Gigabyte R7 260X stuck in 1x PCI



Hi, My new GPU is underperforming because it is always in PCIe 2.0 1x mode. I tried to experiment with

drivers, etc., and the only time I was able to run it at 16x was when I installed older ATI drivers

without a Catalyst Control Center. But now with this new driver stuck in 1x even under full load. I do not

keep older drivers because they had other improvements ... Under GPU load is PCIe 2.0 1x and at the same

time idling is PCIe 1.1 1x Also Catalyst Control Center has to say about my hardware:

graphics capability Bus PCI Express 3.0 Maximum configuration Bus PCI Express 2.0 x1 Core Clock MHz in 1188

MHz Memory Clock 1625 MHz MHz in total memory bandwidth in GByte / s 104.0 GByte / s BIOS Version
