Download Universal x86 Tuning Utility for Windows

Yes. UXTU is completely free and open source under the GPL-3.0 license. There are no paid tiers, no feature locks, no ads, and no bundled software.

Here is what “free” means in practice:

• No premium version — Every feature in the application is available to all users at no cost, including Curve Optimizer, Adaptive Mode, and per-game profiles.
• No registration or account required — Download the MSI or ZIP and run it. No email, no sign-up, no license key.
• No ads or telemetry — UXTU does not display ads, does not collect usage data, and does not phone home for any reason.

The developer (JamesCJ60) accepts optional donations through Patreon and PayPal to fund ongoing development. Donating is entirely voluntary and does not unlock additional features. You can download the latest release from our download section or the official GitHub releases page.

Yes. UXTU is safe to use on both Windows 10 and Windows 11, including the latest 23H2 and 24H2 builds. The full source code is publicly available on GitHub and has been reviewed by thousands of users.

Why antivirus tools sometimes flag UXTU:

• UXTU uses the WinRing0 kernel driver to access CPU registers for hardware tuning. Some antivirus programs flag this driver as “potentially unwanted” because kernel-level access is a sensitive operation.
• This is a known false positive. The same WinRing0 driver is used by trusted tools like HWiNFO64, CPU-Z, and Open Hardware Monitor.
• If your antivirus blocks UXTU, add the application folder to your exclusion list. On Windows Defender: Settings → Privacy & security → Virus & threat protection → Manage settings → Exclusions → Add folder.

Why SmartScreen shows a warning: UXTU is not signed with a paid code-signing certificate ($200-400/year), so Windows SmartScreen displays a blue warning on first run. Click “More info” then “Run anyway” to proceed. This is standard for most open-source utilities.

UXTU supports both Intel and AMD processors, though AMD support is more extensive.

AMD support (Zen 1 through Zen 4):

• Full TDP control (STAPM, fast limit, slow limit)
• Curve Optimizer with per-core voltage offsets
• iGPU clock speed and power limit adjustment
• VRM current control (EDC/TDC limits)
• Temperature limit control
• Adaptive Mode with dynamic TDP

Intel support (4th gen Haswell through Meteor Lake):

• TDP adjustment (PL1/PL2 limits)
• Temperature limit control
• Basic power management

Intel-specific features like per-core undervolting via voltage offset are not yet available in UXTU. If you run an Intel system and need advanced undervolting, ThrottleStop remains the stronger option for that specific task. Many users run both tools together — ThrottleStop for voltage control and UXTU for TDP, Adaptive Mode, and game profiles.

Under normal use, no. UXTU operates within the parameters your processor’s firmware allows. It does not bypass hardware safety limits.

What can happen with aggressive settings:

• System crash (BSOD) — The most common result of pushing Curve Optimizer offsets too far. Fix: reboot. The system returns to stock settings.
• Application freeze — Some apps may hang if undervolting causes a core to become unstable under specific workloads. Fix: back off your voltage offset by 5.
• Accelerated wear — Running at maximum TDP with thermal limits disabled for months could theoretically shorten component lifespan. In practice, the premade presets and Adaptive Mode prevent this.

Key safety detail: UXTU settings are stored in software, not flashed to BIOS. A restart always returns your CPU to factory defaults. There is no risk of bricking your system or being stuck with bad settings — just reboot if anything goes wrong.

Tip: Start with premade presets. They have been tested across many systems. Only move to Custom Presets and Curve Optimizer after you understand how each parameter affects your hardware.

Undervolting in UXTU is done through the Curve Optimizer feature on AMD Zen processors. It reduces CPU voltage to lower temperatures and power consumption without sacrificing clock speed.

Step-by-step process:

1. Open UXTU and go to Custom Presets.
2. Scroll to the Curve Optimizer section.
3. Set a conservative starting offset of -10 for all cores.
4. Click Apply and run a stress test (Cinebench R23, AIDA64, or Prime95) for 30 minutes.
5. If the system stays stable, increase the negative offset to -15 and test again.
6. Continue in increments of -5 until you see a crash or BSOD.
7. Back off by 5 from the crash value — that is your stable all-core offset.

For per-core tuning (best results): After finding your all-core limit, test each core individually. Some cores are “golden” and can handle -25 or -30, while others may only manage -10. Per-core tuning takes more time but yields lower temperatures overall.

Note for Intel users: UXTU does not currently support per-core voltage offsets on Intel processors. If you need Intel undervolting, use ThrottleStop for voltage control and UXTU for TDP management.

