<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>We
have a dual Opteron Motherboard Tyans S2881 with 4Gb or Ram.</FONT></SPAN></DIV>
<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>We
have installed RedHat enterpise V3 AS and it recognizes the
memory without problem.</FONT></SPAN></DIV>
<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>We
have trouble however finding the sata controller, REdHat does not find or
recognize the device.</FONT></SPAN></DIV>
<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>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. </FONT></SPAN></DIV>
<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>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.</FONT></SPAN></DIV>
<DIV><SPAN class=936384913-01042004><FONT face=Arial color=#0000ff size=2>As far
as the other remarks: I cannot really tell. </FONT></SPAN></DIV>

physical memory support under RHEL for Opteron<BR><BR></FONT></DIV><BR>
<P><FONT face=Arial color=#0000ff size=2>Hi,</FONT> </P>
<P><FONT face=Arial color=#0000ff size=2>I am just about to order an dual
Opteron 248 server to run under RHEL AS.</FONT> </P>
<P><FONT face=Arial color=#0000ff size=2>I would like to double check the
physical memory supported - we are getting</FONT> <BR><FONT face=Arial
color=#0000ff size=2>8 x 2GB PC3200 or PC2700 memory on this server.</FONT>
</P>
<P><FONT face=Arial color=#0000ff size=2>I have found something a bit obscure

<P><B><FONT face="Times New Roman">**</FONT></B><FONT face="Times New Roman">
64GB is the maximum memory size for X86 systems. Maximum memory sizes vary
with other architectures.</FONT> </P>
<P><FONT face=Arial color=#0000ff size=2>Can anyone confirm </FONT><BR><FONT
face=Arial color=#0000ff size=2>a. the maximum memory size for Opterons
supported, and</FONT> <BR><FONT face=Arial color=#0000ff size=2>b. the maximum
