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

[outpt]

ppt,edc etc., are at stock settings as stated in my post. Only modification are temps and pbo boost settings along with voltage settings as posted.so what’s wrong? the system likes it and I’m happy.

Well, there are good settings and there are better settings. While edc<90% of ppt will do a fine job throttling the cpu, I don't think it is the intention should you want to get a good score.
PS: llc, scalar, curve, optimise, pbo - all bad, overclocker trash.

PS 2:

125w PPT, 90A EDC

vs previously established configurations

105w PPT, 95A EDC

or 10% higher

115w PPT, 105A EDC

are good checkpoints.

Essentially he landed on the same settings(120w PPT, 110A EDC). I haven't seen any guidelines on TDC, so his findings are uncontested.

Away from the house I have not gone back at this point and plugged in the ppt and so forth settings I was using. The main point is that the voltages I changed made pbo usable for me. There are no more system crashes. Not threw testing at this point. There are such things as using the computer.

Gah i keep getting confused since neither of you have profile pics, and your default colours look the same

good work on sorting it out Outpt

If you could fix moving picture avatars, I have a good solution.

fixed my temperature problems! I can not believe that my brand new 240 aio has been dead out of the box i now have my corsair h60 a 120ml cooler installed and it cools like a champ.
i am major pissed-off. Corsair from now on.

 

[mtcn77]

It could be the ihs-coldplate incompatibility, straight cut vs convex, you never know...

 

[AleXXX666]

You can simply tune the settings to suit your needs and temp preferences

In my case, i get my full 5.05GHz single core boost, and lost only 75MHz off my multi threaded - this DOES seem to vary board by board, so you gotta adjust.

single core is nothing but benchmark, i like 8 HT cores @ 5 GHz beter

yeah... because that's possible on zen 3, sure.

 

[gerardfraser]

Not common but possible for sure. 5800X 5000Mhz all 16 threads all core overclock with HWinfo64.
I would never do what Alexxx666 suggest he is running ,half CPU at higher speed but people actually do.The higher speeds are for e-peen and do nothing in reality.5800X is a beast at default for CPU.

Playing video games at 5GHz is one thing.. what else can it do at 5GHz.. everything?

" This would not be prime95 stable or even be able to run P95 for 1 minute.It is a PC game."

yeah, nah.

 

[freeagent]

These things are just big calculators.. what's the point in running your calculator fast if its just going to spit out bad answers all the time, or worse it cannot compute

 

[gerardfraser]

" This would not be prime95 stable or even be able to run P95 for 1 minute.It is a PC game."

yeah, nah.

Oh so if you can not run prime95 stable then CPU is no good ,yeah lol

 

[Mussels]

Oh so if you can not run prime95 stable then CPU is no good ,yeah lol

he says its not even stable for ONE MINUTE
and yes, if its not stable in prime95... its not stable.


these pointless comments about someone doing suicide runs at 5GHz with unsafe voltages and an unstable machine are really pointless, and derailing the thread from the PBO topic

Lately I keep brooding over it more than I'd like to admit. It's supposed to be a fix for the 5800X, but being unhappy with 5900X thermals lately I thought why not take a crack at it. After all I only have MT performance to lose, since on the bigger chips the power limits don't really govern ST performance much at all.

Stock thermals were alright but Curve Optimizer made thermals.........interesting, to say the least, and not in a good way. I thought I'd start cutting down on the limits a bit, so I tried 130/90/120:

It seems like Curve Optimizer wasn't the catch-all solution AMD promised - it improves perf all around but only reduces temps on ST. So for cooling down ST we need Curve Optimizer, and for cooling down MT we still need PPT/TDC/EDC control. Unfortunately I wasn't able to do much about ST since the two usable ST cores run into a wall at -2 and -7.

But seeing the results I'm a happy camper so far. In the next few weeks I want to see if there's still room for refinement.

I found that another benefit of reducing power limits is that it reduced the core temp deltas a little bit. At stock with CO, Core 8 is almost always 13C hotter than Core 7 in an all-core load.

You should try a new generation Thermalright cooler.. the coldplate and mounting pressure are fantastic. I saw a 6-8c drop by switching from LGMRT to FC140. And I thought LGMRT was godly.. Also the AMD mount is nearly identical to Noctuas.. I think. Very easy to install.

Wow FC140 is now available in white.. dammit looks good.

And I saw the PA120 when I was buying FC140.. I still might buy it for my 5600X. I like it.

I only have 144mm of cooler clearance otherwise I would've switched to the U12A long ago

I can only fit the Fuma 2 (not really better), TF Silver Arrow 130 (not better), Dark Rock TF (not better), or any of TF's 120-on-tiny-heatsink "Mini" coolers (definitely not better). And none of them can provide airflow for the B-die unfortunately

 

[outpt]

after cooler change and some pbo + co tuning 72C.

72C in Bench or Stress Test? I can do "72C" at 142W too, it becomes 78-79C when I actually stress test.

CPU-Z MT benchmark lasts like a total of 5 seconds

i will take care of that brb

not to bad. no temp. limits. on a Corsair H60

Thats decent. What about Stress Test in CPU-Z for 5-10min?

 

[outpt]

here's what i have done: PPT=115W,EDC=90A,EDC=110A,PBO+25mhz
VDDG CCD 0.900V,VDDG IOD 0.950V DRAM 1.370V
Curve Optimizer -3,-7,-15,-14,-15,-14,-13,-14 this is for cores 0-7 not though here.
CO and PBO do not play together thus the +25mhz
Memory at stock
Most up to date bios for mother board.

I'm running a 5600x I've been scoring 11,720-11,660 on all core and only 1,502-1444 on single thread. I'm only running my ram at 3266mhz it's only 3200mhz ram Corsair Vengeance pro RGP 16Gbs. I think my Infinity fabric might be a bottleneck now ?
I seem to be stuck at 4,730mhz all core, and single thread 4848mhz. The temps are only 73C on all core and only like 53C on single thread I'm on an AIO corsair H150i elite.

i run my 10700K 24/7@5 GHz. why use it at stock, lol. 0,3 GHz free boost, but still!