Adaptive Mode is an intelligent TDP algorithm that adjusts your CPU’s power limit based on real-time temperature readings, instead of locking you into a static wattage value.

How it works:

1. You set a target temperature (e.g., 80°C).
2. The algorithm monitors CPU temperature continuously.
3. When thermals are cool (light workload), it raises TDP for faster response.
4. When temperature climbs near the target (heavy workload), it lowers TDP to prevent overheating.

Why it is better than a static preset:

• A static 25W preset wastes headroom during light tasks and may overheat during heavy bursts. Adaptive Mode uses all available thermal headroom when it exists and backs off when it doesn’t.
• Particularly effective during gaming, where workload intensity fluctuates between menus (light) and gameplay (heavy).

V3 Beta — AutoOC: The upcoming V3 release adds AutoOC, which goes further by using machine learning to find optimal Curve Optimizer offsets. It monitors hardware error events in real time and adjusts voltage offsets automatically, removing the manual trial-and-error process entirely.

By default, no. When you shut down or restart, your CPU reverts to stock settings because UXTU changes are applied at the software level, not written to BIOS firmware.

To make settings persistent, enable two options in UXTU Settings:

1. Start with Windows — Adds UXTU to your startup apps so it launches at boot.
2. Apply last preset on startup — Tells UXTU to reapply your most recent tuning profile the moment it launches.

With both enabled, UXTU starts in the system tray at boot and immediately applies your saved preset. The whole process takes about 2-3 seconds after login.

Safety benefit of this design: If UXTU crashes, gets uninstalled, or fails to start, your CPU runs at factory defaults. There is no risk of being stuck with unstable settings after a bad undervolt — just reboot without running UXTU and everything reverts.

Startup crashes are usually caused by one of three things. Work through these fixes in order:

1. Antivirus blocking the WinRing0 driver

• Bitdefender, Kaspersky, Norton, and some other tools flag the kernel driver that UXTU uses for hardware access.
• Fix: Add the entire UXTU folder to your antivirus exclusion list. On Windows Defender, go to Settings → Virus & threat protection → Exclusions → Add folder.

2. Corrupted configuration files

• If UXTU was closed during a save operation, its JSON config files may be corrupted.
• Fix: Navigate to the UXTU application directory and delete any .json files that store preset data. The app regenerates default configs on next launch. Your saved presets will be lost — another reason to back them up regularly.

3. Missing .NET 7.0 Desktop Runtime

• UXTU V2.x requires .NET 7.0 specifically, even if you have .NET 8.0 installed.
• Fix: Download and install .NET 7.0 Desktop Runtime from Microsoft. It coexists with other .NET versions without conflict.

If none of these resolve the issue, try the portable ZIP version instead of the MSI installer. You can also search the GitHub Issues page for your specific error message — the developer actively responds to bug reports.

Some laptop manufacturers lock power management in BIOS firmware, which overrides software-level TDP changes from tools like UXTU. This is most common on certain Lenovo Legion, HP Victus, and Dell G-series models.

Troubleshooting checklist:

1. Confirm administrator rights — Right-click the UXTU shortcut and verify “Run as administrator” is enabled. Without admin access, settings appear to apply in the UI but actually do nothing at the hardware level.
2. Monitor with HWiNFO64 — Open HWiNFO64, go to the sensors panel, and watch the “STAPM Power” or “CPU Package Power” reading. Apply a UXTU preset and check whether the power value changes. If it stays the same, BIOS is likely blocking the adjustment.
3. Check for BIOS power locks — Some BIOS versions have a “Performance Mode Lock” or “Power Management” setting that restricts third-party tools. Look in your BIOS advanced settings or security tab.
4. Update BIOS — Some manufacturers add or remove power management restrictions in BIOS updates. Check your laptop manufacturer’s support page for the latest version.
5. Try Adaptive Mode instead — On some locked systems, Adaptive Mode still works because it adjusts limits within the existing BIOS-allowed range rather than trying to override BIOS-imposed caps.

If none of these work, your laptop’s firmware may hard-lock power settings. Check the UXTU Discord server for reports from other users with the same model — there may be a known workaround.

UXTU works on both desktops and laptops. The full feature set is available on both, though some features are more relevant to one form factor.

Most useful on laptops:

• TDP control (STAPM, fast/slow limits) — manages power in thermally constrained chassis
• Temperature limit adjustment — reduces keyboard/palm rest heat
• Adaptive Mode — dynamic TDP for varying workloads
• Battery-source Automations — switches to Eco on battery, Performance on AC

Most useful on desktops:

• Curve Optimizer undervolting — lower temperatures and power draw
• NVIDIA GPU overclocking — core and memory clock adjustments
• Per-game profiles — automated tuning per application

Mini PC users (Intel NUC, Beelink, MinisForum) benefit from both sets of features since compact cases have cooling constraints similar to laptops.

