A pair of four month old Opty 240's on a Tyan S2885 seems to
handle Corsair PC3200 ECC registered DIMMs just fine.

Running at full speed or underclocked? PC3200 will run fine at 166mhz.

Underclocked, AFAIK. I haven't run any memory test
utilities that report the RAM speed - care to suggest
something I can download and run ? Preferably
one that works with W2K or the 64 bit beta for XP
because I don't have a Linux password for that system.

Yup. DDR400 support is determined by the stepping of the processor,
not the speed. All chips that are stepping C0 or later, and that's
basically all of them these days, support DDR400.

Sweet. Thanks; I hadn't read that before, and am glad to know it. Are
motherboards up to date enough to run the DDR400 with the older chips?

They might need a BIOS update, but yeah, they should all be up to date
enough to run DDR400 on all current Opterons.

Thanks. We're still figuring things out, but we should be getting 4-5
desktops plus a dualie server in the next few months, and this makes the 146
a _lot_ more attractive for the desktops -- I'd be running on the assumption
that we had to jump to the 148 or 64FX to get the 400FSB.
