PBO2 -20 +100MHz = 5GHz
( PBO did nothing for my 3800x or 3950XT - old BIOS )
All of my other PBO's var's are Auto.

My CB23 increased over 1100 points.
( to 23k+ )( CO all core -20 )
Time Spy CPU score up 100.

AIDA says my latency suffers thou ...

[ Edit ]
Closed P95 after 9+ hrs error free at CO all core -20 except for core #21 at -15.
But, when I launched the HB benchmark ( here ) I rebooted.
Moved core #21 to -10.
Gained 5 seconds on my boost mode score
( encoded 1806 frames in 166.40s)
I lost 900 points in MC CB23 ( down to 22,200 ) with core #21 at -10.
AIDA boost hits only 4.775 GHz now
Time Spy CPU lost 200 points - despite logging my CPU at 5051Ghz.

The OCCT SSE test did not catch my undervolt instability.

Let the chip do what it wants ...

[ Edit 2 ]
PBO took a chunk from my MC CB23 All Core OC ( 4.6Ghz ) also.
No more PBO for me.

OC is always a balance for me.
PBO ? -- yea I tried it --- tastes bitter

So I’ve updated the bios on my board to the latest release from earlier this month. Basically started from scratch again.

just to be clear I only care about single core boost as this is a gaming pc and why I bought the 5600x version.

I’ve included 2 pictures 1 with cb23 multi thread and the other single thread. Both show hwinfo details, I reset them after running each test. Zentimings is on second picture.

I tested each core with curve optimizer for 2hrs or if they crashed before time limit (then adjusted CO)with prime95 small fft+avx.
Core 1&2 are preferred cores. I’m currently testing all core stability.

I also used boostTester and every core but the 2 preferred stopped boosting till about 4940-4970ghz, cores 1/2 stopped about 5030ghz I think it was. So I stopped increasing boost.
Cooling: ek 360mm Aio

settings:
CO: -16, -3, -7, -17, -17, -20. Cores are in order 0-5.
PBO: +375 MHz offset
Power limits: manual. I used the same watt and amp limits as the 5800x 125w tdp processors.
Scalar: 3x

everything else is pretty much on default. I noticed all core tops out at 4.6ghz. Apart from scalar anything else that would ensure higher consistency and sustainable single core boosting? You see anything out of the ordinary or something I can improve?

It'd be more helpful, if you post a screenshot of HWInfo (6.40) sensor panel during cb

For your curve optimizer, just to confirm, those are all supposed to be negative numbers correct?

Can you use HWInfo graphs to show your frequency over the course of the test?

Yes, it’s all negative. My screw up, I went ahead and edited the post to correct that.

I don’t have the graph, but I did watch the multithread test since it’s a lot shorter and that ranged from low 4,661 to high 4675mhz effective clocks in hwinfo.

after this new all core stability I can take a graph reading.

overnight sometime after 6hrs+ of no errors, I woke up to over 2k OCCT errors. So I began a new test, I raised the curve optimizer on the last core from -20 to -17, since that seems to be the outlier. Every other core crashed at that low of an offset.

the test I’m running is occt avx2 extreme for 24hrs, then I planned to run prime95 test.

I don’t have the graph
Can you make a hwinfo sensors screenshots DURING benchmark, not after it finished. You may just hit PrtScr, while running it, then paste screen copy to the Paint editor and save file as png. This is important, because there's lot of meaninful info besides effective clock.

Our PC's are pretty much similar, and initially I thought you've hitting thermal limit, then I've made two cb r23 runs for comparision purposes, one at the idle temps (when browsing, etc.) ~ 21-22° mb temp, and another after 30 min of gaming, ~24-25° mb sensor, in attempt to reproduce your envir. conditions. PBO settings and other data in screenshot below. (hwinfo64 screens with 25°-ambient temp were lost in clipboard, so I've added from memory just eff. clocks)

What first came to mind, was that your Curve settings seemed too tight, since as you said, when running BoostTester (which is an ultra-light load) none of the cores except the best two, reached 4980 MHz.
I for my part, tuned CO so that all cores reached Boost Override value in it,
though your approach is reasonable too, and the main purpose of Boost Override might be to cap those best cores indeed, while the rest should not necessarily run as high. Rather the opposite, due to their usually inferior quality.

