## Summary description

ASRock Z790 Pro RS is an ATX desktop motherboard with Intel Z790 chipset and LGA 1700 socket for one Intel processor (compatible with Intel Core i7 series). It supports DDR5 memory across 4 DIMM slots (up to 128 GB, dual-channel, non‑ECC), offers 2.5 Gigabit Ethernet (Dragon RTL8125BG), Realtek ALC897 7.1 audio, multiple USB 3.2 and USB 2.0 ports, HDMI and DisplayPort outputs, M.2 and eight SATA III connectors, RAID support and UEFI AMI BIOS.

## Long description

The Race Sport (RS) Edition is a modern, performance-focused ATX motherboard based on the PRO series platform. It targets mainstream DIY builders who want reliable computing and gaming-capable performance without an expensive upgrade. The board combines a 14+1+1 power phase design, Dr. MOS integrated power stages, a 6-layer 2oz copper PCB and support for DDR5 XMP and AMD EXPO profiles to deliver stable power delivery and enhanced memory overclocking potential. Additional features include PCIe 5.0 support with SMT-mounted and reinforced steel slots, Nahimic audio enhancements and onboard RGB headers with Polychrome RGB synchronization.
Advantages
Integrated Dr. MOS power stages and a 14+1+1 power phase layout provide smooth, efficient CPU power delivery with improved thermal characteristics and better overclocking headroom. The 6-layer 2oz copper PCB improves signal integrity and energy efficiency for memory overclocking, while a DDR5 protection circuit reduces the risk of damaging modules during installation or removal. PCIe 5.0 SMT slots and reinforced steel retention enhance high-speed signal stability and mechanical support for heavy graphics cards. Nahimic audio processing delivers clearer voice communication and surround features across multiple output types, and Polychrome RGB headers allow synchronized lighting with compatible accessories.
Key specifications
Power design: 14+1+1 power phases with Dr. MOS integrated power stages
PCB: 6-layer board with 2oz copper inner layers
Memory: DDR5 with XMP (Intel) and EXPO (AMD) profile support; onboard DDR5 protection circuit
PCI Express: PCIe 5.0 support with SMT-type slot and reinforced steel slot
Audio: Nahimic audio engine with noise suppression, echo cancellation, voice stabilizer and Sound Tracker
RGB: Onboard RGB and addressable RGB headers; Polychrome RGB Sync support
How to use
Install the motherboard into a compatible ATX chassis and connect the CPU, DDR5 memory modules that support Intel XMP or AMD EXPO if you plan to enable pre-tested overclocking profiles, GPU into the PCIe 5.0 slot, and power supply cables to the 24-pin and CPU power headers. Attach storage devices, cooling and front-panel connectors as required. Use the BIOS/UEFI to enable XMP/EXPO profiles, configure power and fan settings, and adjust overclocking parameters. Install the Nahimic audio drivers and Polychrome RGB software in your operating system to access audio enhancement and RGB synchronization features.
Recommendations
Use high-quality, compatible DDR5 memory modules rated for XMP or EXPO and ensure the system is powered off and unplugged before installing or removing DDR5 DIMMs to reduce the risk of damage. For heavy graphics cards, use the reinforced steel PCIe slot and secure the card to the chassis for added mechanical support. Keep BIOS and drivers up to date for best stability and compatibility.
