There hasn't been a BIOS update for that board for about three years, now. Whatever is on the website is going to be the latest there was.
I didn't see that SL spec on http://ark.intel.com/Search.aspx?q=SL7PE though, so I don't see any more details on it
Have you tried asking over in the processor community?
That's a single core processor. With HT enabled, you got 4 logical processors. So it seems nothing is wrong here. And yes it is a 64-bit processor.
Hye Edward ;
Thanks for your post.
I would like too official sources but I works fine!
