Strange RAM error during MacPro Diagnostic initialisation
we've just received our brand new Mac Pro Server (2010) 2,4GHz Intel 8-Core Xeon (two Quad-Core Xeon E5620 "Westmere") and (8x4GB) DDR3-1066/1333R ECC Original Samsung Memory from an authorized Mac Reseller.
Once the MacPro Hardware Diagnostic Selfcheck has been initialized, we do get a memory error message for all memory modules: Memory - DIMM 1 (test 50) - Memory - DIMM 1 Check SMBIOS for devices that are flagged as having an error. (see above). Running the full Hardware Diagnostic check works seamless and the test quits without any error.
Although we've successfully installed all memory modules (8x4GB), the Apple System Profiler recognized 28 GB RAM at first. Resetting P-RAM and SMC solved the problem. 32GB RAM show up.
We are really concerned about the memory error message. What does it mean?
The memory modules has been tested by our reseller and are officially supported. When I startup the MacPro Hardware Diagnostic Selfcheck with the default Apple memory (2GB), no error shows up.
I really appreciate any comments on this.
