But i'm back to 3333@14 no difference in CB still peaks at 4.3 XFR


3466Mhz and 3600Mhz have been very achievable on my G.Skill Flare X RAM kit and it's not even on the QVL list (made for gen1 zen). Have you tried the Ryzen DRAM calculator? I'd leave any "ohm" setting on auto.

i've been bootable in cl16 at 3400 for quiet sometime but its not stable, needs 1.41v dram and slower than 3333@ 14 1.35v

Before 2.00, my CPU would turbo up to 4.5-4.7Ghz inside of 3DMark (obviously certain cores/threads only) - now the max seems to be 4.35Ghz. Overall with PBO, multithreading performance has gone down as WELL as single-threaded. I've tried many, many, settings in BIOS, power settings in Windows, making sure background environment is the same, etc.

However, simply locking my CPU down to 4.2Ghz nets 1950 in CB. Also, now I am actually full on STABLE at 4.3Ghz. It seems like there was a lot of under the hood tweaks with how power gets delivered to the CPU. RAM voltage seems closer to target now too. Overall good, but I kind of miss my PBO lol

Hi,
If PBO is enabled and you want to get the best CPU performance, then the CPU Offset Voltage should be set to -0.1V.
So it was with the BIOS version before ;)

Offset -0.1 *used* to be extremely stable, and right before 1.62 came out, my PC basically wouldn't boot anymore. Just one positive click makes it stable again, so I did two "+"s

Did you get it wrong ?
If you set only PBO to enabled, an offset of -0.1V was automatically made. Less voltage, less temperature, boost goes higher ;)

-0.1v is what made our systems unbootable in 1.50

And manually setting it to -0.1V hard lock the system with E6 boot code

Are all the options from 1.35 beta bios back? Some were missing with 1.52 like offset not working with PBO enabled, pbo scaler options etc...

I really don't want to update if I don't have to. But I have 3600 samsung b-die ram which I can't get stable. So I run at 3400 cl14 with 102 bus clock.

Going to try the new bios, but the past few revisions I have not been able to use PBO. It locks to -.1v and never boots ever. Everything else with this board has been amazing though!

-0.1v lock has been fixed since beta 1.62 just remember to change the value because you exit bios as it still loads -0.1v

-0.08 to 0.07 is a good number
