Hi there guys this may sound funny to some but i haw a P II just sitting in a box and i want to attach it to Seti i downloaded the optimise MMX app
and i was wondering if i can make it haw more than
233 MHz...and if i can will it make some diferenc ore i should just leve it as it was?
Oh yea and is 65 mb of RAM enough?

No 65 meg of ram is NOT enough, you need 64 meg free AFTER the OS loads.
As for the 233mhz being able to finish one unit within 10 days, I would not think so.

Mikey is certainly correct that 64MB alone will not be enough, however, w/ a PII 233MMX SHOULD be able to crunch a WU in less than 10 days (864000 seconds), especially w/ the new mmx opt ap.
If you could somehow find some additional memory for almost nothing (local computer store salvage,ebay?) since in many cases PCs this old are often just tossed or donated (sorry, no offense), perhaps it's worth a go.

This merchant seems to offer some choices. Seems EDO and DSRAM was used in PII mmx models, though I can't remember which was used in my laptop as I upgraded my Compaq Armada 233MMX from 64MB to 256MB when I first started running Seti Classic.

http://www.memorystore.com/config_generic.asp?cboLevel1=64
If you can get 256MB free/cheap, run a minimum-install of Win 95 or 98, and shutdown unnecessary services, it should work, albiet like watching each grain of sand fall individually in an hourglass.......

Just depends on whether the novelty factor is worth the time, possible inconvenience and maybe a few bucks to crunch WUs that will likely take several days to complete. Electricity to run this 24/7 won't be cheap either.

Cheers!

Its ok i got that pc for free:)
I hawe 2 memory cards but i dont know how much MB they hawe...ill see.
electricity is not a bigg problem thank god:)
I want to hawe more pc's on seti(but i cant aford faster pc's)thats why i want to attach any pc i can get for free ore almost free.

64 megs isn't much. However, With the release of the new Enhanced WUs, I believe the old requirement of 64 (useable) megs has been reduced to 32 useable megs, so you might just try it out. What could it hurt?

Although 64 MiB (67108864 bytes) used to be required, with setiathome_enhanced the requirement has been reduced to 31 MiB. The system as described could be attached and would get work. There is a difference for systems reporting under 64 MiB; they do not use an extra 32 MiB which speeds up chirping. That has an effect on speed which adds a nearly constant amount of time to crunching each WU, the percentage change would be greatest for the quick VHAR WUs (angle range 1.13 and above). Those are also the WUs with the short 4.34 day deadlines, so a slow system with small memory could get into trouble.

But my Pentium 200 MMX overdrive system with 128 MiB does those VHAR units with an MMX optimised app in 27 or 28 hours. I think a PII 233 MHz without the chirp speedup might take as much as 36 hours, but that gives plenty of margin to meet deadline if the system is crunching S@H 24/7. For long WUs, my system has taken as much as 6 days and 16 hours but those WUs have deadlines about a month out so there's no concern, and I'd guess the 233 would actually be a bit quicker there even without additional memory.

Whether it is worthwhile crunching with these slow systems is a matter of personal choice, in my case that 200 MHz system has been crunching S@H WUs since 1996 and will continue indefinitely.

I'll second that. My 233MHz 96MB crunches comfortably
inside the deadlines set for the enhanced WU's. It just
finished one in 111 hours and has 18 days remaining before
the deadline. Even have a 1.5 day cache setting to make
sure it does not run out of work.

Not sure what effect your less memory might
have, but hard to believe it would enough to break it.

Recent WU's seem to fall into 3 buckets:
~30 hours
~65 hours
~110 hours

I've even had some short units come along and preempt
the CPU, and there was still no problem. This is with
latest stock BOINC and SETI app.

Crunch On!

I also have some equipment in this age range. I noticed the other day that one of them is currently working on a unit that demands 80 MB. It's KWSN's source/scripts built for mmx only. That is the first that I've noticed the higher memory usage, but now I see other units taking more than ~30 MB sometimes.

Hey guys, where can I find this MMX optimated app? Does it really uses sth.?

Thanks.

Well I had a P-II 400MHz crunching SETI@Home and it took it about 2days for one WU. I'm going to have 10 Celeron III CPUs crunching SETI@Home and I hope that they will crunch one WU in 3 days each...

You're seriously under-estimating your Celeron 3s :o)

My Duron 800 is definitely slower than a Celeron 3 with the same MHz - I used to have a Celeron 566 that I could clock at 850 MHz without any problems at all (simply change bus speed from 66 to 100 MHz and use RAM that can take it). Celeron 3s have less cache than P3s, but still way more than the Duron, and the longest time it took to crunch an enhanced WU (with my optimized SSE client, though, not the standard) was ~80000 seconds.

One day has 86400 seconds, so I'd assume your Celerons will get comparable times to that, though they will probably be quicker. 3 days for one WU each? More like 4 or 5 in 3 days :o)

Simon.

Ahh I'm sorry. I typed Celeron III? Argh! I meant Celeron 300MHz! LoL!

Sorry.
