What is the slowest and/or oldest BOINC machine you've had successfully crunching? I dragged an old 486/33 running Windows 95 out of the closet (an IBM PS/1) and am having difficulties getting BOINC to run properly on it. So, that would probably make my "slowest" an old iMac G3 233 MHz, or a K6-2 233; those may seem staggeringly slow by today's standards, but I'm sure someone can top that since they're only about 15 years old.

It may sound like a silly title but it's a more attainable goal than having the fastest machine, as the slowest isn't a moving target.

I have an AMD 2600+ (CPU runs stock @1.9 Ghz, wont overclock) and an Intel P4 @1.8 GHz (overclocked to ~2.2 Ghz), both running Win XP PRO SP3.
They were built from 3 PC's canabalized for parts to make 2 working "winter space heaters" (especially when running Prime Grid or SETI).

Have attempted to install Ubuntu Linux several times on the AMD as a dual-boot or outright but it just fails to work.

My slowest/oldest desktop is a non-HT 1.8GHz P4 running Ubuntu 8.04. Built and rebuilt many times from bits. Only really there for trying out linux-only projects rather than serious number crunching. If there's no new projects to try I just leave it running Asteroids or Primaboinca as at least it scrapes a modest amount of credit on those :)

Oh, got a fairly recent dual-core (or is it HT?) netbook thingy running XP that's too small and slow too use for anything useful so that gets used to try out new projects but otherwise just crunches Primaboinca and still gets a dismal amount of work done.

Cheers,

Al.

That's all you've got, Pentium 4/Athlon generation? Those are all capable of handling many modern tasks. I'm looking for stuff that's in the sub-1 GHz category; if it can run Windows XP, we're talking too new.

I've got a bunch of Raspberry Pi's. Not too old but base speed of the ARM is 700Mhz, got mine OC'ed to 900Mhz. Still takes 31 hours for an Einstein BRP4 work unit.

I ran BOINC on four Power Macintosh 7500s (PPC 601 CPU, introduced 1995), each upgraded to a 500 Mhz G3 processor. They ran OS/X slowly, but without a glitch. SETI@Home computer ID numbers are 2049370, 1994763, 2044006, and 2043989. Wife made me retire them - new house has no basement.

I've got one of those that I used on my workbench, though it's been down since the hard drive died and I haven't gotten around to replacing it yet.
