Memtest - How many loops = good?

[pelikan]

Does anyone know how to run Memtest86 from a CD? I downloaded the .iso memtest86 file and burned it to a CD but nothing happens when I try to boot from it (I just end up in Windows).

you have to change boot order to have cdrom before hd

RalfHutter: i know, thats why probably was in *'s...to create emphasis on it, but not act as the final say

ok, just ran the test with the "contra" code. 😉
I guess to let it run 10 loops you just gotta watch it? no way to make it stop once it hits 10?
anyway, I ran it once. took almost an hour for my 512mb pc2100 and xp1700.
no errors. 😀

This has turned into a very interesting thread. I always thought that Memtest only tested MEMORY, not your CPU overclock.

Maybe I should try these advanced settings, but IMO, any overclock that can do 24 hours of Prime95 torture test w/o errors is stable. I have personally had overclocks that passed memtest (default settings) passed 3dMark, passed sysmark2001, etc, but failed Prime95. To me, that's the yardstick.

I did change the boot order. Any other ideas?
Thanks a lot.

do you not have a FDD?

when you burn a CD to be bootable, you need to add a "boot sector" kinda thing. sorry, that's not a good description, but in Nero there is a special item to select for a bootable-CD burn.

unfortunately i'm running Memtest :Q on the computer that has the burner and Nero . . . 😀

FYI: When using Nero to burn this, just select File and Burn from image....When I did this, the resulting CD was bootable as the boot info is already in the ISO.

i totally missed that he used the ISO file!! 😀 i just grabbed the regular and put it on the a floppy . . .

i have an old CD-ROM that doesn't seem to be bootable even when in a new system and first in the boot order. just another thought!

Thanks for the help.

Last night I down loaded version 3 and ran it using the "contra" code. I let it run all night (28 loops) but I noticed that it only ran tests 1-10. Why didn't it include test 11 in the loop?

the default settings in memtest86 are pretty lame too :disgust:

for serious mode:
boot to the disk and press C-2-3-1-2-0-spacebar and let it run for 10+ passes (loops)

geez, what's wrong with you thug????

it's like... memorizing the cheat for the original contra on nintendo!!! 🙂

up down up down left right left right B A B A select start.

=)

Oh, how the time passes...

it runs test 11 ~ but it only takes 2 seconds to run that test 😉

How can I know if the error is CPU or mem related?

raise voltage of something (either cpu or ram), and then try again
if it still fails, raise voltage of other thing and try again

if it still fails, lower oc on one...then run....
if it still fails, then lower oc on other

a period of "guess and check" it seems...

I ran it for 9 hours overnight. 598 errors. That isn't good, is it? :0
