With 2-DIMM daisy chain memory trace layout, Z790 AORUS TACHYON can achieve the shortest memory DIMM distance between CPU, therefore reach the highest memory clock and the lowest latency.

1.Shielded Memory Routing
All memory routing is under the PCB inner layer shielded by a large ground layer to protect from external interference.
2. Impedance Optimized Topology
By optimizing memory trace width, length and style from HPC simulation to actual implementation, overall impedance is lowered between CPU memory controller and memory modules to achieve higher DDR5 speed.
3. Low Signal Loss PCB
Server grade mid-loss or low-loss PCB material is chosen to lower signal loss inside PCB and maintain DDR5 high speed signal transmission.
DDR5 Auto Booster
Automatically Boost the Native DDR5 frequency to 5000MHz while the system is under heavy loading by a single click.

DDR5 Memory Upgrade
GIGABYTE BIOS offers pre-defined and retrievable profiles for users to get higher performance easily. The profiles are based on a database that is created by checking each memory IC and PMIC vendors to optimize the modules to unleash their full potential. This is a time saving feature to manually configure overclocked DDR5 memory kits.
- Instantly upgrade memory performance
- Overclock Native and XMP 3.0 DDR5 memory to higher frequency easily
- No need to input dozens of memory parameters such as clock, voltage and timings
- Built-in wide variety pre-tuned profiles database for different memory IC vendors

XMP 3.0 User Profile
Define and create your own SPD profile into Native and XMP 3.0 memory modules or apply the pre-tuned profiles to XMP 3.0 User Profile. Two user-defined profiles can be saved, loaded either locally or from/to an external storage device.
• Two empty SPD profiles can be defined by users and carry to next computer
• Transfer DDR5 XMP Booster profiles into XMP 3.0 User Profiles
• Quick memory performance simulation based on user input clock and timing parameters
• Profile save and load function to share your memory parameters online

Design Ready for PCIe 5.0
PCIe 5.0 Design supports double the bandwidth of PCIe 4.0 and ensures that compatible with cutting-edge SSDs and GPUs released in the next few years to their full capability.

The New Generation Ultra Durableâ„¢ SMD PCIe 5.0 Armor

2. Power Button
- Power On/Off system.
3. CPU Ratio Switch
- Raise or lower CPU ratio manually.
4. Cold Reset Button
- Use this button to force your system to reboot. This is usually used if a CPU crash or memory errors occur or warm reset doesn't work when tuning your system settings. Hitting this button to force the system to shutdown and boot again.
5. Clear CMOS
- Clear BIOS setting.
6. Reset Button
- Reboot system.
7. SB Switch
- The SB switch allows enabling or disabling of the Dual BIOS function.
8. BIOS Switch
- The BIOS switch (BIOS_SW) allows users to easily select a different BIOS for boot up or overclocking, helping to reduce BIOS failure during overclocking.
9. OC Trigger Switch
- This switch can be used to lower the CPU frequency to cool down the CPU temperature before running a benchmark without having to change any software settings. Instantly setting the TGR switch back to its default position when the benchmark begins will revert the CPU frequency to the original value.
10 OC Ignition
- The OC Ignition button allows overclockers and DIY users to pre-test water cooling setups when building up their computers without needing to boot the system. It also allows the system fans to keep spinning at a low temperature and allows for a firmware update even without a CPU installed.
11. Voltage Measurement
- Use multimeter to contact those points to measure different voltage value.
