OVERVIEW
The NVIDIA® Tesla® K10 graphics processing unit (GPU) accelerator is a PCI Express,
dual-slot, full height (4.376 inches by 10.5 inches by 1.52 inches) form factor computing
module comprising two NVIDIA GK104 GPUs. The Tesla K10 offers a total of 8 GB of
GDDR5 on-board memory (4 GB per GPU) and supports PCI Express Gen3.
The Tesla K10 can be configured by the OEM or by the end user to enable or disable
ECC or error correcting codes 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 K10 the ECC protection is for
DRAM only.

Note: The Tesla K10 can be installed and works in a PCI Express Gen2 system as
well. In such configurations the Tesla K10 will run at PCI Express Gen2 speeds.

STANDARD I/O CONNECTOR PLACEMENT
As shown in Figure 3, the Tesla K10 includes a vented bracket. If you are an OEM who
qualifies for bracket modifications, you have the option of receiving your modules with
no bracket installed.

Mechanical Specifications
If you need to remove the standard bracket follow these simple steps:
1.
Remove the two shoulder screws on the back side of the PCB.
2.
Remove the two flat head screws on the bracket exhaust face.
3.
Remove the bracket.
4.
Slide the washer in between the PCB and the backplate to maintain clearance
between the PCB and the backplate.
5.
Attach the shoulder screws.

INTERNAL CONNECTORS AND HEADERS
The Tesla K10 GPU accelerator supports the following internal connectors and headers.
 8-pin PCI Express power connector (can be used with a 6-pin power cable)
 6-pin PCI Express power connector
External PCI Express Power Connectors
The Tesla K10 GPU accelerator is a performance optimized, high-end product and uses
power from the PCI Express connector as well as external power connectors. The board
can be used in two different ways.
 One 8-pin PCI Express power connector or
 Two 6-pin PCI Express power connectors
Figure 6 and Figure 7 show the specifications and Table 2 and Table 3 show the pinouts
for the 6-pin and 8-pin PCI Express power connectors.
