Thanks to NV UV play that has a community tested profile list that I was able to find a setting that someone tested and posted as stable and had 4.8 stars from others so I tested it and all the games that would typically crash after a while aren't crashing and this is now very stable for everyday use.

For some reason all my 3D mark score now show up as unknown but the results are fantastic. On heavy load in games the highest the power draw gets to is 500W which is still better than pulling 600W consistently.

Hello.

For the past few days, I've been using a system with a 9850x3d, an RTX 5080, and 64GB of 6000 RAM. I've noticed that the CPU isn't performing as well as it should.

Without PBO, I’m getting an all-core clock speed of about 4.1 GHz (in Cinebench and games), and with PBO, it’s around 4.3 GHz. Something’s not right here, is it?

MSI B850 Gaming Pro WIFI6ME motherboard, latest BIOS

Settings -

PBO - Advanced

PBO Limits - Motherboard

Precision Boost Overdrive Scalar Ctrl - 10x

CPU Boost Clock Overeride (+) - 200 mhz

Maybe i am doing something wrong on my end, but it behaved like that in stock settings aswell

Edit - Tried using default bios settings -> all cores boost to 3.2 ghz 0.81 V at 46°C. CPU package drawage -> 120 W doesnt look normal either, no?
Only thing i turned on was EXPO settings
Core Boost -> Auto
Power plan -> ultimate
Eco Mode not activated

Tried a few more things, but im not getting more than 4.4 ghz all cores.
Using static oc is acting weird aswell. Tried 5.4 at 1.27 V draws around 200 W + i get even worse perfomance in games with my gpu only utilizing around 50%. might need to RMA

Sometimes i even need to restart my system, because it only does 0.6 ghz. Im confused https://gyazo.com/477031e444a0cb9151d4123cd9d4ef55

People keep telling me 144 Hz feels smoother than 60, but a spec sheet does not feel like anything. So I built a small page where you pick a frame rate and see the same animation run at 10, 20, 30, 60, 120 FPS right in your browser.

https://appdoesit.com/apps/fps-playground

What it does:

• renders a live 2D scene at the exact frame rate you pick, presets 10/20/30/60/120 or a custom slider from 1 to 240
• shows the measured FPS and frame time while it runs, so you watch it respond as you change the target
• in mouse mode the object follows your pointer, so you feel how your aim tracks at 30 vs 120
• shows your display max, so when 120 looks identical to 60, it tells you why (a 60 Hz panel caps around 60 measured)

I check the frame time meter every time I change a display setting, because that is the one that shows the stutter before I do.

No sign up, no tracking, nothing leaves the browser, the animation and the numbers are processed locally.

It is the first tool in a small catalog of free web utilities. Happy to answer questions about how the measured FPS is read, PM me if you want an embed on your site :)

I’m sure, like most here, w have been Afterburner folks for 10+ years. However, everywhere I go in 2026 (Reddit/discord/youtube) it seems mVOLT (and to a lesser extent the newer NVUV Play) are offering something totally new to OC/UV folks.

I have a 5090FE that I want to protect more than my wife given one seeming is exponentially harder to replace than the other these days.

With that said, what is “the way” these days to get those most out of this 5090FE will holding under 0.95v and under 500w of power?

Which Ram is Better?

Hi everyone. I have an Inno3D RTX 5080 (X3, air cooled) and I use mVolt+ for tuning. I only care about real gaming performance for daily use, not benchmark scores.

In demanding games the card sits at the 360 W limit a lot and the clock drops below what my curve allows. I know the BIOS override option in mVolt+ can raise the limit above 100%, and I’ve seen people mention values around 400-430 W.

Current settings (mVolt+ v0.50.4, driver 617.42):

• Core clock offset: +390 MHz
• Memory: +3000 MHz (passes memtest_vulkan with no errors)
• XBAR: +400 MHz, SYS: +350 MHz, Video: 0
• NVVDD (core) voltage limit: 800-950 mV (offsets REL/ALT-OP -125 mV)
• MSVDD (fabric) voltage limit: 800-1050 mV (offsets -25 mV), NVVDD/MSVDD ratio 1.00
• Voltage boost: 100%
• Power limit: 100% (360 W enforced / 360 W requested)
• OCP: NVVDD 300 A, MSVDD 120 A, board input current 36 A

Is it worth raising the power limit above 360 W for gaming? Real fps gains, not benchmarks

If yes, what is a sensible daily value (400? 420?) for an air-cooled card with a single 12V-2x6 connector?

What are the real risks: the connector/cable, the VRM, long-term wear? Is a moderate bump (~10-15%) basically safe, or does it carry real risk on this card?

Memory: I’m at +3000, which is the normal slider max. Does it make sense to go higher using the override, or is there a point where it stops helping or starts losing performance because of error correction?

I’m happy to skip it if the risk is more than small. Thanks!

