Confirm working.. I build and tested one unit using the same board and processor and it is running without a flaw.. Tho I'm not sure the board I'm using is running on what bios version.. But as far as I know, the normal retail sold motherboard dont have problem supporting the processor.. Another 2 board I tested is an Asrock Z77 Extreme 6 + Gigabyte Z77m-d3h

With the latest cpu-z I tested plus what Window show me, it all display the full name plus speed of the processor..

The only thing I have not test are those H61, P67 and Z68 boards with bios that can support IvyBridge.. Although some of those board cpu list do list support for the Core i Ivys, but I did not notice the Xeon Ivy listed..

But the problem does not appear for Z77 which I can confirm..
