Intel is going to launch new revsion of their Sandybridge-E. Revison will go from C1 to C2. Description of Change to the Customer: Due to limited supply, Intel is initiating a rapid C-1 to C-2 stepping conversion for the Intel® Core™ i7-3960X Processor Extreme Edition and the i7-3930K Processors. As part of this transition the following changes apply:

• New S-spec and MM numbers for the converting products
• VT-d erratum removed for C-2 step.

Refer to Processor Sighting# 3876388 in Sandy Bridge-EN/EP/EX Processor Sightings Report – NDA (#452856). Customer Impact of Change and Recommended Action: Intel anticipates no change to customer platforms designed to Intel guidelines.

Customer’s boards can enable or disable processor Intel VT-d through their BIOS if they desire. If customer chooses to enable Intel VT-d, regression testing is recommended to ensure their board is properly enabled.

I hope it will be a good CPU to overclock !
