Which chipsets can handle ECC Registered DDR memory

[Shippy]

Are there any Pentium IV socket 478 chipsets where I can use this memory? Right now I'm using them with a Tyan Tiger MPX motherboard, but they can only be recognized at 100MHZ so my dual XP's 1900+ are running at 1200MHZ each. I'm told that i7500 & i7501 chipsets (Xeon) can use these but I don't really want to build anohter dual xeon system.

So are there any other chipsets that can utilize this memory?

Some of the early A64 enthusiast boards use registered, since the FX-51 was only made for socket 940. You could pick up an Opteron 140 or 142 for $160 or a 144 for $175 at Monarch.

Oh, forgot the board. There's a list of Opteron boards at AMDboard (watch out, the page is sometimes FUBAR).
