XTREME MEMORY
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.
  1. Instantly upgrade memory performance
  2. Overclock Native and XMP 3.0 DDR5 memory to higher frequency easily
  3. No need to input dozens of memory parameters such as clock, voltage and timings
  4. Built-in wide variety pre-tuned profiles database for different memory IC vendors
*DDR5 MEMORY UPGRADE involves DDR5 memory overclocking, overclocking capability depends on users' hardware configuration
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
