| Product Description |
|---|
This motherboard is built for Lenovo's SR635 and SR655 server models, providing a reliable foundation for enterprise workloads. It often appears in data centers or business environments where flexibility in security options is needed, as it lacks a TPM module. Ideal for system builders and IT professionals who require high computing power, it supports AMD EPYC CPUs and offers various expansion slots for network cards or storage controllers. The absence of TPM makes it suitable for setups that manage security externally or do not require hardware-based encryption. Key Features
This motherboard is typically deployed in server racks within corporate data centers or research institutions where customizable hardware security is a priority. It plays a key role in enabling versatile server configurations without limiting performance. |
