PCI Express 2.0 x16_2 slot (x8 link)
PCI Express x1_1 slot
PCI Express 2.0 x16_1 slot (x8 or x16 link)
When PCIe 2.0 x16_2 and PCIe 2.0 x16_4 slots are occupied, PCIe 2.0
x16_1 and PCIe 2.0 x16_3 will work at x8 link.
In single VGA card mode, use first the PCIe 2.0 x16_1 slot for a PCI
Express x16 graphics card to get better performance.
We recommend you use the PCIe 2.0 x16_1, PCIe 2.0 x16_2, and PCIe
2.0 x16_3 slots for 3-way SLI, and the three slots will work at x8, x8 and
x16 link respectively; the PCIe 2.0 x16_1, PCIe 2.0 x16_3 slots for two-way
SLI, and both slots will work at x16 link.
When using NVIDIA
®
card and Tesla™ series computing processor cards, install the Quadro™
graphics card to PCIe 2.0 x16_1 slot and the Tesla™ computing processor
cards to PCIe 2.0 x16_2, PCIe 2.0 x16_3 and PCIe 2.0 x16_4 slots.
Connect a chassis fan to the motherboard connector labeled
CHA_FAN1/2/3 when using multiple graphics cards for better thermal
environment. See page 2-42 for details.
