Re: P50 Can not Find BIOS ECC Option ??

Hi AtliJarl:

 

the "wmic MEMORYCHIP get DataWidth,TotalWidth" is only report if your ram have ECC Bit then totalwidth will > datawidth

 

https://msdn.microsoft.com/zh-tw/library/windows/desktop/aa394347(v=vs.85).aspx

 

TotalWidth

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.

Re: P50 Can not Find BIOS ECC Option ??

So far none of the tests/observations can prove ECC is functioning (maybe it is, maybe not).  I hope Lenovo/Intel can come up with a way to prove that ECC *is* working!

Re: P50 Can not Find BIOS ECC Option ??

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.

 

Thank you,

Re: P50 Can not Find BIOS ECC Option ??

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.

 

Thank you,

Re: P50 Can not Find BIOS ECC Option ??

To clarify, this applies to all BIOS versions.

 

I do not have the release date for BIOS v1.18 but it will be made available when it passes verification testing.

 

Thank you,
