Followup: 'Underclocking' and mixing ECC/non-ECC Rambus

Thanks for mentioning this, Paul. A convincing argument.
I decided to keep existing hardware and bump up to a 2.8Ghz
400FSB Northwood. It's--running fine on P4T-E beta bios v 1008.4.
It's not a quantum speedup, but it's noticeable. I didn't need that
much more speed on this particular system anyway.,

Now I've got to figure out whether it's worthwhile to jump up from
1.5GB Rambus to 2GB. Of course I'd need to replace two
256K RDRAMs with 512's, so that extra 500KB will cost as much
as the CPU upgrade..

Here's something interesting: I was going to inquire about mixing
the ECC and non-ECC Rambus. Then I checked the part numbers
on the existing sticks -- they're already mixed! The 256's are
non-ECC, the 512's are ECC. (Yep, I just kinda threw 'em in there)

This system seems to run stable until really pushed, and usually
the thing that puts it over the top (reboots) is an app that generates
sound (Winamp, PowerDVD, etc). At this point I suspect the sound
drivers.

Has anyone else used mixed ECC/non-ECC? Any known problems?
