I'd replace that stick of memory just to be safe. you can also swap a stick with one of the others and see if the memory error travels to it. That would confirm the chip is bad.

Sounds like one of your Dimms is failing. A 2850 is a bit long in the tooth and oxidation on the connector may be a factor.  Have you done the basic reseating of the dimm modules yet? Sometimes it works, sometimes you have to identify the bad module and pull it. I don't believe the 2850 has the option to disable ECC in bios, but you could look.  If you can, and it gets you past the problem for now, don't wait very long to get the proper repair done.

Has the amber light been on the server with the SBE Logging Disabled since June, without being restarted?

Clear the Hardware/ESM Logs (in OMSA or through DRAC, if installed), reseat the memory, swap 1B with 1A, and run the test again.  If the error returns on 1A, then replace the memory DIMM.  If it returns on 1B, you have a bad memory slot.  If it doesn't return, update your system firmware (BIOS, ESM, etc.), which you should do after replacing any faulty memory too.
