PCI Express

[daniel0720]

I fellowed the steps of the user guide of xapp 1052 and programmed the routed.bit into FPGA, then I installed the corresponding driver, but in device manager, the driver was in other device column, as depicted the below pciture. The application still work, but the bandwidth was 1.5~1.7GB/s, the system motherboard is Intel X58.

Is this a serious problem? How to solve it?

Thanks in advance.

How many lanes are you using? Also, is this a gen1 or gen2?
