Ondanks de problemen rond de produktie van Rambus geheugens en de enorme afgang die Intel met het i820 Rambus fiasco beleefde, is Rambus door Intel toch uitverkozen als geheugen architectuur voor de Willamette processor. Intel ontwikkelt voor de Willamette een nieuwe chipset met de naam 'Tehema', die volgens bronnen van EBN Online in feite een upgrade is van de huidige i840 chipset met dual channel Rambus support:
Intel Corp. is making Direct Rambus DRAM the key memory for its next-generation Willamette processor, which will be spotlighted next week at the Intel Developers' Forum.[...] Willamette will use an upcoming Intel Tehama chipset, which sources say is an upgrade of the dual-channel Direct Rambus-compatible Intel 840 chipset. Tehama picks up almost all of the north bridge and south bridge functions included in the 840, but interfaces with the new processor bus.
[...] While Rambus is the memory interface of choice for the Willamette, sources said Intel could fall back to double-data-rate (DDR) SDRAM if necessary. It is uncertain whether Intel will introduce the Willamette and Tehama with the Memory Conversion Hub (formerly known as the Memory Transfer Hub) motherboard option offered with the Intel 820, which enables the use of either Direct Rambus or SDRAM.
