Use  that is safe, for your PCI-E. setting it @ 100 keeps your MB from over volting when in Auto.
The Q8300 Yorkfield is not a bad chip, it is all FSB overclocking and your G41 with a Gigabyte motherboard is fine, no two chips will clock the same, and no two motherboards will either.
You should be able to get 3600MHz on the Q8300 @ 1.2875V 1066 or 1333 ram would be best but try these settings. Good Luck.
CPU Voltage = 1.2875V which is default VID for Rev. RO
Load Line Calibration = Disabled
C1E Support = Disabled
Intel Speed Step = Disabled
FSB Frequency = 480 X 7.5
NB Voltage = 1.41V
CPU PLL Voltage = 1.56V
FSB Termination Voltage = 1.26V
FSB Strap to NB = 333
All other settings on Auto
F10 and Save see if she boots windows.
For a good read with lots of information go online and check out, "C2D Overclocking Guide for beginners-Home-Clunk.Org.UK" clunk is one of the best and one of the craziest when it comes to C2 or P4 chipsets,
if you see a monkey sticking a fork in a wall outlet, that's his thread. Spend some time reading ALL his guides. And you will have a vary good grasp on every aspect of overclocking any 775 socket processor. Enjoy
