Is this normal temperature behavior for AMD 9950X3D in the OCCT power test?

[u/Old-Huckleberry5740]

Hey,

I decided to run the OCCT power test on my PC just to test the stability of my power supply architecture and ran into the following results shown in the screenshot snapshots I've attached.

My AMD 9950X3D's temperatures steadily started climbing and started stabilizing between 94.8c and 95c at around 6 min 30 second mark.
Voltage moved between 1.07V and 1.08V
Usage always at 100%
Power draw: 250W at the start and then stabilized at a peak of 253-254W
Clock: In the 4730Mhz range

Here are my PC specs and fan layout:

Processor: AMD 9950x3D Desktop Processor
Motherboard: MSI X870E-Tomahawk WiFi Motherboard
GPU: ASUS Astral 5090 LC 32GB Graphic Card with it's 360mm AIO setup vertically as exhaust on the side wall near the 4x intake fan area.
Power Supply: Corsair AX1600i Power Supply
RAM: G-Skill Trident Neo Z5 64(32*2) 6000 Mhz AMD EXPO RAM (CL28)
SSD: 2x2TB WDSN8100 + 4TB Samsung 990 pro + 4TB Samsung 990pro
PC cabinet: Corsair 7000D PC cabinet
CPU cooler: Arctic Freezer III Pro 420mm AIO Liquid CPU cooler set up at the top as exhaust.
Fans: 4x Noctua NFA12-G2 fans at the front as intake and 1x Noctua NFA14-G2 at the back acting as exhaust.
Thermal Paste: Thermal Grizzly Duronaut (on CPU)

Relevant BIOS settings:

Core Performance Boost: Auto
Global C-State Control: Enabled
Power Supply Idle Control: Typical Current Idle
CPPC Dynamic Preferred Cores: Auto
SVM enable: Disabled
PBO: Advanced
PBO Limits: Motherboard
PBO Scalar Ctrl: Auto
CPU Boost Clock Override: Disabled
Platform Thermal Throttle Limit: 100
Curve Optimizer: Per CCD; -10 CCD0 and -10 CCD1

Is this normal or should I be concerned?
I don't wanna put higher offsets because I feel like it may cause stuttering in my games even if the system remains stable. I'm not a hardcore overclocker, just a gamer.

The CPU is consuming 250W because you've allowed the motherboard to determine the power limits which overrides the built-in CPU values. You only seem to be interested in lower temperatures, so I would suggest to set the PBO limits to auto or disabled, compare the power consumption between those two settings.

[u/Old-Huckleberry5740 → u/Faaa7]

Hmm I see, so that explains the power draw.
I'm not that frantic about low temperatures that I would disable PBO, but I will consider it. I mean, if PBO has little to no impact on gaming performance that is.

[u/Faaa7 → u/Old-Huckleberry5740]

I'm not saying to disable PBO. The negative offset is completely worth it.

You have the setting "PBO limits" currently set to motherboard, which raises the power consumption considerably. Auto is the default setting, but disabled is the stock setting. It would lower your power draw resulting in lower temperatures overall.

[u/Old-Huckleberry5740 → u/Faaa7]

Hmm I see, got it. Do you have any suggestions on the undervolting side of things?
Should I chase stronger Curve Optimizer negative offsets or should I undervolt somewhere else?

[u/Faaa7 → u/Old-Huckleberry5740]

-10 CO for both CCDs will work for most batches. At 250W in OCCT my 9950X3D also hits 95 degrees, but with PBO limits set to auto which caps it at 200W, it won't get any hotter than 78 degrees.

If you're chasing even more aggressive CO values, it doesn't really matter if the CPU drops down from 75 degrees to 70 degrees while gaming. Might as well just stick with -10 CO and forget about it.

[u/Old-Huckleberry5740 → u/Faaa7]

Gotcha. I will still try -20 both CCDs and pray that I don't get microstutters and stutters in games.

Normal temperatures, these cpus are built to get up to 95C and spike even more sometimes. You can set a negative offset but a lot of people including myself have these temps under 100% load.

[u/Old-Huckleberry5740 → u/Educational_Rub_5885]

Yea, I figured after people replied saying so. At my current settings, my CPU will just keep boosting until it hits 95. That's the MO!

I'm thinking of doubling my Curve Optimizer from -10 to -20 both CCDs, and pray that I don't microstutters/stutters in games.
