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

[DemonicRyzen666]

Using 200/140/180 with my 5600X capped at +150 can put out over 140w PPT using Linpack Xtreme. The most I saw was just over 150w PPT on 5600X. Static OC should be easy on that CPU.

Well, I tried 1.375 at 4,750mhz it only pulled 117watts on PPT.
Temps only went up 4C
With PBO2 On I can't get to let it go past 107w on PPT
Maybe my chip just needs to go under LN2 lol

I found my issue had turn on something wasn't hitting near PPT limit. Now I'm right at it now. bumped right into 135 watts a 74C.

Apparently, I had to turn on this custom setting in the bios "CPU_VDD_SOC current optimization" this wasn't in earlier bios settings.

^ This is with it at auto

all PBO settings are the same on both of those.

Has anyone tried flashing back to the previous bios that boosted better? Or should I not try.

I did.

You hit 150w PPT with PBO?

Nice.. I hit 150w at 4700 static,

Most impressive..

 

[ntdouglas]

Did you go back to 4005?

 

[DemonicRyzen666]

I did.

You hit 150w PPT with PBO?

Nice.. I hit 150w at 4700 static,

Most impressive..

I can probably hit higher, but I have no idea what these settings do as these came up in a bios update and there isn't anything in the Manual about or on PDF's about it.

Dude.. I would be impressed if you could.

Yeesh 150w on a 5600x? I found if I set anything higher than 130w 75a 100a my cpu stops hitting 4.85ghz under stress, 200w 140a 180a p95 hovers on +-4.8ghz for the first test, changing the values back to what I have it stays 4.85ghz all cores p95 first test, second test my settings maxes out around 124w. Only those 3 values were changed.

Now testing with override + offset voltage and it's maintaining boost with about 1.256v vs 1.375v auto, thinking this is the way to go for long term pbo use, passed first round of p95 @ 4.85ghz all cores and 50-51 degrees, second round wattage is lower- 105-107w vs 125w on auto, 66-67 degrees and passed all workers without issue.

Single and multi core scores are down in cpu-z now, on to more testing.

Yeah it’s pretty intense.. it was a static all core clock of 4700 running Linpack.. pretty brutal. Probably close to the limit of what an air cooler can deal with on such a little slug.

Scaling above 4.6GHz is terrible to 5600X. At -30 CO and only +50 pbo at 76W it runs at 4.575-4.625 depending on temp. Removing pwr limit it runs at 4.7 AC using 84W. Running allcore 4.8GHz@1.32v it uses 115W+.

So far they just freak out and reboot when amps and temps get out of hand. I haven't run a static oc long enough on these Ryzen's to cause any noticeable damage.

You have a beautiful chip good sir

Yes, I'm lucky, ram bin is mediocre though Coming from a terrible binned 3600 (4.1GHz@1.25v, stock allcore 3.925GHz@88W vs 4.7GHz@1.27v and 4.3/4.6GHz allcore stock/-30CO@76W on 5600X) I felt I deserved it

Maybe if you feed your cpu a high voltage, I ran my 3600x @ 4.2ghz 1.25v for years, no degradation, I'm running my 5600x @ 4.65ghz 1.25v no issues, p95 stable.

The 7nm process was designed for 1.3v, you will not harm a ryzen feeding it 1.3v manual.

 

[DemonicRyzen666]

Oh, I have load line calibration set to mode 8 on cpu and SOC/NB in the motherboard and the voltage set to "AMD overclocking" on both of those with curve on (-30/-30/-10/-30/-30/-30). My all-core load voltage is/was only at like 1.244 for 4.4ghz in prime95 last time I looked. I might have also had a negative offset on a one point too. The crazy part about this is the temperatures haven't really changed at all.
Cinebemchr23 still around 72C
Prime95 small FFT still around 81C

Changing the wattage does change some things but I keep bumping to one thing or another either EDC or TDC
remember I said my chip was rated golden by CTR. this chip will do 4,750mhz but it will be 1.375 volts I can't even get 4,600mhz without 1.325 volts on a static overclock how is this golden?

I've not overclocked since my 3600x and want to take my 5600x for a spin is PBO the preferred way to go now Instead of ryzen tuner?

PBO+CO. If you have a good cooler I would try to max out PBO, if you have a okay cooler or budget cooler prioritize negative CO. PBO+CO is superior to allcore OC on my 5600X.

Best I can get with allcore OC is 4.7 and that uses 85-90W (1.26V) in CB23 getting me 12050 points, with PBO I can get 4.85 single and 4.7 allcore, in CB23 I still get 12050 but consumption is 76W (1.2-1.22V during load )

EDC has negative gains over 100a so set 130w 70a 100a limits for 5600x if you have a good cooler (TDC 60a and EDC 90a are the default values).

After not getting anywhere with the offset voltage (it will happily run on a lower voltage but performance is lower) I started playing with CPU LLC and modes 1-4 don't offer any performance increase modes 5-8 offer a load voltage reduction with 5 and 6 offering near identical to auto performance 7-8 offer further reduced voltages with only multi core losing a few points, single core still high through all tests. Mode 8 caused a BSOD with my new curve.

Mode 6 looks like it runs the cpu around 1.34-1.35v as opposed to auto which hovers around 1.375v with PBO.

I can't break 9,500 in cinebenchr25 with those settings. 130w 70a 100a

11,901cb r23 multi core with 5600x @ +200mhz offset PBO -11 -6 -6 -10 -16 -11 curve and 130w 70a 100a limits.

If I go above 100a EDC my cpu stops holding 4.85ghz in p95 blend first round and doesn't gain any extra speed when the load increases but EDC will happily go as high as 132a when uninhibited but I've noticed the cpu doesn't gain any performance as a result.

I get more of a performance boost from a tiny increase on the fsb.

What bios version are you running? 1.2.0.3c is the best for 5000 series cpu. Also the less voltage you give the cpu the slower it runs, when I run mine @ 1.25v with PBO I lose over 600pts in the cpuz multi core bench.

PBO + CO, or a static all core clock at an efficient setting (ex: mine at 4.6GHz all core needs 1.21V)



My brother got me to install his 5900x yesterday, it's annoying how much colder it runs than my 5800x, despite the higher wattages

debating to get a regular old 5800x or wait for the 5800x 3D to see how limited it's PBO really scales.
Microcenter about 20 miles away got the 5800x for $319.99 Amazon also has it for $339.99
Or start getting a custom water setup for a new build ready.

Get 5700X or 5800X3D, not 5800X

I'm not sure if I should post this here or if a new thread should be started, but yesterday I watched a video (that I link to here) showing that if you set CPU Boost Clock Override to -200 in the bios, so that it runs at 4650 mhz, it lowers the temperature by a lot, so I tried it using Cyberpunk 2077 as a load. With a Noctua NH-D15s cooler and PBO power limits set to stock disabled settings (142, 95, 140) and with Curve Optimizer enabled and CPU Boost Clock Override set to +200, my 5800x ran at 78c. Next I tried only changing CPU Boost Clock Override to -200 and my 5800x's temperature was 68c, so 10 degrees cooler (at CPU Boost Clock Override set to 0 it was 74c). The performance wasn't noticeably different, just a few fps slower, so I thought I would mention this. The video's thumbnail shows -20c, but for me it was -10c, but other than that I though it was useful information. I do realize that lowering PBO limits will allow single core loads to boost much higher than setting boost clock override to -200.
As for me, nowadays I'm running my 5800x with PBO power settings at 142, 95, and 140 with no boost clock override, even though it's stable at +200, and tuned curve optimizer.
