I love my 8KTA3, but this is a weak point for the board. It is strange, though--one of the reasons EPoX is able to make such a great enthusiast board is because they do not have to limit their designs for OEM's and newbies. Thus, it seems logical that EPoX would allow unrestricted control over memory timings, possible instability be damned! I think that those who are sophisticated enough to be dealing with memory timings also know enough to check memory timings as a possible source of instability, should it arise.
I hope that EPoX will provide a BIOS to rememdy this, even if in the form of an alternative enthusiast BIOS.
