Dual Xeon Platform
Powered by dual 5th Gen Intel® Xeon® Scalable processors, the IW-RG658 PRO supports up to 32 DDR5 ECC DIMM slots, providing a maximum of 8TB system memory, enabling large-scale AI models and data-intensive applications. PCIe Gen5 connectivity ensures high-bandwidth communication between CPUs and GPUs.
High Density GPU Architecture
The IW-RG658 PRO features 16 FHFL PCIe slots supporting up to 8 dual-slot GPUs. Optimized internal spacing and reinforced GPU brackets ensure structural stability for large-scale multi-GPU deployments. Designed for AI clusters, deep learning, and GPU-accelerated computing.
PCIe Gen5 Connectivity
A dedicated PCIe Gen5 convert board provides high-bandwidth connectivity between GPUs and the motherboard. The MCIO (8i) architecture ensures stable signal transmission while simplifying system integration with pre-routed connections. This design enables scalable GPU expansion while maintaining the bandwidth required for modern AI accelerators.
Dual-Chamber Thermal Design
The IW-RG658 PRO adopts a dual-layer airflow architecture that separates GPU cooling from system cooling. The upper chamber focuses on GPU airflow, while the lower chamber maintains stable cooling for CPU, memory, and system components. A dedicated airflow duct between the two layers improves thermal efficiency and reduces heat interference between system zones.
Advanced Cooling System
To support dense GPU deployments, the chassis integrates a powerful airflow system.
• 10 front PWM fans dedicated to GPU cooling
• 4 rear fans for CPU and system airflow
With fan speeds up to 17,000 RPM, the system maintains stable operation under heavy AI and HPC workloads.
• 10 front PWM fans dedicated to GPU cooling
• 4 rear fans for CPU and system airflow
With fan speeds up to 17,000 RPM, the system maintains stable operation under heavy AI and HPC workloads.
Smart Fan Control
The IW-RG658 PRO features dedicated fan boards to manage both GPU and system cooling modules. Two front fan boards control the 10 GPU cooling fans, while a rear fan board manages the 4 system fans for the lower chamber. Integrated thermal sensors automatically adjust fan speeds to optimize cooling performance under varying workloads.
