When I tell Prime95 to do ECM via the menu, it adds this entry to worktodo.ini:

Code:
ECM2=1,2,791,1,11000000,0,736,0,0
But this crashes Prime95 if I move it to the top as well...

Is "CpuSupportsSSE2=0" set in local.ini?

No... If I add that line to local.ini Prime95 crashes no matter what I do...

I can (I think!) provide remote desktop access to this box if you want...

Which form of the ECM line is the correct one for me to use?

Both should work.
ECM is the old syntax, when only 2^x +/-1 was supported.
ECM2 is the new syntax, for numbers of the form k*b^n +/-1.

2^791+1 works for both, and AFAIK, there is no difference.

Hi, I was trying the beta version 24.11 of Prime95 and noticed that it has some troubles using a proxy server. On the same machine with the same configuration version 23.8 works ok. But using 24.11 I get an "error 1". I tried setting "Debug=1" and noticed that the first request issued by the program to the proxy is successful, while the second is invalid. And I mean it is an invalid URL (unforunately I can't report it because at the moment I don't have direct access to the machine), as part of the address is missing (if I remember right, it's something of the form "http://mersenne.org[xxx]", where the "[xxx]" is something related to the version and to the previous request; so at least one "/" is missing). I hope this information is enough, sorry if I can't post the exact log messages.

For now, add "SendPortNumber=1" to primenet.ini
