r/pcmasterrace on Reddit: Best settings for 7800x3d

March 13, 2024 -

I just recently did an upgrade from Intel to AMD and this is my first time using an AMD CPU. I read a few reviews and articles on the Ryzen 7 7800x3d. I’m decently tech savvy however I stay away from OC and messing around in the BIOS. Now I guess I want to change that lol

I only game so I figured I might as well try to get some more performance out of my rig while not going too crazy and making it unstable but since I’m not familiar with this, I don’t want to make any changes without knowing what I’m doing and why.

What would be the best BIOS changes or any changes elsewhere ?

My pc build: (started with a prebuilt and swapped parts in/out so that’s why some cheap parts are still in it)

in bios all u have to do is turn ram xmp or expo on

Heres what i did: Set PBO to "advanced" (auto or off by default) enable curve optimizer and set it to "all cores" start with -25 or -30mv and test if its stable. if not, try -20, if yes you could try and push to -35 or lower but you will probably lose performance. I got pretty bad silicon (stock: 16500 points cb23 at 4,75ghz) but i was still able to get it to 17100 and 4,9ghz while dropping temps and power consumption a bit (85°C -> 81°C and 89 -> 86w) Its pretty basic and you could probably get a bit more out of it but honestly thats way too much work for only little gain. Hope that helped!

7800x3D settings but you have an 9800x3D? my 7800x3D I run with -30 undervolt only, went right into it when I got mine and has been running like that for almost 2 years now, so I guess it's stable lol

2 of 3

7800X3D here. Just enable EXPO and make sure Resizable Bar is enabled. You can can undervolt but I don't bother.

r/ASUS on Reddit: Simple BIOS settings for 7800X3D ?

May 17, 2023 -

Hi, I just setup recently my new PC with :

Asus ProArt X670E Creator WiFi
G.Skill Flare X5 DDR5 6000 CL32 EXPO
Ryzen 7 7800X3D
Noctua NH-D15
Asus Geforce RTX 4070 Dual

Everything is already up and running just fine with the latest drivers. I just installed the long awaited non beta BIOS version 1415 for this Asus motherboard, so since the most critical problems are most likely gone, I thought it was about time to start doing a little bit of tweaking.

Currently I have most of the BIOS settings set as default except mainly memory set to EXPO 1. Anything else I should change ? Or is there any simple guide about that ?

I use this PC for gaming and work (mostly mostly Xilinx/AMD FPGAs so software such as Vivado, which can use all cores).

From what I saw in the articles about the 7000X3D CPUs, manual overclocking doesn't really seem worth the time and effort, so I would like to have only some simple recommendations on settings. I plan on using PBO with normal voltages, but I wouldn't mind getting some extra performance if it's simple and almost free in terms of effort, power consumption and stability. I'm not anymore into spending 5 hours tweaking for 0.5% performance boost with the risk of adding instability.

I heard the AI OC was setting voltages pretty high, which I don't want this time, I actually care about power consumption much more that I used to, although maybe not up to the point of undervolting.

Also I didn't install AI Suite nor Armoury Crate or MyAsus. I heard Ryzen Master could be good for tweaking oc in Windows, but I am totally fine doing that in BIOS only, since I don't plan on fine tuning that much.

1 of 1

By the way I am not a beginner about oc, I have been ocing my PC since 2000 and my first AMD CPU, a Duron 700. I'm also a hardware/electronics/computer engineer. But my last CPU was an Intel 4770K on an Asus Z87-Pro at 4.4GHz 1.24v (using this same D15 lately) so it's been 9 years plus my last AMD CPU was an Athlon XP iirc.... I did tweak my 4770K quite a bit but there weren't as many options.

r/overclocking on Reddit: 7800x3D BIOS Optimization

July 7, 2024 -

I saw this video of a guy optimizing the BIOS for a 7800x3D on a X670E Taichi:
TheWhale - https://www.youtube.com/watch?v=K-NsWD8F54o
Sadly he doesn't elaborate on all changes he did, so I noted down the full list in hopes others have input.
I use my PC solely for browsing and gaming. Only devices hooked up is keyboard, mouse and a Xbox controller.
7800x3D, NH-D15, B650 Taichi Lite, 2x16Gb, 6900XT, 750W SuperNova P2, Win10.

