How to overclock using 'nVidia control panel'?

[Jango]

I am new to overclocking, and I wish to overclock my CPU from 2.33GHz to 2.66GHz. (Which I hope will stop the continuos freezing I keep encountering on COD Black Ops multiplayer).

I downloaded a program called 'nTune' for my nVidia control panel to do this.

I click on 'Adjust motherboard settings' and move the 'Reference clock (FSB)' slider from 333MHz, to 337MHz (the smallest increment I can do). I then click on 'Apply' and my PC freezes. I left it for 5 minutes and it remained frozen.

I would greatly appreciate any help. Thank you for reading.

Thanks guys.

I take it that the main motivation for this modest OC is that you have realised that your current CPU, if your Sig is up to date, is under the min specified for the game. ( Intel based machines = E6600) Hence a possible cause for the freezing?

Take snaggster's advice to tweak it up a little

Yeah exactly, on Black Ops singleplayer it generally works fine (completed it with only one or two freezes). But on multiplayer however, it frequently freezes.

If you want such a small increase it may even be possable to just increase your fsb in the bios without adjusting anything else.

How exactly do I do this? Because there doesn't appear to be an option to change the FSB frequency; there's only an option to change the FSB multiplier.
