I have the same setup except for RAM. You don't need high Vcore. I just got a 512mb stick of Adata Vitesta PC4000. Using clockgen, I am currently running at 270x9 HTT, memory 1:1, HT multiplier = 3, at 1.55 Vcore and 2.8 Vdimm, albeit at 3-4-4-8, 1T timings. Using the BIOS you should be able get to 240x10.
I am not running a single SATA, but a RAID array with 2 Raptors on the Nvidia SATA 1 and 2. I have not tried SATA on the Promise controller. SATA is not affected by high FSB for me. I have AGP lock set to 66.
You will have to load the SATA drivers during install for a single drive.
I have read of problems running 2 x 512 sticks 1:1 on other boards. With double sided sticks, they default to 166 RAM divider. Some can, some can't, you won't know until you try.
