OVERVIEW
The NVIDIA GRID™ K2 is a dual-slot 10.5 inch PCI Express Gen3 graphics card with two
high-end NVIDIA® Kepler™ graphics processing units (GPUs). The NVIDIA GRID K2
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.
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.

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.

Notes:
*Bellcore Code GB relates to non-mobile equipment used in ideal environment (lab, medical, and test
equipment).
**Bellcore Code GF relates to non-mobile equipment used in less than ideal environments (rack mount or
other instrumentation or equipment used in buildings without controlled temperatures).
