Since I have done some upgrades I now have a home file server at home(Athlon TB 800 + 1GB PC133)

My question does seti rely more on clock speed or memory or a combination of both? I really dont know much about the program but decided maybe I can put that machine to good use. Will it make much of a difference if I slap another 512 into it or not?

Thanks.

Seti never really uses more than 25MB of RAM for me. I dont think putting another RAM chip in it will help. (As it is more processor intensive)

Yep,SETI v3.03 CLI uses only about 15MB so more RAM won't help you.

What SETI likes is as big & as fast cache as possible ,then fast RAM, low latency in preference of max MHz(bandwidth).If your RAM can take it then you'll cut quite a bit of WU times by CAS & RAS etc timings being set to 2 instead of 3.Be careful here though ,if your RAM can't take it you could potentialy corrupt data on your HDD!.

As for CPU speed you want the highest you can stabley achieve without going to FSB speeds that need high RAM latencies.
e.g an old XP1500 I had on an A7V266-E could go to near 1.6GHz ,but that meant setting the RAM timings to 3-3-2-6 on the FSB needed (about 158MHz) ,that was slower so I settled for 152MHz FSB with 2-2-2-6 timings & 1.52GHz

Inccidently Durons based on the Morgan core (mostly 1-1.3GHz) are much faster than Tbirds clock for clock at SETI when on the same FSB (their fairly easy to unlock) & are a cheap upgrade;) (if you can still find any)
