Description Harald Koenig 2006-02-06 18:55:12 UTC 
your memtest86 doesn't work on a 2*2 core Opteron with 8 GB ram.

it locks up completely after 00:06 seconds with 50% in the very first Test #0
when it accesses the 4+ GB the first time (1st test cycle is for 100k-3GB,
then it steps to 4GB-6GB and locks up).

your memtest 3.2 also detects the CPU as "Athlon" instead of "Opteron".


I've picked memtest86+ 1.65 from http://www.memtest.org

this version 
a) doesn't lock up
b) detects "Opteron"
c) has much faster screen output


please use memtest86+ 1.65  which seems much more decent than you 3.20 !!

Tirsten, did you incorporate the new memtest?

now that I installed the 10.1 GM/final I can report:

it's still the old, broken and unsupported memtest :-(

really pitty, that was a pretty easy change which really doesn't have many depenecies to be considered...

Re-Tested internal with an Core 2 Duo Conroe on i975x and 4GB of RAM. Only memtest86+ was useful in this case.
=> strongly consider upgrading memtest86 to memtest86+

memtest86+ now in STABLE.