Recentemente, percebi uma inconsistência visual no meu jogo que me fez perder bastante ELO. Fui investigar o problema e descobri algo preocupante no meu monitor LG 24GL600F-B, de 144 Hz, com painel TN.

O monitor aparentemente só funciona sem frame skipping em 60 Hz. Acima disso, os problemas se tornam insuportáveis, comprometendo minha experiência nos jogos competitivos.

Para verificar, fiz o teste neste site: https://keyboardtester.click/frame-skipping-test.php

Sinceramente, estou muito decepcionado. Paguei por um monitor de 144 Hz e agora estou considerando usar apenas 60 Hz por causa desse problema.

Alguém já passou por algo semelhante ou conhece alguma solução? Qualquer ajuda, sugestão ou experiência compartilhada será muito bem-vinda.

Desde já, agradeço a todos que puderem ajudar!

I don't have any clue what I'm doing

But my write bandwidth is quite low in comparison to the others

I tried to copy some other overclocker's timings from internet but I think I can't get it any lower

TDRWR_sg is capped at 36 if I try lowering it

Like I saw in some other intel overclocking to something like 10 my read and copy bandwidth gets destroyed to half

VDD and VDDQ = 1.440

VDD2 = 1.30

Vccsa = 1.20

Hey guys,
I'm wondering if I'm doing the right thing in using the best performance while being safe at the same time. I don't want to degrade my cpu but I don't want to use it in stock form either. I like to do some benchmarking score some times too.

My 9850x3d is at +200mhz and -35 curve now in all cores. Should I stop here on keep going to -40 curve? Should I fine tune per core?

The screenshot is from while I ran the cinebench 2026. Is there anything there that I should be concern regarding temp and voltage?

What's the "no go" voltage that I should prevent my cpu of reaching.

Thanks in advance!

I brought a Phenom II X6 1100T back to life—one I’d bought as scrap.

I installed CachyOS, overclocked it to 3.7GHz, compiled a k10-optimized tkg kernel, and ran God of War (2018), RDR2, the SH2 Remake, and other demanding titles.

(I also used Lossless Scaling.)

What do you guys think?

Hello,
I'm curious to know if there is any reason to flash an Astral vbios on an rtx 5080 prime when XOCD and MVolt are now available and you can unlock the power limit through the software?

I'm trying to understand whether I get anything from it. Thank you.

I have a Palit GameRock OC RTX 5080. I used mVolt+ 0.50.4 and set what I think are conservative values for some parameters, but I’d like to double‑check whether I limited the core voltage correctly and how you usually do it.

I ran the mvolt .exe file through VirusTotal and it flagged 4 viruses; I even executed it on my computer—is it actually dangerous?

Hello guys, hoping you're doing fine.

Today I want to share something that may affect your cards (?

I have released 3 tools:

1. A way to modify VBIOSes, so you can increase power limit, voltage, NVVDD offsets, MSVDD offsets (Blackwell 2.0), OCPs, fan channels, power per fan, core offsets more than 1000, VRAM offsets more than 3000, lower power limits (below 400W on a RTX 5090), lower clocks, etc. But as you know, these can't be flashed directly on the cards because falcon, right?
2. A custom VBIOS loader on Windows, that patches the registry file related to that GPU, it resets it and it's applied on every reboot. This does not change the real VBIOS on your card, but it just loads a copy via a patch and it let you use any modification!
3. A custom VBIOS loader on Fedora, that patches the GSP firmware start on memory, builds a separate boot entry and then rebuilds automatically with kernel updates. This does not change the real VBIOS either.

What are the requirements?

• Windows:
  • Windows 10 or 11, 64-bit.
  • NVIDIA driver 616.56 or newer (status shows the version).
  • A payload file for that exact GPU model (same PCI device ID).
• Linux:
  • A working NVIDIA 615.x driver or newer with the open kernel modules; nvidia-smi must list your GPUs.
  • The unpatched source of the open kernel modules for the exact installed version, for example: git clone --depth 1 --branch 615.78.08 https://github.com/NVIDIA/open-gpu-kernel-modules
  • Python 3.11 or newer, the headers for the running kernel (kernel-devel on Fedora), make, dracut, grub2-editenv and mokutil. With DNF5, also libdnf5-plugin-actions.
  • GRUB with GRUB_DEFAULT=saved and GRUB_ENABLE_BLSCFG=true (Fedora's defaults).
  • Secure Boot off, or your own module signing key: pass --signing-key and --signing-certificate to prepare.

You need to first get a copy of your VBIOS, you can do it with GPU-Z on Windows, or with nvflash on Linux.

Note that you can't modify EVERYTHING for the VBIOS, since it's still on research of what can be modified, what not and which rails are exposed. Also for example, VRAM timings can be modified (not on these tools) but they aren't applied, since the card reads it physically from the flash hardware.

So, some example pics!

