I want an Intel I9 mobo with more than 2 SATA3 (6 mB/sec) connections, but it appears that only one company makes these.

Why is that?

And why are I9 boards limited to 1333 mhz with 1600 mHz tri channel memory readily available and cheap

Welcome to Tom's Forums!

Do you mean Intel i7? And the i7 Sandy Bridge is not limited to 1333 MHz RAM, but 1600 CAS 8/9 offers the best performance. The i7 Sandy Bridge IMC {Integrated Memory Controller} is 'rated' for 1066/1333 MHz but it supports speeds up to 2200 MHz -- but with little gains.
