Noob SuperPi question

Exactly what the title says? I never really used SuperPi before to test stability. What settings/calculations should I use?

For stability, do a 32M run. It should take you between half an hour and two hours depending on how fast your system is. Not really sure how good of a stability test it is, but some people like it.

More commonly, the 1M test is used a benchmark. Takes less than minute.

Calculated 1M w/ 19 iterations. 37 seconds elapsed.
good or bad?

top notch...very few systems will run faster.....

Nice PI score, but super PI for me is not the best stability tester. I have been able to do 32M Pi test at speeds that would error out pretty quick in Prime95.
Prime95 IMHO is a much better stability tester.

To give you a comparison the system in my sign does 41 seconds. You could use the search function to find the thread where a lot of people posted their scores. I know it was at least 2 pages (I think a lot more) of just 1M times.

Does a higher FSB help cut seconds off your superpi time.. or is it all about how many mhz you can get out of it?

It all helps quite a lot with SuperPI, although I've found that tight timings seem to matter more than much else. High clock speed, low mem speed and low latencies are optimal.

Version 2.0 of the super_pi for Linux OS
Fortran source program was translated into C program with version 19981204 of
f2c, then generated C source program was optimized manually.
pgcc 3.2-3 with compile option of "-fast -tp px -Mbuiltin -Minline=size:1000 -Mnoframe -Mnobounds -Mcache_align -Mdalign -Mnoreentrant" was used for the
compilation.
