I'm having issues with my configuration of an S5500BC, on the latest 64 BIOS, 32GB RDIMM (4x8), with 2x e5620 Xeons.
The Chassis is a Intel SC5650BRP which has a 600w PSU installed.
Randomly, the system will restart, it is running unRaid which is based on linux, but I am unable to capture a kernel panic, its almost as if someone has turned off the power then turned it back on. I have monitored this by setting up a webcam to watch the console output on the VGA screen. Sometimes it will run for a few hours, or a few days before rebooting, it doesn't seem to correlate to periods of high activity or usage on the system.
The error manager in the BIOS is blank, I have not yet checked the SEL log.
All the components test fine, I've ran tests on the memory and CPU's, the memory has actually been completely replaced with a different brand and the problem persists.
I have seen a couple of other threads on here with similar issues, but ultimately, no solution.
The board has come to me second hand so I don't know the history, its not impossible that it might just be failing given its age.
Any thoughts?
