I am running Windows 7 Professional 64-bit with 8 GB of RAM on a Gigabyte GA-EP45- UD3P (rev. 1.6). It took close to 20 seconds to wake from "Sleep" with default power settings. "Hibernate" is set to "Never," and I tried turning-off "Hybrid Sleep," which did not help. BIOS is set for S3 (STR). Something was just not right, so I updated the FC BIOS dated November 2009 to the current FE. Now, I'm back in business in two seconds. Just so you know.