His BIOS suggestions:

OC Tweaker:

Performance Preset: PBO, Tjmax = 85C and Curve Optimizer -20mV
DRAM Profile Setting: Auto > XMP

DRAM Performance Mode: Auto > Aggressive

Infinity Fabric Frequency: 2000-2100

OC Tweaker\External Voltage Settings:

The whale is one of the most idiotic spastics on the internet, he's a sperg, he doesn't know what he's talking about and half of the tweaks he lists in his video are placebo and he doesn't even know what they do. He blocks people on Twitter who don't agree /w him, for instance, I once called him out for buying the most expensive motherboard (or one of) for his friends 7800X3D build which was the X670E Taichi Carerra and his response was "it's the best of the best" when you do NOT need to go that deep (pockets wise) for AM5. Please ignore this video and do better research.

r/AMDHelp on Reddit: can someone demystify some of the 'suggested' 7800X3D Bios settings for me please?

January 2, 2024 -

Hello,

I am using the holidays to spec and build a new system, yay! Coming from a 9700K I think I have understood the BIOS settings my old ASUS z390 board could offer. Now, that I have a 7800X3D in my new SFF build, I am benching and tuning it to my hearts content. I am a happy tinkerer :)

What I am less happy about is the level of documentation of BIOS settings, both within the BIOS and on paper. I own a ASUS B650E-I board now and found it working quite well for my needs (except for my desired LLC settings, but that is another topic...). Sadly, the Mainboard manual does not explain BIOS settings much so I am at a loss on what settings exactly do. If you have resources that listing and explaining them in more detail, please kindly send a link. (NOTE: I could find a few while researching, but happy to receive opinions on some settings as well)

I could find some 'suggested' values from a YT video (well, it is for B650E-F, but close enough), but it does not go into depth as to what these settings are actually doing, wanting to understand why I would change them.

CPU Configuration

~~PSS Support: Default:~~ Enabled / Suggested: Disabled - What is this setting doing?
~~NX Mode: Default:~~ Enabled / Suggested: Enabled - OK, don't know exactly what it is doing, but leaving it on.
~~SVM Mode: Default:~~ Enabled / Suggested: Disabled - OK, this is CPU virtualisation, not needed

AMD CBS

~~Global C-State Control:~~ Default: Enabled / Suggested: Disabled - Found video explaining this using suggested setting - Keeping enabled
~~IOMMU~~: Default: Enabled / Suggested: Disabled - Why would I disable this!? - keeping enabled

CPU Common Options

Power Supply Idle Control: Default: Auto / Suggested: Typical Current Idle - Found a post here, but why that value? PSU is a Cooler Master V850, does it matter?

SMU Common Options

~~CPPC Dynamic Preferred Cores:~~ Default: Auto / Suggested: Cache (7800X3D) - I get why the 7800x3d would be set to cache and 7950 to frequency (# of CCDs and task prioritisation), so just for verification, setting to cache good or not? - Leaving on Auto

AMD Overclocking

SoC/Uncore OC Mode: Default: Auto / Suggested: Enabled (sets Infinity fabric to run on max speed all the time) - why? performance VS idle-power? What are the draw-backs to this?

Thank you kindly for any response to the above!

