I have Win 2k here (MSDNAA rules), you think it is worth running tests in a VM?
That would be cool, if it's not too much effort. I wasn't aware that there's a SSE2 problem with W2k, but this doesn't look like a coincidence at all.

I had a system where SSE (not SSE2) wasn't showing up even though the CPU had it. I even swapped out the CPU for another one that I KNEW had SSE and the system still didn't recognize it. Finally had to replace the MB for E@H and SETI to use it. It was an XP PRO system.
Willamette didn't have Hyperthreading, and neither did Northwood until the 3.06GHz model.

It is not reported on my sons, P4 2.0 GHz Willametta skt 423. But is on his friends P4 2.53GHz Northwood skt 478. Both are non-HT. And although both machines have moved away, I am prepared to believe what they say as they are both BSc Computer science grads.

It's possible that there is some errata, or perhaps engineering samples or whatnot, but the PDF I pointed you to is from Intel. IOW, from the source... The PDF is located on Intel's servers and is an official Intel document.
Also, take a look at this image:
I know that is for an AMD system, but it is possible that one of the two systems you had also had BIOS "killswitch" capability for extended CPU functions.
Sorry, but I have to disagree with you on your assertion...
OK, I'm one of those dial-up folks. Why do I get over 80 CPU hours of work from a download. That's unreasonable given the deadline that's being set
Even the longest Workunits will require far less than 80 CPU hours on your Pentim 4. Don't trust the inital estimate of the boinc manager, this is very pessimistic sometimes.
Let it run for some hours and you will probably see the estimated remaining time drop faster than the elapsed CPU time increases.

Yes they do both per Wikipedia and an Intel PDF on Socket 423 Pentium 4 processors from 1.3 to 2.0GHz.

Wow! Thank you all for a

Wow!
Thank you all for a lively discussion and answers to my questions on SSE2 and W2K.
Really, Thank you.
I am always impressed with the depth of the responses....
And if things get heated. No harm done. Just a discussion....
I thought I would pass on a neat link on some test code
that I should use to see what happens..
Enjoy!!
