August 9, 2023 - Got my 7800x3D to 19436 in cinebench by using curve optimizer negative offset. I think I've pushed it as far as it'll go. ... I found that I can access PBO settings two different ways, and when I try to make changes while accessing PBO settings one way, the changes aren't reflected when I save and exit (although they seem to be saved regardless??)

Anyway, you can try these changes. Change PBO (Precision Boost Overdie) to Enabled. Change Precision Boost Scaler to Manual, and set it at 10x.

March 29, 2025 - The moment you stick your head in the BIOS, you'll see that PBO is set to "Auto." I can't say that every motherboard will have PBO set this way, but every board I've encountered is configured like this. That won't do anything for you. This uses AMD's Precision Boost, not Precision Boost Overdrive.

BIOS older than the 1E3 and newer than the 1A have an issue with NVME slot 2 iirc Well you can probably set PBO to something between -20 to -30 all core and see if it is stable.

April 5, 2023 - We rely on the motherboard’s pre-programmed PBO parameters by enabling Precision Boost Overdrive. We find that the following values have changed: For previous Ryzen CPUs, increasing the platform boost parameters substantially impacted performance, especially for the higher core-count CPUs. For Ryzen 7000 X-series CPUs, however, AMD’s default platform parameters were relatively unconstraining. For the 7800X3D, it’s clear that the platform boost limiters are not the constraining factor.

r/overclocking on Reddit: Is PBO on a 7800x3D worth it?

December 9, 2025 -

New AMD user here. Upgraded from a 9900k to a 7800x3D. I have experience overclocking the Intel platforms from various generations. Very new to AMD stuff.

Heard PBO Curve editor could potentially squeeze out some extra performance by undervolting... but will I really notice a real world difference if I don't have problems with temps?

Don't really want to have a run in with messing with system stability for a 1-2% gain in overall performance/fps in games.

I use a Noctua NH-D15 and on Cinebench stress tests I hit max 70C on all cores at stock. No PBO set. Only thing set is EXPO for RAM

7800X3D is a very hot CPU by design (both VF curve and the fact how the 3D cache is stacked on top instead of below the substrate, such as in the 9800X3D). If you arent hitting 85C with cinebench, something is off. How are your scores? Now I see you understand PBO undervolts so you boost longer, always trying to reach max allowed temps. First try to reach that temp, then start the Curve Optimizer or Curve Shaper (better IMO) journey. Also, please keep in mind, it isnt overclocking per se, you’re just tweaking your cpu to run at the limit for longer. 9800X3D boosts all cores at 5.25Ghz whereas 7800X3D only does so for some cores and at a 5.05Ghz. Edit: check LLC.

I wouldn't worry about it, spending hours tuning PBO and CO gives you like 3% more FPS in CPU bound titles on a 7800X3D.. if you want to tinker then go for it but you'll be spending hours playing with CoreCycler and Cinebench instead of actual games..

r/AMDHelp on Reddit: Am I leaving performance off the table by disabling PBO with 7800x3D?

August 4, 2024 -

My goal is to keep my system completely stock, no overclocking and within AMD spec. Like my RAM speed for example I want to keep it at 5200mt/s as that is what AMD officially supports as the max for this chip.
.
But what I'm confused about is what exactly is considered "not an overclock" by AMD with the 7800x3D. Do I just keep the standard "Core Performance Boost" enabled and let the single core clock boost to 5Ghz as that is what is in the specs for the chip, or should I still look at enabling PBO? It's not clear to me if enabling PBO is actually considered an "overclock" and I've tried Googling this (and searching here) without a clear answer. Using Curve Optimizer does seem to be out of the question as I'm looking for a completely stable system and I don't like the idea of possible instabilities with undervolting (which is overclocking or maybe it isn't with this chip?).
.
Just looking for clarity on this. My understanding, which could be wrong, is that PBO is lifting some limits to increase the voltage to get a higher clock speed as long as the power and thermal overhead are available to it. On paper it does read like an "overclock", but considering the CPU at stock dynamically changes frequency under load I am not sure either. So if this isn't considered an "overclock" then I would enable it if there's room for performance gain but otherwise all I really care about is stability and not overclocking.

Is there a specific reason you don’t want to overclock? To answer your question: of course you’re leaving performance off the table. Enabling EXPO and doing a PBO CO offset are two of the easiest options to enable ever that result in good performance increases. Also, enabling PBO and setting a CO doesn’t necessarily raise voltages. In fact, like many AMD engineers have said “Undervolting is the new overclocking”. Most people utilize PBO algorithms to set CO offsets in the negative, reducing voltages across all cores on the CCD. For example, mine is stable at -23 all core. PBO sets an offset for given voltages across the curve, reducing how much each core draws to maintain certain clock speeds. Less voltage for the same performance reduces operating temperatures. Ryzen, for every 10C or so you take off of the temperature, the algorithm likes to boost 100Mhz or so in addition. For example, if you are hitting 85C with effective clock speeds of 4,750Mhz all core, that’s essentially the max you’ll get. While 89C is the max, X3D chips like to stay a few degrees below the max. However, if you were to change your cooling solution, say an AIO or liquid cooling, and all of a sudden your CPU is only hitting 75C when boosting to 4,750, it will then boost up to 4,850Mhz (which will also raise the temps up from 75C of course) So basically, by setting a negative offset, what you are doing is reducing the temps and increasing your performance. Where your CPU might have only boosted to 4,800Mhz all core, it may now boost to 4,850 or 4,900, or maybe even 4,950Mhz. Depends on your CPU, depends on the silicon and the cores and how strong of an offset you can set. While this is undervolting and not “overclocking” in the colloquial way we use the term, it is considered “””overclocking””” by AMD. However, despite what any warnings say, nobody would be able to tell you enabled it, and it will not void your warranty. Even if you ran PBO for years and your CPU died for whatever reason, you can still RMA it. They will not be able to tell you used PBO.

March 22, 2024 -

I just built a new pc the other day, it has a 7800x3d on gigabyte b650 elite ax. I was trying to set a negative pbo on it and basically I have some questions. So basically in the advanced settings of gigabyte bios there is a spot to turn on and configure pbo. In here you can set multiple different settings including what sets the temp limits, thermal trottle limit and curve. In here I have my curve set to a negative 20. However in the normal tweaker menu, there is a single pbo option that has a ton of choice. It goes by 70 - 80 - 90 celsius options with levels 1 to 5 for each temperature max. Do i need to enable this alongside pbo in my advanced settings or is this tweaker setting like a basic version? thanks

r/overclocking on Reddit: Looking for advice on PBO and curve optimiser for 7800X3D

April 17, 2024 -

First time PC builder here, and I was playing around with PBO and CO but I'm not exactly sure if I might have missed a setting or two in BIOS.

PBO was set to enhancement with thermal limit increased to 90C.

CO offset to -35

RAM set to EXPO II @ 6000mhz CL30.

I have encountered zero thermal throttling issues on both prime95 and cinebench. Temperatures averaging around 62C and 78C respectively.

CPU sits at 4.5 ghz for prime95 and stable 4.9 ghz on cinebench. With no stability issue encountered. Final score 17971 but I'm not sure if that's average or not.

Are there any settings that I have missed or should I attempt a lower CO offset since everything is going suspiciously well in my opinion.

Watch this video carefully and then read the comments: How to optimize Ryzen 7950X3D, 7900X3D, and 7800X3D (youtube.com) I went -40 with Extreme LLC (Aorus Elite AX Ice B650M) and put a 80C temp limit on my 7800x3d. Scored 18836. I've been playing cs2 for days now on these settings without a single crash or any stability issue that I can share. The comments under this video explain why it's ok to go -40 in combination with Extreme LLC. Long story short - the x3d chips are different than the rest of AMD (not to mention Intel) and are locked for max voltage at around 1.2v. The extreme LLC setting helps keep a stable voltage.