UXTU V2.x does not have a built-in auto-updater. Here is how to update using each installation method:

MSI Installer:

1. Download the new MSI from our download section or GitHub releases.
2. Run the installer. It detects the existing installation and upgrades in place.
3. Custom presets (stored as JSON) are preserved automatically during MSI upgrades.

Portable ZIP:

1. Download the new ZIP file.
2. Back up your .json preset files from the current folder.
3. Extract the new ZIP to the same directory, overwriting existing files.
4. Copy your preset files back if they were overwritten.

Winget:

• Run winget upgrade JamesCJ60.Universalx86TuningUtility in any terminal.
• Winget handles the download and in-place upgrade automatically.

Tip: Follow the GitHub releases page (click “Watch” → “Releases only”) to get notified when new versions drop.

Yes, and this is one of the most popular reasons people install UXTU. Lowering your CPU’s TDP directly reduces power consumption, which extends battery runtime.

How to set it up:

1. Apply the Eco preset or create a custom preset with TDP set to 10-15W (for most Ryzen laptops).
2. Go to Automations and create a rule: “When power source changes to Battery, apply Eco preset.”
3. Create a second rule: “When power source changes to AC, apply Performance preset.”
4. For maximum savings, also lower the iGPU clock speed and set a conservative temperature limit (70°C) to keep fan speed — and therefore total system power draw — as low as possible.

Real-world results: Users on r/AMDLaptops regularly report gaining 30 to 90 minutes of additional battery life depending on the laptop model and workload. The biggest gains come from laptops whose manufacturers set aggressive default TDP values that burn through battery even during light tasks like web browsing.

Tip: Test your baseline battery life with a tool like BatteryBar before applying UXTU, then test again after. This gives you a concrete before/after comparison instead of guessing.

It depends entirely on your processor brand and what you need to tune.

Choose UXTU if:

• You have an AMD processor — ThrottleStop does not support AMD at all.
• You want per-game profiles or automation rules — ThrottleStop lacks both features.
• You use both Intel and AMD machines and want a single tool with a unified interface.
• You want Adaptive Mode for dynamic, temperature-based TDP management.

Choose ThrottleStop if:

• You have an Intel processor and need per-core undervolting via voltage offset — ThrottleStop has deeper Intel voltage control than UXTU.
• You need SpeedShift tuning or C-state management — advanced Intel power states that UXTU does not expose.
• You want the most mature, battle-tested Intel tuning tool available.

Use both together: Many Intel laptop users run ThrottleStop for voltage control and UXTU for TDP limits and Adaptive Mode. The two tools can coexist, though you should avoid adjusting the same parameter in both.

AMD Ryzen Master is the official AMD overclocking tool. It is polished and well-supported, but has a narrower scope than UXTU for most users.

Where UXTU wins:

• Laptop TDP control — Ryzen Master focuses on desktop processors and does not support STAPM or fast/slow limit tuning on laptops. UXTU was built specifically for this.
• Portability — UXTU has a portable ZIP option; Ryzen Master requires a full install.
• Per-game profiles and Automations — Ryzen Master has no per-application profile switching or event-based automation.
• Adaptive Mode — Dynamic TDP based on temperature is unique to UXTU.

Where Ryzen Master wins:

• Desktop overclocking depth — Per-CCX multiplier tuning, memory timing control, and detailed per-core monitoring for desktop Ryzen chips.
• Official AMD support — Signed driver, official documentation, and AMD customer service backing.

Bottom line: For laptop users, UXTU is the better tool. For desktop users doing serious overclocking with memory tuning, Ryzen Master provides more granular control. For desktop users who just want undervolting and TDP adjustment, UXTU covers the basics well.

No. The Ryzen 7045HX (Dragon Range) series is explicitly not supported by UXTU. This includes the Ryzen 9 7945HX, Ryzen 7 7745HX, Ryzen 5 7545HX, and related SKUs.

Why it is not supported:

• Dragon Range processors use a different power management architecture than standard Zen 4 mobile chips (Phoenix).
• The RyzenAdj backend that UXTU V2.x uses for AMD tuning cannot communicate with Dragon Range’s power management controller.
• UXTU will either fail to detect the processor or display settings that do not actually apply.

