The biggest difference I see with Bios 1.6 vs. 1.1 is the lowest Vcore setting for my Q6600 was 1.225v on 1.1 vs. 1.275v on the 1.6 bios. I have a GO stepping quad core. The 1.6 bios undervolts the vcore slightly while the 1.1 bios overvolted the vcore significantly, 1.225v could register 1.625v on bios 1.1.

The ADATA memory was tested by many professional sites all achieveing well in excess of 1066Mhz. One review guarantees over 1000Mhz while another guaranteed at least 1066Mhz. The ram is called DDR2 800+ and it's ADATA's performance ram.

I really like the MSI board and flashing the bios with a memory stick is easy.