Summing things up, I dont think you have much to do, unless your stability criterion change from "passed Y-cruncher, OCCT and prime95 - small data set, launched together with some heavy game".
What I would do for sure is, either decrease BoostOverride to lets say 300-325, or tune the Curve, so that at least 2 best cores can reach max boost clock in lightly threaded scenarios.

PS: 23°C sensors data added

Assuming your stock boost limit is 4.6, and you're +375, you should expect 4.975, though by no means is that guaranteed as that's silicon-dependent. Still, a 4.9-4.925 GHz overclock is nice! But I'm not sure why it's not coming through on the single-core CB23 score.

On to the MT, that's really odd.

CB23 MTAverage GHzCPU Core VID (Effective)TDCEDCPPTScore
amrnuke4.711.31967.5121.8113.312186
Jtaylor4.651.44471.7118.5123.712009

Really to me the biggest thing is how much voltage your cores are being fed (probably relating to my more aggressive CO). So even though your reported temp is only 75C, there are still limitations and I imagine that voltage is generating enough heat to promote throttling back to 4.65 GHz, despite that your cooler is better than mine.

Regarding my curve optimizer settings -- admittedly, I haven't run this through the grinder yet to look for WHEA errors... so mine may not be as stable as yours. Also, we might just have different silicon. My HWI result (right as CB23 was finishing - as you can see two of my cores have dropped to 99.2%!) attached.

Edit - what happens if you limit your PPT to 115W and TDC to 70 and EDC to 125 in BIOS?

IF2000 + DDR4-4000 C16 = max bandwidth ?
Should I not be near 90% of 64k with my AIDA score ?
( way over 60k - my numbers look like IF 1900 )
I think I found my " bottleneck "
But, where is it ?
BIOS ?

The performance of your L3 cache is abysmal. You're system isn't happy with the IF at 2000 obviously.

What I still can't comprehend is why core VIDs behave so differently. In yours and Jtaylor's and many other peep's screens they seemed more or less uniform, while in my case VID's fluctuates in quite a wide range.
I've never done proper stability testing - the system works just fine for everything I've been doing, except Paint3D, which crashes on saving, and crashes if I drag the window to my second monitor. So I got AIDA64 and ran the memory testing. You know how snappy my computer must be with a 5600X and 3733 14-15-14-30 memory and an SSD. Well, that also means that the BSOD with WHEA error popped up quite quickly. I mean, it was stunningly fast - fastest BSOD after an action I've ever seen! That's that Zen 3 IPC baby! MemTest errors all over too.

So if it makes you feel any better, it looks like I've got some work to do!

wow... some Paint3D related news, lol, thats surely strange and l'd suspect 2d-driver is the cause. You know, I've got vega56 before, and with 5700xt now, despite numerous complains of blackscreens and other s..t happen reports, I see display driver (2D) bugs is most annoying, and from peeps experience with 2-monitor setups its more obvious.
Btw, regarding snappy-thing, how do you see the responsiveness of UI might feel, if I move OS from 850 evo (sata mode) to my 2nd drive, that is nvme 970 evo plus? I mean is it worth the time wasted for transfering windows.

If you have PBO enabled it seems increasing EDC value can revert the L3 performance loss
PBO was Auto = On
I could not find any reference for PPT TDC or EDC for my config.

EDC = 160
( nothing else changed = all AUTO )

3Dmark 70 points under my BEST boost score at IF1900.
Nanos look Ok.
As you can see ,,, I recovered ALOT of L3 bandwidth

Still experimenting ... and reading your posts ..
.. thank you all

I did this and my scores dropped in cb23. I noticed all core dropped to 4570mhz to 4598mhz.

