Hi Jdaasoc; My guess is that the reason that Micron is not yet offering PC2100 DDR DIMMs for sale to the public is because they have had problems with some motherboard. Compaq is pretty careful about what they approve of, so if I had to hazard a guess, I would say that Micron sent them a set of a half dozen lot samples of PC2100, and then the Compaq guys abused the cr@p out of it, and found that a couple of them wouldn't work at 100 degrees C in a 30 g 100Hz noise acceleration environment after immersion for forty days and forty nights in boiling concentrated sulphuric acid. Or something like that. In other words, I'm guessing that the reason that we haven't heard exactly which DDR DIMMs are incompatible with which DDR motherboards is because the incompatible parts haven't been released for sale. As long as it stays in the family (i.e. not sold to retail), the motherboard and memory makers aren't going to go bragging about their problems. But I would expect that, as with every new memory before it, there will be compatiblitiy issues show up in products sold to customers. (Which is why I suggest waiting six months.) Compaq was asking a lot of money for upgrading a 256MB DDR machine to 512MB, and that (retail) business has to be attractive to Crucial. So I have to bet that Micron is having a problem proving to Compaq that their stuff works in that machine. Kind of makes me wonder who Compaq is getting their DIMMs from. Surely it must have been specified in a press release. But this is all totally my speculation, I really don't know. -- Carl

John, There was a note on the OR840 motherboard documentation on INtel web site stating that certain combinations of RIMMs did not work. I think it was combining a 64 MB RIMM in first slot and a 32 MB RIMM in second slot. No fix was mentioned as being in the works and the OR840 is not a big mover for Intel anymore. If you check some of the PDF files at Intel you will be able to confirm it. This still sounds like a generic chipset bug to me. Is this all there was? Do you remember seeing anything else about problems with specific combinations from specific manufacturers? Or something like "don't use RIMMs from company XYZ in systems made by company ABC? Thanks, Dave
