OVERVIEW
The NVIDIA®Tesla®K20 graphics processing unit (GPU) active accelerator board is a
PCI Express, dual-slot full height (4.376 inches by 10.5 inches) form factor computing
module comprising of a single GK110 GPU. The Tesla K20 active accelerator is designed
for workstations and offers a total of 5 GB of GDDR5 on-board memory and supports
PCI Express Gen2.
The Tesla K20 can be configured by the OEM or by the end user to enable or disable
ECC that can fix single-bit errors and detect double-bit errors. Enabling ECC will cause
some of the memory to be used for the ECC bits, so the user available memory will
decrease by 10%. On the Tesla K20, the register files, cache, and DRAM are ECC
protected.

POWER CONNECTORS
The Tesla K20 GPU active accelerator board supports two 6-pin PCI Express power
connectors on the "east end" of the board.
Auxiliary 6-Pin PCI Express Power Connector
The Tesla K20 GPU active accelerator board is a high powered board solution and it
utilizes power from the PCI Express connector as well as the external power (a single 6-
pin PCI Express power connector is required for the Tesla K20). Figure 4 shows the
specification, and Table 5 shows the pinouts for the 6-pin external PCI Express power
connector.
