How is the CPU stability with such aggressive negative curve? I heard it can be unstable at low loads.

It can take time for that instability to show up, when mine was right on the edge of stability i'd get maybe one game crash a week before i tuned it in fully

Nothing stability when undervolting. 4 months now I never had any crash. Have 14 titles on my main pc like WarZone 2.0, Arma 3, DayZ, Fifa 23, DCS World, NBA 2K23, F1 22, Automobilista 2, WRC Generations, ELDEN RING, Dead Stranding, The Forest and 2 more. I play 4-5 hours per day. My Pc still open 12h/24h. Im works Photoshop and some music programs like Fruit Loops. Im ok atm with better performance and excellent temps.
With the 5600x I used Core Cycler. I'm bored now....Really I hate wasting time on something like that.
These values give the Ryzen Master after Curve Optimization by Per Core with custom settings by BIOS as:
PPT: 120W - TDC: 75A - EDC: 130A
FITSCALAR: X1 (or Auto) *with X1 is better for me.
FMAX ENCH: OFF

My board its one of the best B550 such as MSI B550 Unify, Gigabyte B550 Aorus Master......with 14+2 phases - Dual Output, VRM type DrMOS - excellent Mofset and one of the best PWM Controller.
Also the ARCTIC AIO for me is the "best AIO" ever at all. I tryed before 3 ΑIO's mores on my old 5600X: Raijintek EOS, Orcus, Thermaltake, Coolemaster. The Liquid Freezer II 360 is top on another level of performance and quiet peaks.
I can oc more +75mhz without problem with different high negative curve but I don't need it - the differences are non-existent in the gaming and i don't care to be a slave to the Cinebench scores.
It can take time for that instability to show up, when mine was right on the edge of stability i'd get maybe one game crash a week before i tuned it in fully
Yes dude, need time

Instability varies a lot depending on how you set it up
If you do the +200 for low threaded boost, you'll find it a lot harder to undervolt - my 5800x only did -5 with +200, and -15 with 0

These days we have a lot more automated tools to find problems much faster

Curious as to how zen3 fares with AVX2 stability. Particularly 1 threaded load. I'm currently building and testing a new zen4 computer, and have been plagued by random reboots at idle. Very hard to replicate, but one test I've seen that fails even at "stock" (BIOS defaults for Asus motherboards tends to be a little out of spec), is the Prime95 1 Core Smallest FFT AVX2 test (with hyperthreading turned off for single thread boosting and max clocks). I have managed to make it run stable, by lowering Vcore 0.015V and adding +5 Curve Optimizer for two problematic cores, one being Core 0 which probably is bad, and might reveal the issue I'm having, but also might not be related at all. I started this testing using P95 30.8 manually assigning affinity using Process Lasso (testing 1 thread for each core), but using Core Cycler is easier. I've attached two CoreCycler config.ini files, that should automate this (testing all cores). The torture one (rename it to config.ini before using) also includes the suspendPeriodically = 1 setting which makes it even harder stability wise, if anyone is up for giving it a try :)

idle reboots on zen3 are entirely related to SoC issues, too low an SoC voltage or too high infinity fabric

Everything would be stable at load and stress tests but crash at low loads - when the CPU was boosting individual cores to higher clocks vs the lower all core loads a stress test provides

Interesting, I'm going to test if this might apply in my case. It's my first Ryzen build, so I missed a lot of the "history" of previous gens.

Whats the full hardware setup of the PC?

Everyone, and i mean everyone forgets that Zen3 only supports 3200MT/s with two single rank sticks out of the box, and then tries to get 4 or 8 ranks running at 3600 off XMP and scratches their heads why it has issues

1672374950528.png



99% of the time raising SoC voltage to 1.10v or 1.15v resolves the common ryzen issues of low-load crashes and USB disconnects, because the SoC inside the CPU is memory, PCI-E and USB in one - errors or problems on one part, causes the others to risk resets or freezes (Hence PCI-E risers causing errors making USB ports reset and drop in/out)

Full specs are:

ROG STRIX B650E-E GAMING WIFI
Ryzen 9 7950X cooled with a Cooler Master 240 AIO
Kingston Fury Renegade DDR5 6400MHz 32GB (KF564C32RSK2-32), RAM speed doesn't matter for my problems, equally unstable at 4800 as 6200, and all RAM stability tests shows 0 errors
Gainward Phantom 4090
Western Digital Black SN850X 2TB (WDS200T2X0E)

I tested all the BIOS files available for this board, and played with the Infinity Fabric speed (tried 1600, 1800 and default 2000), and interestingly, with all voltages on Auto, Vsoc doesn't budge from 1.040V (BIOS thinks 1.040Vsoc is fine for 1600, 1800 and 2000IF). However, messing with RAM speed, Vsoc went all the way up to 1.335V for 6200 (4800 is BIOS default-> Vsoc=1.040V). So the BIOS ups the SOC voltage depending on RAM speed, and not IF. I tried to increase Vsoc manually (up to +0.25), but stability didn't improve.

