I got these boards as soon as this Chipset debut because of the double x16 in Crossfire capability, but then when ATI's X2 came out that was a feature that became a bit useless.
The boards cost me $300+ at the time and they are good for high mem clocks DDR2@1300 with little voltage. They are also solid trustworthy boards but for that price DFI could have done a lot better.
The reason I believe is a fatal mistake made on the PWM-Chipset design for running Quads. They underestimated that for sure.
The max FSB I got out of a Quad was 485x9 but that stresses the board a lot, needs a lot of volts on NB/VTT/Vcore for that (with a board rev. A1).
So you have to chose between running 470x9 and low volts for everything (vtt, vnb. vdimm, vcore etc) or 485x9 with huge amount of volts.
I prefer to run it low volts and comfortable because the extra 15Mhz won't be missed.
With a new board in the near future that can change. I'm not thinking about i7 as it won't give me any gains in reality.
