Ali, However, the RAMBUS timing requires about 100-150 picosecond time budget for egde skews, which means that the board designer must handle tracing/material properties up to 10-20GHz range (accounting for edge rise/fall times of 30-50ps). Are you telling me that there are signals in the Rambus technology that are physicallyin the 30-50 ps realm? Can you show me any pictures of such rise/fall times as 30-50 ps, and that's 10 to 90%, or 20 to 80, and not 48 to 53% or something? If you're telling me that those types of picosecond rise/fall times are what are required to make Rambus work, you are way out in left field without a glove, in fact, over the wall on that one. I think that it is technically illiterate managers like yourself who dragged Intel into premature switch into techology that current MB makers simply cannot afford. Sounds like you think all managers are technically incompetent, like the pointy haired one in Dilbert. Well you have another think coming, bitter man.

Ali, This may in fact be the reason why the modules are hard to make in volume. It will take far more stringent control over the board manufacturing details to 'guard' those pico-second signals from assorted variations, and that is just the modules, same thing on the mobos, I expect. These will all combine to make a "tax" on Rambus that will favor the 133 stuff. They may have a 50% yield on module making, thus doubling the cost of the ones that make it. Reworking the failed ones will alleviate this, but it has it's cost as well and they will still have the 50% failure rate when the stripped memory is replanted, or more? I expect that as time goes by they will be able to control more of these problems and should get up to the typical 99% yield that standard memory module makers have with pretested boards and ram chips.

Hi Ali Chen; Re: I think that it is technically illiterate managers like yourself who dragged Intel into premature switch into techology that current MB makers simply cannot afford. LOL! These are exactly the guys who think that they know more than their engineers, enough to overrule them on technical issues, but got all their knowledge on the subject from an overhead slide projection. These are the guys who sent the Challenger off on its last mission. I should write up a complete post on what engineers really think about their management, particularly how one can tell if one is a Dilbert boss. -- Carl
