All CPUs are different so you cant just "copy" someone else's overclock straight out. Winchesters are not the best overclockers out there but 2.4GHz should be pretty doable (hopefully, heh).
That said I'll give you some settings that I'd try. If they work for you, great, if not then I'd suggest you tinker with your system yourself.
Since I'm not familiar with your mobo I cant say much about it other than it being based on a VIA chipset (k8t800 pro or k8t890, hopefully). So hopefully you'll have fully pcie(agp)/pci locks.
First off, diasable Cool and Quiet.
Then,
HTT (Or CPU) Clock Frequency: 240
Hypertransport Speed/Multiplier (or Frequency, the HT link may also be called LDT, which is the proper name): 800MHz or 4x, whichever option you get.
DRAM Speed/Frequency(this is the ram "divider" setting): Either 333 or 166, it could be writen either way, but you'll only have one of the two options.
About the voltages:
First I'd try everything at stock, if it doesn work then try the following,
Vcore/VID/CPU Voltage ID (or whatever your motherboard calls it): 1.5v, you may also have a percentage-based CPU voltage control, you can use either one but remember that both work simultaneously. If your CPU does not work properly at this voltage you can go higher still, but I wouldnt recommend going over 1.55v on the stock cooler, even that might be cutting it close. If voltage works fine the first time you bump it up then try lowering it. Remember that the lower the voltage, the better.
VDimm/DRAM voltage/Etc: Raise this to 2.8v if the VCore doesnt help, though I dont think this will be really needed. By the way, having Command per Clock enabled (or Command rate set at 1T) will give you a decent performance boost, if your system can take it.