I’m not sure what else to do, guess it’s just the roll of the dice for silicone lottery. Seems my chips require a little too much volts. I also noticed they seemed a little higher than normal, but that just might be lack of testing from others.

most people I’ve seen with very high clocks or high negative CO haven’t done much testing. I think most people who have over -20 CO will have stability issues and whea errors. Passing cb23 or CPU-Z isn’t my idea of good standard for stability testing. That seems like such a huge offset if trying to run high cpu frequencies for ryzen.

good thing is it passed prime95 small fft+avx for 25hrs, so these OC results look stable. Will move on to occt and then wrap this up.

One last hurrah for bios 3003 before i update to a bios with AMD AM4 AGESA V2 PI 1.2.0.0 and support for Nvidia smart access memory.
Cold air benching with EK custom waterloop+TechN Zen3 waterblock :)
Curve optimizer = -30 allcore
Stable in everything i throw at it, and no WHEA errors.

If you still have this setup going, will you go to opendata.blender.org to grab blender benchmark and run it on v2.90 for all scenes on your 5950x?

@Jtaylor,
amrnuke


Looking at JTaylor's voltages in CBR23 MT run, at one point I even thought, maybe his CPU is the one downbinned from 2CCD chips? :)

Nevertheless,
@Jtaylor can you run CB23 mt with limits in PBO set to motherboard, instead of manual and post screenshot here, pls.

PS: Or may be his CPU is low SIDD one...

Here you go, this is my normal 24/7 settings from bios dump above.

No idea if this is good or bad, but i would think a static OC would be much better in a allcore render benchmark like this (?)
My cpu allcore average effective clocks were 4620mhz in pretty much all tests..

To sum it up: Like all other Ryzen before, Zen 3 likes it cool!
Unbelievable!

Now, if there was a theory explaining why one chip request a good 100mv higher than another in a same temp and power restraints for a cbr23mt-like workload, it would be a nice addition to such amazing, repeated from year to year (which is typical for reddit) discoveries that Zen like it cold.

You've got it pretty darn dialed in. Based on my experience all core overclocking I might think you could achieve slightly higher frequency or slightly lower voltage but that benchmark, particularly the Koro scene, is extremely sensitive on my 5950x.

4.6 all core takes around 1.28v actual. My temps are a bit better, but probably just due to a slightly lower voltage. Times are practically identical, down to the second on some of the scenes.

This was about the curve optimizer scaling..
There is a upto ~650mhz difference between stock (PBO) settings and CO @ -30 at the same temperature.
At -15 CO the difference is upto ~500mhz compared to stock

--> diminishing returns with curve optimizer.

Did you already know that ? I found it interesting at least.

Interesting. I am looking forward to getting my 5900X in from preorder. Though I mainly care about game performance, so I figure whatever gives me the best sustained boosts?

You guys are " kinda" funny ... blaming performance on heat ...
I got OLD news info for you ... it's ALWAYS been that way .

Shmee, you will want an ALL core OC for gaming.
There is no better performance with boost mode.
( try it in 3Dmark - don't be afraid )

My AllCore temp avg under 80c on P95 with 8+ hour at 1.35v
( 32c or lower at idle - depending on ambient )
You can pay more for more fans to cool liquids, and push pumps also...

I'm on air ... with a 4.6Ghz all core
( when I want to make a difference )

You will get more, with more GPU for gaming.
( my upgrade to a 5900x from, 3900xt was minimal at gaming )

However, the encoding in my background processes while I am gaming is not so noticed now .
( both are 12 core )

If you really want to " feel " a difference, get more cores !
( or more GPU )

Also, you might want to study your current game behaviors.
( total GPU memory utilized .. load ... etc why pay more for DDR6 not used !)