EDIT: Ticking off answered points

You really should not be changing settings you have no idea about unless you're having a specific issue you're trying to resolve. It is best to leave them on default Enable/Auto values. PSS Support - Enable/disable the generation of ACPI _PPC, _PSS, and _PCT objects Processor performance control is implemented through three optional objects whose presence indicates to OSPM that the platform and CPU are capable of supporting multiple performance states. The platform must supply all three objects if processor performance control is implemented. The platform must expose processor performance control objects for either all or none of its processors. The processor performance control objects define the supported processor performance states, allow the processor to be placed in a specific performance state, and report the number of performance states currently available on the system. -- enable it NX Mode - Enable/disable No-execute page protection Function -- enable it Global C-State Control -- keep it enabled unless you're having issues with windows going to sleep/suspend and not resuming back to normal. IOMMU - leave it on Auto CPPC Dynamic Preferred Cores - for 7800x3d it does not matter as all cores have access to full cache, leave on Auto

I am using Ryzen 7 7800X3D. Are there any settings I should configure in the BIOS?

1 of 1

Depends on the motherboard, but normally the only thing you need is to make sure XMP/EXPO is enabled for your RAM. If you had any custom bios settings prior to the 7800X3D chip install, I would also make sure to clear the CMOS to clear out any old settings and revert to defaults, then enable XMP/EXPO for your RAM.

February 27, 2026 -

Yesterday i Upgraded to the 7800x3D. Im on a X670E PG Lightning board.

For now i have in OC tweaker:

Game Mode: enabled (this changed some things automatically i think like voltage to 1.200)

Pbo: enabled

Expo Profile 1 activated to get my RAM to 6000mhz and 30cl

Unser Advanced tab

Pbo settings: Auto (Not enabled)

Resizable Bar: enabled

Is this it or am i Missing Something? I'll also be doing Thermal throttling and voltage throttling Tests in hwinfo64.

Cheers in Advance!

You don't need game mode, it id for double CCD CPU. You can play with nitro and timings, check those screens https://www.reddit.com/r/ASRock/comments/1r9q0vu/410_results_with_gdm_and_without_it/ You can play with PBO and CO, -20 should be fine

Game mode disables SMT on single core CPUs. Disables the non X3D CCD on dual CCD X3D chips .. I'm not sure what it does on dual CCD non X3D CPUs though Very few, if any, games benefit from it being enabled with single CCD CPUs With my daughters 7800X3D/B650E PG Riptide WiFi setup I run fairly conservative settings Performance Preset of 85c TJMaxx CO -20 all cores. PBO limits motherboard. Load Line Calibration 2 for SOC auto for CPU. MCR PDM GDM all left enabled. iGPU disabled. AGESA default. vSOC 1.2v. SCALAR auto.

r/PCBaumeister on Reddit: Optimal BIOS settings for 7800X3D and Undervolting

April 5, 2025 -

Hey community!

I'm looking for the optimal BIOS settings for my system to get the best performance out of my CPU (7800X3D). I also want to use undervolting to optimize temperatures and performance.

My system:

CPU: AMD Ryzen 7 7800X3D
GPU: ASUS TUF RTX 5080 OC
Motherboard: ASUS TUF X670E WIFI Plus BIOS Ver. 3222
RAM: 32GB G.Skill Z5 CL30 6000MHz
PSU: Be quiet! Power Zone 2 1000W Platinum
Case: NEXT H6 Flow
CPU Cooler: Be quiet! Dark Rock Pro 4

I've already tested some settings and run benchmarks using half-baked knowledge and crappy YouTube videos, but I'm not sure if I've found the optimal settings. So I'm asking you guys:

What BIOS settings are recommended for optimal performance of the 7800X3D?
How can I optimize undervolting for the 7800X3D?
Are there any specific settings I should definitely enable/disable on my motherboard?

I can barely find anyone who has my motherboard and is simultaneously sharing undervolting and optimal settings for the motherboard/CPU.

I'd really appreciate your experience and tips and can gladly share more information if you have questions or if I haven't provided enough details.

PS: I did a clean install of Windows 11, installed all updates including the latest BIOS, and completely reset it so I can start over with your help.

Thanks in advance!
