790 corruption issues?

VTT seems to play a major role in this, it seems that tweaking vtt/gtl makes it possible for some people to get their systems 100% stable or at least improve stability notably. According to one mainboard manufacturer the 790 chipset has very small tolerances when it comes to vtt, and hitting the sweet spot to get a system stable is not easy. Depending on what cpu you use, if its a quad or dualcore, and if its made in 65nm or 45nm, the vtt window shifts. this of course makes it very difficult if not impossible to program one "auto" setting in bios which just works with all cpus.

Saaya ,taking into account that this is true, and that is REALLY part of the problem, and that is almost impossible to program one "AUTO" setting in bios to work with all CPU´s. Woldn´t be a good idea for the motherboard manufacturers to release 2 or 3 bios each one with the AUTO settings optimized for a specific kind of CPU?
For example one BIOS for 45nm CPU´s and other for 65nm CPU´s or one BIOS for DUAL´s and another for QUAD´s or a combination of the two.
Althought this was never been done before, it could really help resolve a big part of the issue´s we hare having.
