Ye Olde Zotac Z68ITX: What was the good BIOS version?

Hey all,

I recently bought a NOS Zotac Z68ITX-A-E (it even works!) to get my i7-2600 going, but I have no idea what the BIOS history was. The Zotac website lists 2K111011 and 2K120619 as options, though my board has a BIOS numbered between those two. Back in the day there was a lot of discussion about what BIOS was best. Some produced coil whine, some overclocked like crap, some didn't have XMP support. Does anyone remember what the good ones where anymore?

Bumping the original four year old thread seems rude, but I can move this over there if that seems better.

Oh, and the version I've got on the board is 2.11.1210(I'm guessing that makes it 2K111210?). The Zotac site makes no mention of this version. Build date is October 11th, 2011.
