On the G7, the installation went perfectly and the machine ran great for about 2 weeks, when it just seemed to "stop".  The system stopped responding on the network, and there was no video on the console (or remote console via iLO).  It would not reboot or cold boot through iLO, I actually had to hold the power to turn it off and then hit it again to power up.

This is interesting...  I tried to load memtest86 from the CentOS 5.5 
Install DVD, and the system immediately rebooted.  I eventually loaded 
memtest86 from an OpenSUSE 11.4 install DVD I had laying around, and 
that ran OK.

I ran memtest86+ starting Friday about 6 pm and stopping Monday morning 
at 10:45 am.  Almost 70 full passes were completed, and no errors were
