OVERVIEW
The NVIDIA® Tesla™M20-Series graphics processing unit (GPU) Computing Module is a
PCI Express, double-wide, full-height (4.376 inches by 9.75 inches by 1.52 inches) form
factor computing module based on the NVIDIA Fermi GPU. This module comprises a
computing subsystem wit h a GPU and high speed memory.
This module is offered with two memory sizes:
The Tesla M2050 module offers 3 GB of GDDR5 memory on board.
The Tesla M2070 and Tesla M2070Q module offers 6 GB of GDDR5 memory on
board.
Both of these products 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 report 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 to approximately 2.62 GB for a Tesla M2050 and
approximately 5.25 GB for a Tesla M2070 and Tesla M2070Q.
The Tesla M2070Q GPU computing module uses the NVIDIA Fermi GPU that combines
Tesla’s high performance computing and the NVIDIA Quadro®professional-class
advanced visualization in the same GPU. Tesla M2070Q is the ideal solution for
customers, who want to deploy high performance computing, advanced and remote
visualization in a datacenter.

STANDARD I/O CONNECTOR PLACEMENT
As shown in Figure 3, the Tesla M2050 and Tesla M2070/M2070Q include 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.
