I have revision 2.0 of this 870A-UD3 board, which, according to this page "deliver[s] native support for DDR3 memory up to 1866":
Initially, I had 1333, 9-9-9-24, 1.5v ram from another vendor, but it wouldn't run stably at that spec without 1.65v (although after reading some of your posts here, I'm beginning to realize that 1.65v is pretty normative for stability for > 1333mhz DDR3).
To be cautious, I'd prefer to get something else now. Which Mushkin RAM modules would you expect to run fastest and most stably on this new AM3 motherboard? Btw, I'm not in a critical rush as I have another system functioning well that I'm currently using, therefore, if there is something you think best that isn't yet released but will be soon, don't hesitate to mention that too, if applicable to 870A-UD3. I'm more concerned with rock solid stability and speed than cost at this point. The current CPU is a Phenom II X2 555 Callisto unlocked to a Phenom X4 955 Deneb.
Thanks very kindly in advance, Anton.
