You dont need to change pci-e you should leave it at auto or 100 mhz, it shouldn't be increased as it can damage your graphic card.
You should change cpu host frequency, for your cpu you need to put it to 429 to get it to run at 3ghz, since your cpu has low multiplier, but it may be too much. Try 400 mhz for starters and see if that is stable.
Also make sure to change memory multiplier so it doesnt run at more then 800 mhz, or that can also cause instability
