But it is!
It is just laid out differently.
Industry standard SDRAM chips but to get the wider memory path
they layed them out differently.
They used a different JDEC standard DIMM (the same as in some notebooks)
because the motherboard would have been a mess using the giant, more
commond desktop-PC JDEC standard modules.
The idea is a high-bandwith arch. at PC prices and to do that you have
to make some tough decisions. Otherwise the OCTANE is a far better (and $)
arch. that is just dying for faster processors and next-gen graphics.
Who cares. It is all in the application performance. We will soon see...
