Why the system keep hanging when using SuperMicro PDSME+ motherboard?

Problem:

The System recognize the USB DSS, Screen prompts for DSS operating System selection and on second screen 32bit/64bit. Monitor switched to "Loading.... "  for 30 sec. then monitor switched to "Loading 10% plus open-e Splash screen". After that the systems hangs.

After that, we moved the DSS UBS-Stick to another System, the DSS boots properly. Changed the Supermicro Motherboard to a new Spare Board same Type, same error.

We also noticed the following error messages:
1.) Error 14
2.) Segmentation Fault
3.) mount: mounting/dev/mapps/changes.img on memory/rootcopy faild: no such file or directory

The Hardware that has issues is: 
Supermicro PDSME+ with latest BIOS (brand new)
RAM 2GB ECC

XEON Processor 3050.
3Ware 9650SE 8Ports

We are using DSS Version 5 with the latest Update 2009-06-04 v.5.00 up62 b.3518.

Is there any incompatibility with Supermicro PDSME+

Solution:

After investigation; SUPERMICRO PDSME+  boards can handle "non ECC" DDR2 memory. In the specification and manuals are special vendors and types recommended. Our installation with "non ECC" memory was not successful. Only with ECC memory
we could install DSS 5.0 properly.

The build in memory test on non ECC memory didn't show any errors.

Please make sure to use ECC from following manufactures, or look on Supermicro website for tested memory on each specific board.
