Intel® Server 3200/3210 Chipset Speed Limitation on the PCI Express* x16 Slot for Intel® Server Boards
The Intel® Server Board S3200SH uses the Intel® 3200/3210 Chipset that has a limitation between the chipset and the PCI Express* x16 slot. There is one PCI Express* x16 connector to be used as a x16 link for the chipset. If a graphics adapter is inserted into this slot, the graphics card will only work at PCI Express* x1 speed. This is due to chipset design and has no workaround.
