this server has 48 megs of ram in it. seti can't run on 48 megs of ram?

Nope. Sorry. Not sure what the absolute minimum is but 128 meg would allow it to run comfortably.
How fast is it? If it's not over say 233 or better you could add some ram and use it for the time being but anything slower than a 300-400 mhz computer would take a long time to crunch one of the new enhanced wu's. I have a PIII 500 mhz and it takes me anywhere from 60-90 hours. Of course the deadlines are a lot longer too so you could still crunch but it would take forever on one too slow. I know of a couple 233's crunching but not sure exactly how long they take. Think it's around 180 hours.

I can hook up with Jim-Rs point of view. It could be problematic, if enhanced will be released.
But I think, you can crunch seti without problems with this old system, till enhanched will be released. But the actuall seti would run about 60 hours on such a old system.

But there are some other usefulll boinc projects, which are not so CPU intensive like seti.
For example SIMAP need about 2,5 to 3 hours on a K6/450, Predictor@home about 10 hours (K6/450). Rosetta@home uses a fixed computing time, which could be setup by the user for 2/4/10/20 hours.
SIMAP download are about 1,25 MB, uploads about 200 to 500 KBs. Predictor has very small downloads, Rosetta has WUs about 3 to 5 MBs.

I am not shure about the memory requirements, but I think that they all need more than 64 MB Memory. If you wan't to crunch any project, I recommend you to a upgrade of the memory, too.
So far i know is SIMAP minimum 96 MBs, Rosetta recommends 256 MB or 512 MB (the application need about 70 to 90 MB memory on windows).

ah theres no point. this is a P1 133Mhz running CentOS 4.2. All it does is run samba for my extra files, and is literally on 24/7/365 hooked up to my dsl modem. I wanted to give the extra CPU time to something useful but I guess the computer is too old =(

That kinda makes me sad.

Yep. I had an old workhorse 486 that served me very well for many years but I happen to see a deal on an interesting game that I wanted but alas it wouldn't run on mine. Ended up having to put together this 500mhz p3 just to run it! And now I got interested in playing Quake 3 because it ran fine on this one and now they've come out with Quake 4 and I find that it will take three times the computer I have now to run. BTW, my workhorse is still pulling a plow! I've got it acting as a database server!
And at least yours is still being useful to you!

???? - If enhanced will be released, it could be that the system have not enougt computing power to complete a WUs within the deadline.
It is a P133 - the actual app could run about 100 to 120 hours....

i personally dont care how long it runs cause like i mentioned before itll be going 24/7/365. ill literally just start it up then forget about it.

too bad though. i really would have liked it to do something useful :(

I have a computer with 48M. I have it working on SZTAKI and LHC. You can

I had a couple of other computers that didn't meet the SETI system requirements and found that adding used memory to them was very cheap.
