Memory probem ?
 

[FONT=Arial][SIZE=3]I get the following output from Prime95 around midnight every day (or at least on many days, I am not always there to check). Is this normal or do I have a memory problem I need to look into? Thanks in advance for your help.[/SIZE][/FONT]

Not enough memory available to run stage 2 now.
Will try again at a later time.

[FONT=Arial]By the way, does anyone know how I can save the screen output?[/FONT]

It is not a memory problem, ie bad chips. It is that Prime 95 uses a lot of memory to do the 'stage 2' part of the 'P-1' test. It is normally set to only to do it when a lot of memory is available (like at night).

Did you change the 'day time/night time' or 'memory' settings in Prime 95?
Have you read the help file?

Thanks for the help. Sorry to take so long to reply, I have been away all week. I had read the help file and increased the memory available but I had only increased it for the day settings before midnight. Prime 95 was starting factoring 5 minutes before midnight when it had lots of memory but five minutes later it was taken away again - unfortunate timing. It is working fine now; again thanks for the help to a newbie.
