Mobo Makers Unhappy about Athlon 64 6+ Layer Motherboards

The Inq: <a href="http://www.theinquirer.net/?article=11893" target=_blank>Taiwan Inc unhappy about six layer Athlon 64 boards</a>
<i>
THE BIT ABOUT 939 pins being easier to do on a 4 layer board is spot on. Taiwan, inc is Really Unhappy about the cost of the 6+ layer boards.
However, my source also tells me that there is no fundamental reason for registered vs non-registered DIMMs being required by the silicon. He also told me that the memory controller was a cut/paste/tweak from the AMD 76x series north bridge (which supports both types).
If you look up the docs in the BIOS/Kernel writers guide, you can see all the settings to change for registered vs non-registered memory. All that happens is signal timing is changed to accomodate for the extra latency in the registered DIMMs.
My source tells me that the bios writers can easily do both registered and unregistered memory on both the 754, 939 and 940 pin cpus and motherboards, providing the motherboard trace layouts are adequate.</i>
