Enabling PBOFmax actually hurt my performance and lowered my scores so had no choice but to disable it.

Don't be so hasty with that thought. The most obvious thing to ask is, are you actually fully aware of the things you have to do in your bios when you enable PBOFmax ? If not, then just enabling it would be a complete waste of time anyway.

I wanted to get the dark hero, but the only way I could get a 5900x was by also ordering a motherboard with it, so went for the normal Hero as that was the best board you could get as a bundle, fingers crossed they add the feature to this board too.

It's a decent board (Wifi) massively over priced but I;ve used it before. The best thing is Shamino on oc.net released beta BIOS which you don't get on the cheaper boards.

Do you mean enabling LLC 3 or similar, and disabled DF C States? I saw a 200Mhz frequency improvement in MT but performance tanked and i have WHEA errors too.

I do. But that also has to be along with rock solid Ram at the same time. WHEA errors can be caused by loads of different things, but in my experience are nearly always caused by ram. It might actually only be a silly thing in ram as well, like for instance tRFC set at 315 when setting it at 320 solves the issue.

I did put memory back to stock auto timings which were looser than a hookers draws but it didn't help perf or the WHEA errors.

Could be a BIOS issue perhaps. Will revisit again once things mature a bit i guess.

Download the latest amd chipset drivers from board vendor or AMD direct for ryzen 5000 cpu's and even if you installed them before installing the CPU re install them, also make sure you use the latest sound drivers for your board.
Installing the latest chipset drivers cured WHEA error's i had when installing the 5950x cpu.
 
5800X @ PBO + 150Mhz Curve Optimiser (-5 Voltage Offset)

MT: 6036
ST: 643

Thanks for the suggestions Matt. I did have the latest Chipset drivers installed, but not the sound drivers. Will give it a go, cheers.

Curious as to how your CPU is configured? as we only have a single point difference :)

Ive done 645 too, but for whatever reason it didnt save.

Running PBO +150 (boosts to 5ghz) - board power limits instead of stock PPT,EDC,TDC etc

Still getting used to the gigabyte bios there is so much more to do in there than with ASUS that iv used for years.

+150, identical to me. Whats your voltage offset? If i go to -10 i have done 645 too but not stable in other applications so have to stick to -5.
 
Multi core - 6051
Single core - 642

5800X PBO, +150Mhz, auto volts
+200Mhz gets a slightly higher single core score but reduced multi

@LtMatt what memory latency are you getting in AIDA64 with the 3600 CAS14?
