Looks like none RUclipsr managed to get their hands on this board yet. If you still have that board you should upload a full review of it, something complete; covering the whole board also its memory overclocking capabilities.
It still needs some work in the Bios, but it does 2000MHz IF clock easily. I've only compared it to the x570 Tomahawk, but memory and PBO tuning are better on this one (as it should be).
Very very good video !!! thank you very much for all information !! But I have one question : on the video for dynamic OC switcher and the 5900X , u set only 35A to threshold for the 5900x , and u set 75A for the 5950X , , why such difference between the two cpu ?
Thanks for the kind words. The value for the threshold is not CPU SKU dependent, but will in fact be unique for each system. That's because the threshold is used as a trigger to switch from manual OC to PBO. To know the right value, you must check at which point the multi-core frequency set by PBO is lower than the multi-core overclock you can achieve manually. The higher this point, the higher the threshold value. So, with air cooling, it's very likely that this value will be low. And with liquid cooling, the value will be high. I don't think there is much value in comparing threshold values between CPUs or even between systems because it depends so much on the real-world overclock you can achieve with a specific system.
@@SkatterBencher thank you very much again for all these explanations !!! thank u very much. I ve just a small question : how do you check the threshold ? with the software hardwareInfo for example ? it s when you say : "you must check at which point the multi-core frequency set by PBO is lower than the multi-core overclock you can achieve manually"
That's correct, HWinfo will help you figure out the correct setting. You can watch from 3:39 of this video. Basically, first you have to know what is your manual overclock. Then, check when the PBO frequency drops below that frequency during a workload (use prime95 to gradually increase the workload to see frequency drop). Then check in HWinfo the CPU current when this happens. That's your threshold.
I've been using this board with a 5900x for about 2 months now and the reason I bought the board was DOC. "Unfortunately" this is completely unneeded, as you can configure PBO for a much better result. At this point, PBO is maintaining 4.65GHz in Cinebench R20 + R23, even over a 30 minute run. In Small FFTs in Prime 95, it sustains 4.5 - 4.55GHz and it boosts up to 5GHz when gaming and I see max boost clocks of 5.125GHz if I leave it idle with just background tasks. When using DOC, I can't get it stable for Small FFT above 4.45GHz and with worse voltages and for Cinebench, up to 6.75GHz on CCD1 and 6.25GHz on CCD2. PBO won and it both sucks and is awesome at the same time.
Hi PoorGreekBuilds what s your PBO parameters ? my 5900x on dark hero with PBO enabled (but only PBO , no others parameters actually) maintains "only" 4.4 Ghz on all core on prime or cinebenchR20/R23. With this feature , I can get 4.6Ghz on all core (with VID 1.32V and actually I didn't try to get higher as the 5900x is already a beast on stock ! ) , so for my Rig , this dynamic OC swticher is a great feature. Perhaps I can get better with PBO (and curve) but actually this DocS is very good for me.
@@fredericchambon3820 currently, on the latest BIOS, my PBO is: PPT: 320, TDC: 255, EDC: 255, Scalar 10, Boost Override 125 and in curve optimizer negative 10 on all cores. Also I have custom liquid cooling and this allows me to boost higher. As I'm sure you know, it's very temperature sensitive. Let me know if you give it a try 😁😁
Finding a way to benefit from both a manual all core OC and PBO is such an obvious problem/desirable feature idk why AMD and more mobo designers aren’t coming up with solutions like this. It’s a shame this is only available on the dark hero. Hopefully next generation this will be a standard feature.
Yes, it will work fine with PBO 2 and Curve Optimizer. Dynamic OC Switcher just switches between the PBO mode and OC mode. PBO mode = your PBO (with any curve optimizer) configuration. OC mode = your manual configuration.
Thanks for this vid...but its just a cut up version of your previous video when the board launched? (lol i guess you made it for the guy that said you went too fast) im starting to fine tune this and loving the results. I feel like someone needs to test and explain how ppt edc and tdc limits affect performance. Seems like auto sends too much power and thermal throttles sys. If you scale them back manually...scores go up. if you scale back too much performance goes down and so does temps (obviously). Lol we need further info on this behaviour.....for those of us that cant sit here all day testing pbo limit variables.
Correct, it's a cut up version from a previous video. I figured some people might want to know about an OC feature without having to look through videos to find it. I'm not sure these small OC feature videos will be popular though ... time will tell
@@SkatterBencher honestly, your original video was fine and explained the majority of it. I used it as a reference and am happy with the results 😊 Thanks again
Can I pay you to send me email instructions to get dos working on my dark hero and 5950x? I tried your settings but It crashed… Im doing something wrong. I can paypal.
After go’ogling around I realized that Simmy Krotiel’s Bigger Blueprint was modified and you can make it bigger even faster, yep, what Simmy suggested before was pretty good, but the new stuff teaches how to make it up to four more inches bigger
Exceptional explanation. Subbed.
Just bought this board, and I'm looking forward to get to know how to get the most out of it.
Best of luck and enjoy!
Amazing content dude, hope you get more subs
Thanks!
My 5950X comes tomorrow and I cannot wait for greatness!
Enjoy! Ryzen 5000 series are pretty neat :)
Can't you use the temperature threshold to force it to kick back to PBO for OC without blowing the temp limit?
So DOS OC stands for "Dynamic Overclocking Switching Overclocking"?
😂 yes :)

Does it work together with PBO 2 and Curve Optimizer? How to setup this then?
Yes, it will work fine with PBO 2 and Curve Optimizer. Dynamic OC Switcher just switches between the PBO mode and OC mode. PBO mode = your PBO (with any curve optimizer) configuration. OC mode = your manual configuration.
Really with they would add this to their boards with the "Ai Tweaker" options
This feature required a PCB-level change from previous motherboards, so it can't be copied over easily to other boards

Title is wrong, there is no such thing as a Maximus VIII Dark Hero, it's Crosshair VIII Dark Hero.
