You'll have to check that your motherboard and BIOS is compatible with
both chips as they have different pin counts.

When I stated above that I could replace the chip it was with the full knowledge that I can.

Are you sure it's dropping to only 3%/hr?

.per SetiSpy
.per fact it takes about 30 hours.

How long does it take to process a work unit on average over at least 10
work units?

Are you using the GUI screensaver or CLI command line version?

GUI version.  If there is a CLI version, I cannot find it at SETI@home.
Guidance welcome.

Can anyone guestimate my performance improvement if I replace the Celeron with a Pentium IV at the same clock speed?

Less than you'd think probably.

My P4-2.0GHz processes work units at an average rate of 3.5 hours each
and averaging 28% per hour, according to SetiWatch over the last 60 work
units.

Well, you're at about 10X the work rate with a slower clock.  So something about the P4 (all that F.P. and cache?) is better.

I'm running the command line version 3.08 in low priority mode all the
time, with SetiDriver for caching of work units.

Where do I get the CL version?

Thanks,
