No, Memtest must be ran from the CD (e.g. boot of the CD) so that is not
a good solution for a remote test. I don't know of any that can be run
remotely.

Memory test

2007-02-05 Thread Y Sidhu

I need to checkout memory on a remote machine. I see there is memtest and
memtest86 out there. Which one is appropriate for my situation?: CPU is a
dual cpu, dual core SMP Intel Xeon. Can I run either program while the
machine is performing other tasks?**

There are others in the ports, but they aren't nearly as effective.  
Of course, if you really want "effective," there is no substitute
for a dedicated device...

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 ... ?

2005-09-12 Thread Marc G. Fournier


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 ...

Well, you can also get a Linux kernel with httpd built-in :)

As an aside, memtest *can* show false positivies on some Asus
motherboards with AMD chips. 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.

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.

I'm not sure what you're getting at.  You've seen just one failure,
and it is of a type that is highly unlikely to be memory-related.

Memory test?

2002-11-29 Thread Mark
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.
