Do NOT listen to the above.
All you can do is try & see how far you can get. You're biggest problem will be your motherboard...SiS based boards are not the greatest.
I wrote this recently for someone else. I had to change it a bit to fit an Intel system:
"...you should strive to run both the CPU & RAM at the same bus speed. Since you have a locked 133MHz (533FSB) CPU & 200MHz (DDR400) RAM, you're gonna have to shoot for something in between.
Go into the BIOS & lock the AGP speed at 66MHz, change the DRAM setting from "BY SPD" to 100% (or if there's a CPU:DRAM ratio, set it to 1:1), disable all Spread Spectrum settings, then begin raising the FSB a little (3-5MHz) at a time. Reboot & test your system after every change...if the system becomes unstable, you can try adding a little voltage (0.025v at a time) to the CPU to see if you can get it to stabilize. It's all trial & error & it will take some time. Keep an eye on your temps. Once you're satisfied with your clock settings, run a couple of Stress Tests to see if your system remains stable under load. TOAST is one program you can try...Super Pi is another. Still another is Prime95, or try the newer version called Stress Prime 2004. These programs will run continuously until you stop them. Try TOAST for 30-60 mins, if there are no probs, move on to Prime...let it run for a couple of hours. If you have no problems, blue screens, lockups, overheating, etc, you should be good to go.