I posted in another thread here, that maybe I have encountered some sort of PBO/Curve Optimizer bug, that somehow survives clear BIOS/BIOS flashing/loading optimized defaults. But the more I think about it, I wonder if I'm being pranked by Ryzen Master. At some point early on when I got this system running, being new to Ryzen, I had to try Ryzen Master. And, of course, I also tried the Curve Optimizer "auto" optimizing feature. But after the initial "Reboot Required" prompt from Ryzen Master, the system refused to post. Which felt really odd at the time, and I tried powering the PSU off, let all power drain and start again, still nothing, and I had to Clear CMOS and load my good BIOS profile to get it back up. So somehow Ryzen Master made my BIOS settings unpostable. I didn't think of it at the time, but I wonder if this is where my problems started. Random reboots while gaming, hard to tell when it started, and soon also while just browsing the web. Most stability testers showed no problems however, until I tried P95 AVX2, which also made my system reboot.

So, how does Ryzen Master work? Does it mess with BIOS settings? Maybe there's some broken driver or service loaded in windows that still is trying to Curve Optimize my system...lol, I don't know, but I'm still on the same windows install.

Be aware that's an entry level cooler and a poor one at that, it's not going to do well on a 7950x

People always forget that the memory controller is not RAM
Just because your RAM passes a RAM stability test doesn't mean that your memory controller can't have stability problems, since it's tied to other hardware as part of the SoC


6400 is too high for zen3, I'm not aware of many kits running on expo/XMP above 6000 without needing tweaking
No, auto doesnt think it's fine for X Y and Z IF - auto just has a few presets that are nothing more than guesses since DDR5 is in it's infancy, and it cant compensate for more memory modules or ranks


ryzen master literally changes your BIOS settings. That's what it does, and what it tells you it's doing before it restarts to apply them.

Yes, that makes sense. Full story is that I installed Ryzen Master, tried the Curve Optimizer once, which stopped my system from posting. After that I only used it to verify my settings in Windows (which is useful), and everything looked normal, all the PBO and CO stuff I applied in BIOS was reported as expected in Ryzen Master. I never used it to tweak my system after the first fail which didn't instill much trust (lol). But over the last few weeks I have tested many PBO and CO settings (via BIOS), and would expect anything once done by Curve Optimizer to be overwritten? I did flash my BIOS many times, Clear CMOS load Defaults. I'm thinking Ryzen Master was loading something in Windows that whacks up PBO/CO so my system became seriously flaky. And have done so completely hidden from view, not reported anywhere...

Anyway, Ryzen Master is gone now. And I will go back tomorrow and see if I can touch anything PBO/CO related again without my system going haywire.

Yeah but if you loaded ryzen master again, it could have altered those settings again - even ones you're not aware of
Reset to optimised defaults and try fresh

Can't say how AM5 has changed the layouts exactly, but in all recent Asus AM4 BIOSes there are multiple locations for both PBO and Curve Optimizer (except 5800X3D).

The most accessible PBO menu for most people is found under Tweaker tab, but when Ryzen Master changes your settings it instead edits the PBO menu found under AMD Overclocking.

If you're testing Curve Optimizer, use your choice of something proper like corecycler, OCCT, or ycruncher with custom affinity. The "testing" tool for CO in Ryzen Master is not even on the radar in terms of effective testing

On my 5800x3d i dont even have PBO... i cant change ANYthing on ryzen master. Or in the bios. Its on a gigabyte x570 aorus elite wifi.

I dunno if gigabyte disabled it or what is going on.. but i cant even overclock my 5800x3d if i wanted too. First time in 23 years ive been locked outa overclocking. Its funny. Only thing i can do is flck and memory timings and overclock.

I mesn its fine.. i guess.. cpu does what i need it too lol.. but dang. At least with athlon xps i could use a pencil to unlock it !!! LOL

PBO settings for 5800x3d are dependent on the mobo vendor. Officially there's no tuning available for it. Either you get it with a BIOS update or you have to use modded BIOS. Alternative is PBO tuner in Windows with autoload on startup.

Realtime as Process Priority and Windows 11. Could i even run 4.75 Ghz with 1.25V on this 24/7? Anyone know that?

6400 is too high for zen3
Assume you meant "Zen 4"?

This is not 100% true.

Even if you lock your CPU to an all core load running any PBO limt (EDC TDC PPT) will still work and CO will still work in the sense that it will still reduce voltage to the core but not increase its clock speed.

New version of PBO2 tuner has a builtin monitor function and I can confirm that locking all core and running -CO does indeed reduce voltage per core on my 5800X. So you don't get the boost in clock
speed because your clocks (multiplier) are locked, but you do get the reduced voltage and power.

Using a negative CO can help you pass R23 for example with a locked all cores like 4700. I need to use a specific CO of -30 -30 -5 -30 -30 -30 -30 -30 to pass R23 with 4700 all cores.

If you set them in the BIOS, they definitely do nothing


VID is a requested voltage, and doesnt mean jack for the actual voltage
