This is the only thing that I found out, I didn't find any solution to your problem, but this is the cause.

It uses Speedstep, a laptop (mobile) technology, the multiplier on all models starts the processor in the low power state, which is multiplier x12. When signalled by GHI and DPSLP, it switches to the x23 multiplier (133MHz x 23 = 3.06GHz).

So, without speedstep support the CPU will operate at the low-power speedstep settings.

ya I found that out as well, apparently not all p4 3.06 processors are created equal. I happened to pick the one that did not support hyperthreading and could not have it's speed step recognized by my mb. So I'm re-selling the thing on ebay and cutting my losses. Ironicly I did find a site that does sell the regular p4 3.06 cpu by accident while researching my problem, it costs about the same price that I had paid for this one...........lovely..............
