Revolutionary PCI Express interface provides scalable bandwidth for multi-purpose usage. PCI-E x16 interface (The GA-M61VME-S2 supports up to PCI Express x1 mode, please refer to the VGA cards support list) doubles the bandwidth of graphics interface of previous generation thus delivering the utmost gaming experience. PCI-E x1interface provides twice the bandwidth of PCI interface up to 250MB/s for new generation I/O peripheral devices.
My motherboard has a PCI-E x 16 interface but supports up to PCI Express x1 mode.
What is the meaning of this?
