cant you lock it at 33.33mhz??

PCIE freq at 100mhz, by default PCI clock will be at 33.33mhz. so either way, it's not a prob. unless u increase ur PCIE freq.

probably. when u lock pcie freq, the pci clock should be locked depend on ur pcie freq. if u put pcie freq on auto. it'll increase when u raise ur fsb bus thus also increasing ur pci clock which is not a good thing. set it to 100mhz is good enough.

running above 110mhz for pcie freq is not recommended as it can probably kill ur GPU and probably ur sata hdd.

if i'm wrong, can someone bash correct me,i'm still learning though~

PCIe is connected to the SATA on most mobo. anything higher than 105mhz can lead to data corruption on ur sata hdd.

too high pcie freq, sata controller wont work. also depend on mobo and at which freq it wont work.
