Here is a different spin for why Asrock discontinued the 775Dual-VSTA in favour of the 4CoreDual-VSTA from (atlr) in a different thread.

Perhaps it's just a name change to make things super clear?

That Asrock link now shows the 775Dual-VSTA does NOT support quad core. I think the reason the 775QuadCore-VSTA was creeated is the same reason that Dell updated the XPS 700 to 710. The quad core processor has hardware design requirements that the 775Dual-VSTA may lack.

"As most of you know, Intel's Core 2 Extreme QX 6700 Quad-core processor will ship soon. Several of you have asked if this new processor will work on your existing XPS 700 motherboard.
...
Here?s what our development team had to say. Based on Intel?s current design guidelines, the Intel Quad Core Extreme Processor should work on the XPS 700 motherboard. However, Intel revised the design guidelines for boards to be compatible with this quad core processor to decrease the signal impedance of the front side bus. This is different from the board specifications on the XPS 700. Also, Intel specifies that the Quad Core Extreme Processor needs 4 GTLREFs (GTLREF is reference voltage to the CPU front side bus to recognize signals as high or low for data coming to the bus) and the XPS 700 board has only two references. Intel?s revised design guidelines for the signal impedance change and the requirement for two additional GTLREFs to support its Quad Core processor caused Dell to make system-level board changes that have been implemented with the new XPS 710. With those changes, Intel?s new quad-core processors are fully supported on the XPS 710.
Here are the legal disclaimers:
Intel quad core processors may have stability/life expectancy issues when used on the XPS 700 because it lacks the required GTLREF support, or they may not work at all.
If you attempt to upgrade an XPS 700 with an Intel Quad Core Extreme Processor, we can?t guarantee that the Intel Quad Core Extreme Processor will work, nor will it provide support for quad core processor-related issues."
