R7 5800X PBO2 QUESTION

[nicklog]

Hello

My 5800x manages to run all core -30 in curve optimiser this is how I got my best score on r20 CB so far.
After I saw its stable i tried to get some Max CPU boost clock override.. tried from 1 to max but when running CB R20 there is no difference whatsoever on my clocks, they get stuck on 4750mhz (same like when it was on 0 clock override)

Any ideas what's that about and how could i slowly test to raise my clock?

EDIT:
When I'm on idle i see some cores jumping on 5ghz . But while i run the bench they have a cap at 4750

Mine does basically the same. For all core workload like Cinebench I think it's basically hitting the power limit, so it can't boost any higher than what you're seeing (although if you can keep it cooler it probably will).

What voltages are you guys running yours at?, I'm stable at 4.675ghz but when i tried 4.7ghz it wasnt (using cinebench to test stability), my core voltages are at 1.35. Admittedly i didnt try and higher than that as temps were 70-75*C under load (using EK 360 AIO). I did all my over clocking in the bios though (Asus X570 Strix-E)

Cheers

I just use the curve optimiser, - 25 offset, ends up at about 1.31V for 4.75 GHz, sustained in Cinebench, I think. Also lets the CPU keep the 4.85 GHz single core and lighter workload boost that way.
