5800x (and other Zen 3 chips) PBO settings/Temperature fix

[Athlonite]

4.4 all core with 4.85 single threaded is default behaviour

4.7 all core is extremely uncommon


I can literally send you my settings bruh, i could actually save my BIOS settings to a file and send it
Make sure you're on the new W11 happy BIOS as it has other improvements, i'll go take a photo for ya
Make sure to use the advanced menu PBO, not AI tweaker
I also have negative 10 on core optimiser (lower can hurt boost clocks, but help MT. gotta find the balance)


1.15v SOC and 1.4V DRAM let me go all the way to 4GHz on this ram totally stable (but with WHEA errors) so if you wanted to try OCing the ram later, thats how

Bar the ram settings that's pretty much what I have in my BOS settings and yeah already running the 4021 BIOS

Lowering the max boost over-ride increases all core boost
50/100 seems to be the sweet spot between single thread boost and all core
Whea Warnings mean your system is unstable fullstop
it causes stuttering and other performance loss as re-transmission data is slow
@mussles whats your IOD voltage ?

Interesting, i didnt know that

IOD is at stock, whatever that may be

welp there is your problem
under the vddg voltages there is two settings
vddg ccd and vddg iod

set the iod to 1.040-1.060 _imc/ i/o die voltage
set the ccd to 1.020-1.040 voltage for the ccd complex and interconnects doesn't usually need much over stock doesn't really scale with more voltage
and your wher warnings will go away keep those voltages at least 0.040 below Your LOAD vsoc voltage

*warning some boards only control that voltage as a whole number so use 1060 and not 1600 lol

I've been doing this since the 386 days, my brain is *melting* at all these new controls and voltages

How do think I feel I've doing this since the 286 days so my brains actually have leaked out onto the floor and slid away and hid someplace

System did not like those voltages at all, led to a lot of bootlooping and fails

i have run iod at .950 and ccd at .900. don't know what stock is anyway. don't make any difference in stability. I was able to get 4.925ghz stable by setting cores 2,3,4 to -30 in bios pbo to +75. tried to set pbo higher but, 4.925ghz is all it's going to do so end of story here. setting the cores as stated killed mt performance as in 4.2ghz. using ppt=125,tdc=80,tdc=110 every thing else is stock other than docp enabled. 4.85ghz does it for me.
btw i do have a 5900x that I have not used I may sale both processor's and buy a 5950x and call it a day for the next serval years.

interesting you might have one with negative voltage scaling
my research indicates that
-some chips like vsoc and nothing else
-some chips like more iod voltage and nothing else
-some chips scale negatively with more voltage usually above 1.100 VSOC but sometimes iod/>950
iod/ccd is .700 most boards set it to .900 or 1.0 when enabling xmp
amd has made this quiet 'fun'
run zen timings to get your current iod/ccd voltage

 

[freeagent]

AMD has no consistency like the “other” guys. That my guess on why every chip is so different.

Whats the max PBO settings for a 5800x? Because My D15 arrives soon
(As in PTT TDC EDC)

 

[outpt]

about 4.85ghz out of the box. Some tinkering around 5.05ghz is possible but no guarantees.

999 in every field is the max

 

[outpt]

Default for ppt:142,tdc:90,edc:140

Which power settings should I have for a bit above stock? Because I have temp headroom

Take EDC .9x of PPT. Either elevate PPT to 156W, or reduce EDC to 126A.

That’s where the

Which power settings should I have for a bit above stock? Because I have temp headroom

this is where the fun starts, if you are a masochist.

 

[Oasis]

Thanks

Take EDC .9x of PPT. Either elevate PPT to 156W, or reduce EDC to 126A.

so like PPT 156, EDC 140 and then how much for TDC? 90? 100?

 

[outpt]

there is a lot more to it than ppt,tdc,edc, that's just the tip

I Already adjusted my Ram speed/timings, GPU, PBO2 CO and Auto OC

stability testing will tell you if you are going in the right direction.

stability testing will tell you if you are going in the right direction.

Those tuned parts are all stable and because I'm replacing my NH-L12s to a D15 I need to adjust my PBO power settings

 

[outpt]

4.7ghz AC of course.

 

[Oasis]

4.7ghz AC of course.

PBO/PBO2 settings?

 

[freeagent]

PBO/PBO2 settings?

Looks like an all core clock

 

[outpt]

CO core 2,3,4 -30.
