Hi there, has anyone run into any Desktop/Workstation Intel brand
motherboards that work with CentOS 5.1 (4.6/3.9 out of box
compatibility is a very large plus) and work with the 1333MHZ cpus
such as the 8400/9450 and accept 8GB of RAM? The closest we’ve found
so far is the DG31PR which is alright but it has the limitation of 4GB
of RAM and an unsupported Realtek NIC. The DQ35JO is also ok, but
requires quite a bit of ‘jostling’ to get to work such as pci=nommconf
and other tweaks, we need something that will work out of box, anyone
found anything recently?
Thanks in advance if anyone has any hints.

Drew,
Typically Linux hackers can hack the kernel to use very large RAM.
Current applications are built to access up to 4Gb RAM at a time only.
For machines with RAM of more than 4Gb you need to verify that the CPU
comes with Physical Address Extensions (PAE). Call Intel to verify this
CPU is with PAE. So, now its the Linux kernel that you need to turn to.
CentOS 5.1 64 bit should not have this limitation. However, the
following method allows up to 64Gb out of box for CentOS 5.1 32bit (u
can try this if the 64bit didnt work out).
Do the following in runlevel 3 as root user;
# yum install kernel-PAE
# reboot
# free
But all this needs to come with distributed swap and use of appropriate
file system type to ensure performance.
