I've spent a couple hours this afternoon tuning FSB I/O strengths, GTL REF voltage levels, and VTT and NB core voltages on this new RD600 motherboard (thanks DFI!) and have managed to bring the board to an astonishing 460MHz FSB with an
Intel Xeon X3220 quad-core processor. As of last week I was only able to achieve these levels of FSB performance using the Intel P965 chipset, which is of course already a generation ahead of their flagship 975X chipset (way to go Intel marketing).
I'll be going into more detail on how to tune this board very soon, for the time being just know that only 1.59v (as set by BIOS) was required for NB core voltage. And I can't stress this enough - you
DO NOT need to slam 2 plus volts into the NB to get this MB to clock up....a little tuning goes a LONG way.
Some pictures to wet your appetite.
