e_f, well then that settles it for sure, it MUST be the SPP...

It doesn't happen and system can't correct or control the errors caused by such situation, sending false commands and data to a HDD and corrupting it.
what? that doesnt make any sense, why would you implement a mechanism to "check" if a certain speed is stable and only then allowing the system to boot? this doesnt really sound right... are you sure thats how other chipset mfgs do it?

Now they need to find a better solution, either in BIOS, in SPP driver or in the worst case - in hardware (SPP). They are working on it, as far as we all know, but why should we suffer because of such situation - it is a question.
well this sounds like first you release a bios thats tweaked for performance, so then all the reviews look great and some people post great results, but then you release a new bios that actually makes all boards stable but performance sucks... so basically they are selling 2 types of 790 ultra boards, some that can run stable with a tightly tweaked bios and some that cant... come on, wth is that? i honestly pray its not like that...

yeah, totally agree... but then again, some boards seem to work perfectly fine even with tweaked bios and high clocks...

i keep hearing about different chipset revisions... b2 and c0?
so the older rev is actually better?
what revisions do you guys have?
c0 seems to be really crappy while b2 steppings seem to work fine?
are there c1 and b1 revisions too?
