Hi all.... I have never tried overclocking before and thought I might give it a try. I have an Aopen MX 46 motherboard with a P4 1.7GHz processor installed. According to Aopen this board has lots of overclocking ability but I don't really understand the translation on their website. Apparently I can change the FSB speed in the bios. I also understand that Intel processors are somehow locked, so what can I change to overclock this processor? Is an increase in the FSB speed the way to overclock this machine?
Any info including relevant websites would be appreciated.

Yes, most if not all Intel CPU's are multiplier locked.
The only way to Overclock it is to turn it's FSB up.
I'm guessing that a 100 MHz FSB cpu. So try something like 110 or 115
The best thing to do is to try turning it up only little by little.
You might be able to get 2GHz out of it depending on what kind of ram you
have.
You might be able to get better then 2 GHz out of it, but I cant tell you
that.
You have to play around with it & see what settings work the best.
Hm, CPU's that r Locked, my Xeon's can be turned down from the
20xMultiplier.

No, Intel Pentium 4 CPUs have nominal FSB's of 400, 533, 800, or, just recently 1066 MHz, not 100 MHz.
No, Intel CPU's since the Pentium II 300 MHz are multiplier locked, and no, your Xeon multiplier can't be 'turned down'. Likely you can change the multiplier setting in the BIOS, but that has NO EFFECT.

Your Pentium 4 1.7 GHz can be overclocked only by increasing the FrontSideBus speed. Unfortunately, a Pentium 4 1.7 GHz is a 'Willamette' technology CPU, and has little overclocking potential compared to its successor, the 'Northwood'. The 'Northwood' Pentium 4 CPUs are based on a faster, lower voltage, lower power technology and have a larger L2 cache. For example, a 'Northwood' Pentium 4 1.6A can fairly often be overclocked by 50%. Your Pentium 4 1.7 is much more limited.
Generally a good indication of casual overclocking ability is the highest nominal speed CPU of the technology. For the 'Willamette', that is 2.0 GHz, while for the 'Northwood' it is 3.4 GHz. You can overclock your CPU by increasing the FrontSideBus speed, but don't expect much above 2.0 GHz. In other words, go ahead and try overclocking, but don't spend any money on extra cooling, etc. for your present CPU - it just isn't worth it.
Unfortunately I don't have any overclocking links that seem to be current, but you should pretty much reach the maximum for your current CPU by just raising the clock speed (the clock speed is 1/4 the FrontSideBus speed.) Your CPU has a fixed multiplier of 17X, so raising the clock speed from 100 MHz to 120 MHz (and consequently the FrontSideBus speed to 480 MHz) will give a CPU speed of 17 X 120 MHz = 2040 MHz. You should keep several things in mind.
#1. Make sure that your PCI bus speed is not above about 37 MHz (nominal is 33 MHz.) A PCI bus speed over specifications begins to run the risk of data corruption when data is written to hard drives. If your motherboard has a FIXED setting for the PCI and AGP buses that locks the PCI bus to 33 MHz and the AGP bus to 66 MHz, use that setting for overclocking. (Usually, the PCI bus speed is 1/3 the system clock speed and the AGP bus speed is 2/3 the system clock speed, but chipsets for Pentium 4 CPUs have the ability to fix those bus speeds rather than using a divider.)
#2. Before starting to overclock your older system, make sure the system is clear of dust and other thing that might restrict the flow of cooling air. Especially make sure the CPU heatsink fins are clean. Keep an eye on the CPU temperature when trying to overclock, and compare it to the CPU temperatures when not overclocking. In overclocking, you are trading the built-in stability overhead for higher speeds. Higher temperatures result from overclocking and higher temperatures reduce overclocking ability. Try to keep the temperature rise as low as possible.
#3. Raise the system clock speed in small steps, in your case, say 5 MHz. Change nothing else. If your systems boots and starts the operating system, try putting a load on the system. If it is stable, you can try a higher system clock system. If it is not stable, you can try increasing the CPU core voltage by a small amount, say 0.05 volts ( in no case go higher than 0.15 volts above the default - it isn't justified for your CPU.) By going back and forth with these adjustmenst you will eventually find the highest stable CPU speed for your system.
Most important of all: you will not destroy your CPU or motherboard from overheating, raising the CPU core voltage too much is an instant CPU killer.
Hope this helps.

Not really the true FSB, or we would be looking @ total bus speeds of
400x4=1600
533x4=2132
800x4=3200
And 1066x4=4264
The true FSB's are really
100x4=400
133x4=533 (133.25)
200x4=800
And 266x4=1066 (266.5)
Goto http://processorfinder.intel.com/scripts/default.asp Look up any CPU, Intel them selves lists them all as just (Bus Speed)
Not FSB
If you want to correct some1 on something, then be correct about it.

up.

Not even Intel is consistent on that one!
Small wonder it should be picked up by 'RaichuRaichu' aka 'RavingRaichu' aka 'Denny' aka 'Dennis E Strusser Jr' who evidently needs change his email address often because of newsgroup email identity harvesting.

The above would only be the case if Kony had been referring to the "bus clock." But he wasn't.

Your equations for the "true FSB's" result in the same numbers Kony stated: 400, 533, 800, 1066.
They do, however, explain how the effective FSB speed is derived from quad pumping the base FSB clock. I.E. FSB clock times 4 gives effective FSB speed.
