Peter,
We have a dual Opteron Motherboard Tyans S2881 with 4Gb or Ram.
We have installed RedHat enterpise V3 AS and it recognizes the memory
without problem.
We have trouble however finding the sata controller, REdHat does not
find or recognize the device.
The physical limit of our motherboard is 16GB RAM but as we have 2*4
banks of memory and 2GB chips are not on the market yet, we have
installed 4GB.
I do not know what the limit is that the opteron processor can address,
but if you plan on installing a dual motherboard with 64 bit processors,
the processors can probably allocate much more memory than can be put on
your motherboard.
As far as the other remarks: I cannot really tell.
Best regards and good luck.
Herwig

Subject: physical memory support under RHEL for Opteron
Hi,
I am just about to order an dual Opteron 248 server to run under
RHEL AS.
I would like to double check the physical memory supported - we
are getting
8 x 2GB PC3200 or PC2700 memory on this server.
I have found something a bit obscure on the RH web page:
http://www.redhat.com/software/rhel/as/
<
http://www.redhat.com/software/rhel/as/
>
in that it said:
** 64GB is the maximum memory size for X86 systems. Maximum
memory sizes vary with other architectures.
Can anyone confirm
a. the maximum memory size for Opterons supported, and
b. the maximum usable physical memory per process on user
applications
Thanks a lot.
Peter
