Nvidia Quadro - Manual (Page 2)

Requirements:
- Any two NVIDIA Quadro PCI Express graphics boards: NVIDIA Quadro FX 4400, 3400, 1400,
1300, 540, 330
Motherboard and Power Supply Requirements
To support SLI, your PC motherboard must be PCI Express-based, with two available and
adjacent PCI Express expansion slots. Both slots must be x16 mechanical with the following
allowed electrical slots:
x16 + x16
x16 + x8
x16 + x4
Since SLI supports up to two high-end graphics boards, the load on the system’s power supply
can increase significantly. A minimum of a 450W Power Supply Unit (PSU) is recommended. An
inadequate power supply will result in erratic and unpredictable system behavior.
SLI Hardware Installation
Figure 1. below shows an SLI-capable NVIDIA Quadro FX 1400 professional graphics board
along with SLI Hardware Bridge Connector. The NVIDIA Quadro FX 3400 and 4400 also support
SLI and require an auxiliary power connector cable, which is also shown. Please remember the
following:
- SLI is supported only on PCI Express-based motherboards
- Two available and adjacent PCI Express expansion slots are required, one must be x16, the
second slot can be x16, x8, or x4
- Some SLI capable graphics boards require an external power cable (FX 3400, FX 4400) make
sure that these cables are properly connected to ensure reliable system operation
- An SLI bridge connector (provided with your graphics board) must be installed to utilize the full
capabilities of SLI Frame Rendering
