In the manual for my mobo it says it can support an FSB of (1333) 333MHz as the E7300 has currently an FSB of 266MHz Id therefore like to increase it to 333MHz which would get me up to 3.33GHZ which Id be happy with
My BIOS currently reads:
Intel EIST: (Enabled)
Adjust CPU FSB frequency MHz: 
DRAM TIMING mode: (Auto)
1N/2N memory Timing: (Auto)
FSB/DRAM Ratio: (Auto)
Adjust PCI-E Frequency MHz: 
Auto disable DRAM/PCI Frequency: (Enabled)
Spread Spectrum: (Enabled)
There doesn't appear to be a section on voltages? Ive had a look around the various menus
Can I just adjust the CPU FSB Frequency to  or do I need to change any of the other settings? Ram settings? Is it a problem that I can't adjust the voltage to the cpu if so could Increase the FSB to say  without adjusting any voltage for a mild overclock
Thanks in advance for any help Im new to this. I hope ive provided enough information
Try reading our basic overclocking guide. It will help you a lot.
If you cannot change voltages then that motherboard probably isn't very good to overclock but we'll see what we can do for you.
Since you cannot change the voltage then you're limited to whatever's stable at stock voltage. You can try guessing or simply raise it slowly until it's at the limit. Also don't forget to change the FSB/DRAM ratio to manual so that it doesn't exceed your RAM speed
Both of these guides are good for background, but not actual BIOS settings.
Next stop should be a guide for your particular motherboard or a similar MSI Core2 board. Google is your friend.
You will have at least two problems. First, the G41 has limited OC capabilities. Still both the motherboard and the CPU should run with a 333 MHz FSB freq.
Your second problem is your RAM. It is DDR3-1066 RAM with means that it is rated for a 266 MHz FSB freq (no overclock headroom ). You may be able to extend the operating freq by running it at 1.65 volts (that is safe for a Core2 CPU) and relaxing the timing to something like 8-8-8-24.
Assuming that you have access to some of the BIOS settings, take your memory settings off Auto and do whatever you need to adjust the mem clock to 1066 MHz.
MSI may have provisions to set the FSB:RAM ratio. If so, set it to 1:1.
Now start increasing the FSB freq and voltage (if you can) to maintain stability.
Most G41 boards have an FSB limit around 340 - 360 MHz.
Do not exceed core voltage of 1.45 volts or load temps of 70 C.
