C1 and C2 stepping

[Mjag01]

Asus Sabertooth x79, 3930K CPU, 64gb Kinston beast at 2133mhz.  In bios it states:  stepping C1.  In AIDA64 it states stepping C2.  I have VT-D enabled.  Which stepping is true?

Any advise will great.

Please let us know what the 3rd line on the Motherboard / CPUID page of AIDA64 says about the CPUID revision of your processor.


Thanks,

Revision number of CPUID:  000206D7H.

 

Hope this helps.

Thank you.  It's definitely not C1 stepping, but C2, so AIDA64 is correct.  C1 in the BIOS Setup may refer to the X79 PCH stepping.
