Dell 7KMJ7 PCI-E X16 Dual CPU Riser Card Board for PowerEdge R420

Product Description

The Dell 7KMJ7 is a specialized riser card designed exclusively for the Dell PowerEdge R420 rackmount server. Its primary function is to provide the necessary physical connections and electrical pathways to support a dual-processor (dual CPU) configuration within the server's chassis. In many compact server designs like the R420, the main motherboard may only accommodate a single CPU socket, or the riser card is used to position the CPUs and associated expansion slots in a way that optimizes space and airflow. This riser board features a PCI-E x16 slot, which is typically used for high-bandwidth expansion cards such as graphics cards or high-speed network adapters. However, in the context of the R420, its main purpose is to host the CPU sockets and potentially other essential components required for a dual-socket setup. It connects to the server's main system board via a proprietary connector, allowing the two CPUs to communicate with the rest of the system. For users looking to upgrade their Dell PowerEdge R420 from a single-CPU configuration to a dual-CPU setup, or for replacing a faulty riser card, the 7KMJ7 is an essential component. It ensures that the server can properly recognize, power, and utilize two processors, thereby doubling the potential processing power and enhancing its capability for demanding workloads like virtualization, database operations, or application serving.
