Hi h0db; Re: "Hey carl, what the heck is up with this? I thought Intel wasn't going to support PC1066 or the new RIMM4200 packaging."
Like I said before, I don't know for sure that Intel isn't going to support PC1066, but I'd be surprised if they do. The funny thing is that Intel has already validated 14 PC800 RIMMs for use with the 850E chipset, but still doesn't have any PC1066 or RIMM4200 Rambus parts validated:
RIMM Module System Validation Results
Intel web site, as of April 19, 2002
Intel® 820 chipset customer reference platform
Intel® 850 chipset platform (Intel® Desktop Board D850GB)
Intel® 850/Intel® 850E chipset platform

i850E supports PC800 RDRAM only?
Johan, AcesHardware, Febraury 27, 2002
Intel spokesmen have confirmed to us that the new 850-E chipset will feature a 533 MHz FSB but will support only PC800 RDRAM. According to Intel, PC1066 is too expensive right now, but Intel will keep evaluating the price/performance ratio of PC1066. Intel indicated that it is still possible that the i850E features PC1066 support when it will be launched (around June 2002).

We might compare this with Intel's timeline on support for DDR:
Intel's rollout timeline for DDR:
Nov 6, 2001 i845 DDR benchmarks appear #reply-16616216
Nov 19, 2001 Intel validates DDR SDRAM #reply-16680406
Dec 9, 2001 i845 DDR boards for sale #reply-16768504
Dec 12, 2001 Intel: "DDR shipping early" #reply-16782675
Dec 18, 2001 Still no DDR rollout #reply-16803693
Jan 3, 2002 Intel announces DDR #reply-16861225
This is a more complete explanation for why I'm not sure that Intel will "support" PC1066 with the 850E.

P.S. Thanks to elixe on the TMF Rambus thread for the note that Intel has validated PC800 but not PC1066 on the 850E:
