I'd use the newest bios, FI because it states: Fix: Some of 1000 GB (1TB) HDDs will be detected size error
. So, if you plan on using 1Tb drives or larger this may be required. The manual states nothing about ram other than both slots are needed for DDR, duh.
Rev2.1 of this board also states 4gb ram as well as rev6.6.http://www.gigabyte.com/products/product-page.aspx?pid=2425#ov
yet every retail site says 2gb of ram??? Sorry, I'm at a loss for ram.
