Dave: I gathered some recent links from Intel web site. Intel seems to be still committed to RDRAM except for server market. Registered PC133 DIMMs seems be better solution than RDRAM for several GB's of RAM that Rambus is not able to support at this time. Here are the links:developer.intel.com 6/29/99 "High-Performance Memory Implementations PC main memory design is becoming increasingly important for the overall system performance. We will show you how main memory affects system performance. You will get an update of the Intel PC SDRAM specs, including the Registered DIMM spec and the PC SGRAM spec for graphics. To prepare you for the transition to Direct RDAM in 1999, we will explain how the 1.6 GB/sec is achieved, and how to design your systems for Direct RDRAM. In addition we will provide you with an update on the status and plans of the DRAM industry."developer.intel.com 6/29/99 "Time for a Change: the new DRAM The address-multiplexed DRAM has been a staple of the computer industry for so long it is hard to imagine anything coming along to replace it, but that time has come. Intel has already announced that its next generation desktop microprocessors and chip sets will be designed to work with a new DRAM design called Rambus* DRAM Direct or RDRAM-D. Representing the second generation of Rambus memory designs, the new part offers very high memory bandwidth, low parts count, and greatly improved latency. While RDRAM-D is well suited to the desktop PC environment with its relatively small memory requirement, there is still work to be done to make it viable in servers. Given the potential cost penalty of using lower-volume, non-desktop DRAM designs for SHV servers, Intel has launched an intense effort to make RDRAM-D as attractive for servers as it is for PCs." developer.intel.com 7/1/99 Test Summaries Samsung & Hyundai kick ass with 144M RDRAM (makes 288 MB RIMM) ftp://download.intel.com/design/chipsets/memory/rimm_mts.pdf 6/25/99 Kingston has 288 MB RIMM Samsung has 144 MB RIMM ftp://download.intel.com/design/motherbd/ca/readme.txt 6/25/99 First document that I have seen that talks about 820 chipset and 82820 processor to I/O controller
