I have never used that motherboard but a quick search and looks like your best bet are Northwood core P4. Some motherboards did not like the hyper threaded variants and I cant find any reference online of anyone using one. Though saying that if you shop about you can normally grab them cheap so it may be worth just grabbing one and trying. I also dont see anyone running quicker than 2.8GHz chips. They did do a Northwood HT on a 533FSB at 3.06GHz that may possibly work though my gut is skeptical. I have in passed grabbed engineering sample chips with unlocked multipliers that may be wroth grabbing if you see one cheap but again no guarantee it will work as it should or at all with your motherboard. Sorry not much help.

I tried a faster Northwood like a 3,2Ghz with 512kbyte L2 but it's strange it boot as 1,6ghz and the FSB can't go above 133Mhz. But with the 2,8Ghz I could set in the bios up to 166Mhz. Why?
