Hey scott, and anyone else with an x58 board from gigabyte.
The more recent bios for the Gigabyte x58 boards introduce dynamic vCore, so instead of idling at 1.3v and Tcase and Core temps being 37C and 40C, i idle at .8v and 28C. Idle CPU power consumption dropped ~25 watts. The last bios for the UD4P stablaized the memory controller and north bridge quite a bit, making it easier to push things (>210 Bclk I needed to change clock drive and CPU or IOH skew). My 220mhz BClk ran perfectly fine for 6 hours using less QPI, IOH voltage, less clock drive voltage and no clock skew. Before it took quite a bit of dialing in and if one setting was off by one or two notches I would fail prime95 between 10 and 15 minutes depending on what it was.
You can get them either from the Gigabyte site, or from
tweaktown. Gigabyte has made this real easy for you, you just load hit DEL durring post, or go into the bios and hit F8 to select QFLASH with a USB drive with the latest bios saved on it. This is the easiest (and safest) flashing a bios has ever been for me. A few of the "Senior Members" and mods over at tweaktown do testing for Gigabyte and intel so the often release beta/internal bios that you can't get on the gigabyte site. One of the bios allows the 920 to be locked at 21x (same as forcing Turbo mode and turning off Speed step)
