I am new to all this overclocking business yet I can not find anyone who can help me or an article that actually makes sense for me to read and understand. Its current clock has been set back to 1.9GHZ yet one article stated they clocked it to 2.6GHZ. I don't want to go silly with it but I am wanting something like 2.2 GHZ but have only adjusted the FSB to 166 to make it up to 1.98 GHZ. What else can I alter to clock it up to 2.2GHZ? I have read about using multipliers but am unsure of what needs multiplying.
Any help would be appreciated.

General overclocking guidelines:
Highest FSB with the lowest multiplier.

Only the FSB should be changed really. On the new Nforce 2 motherboards you get a multiplier option. 180 FSB may work on PC2700, really depends on what make of RAM it is and whether it gets too hot. You might find that 180 may work, or you may find that 175 is the max. If you cant change the multiplier than at 180 FSB the highest will be 2160mhz, then different FSBs will do different speeds so use FSBx12 to get the projected CPU speed.
The voltage levels would normally be changed in high overclocks. Really its best to leave it as it is, unless your really certain you no what its doing, as a wrong setting could blow the motherboard etc.

Thats my Motherboard. I have the 333 version.

Which ones would I need to change and would 180 work with PC 2700 RAM?

Cheers for the reply man, it does make sense and I wasn't aware about the future potential of the Athlon 64. Having just grabbed a tip top graphics card (coupled with my 1GB of RAM) I would be happy to just clock it to 2.2GHZ with a couple more chassis fans and a new case. Last time I froze my bios and I would want to do it again without a guide on how to unlock it.
Do you think it would be possible with PC 2700 RAM to clock it a 180 and use a multiplier? I will checked my bios and post the available cloking options for the CPU.

2.6 GHz is impossible with a Barton core Athlon. With a top of the range cooling kit, and the perfect Thoroughbred B core chip (a 1700XP to be precise) it might be possible. So in other words, unless you are an absolute pro, then it is out of the question. 2.2/2.3 GHz however is doable with decent air cooling.
If you only have PC2700 RAM then don't expect more than 180 MHz FSB. Not sure about your motherboard, but lots only go as high as a 12 or 12.5 multiplier, with 13 actually taking it "round the clock" as it were, starting again at 5. It is worth giving it a shot though.
A 12x 180 would still give you 2160 MHz which is pretty good. It all depends on your RAM though, some stuff overclocks well, some doesn't.
Athlon 64's aren't worth the money. They are good chips, and they do have OCing potential, but they use the Socket 754, which will be obsolete by next year, making further upgrades impossible.
Most games are far more heavily dependant on the graphics card than the processor so I don't know if it would actually be worth upgrading the processor at all.
If you are happy to just leave it be just now, or overclock a bit, then you could investigate an upgrade in a year or two.
If you really are desperate to upgrade now then go for a P4. On the 1st of February the P4s will get a 15-20% price cut across the board as on the 2nd the new P4 core, called Prescott, will be released. Prescott uses a new socket so has much better potential for the future.
Like the Athlon, the current P4 (called Northwood) has reached the end of its life basically. Thats why I won't upgrade for a year or two. An Athlon 3000XP is plenty for a year or two.
Hope I didn't get too technical.

Cheers for the reply.
My motherboard is a KT4 Ultra which is a decent motherboard but it doesn't really allow for massive overclocks. I froze my Bios last time I overclocked my FSB to 200 and the RAM went strange as well and I kept getting Windows Protection errors. I don't think I will bother then, I had planned to get an Ahtlon 64 but was hoping I could maybe tweak a few thinga in the mean time.

What motherboard do you have? If its a Nforce 2 like the Abit NF7-S then its easy.
2 things make up the clock speed, the first is the FSB which is 166 on your CPU. The other is the multiplier which I think is the number of cycles per second. So with yours its 12x166 then which equals 1992 mhz. Depending on the RAM you have then you could put up the FSB to 200 and lower the multiplier to 11 and get 11x200 which is 2200 mhz. But to get the best performance you need to keep the RAM running the same speed as the CPU. So if the RAM can only overclock to 180mhz FSB then keep the CPU the same. From another post it seems you have PC2700 RAM, which would mean you can run 166 but may not run anymore depending on how it overclocks. Most motherboards should actually by default keep the RAM and CPU insync. So if you cant get higher FSB then up the limiter so to get 2.2Ghz you could do a 11x200, 11.5x192, 12x183, 12.5x176, 13x169. Keeping the RAM at 166 you could go for 13.5x166 which would be 2.242 Ghz. If you have noticed the multipliers are always whole or have .5.
You also need to be wary of heat. Make sure your case has decent airflow and you have a good heatsink on your CPU. Remember that RAM can be overclocked but some overclock better, and be careful of heat build up on the RAM. If you want to overclock the CPU then maybe get some decent PC3200 RAM so you can push the FSB right up to 200mhz without overclocking the current RAM.
