The overclock (3.60GHz) passes CPU stress tests perfectly. There is only one problem, while overclocking the CPU, the GPU only runs in 1x mode.
CPU host Frequency: 400
PCI-e frequency: 100
SPD: 2.00
Cpu voltage 1.2-1.32v tested

I don't know what to do, any help with this problem will be appreciated.
