To find the CPU's max you need to lower the Ram speed well below spec to make sure it's not the limiting factor in the overclock (ie causing instability).
Once the CPUs max has been found, bring the Ram speed back up to normal running speed and then try to increase this as much as possible without causing instability.
You can also try increasing the latency of the Ram to see if this gets you a faster overall speed on your ram, but in general having tight timings on an A64 yields the best results.

So if i lower my timings to 2.2.2.5 @ 200MHz what do I do to check my max CPU speed with regards to my FSB and multiplier ?

Thanks for the help by the by.

You want to increase your timings really (3-3-3-8) and use another divider Eg. 100. Then raise the HTT until the PC can't boot, then up the vcore to the next notch and keep doing this until you can't get any further. Prob best not to raise the vcore above 1.65v, but keep as low as possible, and always ensure your temps don't go above 50-55C max. When you can run OCCT (30 mins) or Prime95 for 8+ hours you know that your CPU is stable. If it's unstable, back your HTT down slightly or raise vcore, as appropriate.

Err, whats 'HTT' ?

Sorry for being such a n00b here, being building my own comps for a while just never overclocked before.

That's what you increase to increase the CPU's and Ram's speed. Starts at 200Mhz and works upwards in 1Mhz intervals.

Yep, that sounds familiar. If you haven't already, change your HT Multiplier. This should be near CPU Freq and currently set at 5. This multiplied by the CPU Frequency should be kept below 1000Mhz to keep the system stable. Therefore, drop to 4 up until 250Mhz and then 3 above this value.

So what am I doing here then ?

Keep the clock speed below 1Ghz by increasing the CPU Frequency and lowering the CPU multiplier ?

Checking the Motherboard's max HTT value
