My recommendation:
start out at default. Get your system up and running 100% stable on the basics. Get all your drivers in place and work out the bugs first. Give your system time to get friendly. You'll blame IRQ or software conflicts on your overclocking if you don't. Your fault.
Benchmark your system at default. This will give you something to compare to. If your alterations later decrease your benches then you'll know you maybe did something wrong.
Leave the fsb alone for now. focus on multiplier overclock first. Work up in steps. Yours is a 750 so after a while try 8.5x multiplier. Bench and stress your system at this setting then proceed. What to bench with? Go get Sandra, Quake3, cpustability, 3dmark, and??? Example: 3d mark helped me identify a bios problem and tests driver stability.
You should hit 950 no problem. If your memory and system tolerates a fsb increase then you should get over 1,000. 9.5 (np) or 10 mulitplier (if your lucky) times a 103 or 105 fsb will get you 978 to 1050. If fsb changes don't boot then try changing your memory setings. Many guys get stable with 3,2,2 settings or 3,3,3; you'll have to experiment.
You'll need to up the voltage to the cpu for stabilty at higher speeds. I get 900 stable at 1.7v and 950+ at 1.85v. I might get 1,000mhz with 1.9v with a mobo mod.
Watch your temp. and don't get caught speeding! GL.
