GPU cards are available through certified factory installation (CFI) or fieldupgrade only.Each GPU supports up to 6GB of dedicated GDDR5 memory and is actively cooled. Each GPU hasone or two power connectors to meet the high demand for power delivery. The power connectorsare located on the back of the card.The GPUs from nVidia have PCIe 2.0 that can be installed in the T420 PCIe x16 3.0 slots 3 and 5 (slot5 requires a two-processor configuration). The interface for the next generation GPU cards will bePCIe 3.0.The following system configuration restrictions apply when a GPU is installed: 1100W redundant power supply is recommended System can support only one 5.25-inch deviceSome operating systems have not been validated to support GPUs. See Table 20 for moreinformation on operating system support of GPUs.The Intel C600 chipset is implemented on the PowerEdge T420. For more information, visitIntel.com.
