I don't see anything on their website about support for Tualatin processors or Intel VRM 8.5-you need VRM 8.5 to support Tualatins, which run at 1.475v. Are you sure you even have a Tualatin?
I ordered a Celeron 1 GHz (not tualatin), but i think i got something else, Because the celeron i got has 256 Kb Cache and is a 0,13 micron processor.
So I started to think that they have send me the wrong processor...
All the new socket370 processors say FC-PGA2 on the box and have heat spreaders, BUT you can tell the difference in the voltage: If it's 1.75v, it's a Coppermine, compatable with older boards. If it's 1.475v, it's a Tualatin, only compatable with the latest boards.
You have get a CPU with Tualatin core(13 micron and 256 Kb cache). It will not work with older board. You need a CPU with Coppermine (18 micron and 128 Kb cache) core.
