Cool, you have the overclockers ECS board. That makes life easier. You should be able to meet your target if you got a decent CPU.
Disclaimer
1) Results will vary depending on your cooling and particular CPU.
2) Check for UPDATED bios. The early bios for that board was missing important overclocker settings!
The board allows wide adjustment of overclcoking features. This review shows the HTT (AMD 64 equivalent of FSB) can be pushed and the MB allows independent RAM control.

Also the MB has a piggy back BIOS chip that can restore a trashed bios if the overclocking goes poorly. (Been there...)
Start with the stock multiplier and push the HTT to 210. Run sisoft sandra CPU and memory burn in and make sure the temps stay pretty flat over 20 minutes of burn in.
Next up the HTT to 220 same process.
Above 210 you may need to increase the Vcore on the CPU. Again small steps, burn in and watch the temperatures. upping Vcore can drive up the temps fast.
When you hit a limit (temperature or stability) back it off 5-10 mhz and retry for stability.
You can also push the RAM. Ideally you'd like the RAM clock and HTT to be an even multiple. You get better performance when they are synchronized.
Relax the ram timings to get higher clock speeds to match the CPU HTT if possible.
Basic tool set:
cpuZ
Sisoft Sandra lite
power now dashboard (AMD oveclock monitor)
ATItool (if you have an ATI video card)
Let me know how this goes. The one thing I miss since buying ECS boards is overclocking flexibility.
