculator.

Like I said last post, if you're already at 3800 14-14-14, there's not much more to gained by going to 2000IF/4000mem.

 

Your ram is perfect the way it is as long as your not getting WHEA errors or other errors. You should also to able to hit Cinebench 650Score in single thread on your CPU.

Well the issue is that my BIOS does not have the Curve optimizer yet... or I have no idea where it is.

 

Awesome,awesome CPU I hope you find what you want but simple truth is the 5900X out of the box is great as is and AMD know what they are doing.Do not bother wasting time on Cinebench scores LOL J/K

Going back to the post where I suggest trying overclock ,did you try for example.
Amd 5800X All Core 5000Mhz Assassin's Creed Valhalla HWinfo64 on
Amd 5800X All Core 5000Mhz Assassin's Creed Valhalla HWinfo64 on for anyone interested - YouTube

 

I wish I could get to all cores at 5000mhz.... so far i can only get 3 but i'm trying.

 

Do not give up,it is possible.
