jim: I was wondering why no major Taiwanese mobo vendor has released a 840 chipset based RDRAM enabled product for the white box market. Does anyone have any information on status of Camino2 or updated 840 chipset as next RDRAM based computer generation. Or do we go directly to Tehama/Williamette in the fall for round two of RDRAM wars. john

jk, One reason Intel is in the motherboard business is so they won't be saddled with the problem of a lot flaky motherboards from third party manufacturers. Intel performance as far as quality and reliability of the chipsets and motherboards has suffered since Intel jumped on the RMBS bandwagon. It takes a a certain level of engineering expertise to design PC boards that work well at hundreds and thousands of MHZ. The problem described in the pdf document has nothing to do with speed of the processor, FSB, multiplier, or any combination of the three. The processors have been faster than the memories for some time and now the memories are catching up. the ratio between the speed of the CPU and memory used to be 1:1. It has been going up since then, not down. Memory is not catching up. It's falling behind. We will see more of this type of problem as clock speeds rise. I hope we will not. Joe

jim kelley, <One reason Intel is in the motherboard business is so they won't be saddled with the problem of a lot flaky motherboards from third party manufacturers.> Simply brilliant! So, now they want to be in the saddle with the same everlasting RMAbus problem! ftp://download.intel.com/support/motherboards/workstation/or840/ download 24528806.pdf Little analysis, especially for you, jim_kelley: 1. The "errata" 28 says: "In system configurations with a single 4 or 6 device PC800 RIMM installed in each channel, the system may experience memory errors" "...observed behavior can range from being completely transparent to the user to causing system hangs" "Workaround: Configure systems with PC800 RIMMs with 8 or more devices... or use PC600 RIMMs" Sounds like "Return Merchandise Authorization required", isn't it? As I said, RMAbus :) :) 2. The errata 28 was added on Jan 12,2000, see the "Revision History" page (iv). However, the errata 29, or next to 28, was made public on December 8, 1999. Therefore the errata 28 apparently is in the work for HALF a Year at least. Now, most of the 40 "erratas" except 10 were fixed, yet the number 28 is still pending the fix. Why it lasts so long, and no fix yet? Probably because "Rambus ensures all Partners' chips, modules, connectors interoperate compatibly"? Or you have another, even more brilliant explanation?
