Skeeter, there's the Nvidia nForce, which is allegedly also developed for the P4, but Intel won't license them for whatever reason. It's not entirely clear that the P4 wouldn't work ok with single channel DDR. But the P4 is set up to be a bandwidth pig via both a big cache line and a lot of prefetching. The 128 byte cache line would probably be a good match for single channel DDR, but the prefetching may well kill it. There was this McComas piece a little while back showing that in one SPEC program anyway, the P4 used 4x the memory bandwidth of the PIII to get a monumental 10% gain in performance, or something like that. And Intel was bragging about it! Of course, the P4's piggishness with memory bandwidth may present other problems, as in it's not clear that it works very well in multiprocessors. See extremetech.com for a recent writeup.
