WeadonJ,  The error you are receiving is stating that the memory is operational, but is at an early indicator of a possible future uncorrectable error. My suggestion would be to reseat the dimms, then run diagnostics on them to see if there is anything that shows up.  I would suggest booting to this diagnostic for the memory test. - [URL] Also, what revision is the BIOS and ESM/Drac sitting at? Are either up to date? Let me know what you find out.
I have a PowerEdge R720 running XenServer 6.2. We have received this error for the second time in the last 3 weeks: "MEM0005 Persistent correctable memory error limit reached for DIMM1,DIMM2,DIMM3,DIMM4,DIMM5,DIMM6,DIMM7,DIMM8 reseat memory". Two weeks ago when we got this error the first time, We powered off the server and made sure all the memory was properly seated (it was). We powered the server back on and the error was gone. Since this is a production box requiring HA, we did not take a bunch of time to run extra diagnostic tests. The error came back this morning. Does anyone have an idea of how we can resolve this issue? Thanks
