the "wmic MEMORYCHIP get DataWidth,TotalWidth" is only report if your ram have ECC Bit then totalwidth will > datawidth
Data type: uint16 Access type: Read-only
Total width, in bits, of the physical memory, including check or error correction bits. If there are no error correction bits, the value in this property should match what is specified for the DataWidth property.
This value comes from the Total Width member of the Memory Device structure in the SMBIOS information.
wish ThinkStations team will fix the BIOS A.S.A.P.
thanks for your help.

Did you try option #4 and #5 in https://www.pugetsystems.com/labs/articles/How-to-Check-ECC-RAM-Functionality-462/

#4 just check is ECC Ram, so i didn't try that.

Unfortunately ECC Didn't working....

Think Engineering wanted to provide feedback to customer questions of where to find or how to enable ECC in the BIOS for P50 and P70 ThinkPads.
BIOS for the P50 and P70 are designed to enable ECC automatically when ECC-capable DIMM memory is installed. As a result, ECC functionality cannot be disabled or enabled when the hardware does not support it.
When ECC is enabled, the BIOS Setup main page shows the installed memory size with the notation “(with ECC)” as seen in this picture:
When the hardware requirements are not met for ECC, the above notation will be missing.

my ecc ram come from lenovo original build 2 x 16G ECC Samsung M474A2K43BB1-CPB
it can deteected by aida64 or lenovo solution center, that are ECC RAM, but BIOS Shows does not like yours
my bios photo are here https://drive.google.com/file/d/0B2rmah5yNRnjdkV0eVZpZXRuQzQ/view?usp=sharing
thank you for your help, maybe Engineering should do more works...

Yes, Amy -- a new BIOS would be helpful.
Can you also find-out how hardware RAID functionality can be enabled, after a P70 is shipped -- there must be some means to achive this.
