Legit Reviews noticed Intel released a BIOS update for its DX79SI "Siler" motherboard that activates PCI Express 3.0 support.
You can download the BIOS update over here.
Intel just sent us word that they have released BIOS Version 0424 (SIX7910J.86A.0424.2012.0127.1620) for their DX79SI motherboard! This BIOS update includes 20 fixes, updates or new features! We've been asking Intel why their flagship Sandy Bridge-E motherboard doesn't support PCI Express 3.0 for weeks and it appears that with this BIOS update the board now supports the PCI Express 3.0 specification. This is good news for AMD Radeon HD 7900 video card owners as they can run their card at its full potential. Sure, the gains of PCI Express 3.0 are hardly noticeable, but at least the board now supports it!

Many familiar settings were found in the most unexpected places, and the search process was accompanied by a quiet nonevil words. The familiar layout of the controls already was postponed on the reflex level, and when the usual "address" to come across a void, a little brain freeze. There is a positive side in an alternative vision of a convenient BIOS Setup Menu. For example, some tabs are provided with prompts, made ASCII-art proficiency at the bottom or right of the settings. This is very helpful. Also, when you change a setting on the bottom of the screen highlighted in yellow Changed, indicating that the user has made some changes in the last configuration. Very well implemented "custom overclocking", hiding in paragraph Overclocking Assistant. For its activation is sufficient to set the value of Automatic, and in the following paragraph appears Processor Speed to determine the desired frequency of the processor.
