Re: "They certainly can make it work eventually, but who will make motherboards to work with the 800-MHz data transfer rate? Any takers?" I guess you'll have your answer later this month, if you can understand it that is.... EP

Ali, Is not the bus from CPU to chipset to RDRAM a known technology? Totally separate with it's own controller? and closely positioned to make them operate properly? Other I/O uses other parts of the chipset. Not being a chipset expert I am not sure where the Rambus problems have occurred. I have heard they are hard to make and test and have low yields. If operating RDRAMS are bought are they temperamental on mobos and erratic in their performance on the mobo? I can see that as line widths fall and cells get smaller they will be able to make cache style memory small enough that they can have a lot more on the CPU. Trouble is that kind of memory takes more cells and more wattage to operate and is inherently a consumer of more real estate. One day they will be able to make 64Meg of that kind of memory small enough and low enough in wattage with the speed to run at 800+ Mhz and rambus will not be needed. I suspect there are technical errors in this, such as they would run at 300 C or take 300 square MM, or some such or they would be doing it now in the research labs. Bill

They certainly can make it work eventually, but who will make motherboards to work with the 800-MHz data transfer rate? Any takers? I don't know if you intend to, buy you make it sound like there are 800 MHz signals that are required to be routed. I think we've been around on this before, but there are no 800 MHz signals. They data lines run at 400 MHz, producing 800 Megabits per second per line because there is data present on both edges of the data lines.
