I'll use it mainly for gaming
I heard from people at OC3D that the board doesn't support RAM higher then 1866 but my ram is 2000 so is that a problem? I'll be running 16GB of RAM in total.
i personaly havent had a problem running higher than recommended ram speeds haha my limit is 1333 on this foxconn p55a piece of crud, but honestly i don't really know what could happen
Actually the last QVL lists DDR3-2400 and the BIOS allows for up to DDR3-2666.
The ASUS Sabertooth Z77 is a very good MOBO with a 5 year warranty and all quality components. I like the Sabertooth series for it's active cooling of the chipset and VRM which is great for OC and water OC it helps keep those temps down for improved stability.
