Lowest CPU for crunchers these days

[BCinSC]

My fleet is aging (aren't we all) and I wonder if the Xeon 333's have enough oomph to even bother anymore. How about P2/450, P3/450-600? Xeon 500/550? I'm pretty sure Dual P3/933 still has life, as do all P3 Tualatins (1.1-1.7GHz). By project, what's the lowest?
FaD
F@H
SETI
D2OL

F@H can be run on just about anything in theory, but beyond a certain point you're better off not wasting electricity. Regardless, if you want to run it on any P2 or P3s less than around 400MHz (or a bit higher if the system is used heavily), or < 500MHz Celerons, then you should enable the no-deadline work units so the system will be able to finish them "on time."

I personally still have a PIII 600 and it's doing darn fine on any project I do (besides ClimatePrediciton.Net). The P2 and Xeon333 are indeed questionable. Not so much of their CPU power, which is slow but hey, they do crunch! I'd be more concerned about power/output ratio here. I don't know your electricity bill, but if you aren't concerned with that particular bill: go fire 'em all up!

i run DPAD on a PII 333 🙂

I still run a 333mhz P2 and it crunches just fine. It finishes the smaller WU's but every little bit helps.

I shut down my p2 350 a while back as the power used didn't match the output but I had 18 machines running at the time

My brother is crunching FaD for me on his PIII 600 laptop (running win2k). I also crunched FaD for many months using my old PIII 666 desktop.

I'm still running SETI on my PII-266 laptop. All that laptop does is crunch SETI and run SetiQueue for my herd. Although, I'm moving soon and may shut down the PII-266 for good and move my SetiQueue onto another machine... Also, until a year ago, I was still running SETI on PII-350's, 400's, a P-233 and a PPRO-200.
