In almost every overclocking video I see for this cpu they using x10 pbo scaler isn't that a fast way to kill the cpu? , also I heard amd recommended to do this?

Fully admitting I don’t know a whole lot about overclocking.

I see a lot of conflicting info about the scalar setting for this CPU. I enabled an automatic overclock with my MSI board and set CO manually. So it’s:

• PBO set to Advanced

• Precision Boost Overdrive Scalar set to 10X (this was the default value after setting PBO to Advanced)

• CO is set to -20

• Cinebench r23 scores: 23503 multi and 2083 single

Everything has been really stable. Max temp of ~80c when running Cinebench multicore. ~72c max when gaming. ~45 idle.

My core speed stays at around 5.2. My max voltage from what I can see is 1.155 V with an average of 1.064 V.

Should I turn Scaler to 1X to extend the longevity of my CPU? What difference will I notice with it at 1X vs 10X. Does it just keep my base boost at 5.2 for longer?

Sorry for the noob questions - just want to make sure I’m not ruining my cpu or degrading it faster over time.

Hi there, i don't know much about overclocking, i changed the PBO settings of my 9800X3D to the following:

PPT: 120000

TDC: 80000

EDC: 110000

Max CPU Boost Clock Override: +200mhz

Curse optimiser: All Cores, Negative, -30

My PC Setup is:

Windows 11 home 24H2

Gigabyte B650 EAGLE AX

32gb (2x16) Corsair vengeance ram at 6400mhz, CL36

ZOTAC RTX 4080 Super Trinity OC 16gb (undervolted, 2580mhz at 925mv)

Ryzen 9800X3D

Be Quiet Dark Rock 4 Pro air cooler

I'm not up to date with cinebench tests of temps during them, so if any of you could let me know if these results are good, thanks!

Multi core score: 22693 Single core score: 2179 MP ratio: 10.41 x

Should i attempt this again with limits set to motherboard and a 10x scalar?

Hello everyone,

I've been reading mixed opinions about scalar settings in various places. Some claim it's completely unsafe regardless of temperature or voltage, while others openly recommend using a scalar value of 10x. This left me wondering: are there any official documents or reliable sources that clarify how safe or unsafe this setting actually is, what it does, and what to look out for to determine if its current state is safe or not? If anyone has experience with testing, I’d really appreciate your input.

From what I understand, the scalar increases the Vcore curve and extends the boost duration. But if Vcore spikes stay below 1.3V and temperatures remain below 80% of tjmax, how exactly is this unsafe? According to HWiNFO, current limits aren't even being approached. The only potential concern I can think of is the extended boost duration. But isn’t that what the limits are for?

In some demanding stress tests, like Core Cycler, I’ve noticed that both the effective and target clock speeds drop by about 50–100 MHz after a while. Depending on the test, clock speeds range from 5.2 to 5.4 GHz, with the most demanding workloads typically at 5.2 to 5.3 GHz. Could scalar influence this? For example, could it allow higher clock speeds even under the most heavy loads? But then again, I wonder how this can be unsafe when there are limits in place?

Also, how relevant is any of this for someone who mainly plays games? Based on my in-game temps and Vcore readings, gaming scenarios don’t seem to resemble these stress tests at all. The only time I saw behavior that came close was during shader compilation or loading screens. Helldivers 2, spiked to 1.33V and hit 82°C for just a second when launching for the first time but then never again. This was with the scalar set to 10x. I am also pretty sure I could recreate this with the shader loading when you launch CoD, but I can't test that at the moment.

I tested scalar settings at 1x, 5x, 6x, 7x, and 10x for stability and benchmarks. Performance differences were minimal, under 5% across all scores. Vcore varied by about 0.02V, and temperatures differed by maybe 1–3°C. So for now, I’ve left it at 1x. Still, I can’t shake the feeling that I might be missing out on some performance, and in general I’m just curious.

Apologies if these questions sound basic. I've really tried to understand this topic based on what I found online.

In case anyone asks, here are my current settings and specs:
Ryzen 7 9800X3D
Rog Strix B850-f
Arctic Liquid Freezer III Pro 360
2x16 GB G.Skill Trident Z5 Neo 6000Mhz CL30
Asus Prime Rtx 5070 Ti
1000w Corsair PSU
Fractal North XL

EXPO I enabled
PBO enabled
Curve optimizer: -20
+200 MHz boost override
Scalar: 10x (now at 1x)
Motherboard limits enabled

My Cinebench R23/R24 scores are in line with other similar OCs. Stability tests like OCCT and AIDA64 ran for 30–60 minutes with no issues. I’ve been gaming for the past three weeks without any crashes or instability, so I’d say it's stable.
Effective and target clock speeds range from 5.2 to 5.4 GHz depending on the task. Under full load, effective clocks are usually within 20-30 MHz of the target. In stress tests and some loading screens, Vcore very rarely spikes to 1.30V, but it averages around 1.22V. During gaming, it ranges between 1.0 and 1.2V. Temperatures in stress tests always stay below 85°C. To me, this seems stable, and I haven’t observed any signs of clock stretching. But if I’ve overlooked something, I’d appreciate any corrections or advice.

Hi all

Can anyone share some recommended PBO limits please for the 9800XD?

It’s a friends build, I have the 5800X3D and run -30 all cores and 100/65/90.

I’m assuming 9800X3D uses different figures?

Thanks

The guy is talking how 1.2.0.3a and 1.2.7.0+ are the only best AGESA versions for performance.

Is this even true?
