5800X Boost set to 5050Mhz all cores with AMD Curve Optimizer

Thanks for the tips.

I changed the PSU idle control to Typical = still crash
Then I disabled C states = still crash

This is the current PBO settings (curve optimizer/advanced PBO settings are disabled)

What else can I try?

Update, I reset all the PBO settings and copied all the settings I found in this video, except for curve optimizer - as soon as I enable curve optimizer the PC crashes at the windows login screen.

The system is now stable :)

So I can build from this. Only issue with the settings in this performance loss. The PBO settings image above gives 11000 cinebench r20 multi and 630 single. The settings from this video gives 10700 multi and 610 single.
Any ideas which settings can be tweaked a bit to get performance up?

Funny thing though with these settings, they seem to produce higher clocks yet performance is lower. For example single core shows up to 5240mhz yet score dropped from 630 to 610.

I thnk fmax enhancer might be causing that, should I disable it or does something else need tweaking

Keep FMax off, that increases clock frequency but lowers overall performance from what i have seen on Ryzen 5000. It worked a little better on the 3000 series.

Try this settings.

PBO Enabled
PBO Limits Motherboard
Scalar x10
Auto OC 50Mhz (you can perhaps try increasing this later to 100Mhz)
Curve Optimizer (use Ryzen Master to check your best cores on CCD0)
Set best cores (two cores) to -5 and test using Cinebench R20 ST bench.
Use Task Manager to set affinity to one of the two cores after you start the bench.
Use HWINFO to observe effective clock speed for the core you are testing.
If you pass stability for both cores, repeat steps and use -10 in Curve Optimizer for them. Rinse and repeat.
You should manage somewhere between -10 and -25 for your best cores.
If you get instability, dial back -5 in Curve Optimizer.
Rinse and repeat for each core.
The higher you have Auto OC, the less negative voltage you can apply in Curve Optimizer. Actually, it's better to tune Curve Optimizer more than increase Auto OC from my testing, but we still want a little Auto OC 50-100Mhz tops.
It takes time, but if you want to maximise performance and boost frequency, this is how you do it.


I use the exact PBO settings mentioned above and this is what i see in HWINFO64.

I gave PBO another quick try with these settings

2 best cores (0 and 6 for me) on -20 curve. All others left on positive 0
PBO limits motherboard
Scaler x10
Auto OC offset +100Mhz (I tried 50Mhz first which worked)

Single core boost has gone from 4850Mhz to 4950Mhz (as expected) when running R20.

Why should your HWINFO64 show 5100Mhz? This presumes that a 250Mhz offset has been used, or am I missing something

His is 5950X, which starts at 5050MHz + AutoOC 50MHz
Yours is 5800X which starts at 4850 + 100

On a separate topic, you may be interested in HWiNFO tickbox in settings: Snapshot CPU polling. I find it shows more realistic frequency and voltages per core.

This.

Snapshot should show similar to Ryzen Master i believe.

You could try and aim for 100Mhz, so you will get peaks of 5Ghz. Seems a nice round number to me, however this will affect stability so you'll need to lower the negative voltage in Curve Optimizer.

In MT workloads like Cinebench, 3DMark and even games that use lots of threads (like COD Modern Warfare and other online games) you will see more benefit from a lower Auto OC setting and more aggressive negative voltages.

I will put up a video of what I see for all core boost in COD at the settings above later today. :)

Are right, makes sense, thanks :) I thought Matt was showing the 16 threads, not 16 cores above.

I don't see snapshot CPU polling in HWINFO64 under settings > general. Is it in another area?

I have 100Mhz set already, to boost to 4950Mhz, do you mean 150Mhz?
Setting manual all core OC, all cores were stable at 4.7Ghz at 1.2625V

Why does applying negative voltage to multiple other cores benefit multi thread use? Thanks for video, it will be interesting to see all core boost in COD with negative voltages applied

Using CO cores receive less voltage at any given frequency, consume less power and emit less heat. Thus they can boost higher in multicore tasks before hitting power and temperature limits. Thus more performance.

My bad i thought you were using a 5900x. :o

Video is uploading now but we're looking at all core at around 4.925Ghz in game and this game puts a load on 16 cores with regular spikes of a few cores up to 5.1Ghz.

The negative voltage extracts more performance per core by allowing a higher frequency per core, which really helps MT workloads.

5800X, no probs :)
Now I have identified my two best cores, should the others be left as is in order to maintain stability? I guess applying a small negative voltage may resilt in a high frequency, but also more instability

The following was afte a couple of games of COD. Best cores highlighted

I think its already been mentioned in here but believe PBO2 allows for combining best core boost with an all core boost e.g. 4.7Ghz 1.2625V all core, PBO +100Mhz -20 curve on 2 best cores.

Hopefully that's how it works anway

Was that with +100Mhz on Auto OC?

The higher negative voltage values you use, on the best cores and your other cores, the higher MT frequencies you see so it really depends what you want.

Do you want higher single thread (1-4 cores) performance or higher multi thread (4-8 cores) performance?

If your answer is the former, you'll want to put Auto OC up to 150-200Mhz and tune your best two cores, then tune the other two best cores. You won't have as much headroom for negative values, but you want to add as much as you can to your 4 best cores to encourage higher frequency.

If your answer is the latter, you'll want Auto OC at 50-100Mhz (tops) and tune your best two cores, then all the others adding as much negative voltage as you can without instability at load or idle.

If you only use 50Mhz-100Mhz, you should be able to get negative values (10-20 perhaps more) on all cores.

I find that you can often add more negative offset to the other cores as they don't boost quite so high, i would imagine this should be the same for all CPUs. My lowest offset cores are my two best cores as they boost so high, they cause instability if i use a too aggressive negative voltage.

Correct, +100Mhz on offset in BIOS (if this is what you mean by Auto OC)

Ideally I would like single core boost to 5Ghz on best cores and all core 4.7Ghz which I know is stable at 1.2625V
Given your options, the latter - higher multi thread

Good vid, but SA87 as your primary weapon, yuck! :p

Yeah it's my number 1 used weapon because it's British lol. I know it's really bad in this game though so I don't make my life any easier by using it.

I have it tuned to try and make it better though, mainly focusing on the terribly slow aim down sight speed. It's good for longer range engagements but sucks up close.

It's British...I might use it too now :D

I would compare fps but hate you cant select specific maps. Picadilly is the one that cripples fps for some reason for me. Around the busses its runs like spuds

Yeah it's a shame they won't let you pick maps, if they did that I'd be on Shipment 24.7 Lol. Absolute mayhem!

Piccadilly is demanding, i noticed my FPS dropped into the high 150's around those buses, not sure why. It does look nice graphically though.

I find the Oil Rig map (Petrov?) can be demanding too.

I find that all my cores will boost to the same speed regardless of how much offset is used the only thing that changes that is adding +100 etc then that will all boost 100 MHz higher so maybe it's just the early bios.

Sure i read it was just poor optimisation if a couple if objects. I think picadilly is the burning car near the busses. I remember i stood on top of it and looked straight in and got about 30fps (2080ti, 4790k) when usually i was getting 80 or 90fps on all maps

Yes that is different from what I see. If i remove all the negative voltage my all core frequency goes down to 4.6-4.7Ghz. That said, i suspect it's a combination of both, but for me the negative voltage provided more benefit.

Interesting. When you say car, is it more like a land rover? If so i think i know where it is. I will have to try and remember to try that out next time.

If you can ever grab a screenshot of the spot and the place where you aim, let me know.
