Performance
Memory & Storage

DRAM Overclocking Performance
Comprehensive memory tuning options are the cornerstone of TUF GAMING motherboards. With the motherboard, you can extract all the potential out of your DDR5 modules*, whether they're from an extreme-speed kit or an entry-level set that would otherwise be locked.
* Memory overclocking may vary between CPU series. Please refer to the spec table for detailed information.

DDR5 DOMINANCE
For those who want to fly past stock DDR5 speeds, this motherboard is primed and ready for enthusiast-grade kits, courtesy of vast AMD Extended Profiles for Overclocking (EXPO™) support. Seasoned veterans can further tweak performance via an extensive array of settings in the UEFI.

ASUS AEMP
ASUS Enhanced Memory Profile (AEMP) is an exclusive firmware feature for PMIC-restricted memory modules. AEMP automatically detects the memory chips on your kit and then presents optimized frequency, timing and voltage profiles that you can quickly apply.

M.2 PCIe 5.0 Support
This motherboard also features one PCIe 5.0 M.2 slot to enjoy the fastest data transfers of up to 128 Gbps*, and all M.2 slots support NVMe RAID configurations to take advantage of the latest available speeds.

DIY
Easy PC DIY

PCIe Slot Q-Release
A physical lever unlocks the first PCIe slot’s security latch with one tap, greatly simplifying the process of detaching a PCIe card from the motherboard when it’s time to upgrade to a new GPU or other compatible device.

Q-Antenna
With Q-Antenna, attaching a WiFi antenna to your PC is now easy and fast. Instead of slowly rotating two fasteners until they finally lock in, they just snap into place. Less hassle, and more consistent performance.

M.2 Q-Latch
The innovative ASUS Q-Latch makes it easy to install or remove an M.2 SSD without the need for specific tools or screws. This design employs a simple locking mechanism to secure the drive and neatly detach it with one tap.

Q-LED
The on-board Q-LED troubleshooting lights give PC builders a quick indicator to confirm that key components ― CPU, RAM, graphics card, storage devices ― are functioning normally during startup. It can also alert them when memory modules have not been properly installed--even before booting.

Clear CMOS & BIOS FlashBack™
The Clear CMOS button quickly resets Bl0S settings to factory default. lt can also be used to reboot the PC if incorrect Bl0S settings have been selected.
Bl0S FlashBack™ is a safe and simple way to update Bl0S. Just drop the (UEFI)BlOS file onto a FAT32-formatted USB stick, plug it into the USB BlOS FlashBack port, and press the button. Updates can even be performed without having memory or a CPU installed.

Pre-mounted I/O shield
Our pre-installed I/O shield safeguards ports, simplifies the build process, increases functionality and enhances aesthetics for PC DIY enthusiasts.

It features an unprecedented 120 dB signal-to-noise (SNR) ratio for the stereo line out and a 113 dB SNR for the line in, providing pristine audio quality. Additionally, an impedance-sensing circuit automatically adjusts gain to ensure an optimal volume range for your headphones.

DTS Audio Processing
DTS® Audio Processing enhances gaming headset and speaker audio experiences by reducing distortion and by providing deeper bass, so games, movies and music sound better. It also allows you to customize audio settings.

Lighting

Outshine The Competition
ASUS Aura Sync offers synchronized lighting with other Aura Sync products, including motherboards, graphics cards, monitors and peripherals.

Addressable RGB Gen 2 header
Automatically optimize lighting effects for the number of LEDs present in compatible ARGB gear.
