>>Q.) And also to confirm an earlier comment. You said the 820 chipset will support 133 Megahertz synchronous DRams. Is that correct?
paul's earlier comments were referring to 100 & 133 mhz front side bus.
i still stand by my comment: "intel has never said they will support pc133" but, paul's answer is confusing. someone needs to contact intel if still unsure.
i did a search on intel's web site and found not a single reference to pc133 but 35 references to pc100.
here's a good one i have not seen posted dated 5/15/99. note: the charts did not copy.

Direct RDRAM on its Way
By Jan Camps

Beginning mid 1999 mainstream desktop performance PCs will have a decided advantage: Direct RDRAM main memory technology—thanks to a successful industry effort spearheaded by Intel and Rambus Inc. In December 1996 Intel and Rambus Inc. began working together on a new memory technology for 1999 PC platforms. Recently Intel demonstrated this new Direct RDRAM memory technology at work in a PC platform—revealing that all of the pieces are coming together for the production ramp later this year. By successfully demonstrating the inter-operation of Direct RDRAM technology ingredients including Direct RDRAMs, RIMM modules, RIMM connectors, clock chips, and motherboard design and layout, Intel confirmed the reality of the 1999 advent of Direct RDRAM-based systems.
The Direct RDRAM program has hit all the major milestones and is on track for the 1999 product ramp. Later this year Intel will formally announce chipsets and PC platforms that will bring Direct RDRAM to the desktop, workstation, and server market segments. These chipsets will enable the processor, graphics and I/O to take full advantage of the higher Direct RDRAM performance. In fact, Direct RDRAM-based PCs will have two- to three-times as much memory bandwidth as the PC100 SDRAM-based systems on the market today. Direct RDRAM provides the bandwidth to allow applications to scale in performance with faster processors, graphics and I/O for years to come. With such compelling reasons to design with Direct RDRAM, expect platforms and memory to ramp at an accelerated pace.
Memory Bandwidth Comparison
Industry Support
Many DRAM vendors and memory module suppliers have announced the availability of Direct DRAM silicon and modules for system testing, and more are expected to make announcements in the future. Intel anticipates upwards of seven DRAM makers to have the 800-MHz and 600-MHz Direct RDRAM chips in volume production in the first half of this year, with numerous RIMM module vendors lending their support. The ever-increasing numbers of major DRAM vendors committed to this interface will allow customers to benefit from a number of supply sources.
Direct RDRAM Number of Vendors in Production
To further facilitate the development of RIMM modules, Intel and Rambus will provide additional technical design seminars in the Asia-Pacific region at the end of January. Design packages for RIMM modules will be available from the Intel and Rambus Web sites at that time. Intel will demo the Direct RDRAM-based system at the upcoming Intel Developer Forum, where developers may also receive additional information and training.
Look for more RDRAM news in upcoming issues of Platform Solutions, and get ready for the transition to this high-speed memory interface.
