Current Client (Prime95/mprime)
Should i update my old client (<v2.5)?
Yes absolutely. An update is recommend for several reasons. Besides that, the old client will still work for a long time.
Why doesn't my client run a P-1 test?
Automatic P-1 factoring will begin when n>17.2M. n-values below this have already been or are in the process of being factored manually.
How often is work reported to the server?
The default value is once a day. You can change this under Options > Preferences and change the Days between sending new end dates value from 1 to 7 days. The most often the client will report is once per day, unless you manually tell it to by going to Advanced > Manual Communication.
I want to run the client on a specific number of cores!
Go to Test > Worker Windows and change the values in this window. The number of worker windows * Multithreading = Total number of cores that will be used. You may also set the CPU affinity in this window to force it to run on a specific core or cores.
Is it possible to run SB and GIMPS together?
Prime95 cannot connect to two different servers. If you want to run both projects, you should use two copies of the prime95 folder. Let each folder connect to a different server and let those use half of your cores (see above).
prime.txt doesn't look right in Notepad!
The customized copy of prime.txt that is downloaded from the SoB website uses UNIX newlines instead of DOS, which Notepad does not display properly. Opening the file in WordPad or a more advanced text editor will display properly. Once Prime95 is ran and settings are saved for the first time, it will convert to use DOS newlines and will display correctly in notepad after that.
Legacy SoB Client (up to 2.5.0)
I've lost a test, what do I do?
I am behind a firewall, can I get the client to connect to the Seventeen or Bust server?
Yes, you can; if you are behind a firewall that filters the port the server uses, change the server to be sbp.pns.net and the port to be either 22 or 80, since those are commonly unfiltered (ssh and http, respectivly). Credit: Alien88 [Mike Garrison]
