    In my case, it is on a Rog Strix B550-F Gaming (wi-fi), bios 2806 (only description is "Improve system compatibility", but it does unlock PBO settings and it is working perfectly fine on my end, zero issue so far).

    Now with PBO unlocked for 5800X3D (+ voltage offset that was already available from previous bios), my temp is barely hitting 60C (air cooling, Mugen 5 rev. B) on Cinebench R23. In (fairly recent) games, averages in the 50's (i.e.: SotTR +-49-52C ; Cyberpunk +-55-57C ; Spider-Man remastered 53-56C ** Edit: more around 58-60C when in the streets with lot of people)

    Edit (following @pegasus1 's input): Above testing done with ambient temp @21C
    (and all games @1440p, max settings including RT, no DLSS except for Cyberpunk@quality)

    Enjoy your new cool'n'fresh 5800X3D !!

    Good effort, i use PBO2 as my ASRock bios doesnt support any offsets but the results are the same.
    Temps are good but they are totally dependent on room ambient, thats why its impossible to compare when people just post component or water temps without also quoting the room ambient.

    That is pretty solid on air cooling. Did you manually set the PPT/TDC/EDC down?

    @PC-Tweaker I am curious are you boosting higher now with those changes?

    Strangely, I actually get lower temps if I leave them on "Auto" vs manually setting limits (PPT@101 / TDC@72 / EDC@120, those figures based on the max values read (+1) by HWM after a full run of y-cruncher (Component Stress Tester, all 9 tests), eventhough I hit those same limits whether on auto or manual PPT/TDC/EDC settings .

    That being said, this is considering my following bios settings: SMT disabled, CPU Voltage offset @ -0.05 ; Curve Optimizer @ -30 (all cores) ; scalar@0x (if I put scalar@1x, max temp in y-crunch goes from 80C to +-88C with no real noticeable difference in effective clocks).

    Never went above 4450Mhz (bus clock@100) when all cores are stressed. That being said, our 5800X3D is a strange beast to understand when trying to correlate voltage settings vs max boost clocks, I think each chip have their own sweet spot. Here are some examples following some testing I did:

    - With all the above mentionned settings, my effective max clocks while running Cinebench R23 are within 4375Mhz - 4400Mhz
    - Still with R23, when I raise my negative offset (i.e.: -0.075) or lower it (i.e.: -0.025), I actually get lower max effective clocks (roughly 4250 - 4350) in either scenarios
    - If I leave CPU Voltage at "Auto", then R23 boosts at full effective clocks (4450 on all cores), but at the cost of around 7-8C more on my max load temps

    So basically, at my sweet spot (offset @ -0.05v), I'm losing about 1.5% of CPU performance in order to shave off up to 10% of my max load temps... I'll take it ;)

    My RC20/23 scores peaked at an offset of -0.30.

    Thanks for this info: I've been running a long series of tests on my 5800X3D with the kinds of results you seem to be getting. But I have to note that I rarely ever manage to get R23 scores above 12600, while some people seem to get scores in the 14k region.

    What are these guys using? Ram at 4400 speeds? Old Bioses? Win 10/11 with nothing else loaded?
    I'd like to understand your own results.
    Regards

    RAM makes a difference, if I remember my highest score came with my 3600mhz RAM downclocked to 3000mhz but with tight timings and 1T.

    Cinebench is not very sensitive to ram overclock.

    Zen3 can't do 4400 on the memory, because of the IF. Unless you run it un-synced. But that ads a lot of latency.
    Most people will do 3800 relatively easy. 4000 if you get a good sample and are capable of tweaking several voltages and impedances, just right.

    I'd dearly like to know what your R23 scores were!! At tight timings etc, or not.
    I'm running at 3800, 16-12-19-16-36-56 (originally 3600 18-22-22-22 etc)
    How do people get 14k+ scores? I'm running dual-boot: is that a factor (I wouldn't have thought so)? I'm just wondering if my ambitions are too high, or whether there's an actual impediment to a reasonable score (perhaps my cooler hasn't been re-attached properly - but my R23 temps are below 80C).
    Regards

    Well, I don't know what to say!
    15207.......I'm more like 12507!

    When running R23, HWInfo shows a "Frequency limit - Global of (around) 4310-4390", and so no cores go above that limit. Some considerably lower.
    As soon as it stops running, the limit increases to 4530.

    I'm air-cooling on a Fuma2 (not a bad cooler), I've got a fully-loaded Win11 system (stopping/unloading the antivirus software (2) improves by about 200 points).
    I just feel there's something (on my ASUS B550 Prime Plus) that's stopping it running faster. Maybe the RAM: Single Rank 2x 8GB 3600 Corsair (Micron B-die).

    Any suggestions?
    Regards

    Yes, I tried that: see attached. I DID change the name of the program to PBO_Tuner, to avoid any "" in the program location. You can see the parameters I'm using.
    Maybe I have to wait for a BIOS update: I've seen something on ASUS ROG.
    Thanks for your suggestion.

    It changed my scores but not by much agreed, il have a look tonight as I gradually push my RAM a little, I think having it at 1T might be the stumbling block. My timings are the same as Guru3D used when they tested the RAM (Patriot Viper 3600 2 x 32gb)

    Memory timings?
    I've no idea what typhoon burner is.

    So we can see what timings and settings you have now.

    So we can see what memory ICs you have.
