I realize that this system is probably pretty old but any help would be appreciated. First off, let me say that I am clueless on how to do the overclocking thing. Any information on how to overclock my P3 733 processor on my asus cuv4x motherboard would be appreciated.

The motherboard? Garbage. The CPU? Already at 133FSB, how far do you think you can push the rest of the components? Verdict? Resell.

Your ability to overclock is going to be directly related to your memory speed and memory timings. If you have pc133 memory at a cas 2.0 timing, you can probably over clock. You need to go to the BIOS setup. Press the del key to enter the BIOS setup. Browse the BIOS to find the clock frequency of your processor. You will have to change the front side bus in order to over clock the processor. You may also have to change the voltage to overclock the processor. Your memory timings may have to be put at 3 cas latency to overclock. This is just a start because your addon cards may not like the increase in frequency. When you bump up the front side bus your addon cards frequency also increase by the same percentage. Heat is another concern. You may have to attach a larger fan and heatsink to your processor to get the desired overclock/stability features.
Hope this helps,
Todd

With the Award Bios can you step the FSB from 100 to 133, or is it a sudden jump? I dont think my p3 750 will make 998@133, but perhaps something slightly lower, 825@110 would be good.

If all else fails, Go further :)

No, but it might make 1000 at 133, you see, "33" speeds are actually calculated at 1/3 of 100, as in 133.33 continuous. Early steppings of the 750 would do 1000 with about 50% success, later steppings had better success. So with a minimal chance of 50%, you should try it.

Your bus speeds available are 66, 68, 75, 80, 85, 90, 95, 100, 103, 105, 110, 112, 115, 116, 118, 120, 124, 126, 130, 133, 135, 138, 140, 142, 144, 146, 148, 150, 155, 160, 166. Anything between roughly 120 and 133 are hard to accomplish on most boards do to the PCI bus being overclocked-at 133, you get a 1/4 PCI divider, at lower speeds you get 1/3, and PCI should be around 33MHz.

You will probably need between 1.85v and 1.95v to get your 750 to 1000. Remember that your performance will be as much as 10% lower than with a BX chipset, at any speed. Keep an eye on temps, not for fear of damage (won't happen), but because the Coppermine becomes unstable usually between 55C and 60C.
