Hi Dave B; Re: "I didn't see anything in your 840 list (I haven't checked the 850 list yet) that says that some RIMMs will work and some won't work in specific motherboards."

Do you wish to assert that no such problems have ever happened with RDRAM? I'd love to prove you wrong on this, but I don't have the links available at this time. Please admit that it did occur, or give me a nice big target - a denial, preferably with an accompanying assertion that perfection is only available through subordination to the Borg, errr, Bus.

-- Carl

P.S. Please do remember that I don't make these sorts of statements casually, as you have seen many times in the past.

"There's no equivalent universal testing mechanism (or controller of the mechanism) for DDR."

That's where a big part of the RDRAM problem is!
The PC industry was growing so fast exactly because
there were no need for "equivalent" (or any other)
testing mechanism during the SDRAM era!
Mom-and-pop shops, or 50% of the
whole market, never tested anything, some just sold
boards, others just memories, and in 99% cases
everything worked just fine, no extra expenses for
"qualification" etc. After all, all this RAMBUS
qualification is bull - the stability of a system
eventually is defined by the whole thing together,
case airflow, board, power supply, board grounding,
cards compatibility with other local busses, etc.

I am confident the industry will achieve the same
level of interoperability with DDR as well. For the
SDRAM-100 it took about 2 years.
