Question Is this sweet spot for Ryzen 5700X

[Mir96TA]

I was trying to play with Ryzen 5700X PBO setting
I would like to know, Am I at sweet spot ?
PPT=130 TDC=82 EDC=138
Curve Optimizer is Negative 30



I am using CINEBench R23



Thanks in advance

I can't say for sure, but that is a nice memory OC you seem to have going there. What memory are you using and what VDIMM are you applying?

As for the PBO tuning with the curve optimizer, a -30 offset seems very optimistic. I believe I am running -9 all core on my 5950X, though I believe my scalar is 2X. What are you using to test for stability? (Hint: you can use the p95 with corecycler, to test each core boosting for stability)

 

[Mir96TA]

I didn't realize I was really O.C. the memory.
I thought I was running at stock.
This Ryzen can go upto 3600 Memory Frequency but memory I have it is good for 3200 only
Dram Voltage (VDIMM) is coming from XMP profile, I think Asus call them DOCP!

 

[Mir96TA]

I have not used to validate the stability.
I often use enterprise Machine, for example Windows's Server, Firewall management software. That cause heavy memory usage 90 to 95 % of the memory (26 GB to 30 GB).
I can not Offord instability.
My workload is my validation

 

[Mir96TA]

Here is my fine-tuned one.
PPT=140W TDC=90A EDC=150A
All Core have - 30
Scaler is 10 X
200 Mhz
All Core are as a cure optimizer Negative 30
Here is a Cine



I didn't O.C. I need 100 % stable and able to runs weeks non-Stop.
I am not sure, if I can further optimize ?
Any input is greatly appericated

You realize that tweaking with pbo2 can cause instability? It is basically a form of OC, especially with the +200 MHz. That is why you need to stress test

No I didn't know.
I thought me running memory nearly to full gives enough sress
I guess I can P90 ?

 

[Shmee]

Yeah, you can run P95, or try core cycler, that can test individual cores and tell you which core fails, if any.

I ran it, when I came back System reboot it, with UEFI screen CPU error, Temperature.
haaa aaaa
I guess I need better cooling

 

[Shmee]

More likely your tweaks aren't stable. The CPU should throttle as it gets too hot, but you are basically undervolting to the max, so I am not surprised it crashed. I suppose if your temps are high though, that doesn't help either. What cooler do you have? And when checking the event viewer, are there any WHEA errors?

 

[Mir96TA]

Well I have set Limit on UEFI 90C which is also TjMAX for my CPU.
So MB rebooted and stop at UEFI screen witch CPU Temp error.
Cooler I have is Corsair H55 Quiet
I am going to check WHEA errors.

 

[Mir96TA]

Only error I saw was Kernal-Power 41

You could try setting a temperature limit a bit lower, like 85C or 82C or something. This should help keep the core temps from getting out of control during stress testing, gaming and any rendering work.

Curve optimizer at -30 isn't stable all core, some cores won't be stable at less than -10 normally, you'll do much better with going down to 100-150mhz with your pbo, you should test each core singularly when you change the curve optimizer by -5, so that you can work out exactly what the problem is. A kernal 41 failure in this case will be a core failure, if you go into "event viewer" and look up whea errors, it will tell you which core crashed, that's the most important thing for you to sort out first, your ppt, tdc and edc should come after that, chips can be very different, I'm not that great at it, but it's a bit of an art. Anyway you should be able to get your CPU at 4.8ghz all core if you spend the time, it's really frustrating but satisfying in the end 😄

Curve Optimizer with all core at -30 is quite a stretch. I didn't feel like messing around with it much, so I set all core -10. Other than that I did +50 MHz, which brings it to 4.7GHz max. I kept power modest. PPT 95W, TDC 90A, and EDC 140A. I limited temperature to 90C. I just put it in a week or two ago so I am sure I will keep playing with it when I get some time.

I think your power settings are good but I would cut back on CO to either per core if you have the time or try -20 and go from there.

By changing anything you risk stability. You don't "optimize" without risking stability. Especially with +200MHz and a scalar of 10x !! If you want stable you leave scalar alone.

I got my 5700x crapping on the 5800x, passed core cycler too.