First, some VBIOS editor example, for a RTX 5090 VBIOS, a RTX 4090 VBIOS, and a RTX 3090 VBIOS.

Then, the VBIOS loader on Windows looks like this:

Then you can choose a VBIOS, for example I will select a 671W VBIOS for the 4090.

And press OK/Accept, and a quick GPU restart after (no windows reboot), it works!

And it works just fine!

PS C:\Users\User> nvidia-smi -i 0 -pl 671

Power limit for GPU 00000000:05:00.0 was set to 671.00 W from 550.00 W.

All done.

On the other hand for Linux, the UI looks very similar, and steps are similar, but you can also guide yourself on the github repo!

You can edit the values you modified on MSI Afterburner, mvolt+ (recommended) on Windows. On Linux you can use LACT.

Tested GPUs that I own, and it works:

• RTX 6000 PRO MaxQ: Unlocked voltage (stock 0.9V) to 1.1V, power from 325W to 600W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz (it depends of your luck), and some OCPs.
• RTX 5090: PL from 600W to 800W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 5080: PL from 360W to 500W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 5070Ti: PL up to 450W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 4000 PRO SFF: PL from 70W to 105W, core offset to be able to do +2000Mhz, VRAM to be able up to +7000Mhz, unlocked voltage from 0.85V to 1.1V.
• RTX 5070: PL from 250 to 350W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 5060Ti: PL from 185W to 300W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 4090: PL up to 700W, core offset to be able to do +2000Mhz, VRAM to be able up to +6000Mhz.
• RTX 2000 Ada: PL from 70W to 105W, unlocked voltage up to 1.1V.
• RTX A2000 (Ampere): PL from 70W to 105W, unlocked voltage up to 1.1V.

Tested GPUs that I don't own, by other users:

• RTX 6000 PRO Workstation Edition
• RTX 5090
• RTX 5080 Laptop
• RTX 4070
• RTX 3060

For now, I can't seem to be able to edit Ada laptop variants (RTX 40 laptop series). Laptop Blackwell series (RTX 50 laptop series) can edit some parts of the VBIOS, but not all of them. Laptop Ampere series (RTX 30 laptop series) can edit almost everything.

And finally, the links are:

Custom VBIOS loader (Windows): https://github.com/Panchovix/nvidia-windows-vbios-vix-loader

Custom VBIOS loader (Linux): https://github.com/Panchovix/nvidia-linux-vbios-vix-loader

Everything is open source, so you can check the code to see if there are applicable fixes and such.

So if you guys can try, please let me know! If you find crashes on the vbios editor, or a specific GPU has info you can't edit and may be feasible to do so, you can raise an issue on github and I will check it out.

I'm an oldschool guy who has managed to get a 3rd gen I7 stable at 5.1 ghz stable 14 years ago which has been running smoothly ever since so i'd argue i'm not completely lost on the matter, but after the pump finally failed on my old rig i figured it's finally time for an upgrade.

ROG STRIX X870e-H

AMD Ryzen 7 9800X3D

Corsair Vengeance DDR6 2x16 GB 6400mhz

RTX 5080

I tried default values, "AI OC" setting, setting RAM frequency to 6000mhz and a number of different things, yet when stresstesting the system freezes after a short time.

In idle, and even under load it runs smootly most of the time but sometimes it crashes (not to a bluescreen or anything, it just turns off) when i'm starting an EXE for example. So not a high load scenario but i suspect it'll be a RAM isse.

I'm out of ideas. Did a decade and a half, since i've been out of the game, invalidate all my knowlege? Do i have bad hardware here?

Do i need to fuck around with RAM timings? Because i've never done that before.

Any input would be greatly appreciated.

So basically, I got AMIBCP, a bios Editor and looked around in the bios of my A320M. The stock bios had cpu ratio and bclk exposed. Core ratio didnt do anything but bclk did. After downloading and looking inside the latest version, bclk and ratio are hidden. If you make bclk visible, it doesn't do anything. However, in amd cbs there is pbo and curve optimizer. I sadly only have a 3350Ge and 3200g and a 5950x that is in my main pc that i dont want to disasemble so I cant really test it. Does anyone else have experience with bios modding?

What is the recommend max voltage of a 5080 aorus master for daily use?

Currently at 1050mv

Any settings shared would be appreciated

Okay, I have 9950X3D2:in a custom loop delidded, I also have PBO enabled with CO offsets between 20-35 between all 16 cores, also have boost behavior set to 200+ and PBO fully unlocked when no watt or amps limits.

I've noticed Ellen play CPU intensive games in 4k, maxed, that my CCD0 barely boost to 5.4Ghz while gaming, at like 1.345v while being around 48c.

Is this the average clock speeds for an AMD CPU with 3D Vcache? Or am I missing a setting.

I delided my cpu applayed LM like 3 times atp used many q tips etc etc but my die still has so much residue what do i do to remove it ?
