During a chat with one of the motherboard manufacturers we were told that X58 motherboards will be no less than six layers, and might even need eight layers. The reason for this is the triple-channel memory configuration, as it brings with it at least a couple of issues when it comes to motherboard construction.
First of all, it's a matter of getting the traces down, six DDR3 memory slots uses a lot of traces on a motherboard and this requires extra layers. The other problem is that there will be signal leakage if the extra layers aren't used, which will cause all sorts of problems, including instability and data loss.
