Im not sure on settings as my Asus(i think) P4S800-MX board did all the work for me and allowed me to choose 2.4 or 3.6ghz but iv'e been running it for almost a month now i think at 3.6ghz on stock cooling etc and it is great
I don't think any of the celeron line support HT and probably won't or atleast for some time. Im also using Kingston Ram(256mb Single Sided Module) which is rated at DDR400 PC3200.
