Choosing the right motherboard is crucial for building a high-performance multi-GPU gaming or rendering setup. The Gigabyte Z790 Aorus Elite AX has garnered attention for its features and capabilities. But is it the right choice for a multi-GPU configuration? This article explores the key factors to consider.

Overview of the Gigabyte Z790 Aorus Elite AX

The Gigabyte Z790 Aorus Elite AX is a mid-range motherboard designed for Intel's latest 13th and 12th generation processors. It features the Z790 chipset, supporting advanced connectivity options, robust power delivery, and a sleek design. Its compatibility with PCIe 4.0 and PCIe 5.0 makes it suitable for high-speed graphics cards and SSDs.

Multi-GPU Support: What to Know

Multi-GPU setups, typically using NVIDIA SLI or AMD CrossFire, require specific motherboard features. Not all motherboards support multi-GPU configurations effectively. For the Z790 Aorus Elite AX, support depends on:

  • The number and placement of PCIe x16 slots
  • BIOS support for multi-GPU configurations
  • Power delivery and cooling solutions
  • Driver and software support from GPU manufacturers

PCIe Slots and Layout

The motherboard offers two PCIe x16 slots, both capable of running at x16 bandwidth when used with compatible CPUs. However, running two GPUs at full x16 speeds simultaneously may depend on the CPU and BIOS settings. The physical spacing and slot configuration are also important for adequate cooling and airflow.

BIOS and Software Support

BIOS support for multi-GPU configurations is essential. The Z790 Aorus Elite AX provides a UEFI BIOS with options to enable or disable multi-GPU modes. However, the effectiveness of multi-GPU support varies by GPU brand and driver updates. It’s important to verify that the motherboard BIOS is up-to-date and supports your specific GPU setup.

Performance and Limitations

While the Z790 Aorus Elite AX offers solid features, users should be aware of potential limitations:

  • Limited PCIe x16 slots for multi-GPU configurations compared to high-end motherboards.
  • Multi-GPU scaling may not be optimal for all applications, especially with newer games that favor single GPU setups.
  • Potential compatibility issues with certain GPU combinations or driver versions.

Is It a Good Choice for Multi-GPU Setups?

The Gigabyte Z790 Aorus Elite AX can support multi-GPU configurations, but it may not be the best option for demanding multi-GPU workloads. It is suitable for users who want a reliable motherboard with multi-GPU support for specific tasks like rendering or scientific computing, provided they are aware of its limitations.

Recommendations

  • Check compatibility with your chosen GPU brands and models.
  • Update BIOS to the latest version for optimal multi-GPU support.
  • Ensure your power supply can handle multiple high-end GPUs.
  • Consider a motherboard with more PCIe x16 slots if you plan to expand beyond two GPUs.

In conclusion, the Gigabyte Z790 Aorus Elite AX offers a good balance of features and performance. However, for intensive multi-GPU setups, evaluating higher-end motherboards designed explicitly for multi-GPU scaling might be advisable.
