Hi Gene Parrott; Re "mixing manufacturers on a mobo." I am unaware of even any hints that that is a problem with the DDR rollout. You got a link? Problems with interoperability are more likely in the region of having a misinterpretation of the correct setting for one of the more obscure latencies. Or how the address lines are split between row and column. These are not serious noise problems with the bus (like the ones that canned the Rambus to SDRAM converters from Intel last year), but they are essentially infinite problems for mom and pop, which is why I say those guys would be better off with PC133 until they are ironed out. But it sure looks to me like Micron is holding back their PC2100 until something is changed. If I hear rumors that DDR is having "noise" [that means noise on the DDR memory bus, not noise on the Athlon / chipset bus, moron readers who don't know the difference] or "intersymbol interference" problems, the above does not apply, and that would mean that the DDR rollout is in serious trouble. (Just as RDRAM was in serious difficulty when it began generating reams of intersymbol interference problems. Intel had to tighten up board paramaters, and cut off the third RIMM socket.) In short, interoperability is not a serious show stopper. The industry rolls over those kind of problems with some regularity. What screws up the industry is noise and electrical interference problems, as well as emissions stuff. -- Carl
