OVERVIEW
The NVIDIA GRID™ K2 is a dual-slot 10.5 inch PCI Express Gen3 graphics card with two
®
high-end NVIDIA
has 8 GB of GDDR5 memory (4 GB per GPU), and a 225 W maximum power limit. The
NVIDIA GRID K2 graphics board uses a passive heat sink that requires system airflow
to properly operate the card within thermal limits. It is designed to accelerate graphics
in virtual remote workstation and virtual desktop environments.
Kepler™ graphics processing units (GPUs). The NVIDIA GRID K2
The NVIDIA GRID K2 graphics board can be configured to enable or disable ECC (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%. ECC protection is for DRAM only.

Mechanical Specifications
If you need to remove the standard bracket follow these 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.

POWER CONNECTORS
The NVIDIA GRID K2 board utilizes power from both the PCI Express connector and
the auxiliary power connectors. The NVIDIA GRID K2 board supports the following
internal connectors:
One 6-pin PCI Express power connector
One 8-pin PCI Express power connector
Figure 6 and Figure 7 shows the specifications and Table 2 and Table 3 show the pinouts
for the 6-pin and 8-pin PCI Express power connectors, respectively.

Power Connectors
POWER SPECIFICATIONS
The NVIDIA GRID K2 board utilizes power from the PCI Express connector as well as
one or two auxiliary power connectors. Table 4 lists the supported configurations
Table 4. Configurations with External PCI Express Connectors
Connector Type 6-Pin Power Connector Supported Notes
8-pin connected 6-pin connected Yes
8-pin connected No cable installed Yes 8-pin cable must supply 150 W
6-pin connected N/A No 6-pin cable in the 8-pin
connector is not supported.
Not installed N/A No 8-pin connector should always
be connected.
Note: If the auxiliary power cables are connected in an unsupported configuration, the NVIDIA GRID K2
board will power up in a low performance mode. The software will de t e ct and re p ort the incorrect
power connections so actions can be taken by th e user to resolve.
Note: The power breakdown per input rail is available to authorized system
partners in the NVIDIA GRID K2 System Design Guide (DG-06546-001).

THERMAL SPECIFICATIONS
The NVIDIA GRID K2 graphics board uses passive heat sinks that require system
airflow to properly operate the card within thermal limits. Table 5 provides thermal
information necessary to deliver reliable operation of the NVIDIA GRID K2 GPU. This
information is not intended to provide a specific thermal management solution.
For more detailed information regarding thermal specifications for the NVIDIA GRID
K2 board, refer to the NVIDIA GRID K2 System Design Guide (DG-06546-001).

RELIABILITY
The mean time between failure (MTBF) ratings for the NVIDIA GRID K2 are tabulated
in Table 6. The calculation of these values uses the Bellcore’s Parts Count method in
controlled environments.
Table 6. Mean Time Between Failure (MTBF)
Condition (Bellcore Code) MTBF
Ground Benign (GB) environment, 35 °C * 232,528 hours
Ground Fixed (GF) environment, 35 °C ** 127,664 hours
Notes:
*Bellcore Code GB relates to non-mobile equ ipment used in ideal en v ir on m e n t (lab, medical, an d t est
equipment).
**Bellcore Code GF relates to non-mobile equipment used in less t h an ideal environment s ( rack mou n t or
other instrumentation or equipment used in buildings without controlled temperatures).
