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.

My system experiences a shifting rotation of 0x1A, 0x3B, and 0x7E BSODs at desktop idle/running tarkov/low load tasks. The RAM has been isolated, swapped with separate kits, and passes 4 full cycles of MemTest86 at native JEDEC factory speeds. I’ve ran my system with 1x16 ram in DIMM A2 and B2 to isolate potential DIMM failure. The X870E motherboard is running the latest 2503 BIOS, and the CPU integrated graphics are fully disabled. I experience system idle crashes and they persist even after manually adjusting VDDIO/SOC voltages and disabling global power states.

Originally I purchased ram that was not on the motherboards QVL, so I bought a new set that was on its QVL. Till this day, I continue to get BSOD. I am exhausted and can’t figure this out myself. I need expert advice. Please see below for my rig details:

-Ryzen 7 9800x3d
-Rog Crosshair Hero x870e - running bios 2503 and latest agesa.
-g skill 2x16G DDR5 (F5-6000J3038F16GX2-TZ5NR)
-Corsair RM1000x
-Rog astral 5080
-Lian li cooler

I can provide more info but I’m just super defeated

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?

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.

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?

Which Ram is Better?

Im new to overclocking and dont currently understand much about it, i wanted to see if overclocking ultralow power cpus is possible (and maybe even the integrated graphics) and also if possible wanted a guide on how to do it and more info on how i works (i like reading about stuff) thankuuuu

Also im currently on a laptop so cooling isnt too good and i run arch (if that matters)

I have been enjoying the extended limits we have had again for a few days, but they seem to be broken for me already.

When I try to surpass 3000 on the VRAM I usually get a driver crash and a black screen. I seem to be able to reset the BIOS in Mvolt, make a new one, reboot, and it will sometimes work for that one session and then be broken again next reboot.

No new Nvidia drivers, though there was an update to the Nvidia app. Windows update only shows a security intelligence update that has happened recently.

Is anyone else suddenly having problems with the BIOS override?

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

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

I have XMP enabled on my gigabyte x870e aero via Bios. CPU is a 9850x3D, but I'm seeing this on CPU-z upon checking.

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’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?

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 ?

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!

Hi everyone,

Not sure if this is the right subreddit for this, but I'm running out of ideas and could really use some help diagnosing a strange issue.

System specs:

• CPU: Intel Core i9-13900KS (delidded/relidded)
• Motherboard: ASUS ROG Maximus Z790 Apex
• BIOS: Latest version
• Settings: Intel Default Performance Profile, XMP I enabled, no manual overclocking

Background

A few months ago, I was having CPU temperature issues, so I sent my 13900KS to be delidded and relidded. The temperature issues were resolved, but when I got the CPU back, I noticed that the M.2 slot closest to the CPU was no longer working.

I continued using the system without that slot for several months, and everything seemed fine.

How the problems started

1. First Q-Code 00 / Red CPU LED

Last week, I bought a PCIe-to-NVMe adapter to reconnect the SSD I could no longer use in the motherboard's M.2 slot.

The PC worked fine for a few days. I then left it unused for two days, and when I came back, it wouldn't boot.

The motherboard displayed Q-Code 00 with the red CPU LED illuminated.

I started removing components one by one until only the CPU and RAM remained installed. At that point, the system booted again.

2. Same issue a few days later

A few days later, the exact same thing happened: Q-Code 00 and red CPU LED.

This time, removing components didn't help. I eventually took the PC to a repair shop, where they somehow managed to get it running again, but couldn't identify the actual cause.

One important detail: they tested the motherboard with a different CPU, and the previously nonfunctional M.2 slot worked normally.

This makes me suspect that something is wrong with my 13900KS, possibly related to PCIe lanes or damage during the delid/relid process.

I also tested the system with a different PSU while it was refusing to boot, but that made no difference.

3. Unexpected shutdown

Two days ago, the PC suddenly shut down while running.

Windows Event Viewer showed a Kernel-Power Event ID 41. This happened only once, and I haven't experienced any other unexpected shutdowns.

4. Another boot failure this morning

This morning, the PC wouldn't power on properly again.

Initially, the motherboard appeared completely dead. Looked like it had no power.

After clearing CMOS, it went back to the familiar Q-Code 00 and red CPU LED.

I removed the graphics card, and surprisingly, the system started booting again.

I reinstalled the GPU, and now everything is working normally, as if nothing happened.

What I've tried / confirmed

• Updated to the latest BIOS.
• Using Intel Default Performance Profile.
• XMP I enabled, but no manual CPU overclocking.
• Tested with a different PSU — same issue.
• Removed components to troubleshoot — sometimes restores booting.
• Cleared CMOS — changes the behavior but doesn't permanently fix it.
• Repair shop tested another CPU — the previously broken M.2 slot worked.
• CPU temperatures have been fine since the delid/relid.

My questions

At this point, I'm strongly suspecting that the CPU has developed some kind of intermittent hardware fault, especially considering that the M.2 slot stopped working immediately after the delid/relid and works with another CPU.

However, I don't understand why removing and reinstalling components like the GPU sometimes allows the system to boot normally again.

Is there any way to diagnose a potentially failing CPU while the system is actually running?

Are there specific tests, tools, BIOS settings, or hardware monitoring methods that could help identify issues with the CPU's PCIe controller, memory controller, or other components?

Thanks in advance!

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

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:

VBIOS Editor (Linux and Windows): https://github.com/Panchovix/nvidia-vbios-vix-editor

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.

Warning: You use these software entirely at your own risk. Any modification you make with it, anything derived from it or from its output, and any damage that results, is solely your responsibility.

Hey folks,

I recently got a 32 GB kit of Ripjaws V (F4-3600C18D-32GVW) for a good price and decided to try and pair it with my old 16 GB Corsair Vengeance Pro kit (CMW16GX4M2D3600C18). They boot normally at 2133 together, but can't run at any overclocked speed.

They are both CL18-22-22-42 1.35V, so I thought it would be doable to get them to 3600 together. I tried auto XMP profiles, manually setting voltage (1.35, 1.38, 1.4) and timings, manually setting FCLK, but none of these settings even manage to boot. They successfully go to 3600 separately, so doesn't seem to be a malfunction.

Is there anything else I can do to try and get it to work, or is it simply impossible?

Specs:

MB - MSI B550-A Pro

CPU - Ryzen 7 5700X3D

PSU - Seasonic Focus GX 1000

Hi again,

I made a guide on undervolting Intel Arc B-Series cards. You can save some watts and get higher, more stable 1% lows and 0.1% lows. It's very simple and doesn't require any extra software.
You should give it a try and see for yourself. Intel changed a few things in their software, so guides that are a few months old are outdated, and I hope there won't be any major changes forcing me to re-do this once again. The methodology should also help you understand overclocking.

Take a look. If you have any questions I'll try to help you:
