Effects of raising/Lowering PCIe bus

[Agromahdi123]

just out of curiosity what are the effects of lowering or raising the pci express bus from 100 mhz, which is what its set at currently. Does it add more bandwidth for the GPU to use? i mean what does it do exactly? thanks

Basicly it just effects the bandwidth of the PCI Express slot, but seen as graphics cards dont use anywhere near the bandwidth available, and that changing the slot speed can make your card unstable, or maybe even damage it, just leave it at 100MHz .
