Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

It's just for hobby sake, not my main machine. Something to play with, see what I can get it to do.

You could definitely get it to cook an egg.

Didn't realise the Super PI benchmark would take so long lol. Stopped it after Loop 2 finished.

45s initial value finished
2m 59s loop 1 finished
5m 33s loop 2 finished
perhaps this gives you some indication, I don't know.


Strangely, I just got 168.6 seconds in wprime 32m. Last time I ran it (I believe it was 4.5GHz) it was 68 seconds, 10 seconds slower than my OC'd dual Tualatins. I assume it's because of the change in memory divider. I might have a play with that next.

EDIT: Ok I couldn't get it to boot with 1:1 but 5:4 worked. got 88.25 seconds on wprime 32m. I guess the 68 second time was due to 1:1 at 4.5GHz due to more memory bandwidth. If it's memory bandwidth intensive, stuffs me how my dual Tualatins got such a good score. I suspect the best result I'd get with Super PI would be at the highest clock I can remain at 1:1 with.

As far as I can remember, SuperPI is a seriously weird benchmark. It relies heavily on the x87 floating point stuff, which was de-emphasised in later processors (because SSE does it better).

super pi 32m takes a long time to complete with slower CPUs...
just use 1m, it should be easily under 1 min (but over 30s)

Nah, Cedar Mill (particularly the 65W D0 stepping) runs cool.

I'll put it through super PI 1M next time I play with it, which will be whenever the 3.6 chip arrives. Then i'll have a better cooler and ram installed also.

As long as you are having fun then it's all good.
