Oh look, another EVGA board...

x58 chipset supports 24GB of ram max.

Not true, since the memory controller is not in the X58, but in the CPU. The reason why 24GB is max on many X58 board is that Over 4GB memory stick are rare and cost like hell, even tho 4GB memory sticks are also expensive.

There are couple Dual LGA1366 server boards which support up to 144GB of DDR3, but 96GB is usually max on server boards.
