Power Architecture Power Design Efficiency Advanced Thermal Design with Integrated IO Armor MOSFET Heatsink Enlarged heatsink surface area improves thermal performance by increasing heat dissipation surface and maintain stylish aesthetic. Grooved for Air-Flow Grooved for Air-Flow and Increase Total Contact Surface. Thick Thermal Pad Improved thickness of the thermal pad to 1.5mm, gives superior heat dissipation of MOSFETs. Smart Fan 6 Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. 2 - Slope/Stair dual graph mode - Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval. 4 - EZ Tuning - Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve. 5 - Fan curve profile - Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS. FAN STOP Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking. Support for DDR4 XMP Up to 4800MHz and Beyond* GIGABYTE is offering a tested and proven platform that ensures proper compatibility with profiles up to 4800MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on their GIGABYTE motherboard. * XMP Profile support may vary depending on memory module. Product features may vary by model. Shielded Memory Routing All memory routing is under the PCB inner layer shielded by a large ground layer to protect from external interference. * Photo for reference only Memory Layout - Daisy Chain Design With the optimized daisy-chain routing, the Z590 Ultra Duable motherboard provides a proven speed of up to DDR4-4800+ MHz with high-density Memory module*. Optimized daisy-chained routing eliminates the stub effect, pushes the one DIMM per channel in dual channel interleaving mode to hit higher memory frequencies, providing professional gamers a denser and faster system memory experience. *Performance may vary in circumstances.
