The T420 supports graphics processing unit (GPU) technology, providing accelerated performance
for a variety of applications such as VDI and medical imaging.
The T420 supports two nVidia
double-width GPU. GPU cards are available through certified factory installation (CFI) or field
upgrade only.
Each GPU supports up to 6GB of dedicated GDDR5 memory and is actively cooled. Each GPU has
one or two power connectors to meet the high demand for power delivery. The power connectors
are 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 (slot
5 requires a two-processor configuration). The interface for the next generation GPU cards will be
PCIe 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 device

Some operating systems have not been validated to support GPUs. See Table 20 for more
information on operating system support of GPUs.
The Intel C600 chipset is implemented on the PowerEdge T420. For more information, visit
