Re: memtest86 & memory test
Hi,
I think memtest86 is the best, but you could use something like
this bellow. Just adjust the value of N_MEGABYTES, and start as many
process as you want to full the fisical memory.
[start of code]
#include
#define N_MEGABYTES 160
#define TOTAL (N_MEGABYTES * 1024 * 1024)
int main(void)
{
int i;
char *p;
char *mem = malloc(TOTAL);
if ( mem == NULL )
{
perror("malloc");
return 1;
}
while ( 1 )
{
for (i = 0, p = mem; i < TOTAL; i++, p++)
{
if ( *p == 0 )
*p = 1;
*p <<= 1;
}
}
return 0;
}
[end of code]

The Linuxes tend to run memtest86 from the hard drive; you can do
that on FreeBSD as well. See the following relevant messages:

memory test off of a 'DISK-ON-KEY' device ... ?
I'm trying to run some tests on a new server that I'm putting together, and would like to run some memory tests ... I found memtest86, but it runs on floppies, which doesn't help me, since I don't have a floppy drive on this thing :( I've been doing my BIOS updates using a bootable USB Disk-on-Key device, and am wondering if anyone knows of a way of either getting memtest86 to "write" to this device *or* something else I can run that would do similar? I have FreeBSD 4.11 already installed, so if there is something *good* that I can just install from ports and run on the command line, that is cool too ... Thanks ... Marc G.

Tests 5 and 7 are not to be trusted. I found this out by own observations, and I believe (although I cannot remember where I read it) that tests 5 and 7 can be a bit iffy. The memory in question when in use and under stress showed no memory typical problems at all. The same memory tested on a system with a Pentium III also showed no failures with repeated running of these particular tests. -- Regards Cliff Sarginson The Netherlands [ This mail has been checked as virus-free ] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Au contraire; a syntax error in a "make buildworld" that cannot be repeated when issued again is almost always indicative of a memory error -- especially with a new out of box FreeBSD 4.7R -- and is generally considered a good memory stress test. I was rightly alerted to a memory error. I ran Memtest86, suggested by a list-member here, and indeed, one of the Kingston 512M DIMM's was acting up. I did some research; and Kingston memory appears to have known issues with the ASUS A7V333 board. I switched the DIMM with another computer, and now both run faultless again. - Mark To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Memory test?
I just did a makeshift memory stress test on a new machine; that is, I did a "make buildworld". Regrettably, it failed, saying it had a sytax error somewhere. :( So, I ran it again; and this time it went fine; then I reinstalled FreeBSD 4.7 altogether, and rebuilt world again. And, again, no problems. This is a bit worrysome. Does FreeBSD even notice bad memory? Would the kernel put a message in /var/log/messages? It did not show anything there when buildworld failed. - Mark To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