Future support: The V3 beta introduces a new PawnIO driver backend that replaces WinRing0. This new driver architecture may eventually enable Dragon Range support, but there is no confirmed timeline. Monitor the GitHub repository for updates.

Alternative for Dragon Range users: For basic TDP control on 7045HX laptops, check the manufacturer’s built-in power management (Lenovo Vantage, ASUS Armoury Crate, etc.) or use RyzenAdj directly from the command line with the correct SMU arguments for your specific chip.

UXTU V2.x was compiled against the .NET 7.0 Desktop Runtime. Having .NET 8.0 installed does not satisfy the .NET 7.0 requirement because .NET versions are not backward-compatible for desktop applications.

How to fix it:

1. Go to the Microsoft .NET 7.0 download page.
2. Download the .NET Desktop Runtime 7.0 (not the SDK, not the ASP.NET runtime — specifically the Desktop Runtime).
3. Install it. The process takes under a minute.
4. Both .NET 7.0 and 8.0 coexist on the same machine without conflict.

When this will stop being an issue: The V3 beta (currently in development) targets .NET 8.0. Once V3 reaches stable release, users with .NET 8.0 will not need a separate runtime. Until then, installing .NET 7.0 alongside your existing runtimes is the easiest fix.

Uninstalling UXTU is straightforward and leaves no permanent system changes behind.

MSI version:

1. Open Windows Settings → Apps → Installed apps.
2. Search for “Universal x86 Tuning Utility.”
3. Click Uninstall and follow the prompts.
4. This removes application files, desktop shortcut, Start Menu entry, and registry entries.

Portable version:

• Simply delete the folder containing the extracted files. There is nothing to uninstall since the portable version does not write to the registry or system folders.

After removal: Restart your computer. This ensures the WinRing0 kernel driver is fully unloaded and all CPU settings revert to stock values. Without a restart, the driver may remain loaded in memory until the next reboot.

Cleaning up leftover data: If you want to remove saved presets and config files, check for JSON files in the UXTU application directory (for MSI installs, typically C:\Program Files\Universal x86 Tuning Utility) and in %AppData% before deleting.

UXTU and UXTU Handheld are two separate applications built by the same developer (JamesCJ60) for different device types.

UXTU (Standard):

• Designed for laptops and desktops with keyboard/mouse input
• Standard WPF interface with sidebar navigation
• Full feature set: presets, Custom Presets, Adaptive Mode, Game Library, Automations, Curve Optimizer

UXTU Handheld:

• Designed for handheld gaming PCs like the ROG Ally, Lenovo Legion Go, Ayaneo, GPD Win, and similar devices
• Touch-friendly interface with larger controls optimized for small screens (7-8 inch)
• Device-specific features: TDP profiles linked to game mode buttons, controller-aware UI elements
• Simplified workflow tailored to handheld use cases

Which one to download: If you have a standard laptop or desktop, download regular UXTU from our download section. If you own a handheld gaming PC, download UXTU Handheld from its separate GitHub repository.

Yes. UXTU works completely offline after installation.

What works without internet:

• All tuning features (presets, Custom Presets, Adaptive Mode, Curve Optimizer)
• Per-game profiles and Automations
• System information display
• NVIDIA GPU tuning
• Saving and loading custom presets

What requires internet:

• Downloading the installer or ZIP initially
• Checking for updates (manual process — there is no auto-updater)

The app does not phone home, does not require license activation, does not collect telemetry, and does not download data during use. This also means UXTU does not auto-update — you need to check the GitHub releases page or our download section manually when you want a newer version.

This is a known issue reported on GitHub where the iGPU power cap unexpectedly drops to 15W, causing stutters and frame drops in games that rely on integrated graphics.

What causes it: On AMD APUs, the CPU and iGPU share a single power budget. If the CPU’s TDP fast limit is set too low, the system allocates most of the power envelope to CPU cores, starving the iGPU.

How to fix it:

1. Go to Custom Presets.
2. Explicitly set the iGPU power limit to your desired value (25-30W is typical for gaming on Ryzen 6000/7000 APUs).
3. Make sure the CPU TDP fast limit is high enough to accommodate both CPU and iGPU power draw. For example, if your CPU needs 15W and your iGPU needs 25W, set the fast limit to at least 40-45W.
4. If the issue persists, apply a premade Performance or Extreme preset first to raise all limits, then adjust iGPU settings from that higher baseline.

Background: On shared APU designs, the STAPM budget is divided dynamically. UXTU lets you control the allocation, but you need to account for both CPU and iGPU workloads when setting limits. Setting the CPU TDP too high relative to the total budget can inadvertently starve the iGPU.
