Mixing ECC and non-ECC

[MikeHiow]

Someone must have tried it?

I have an ML110 G3 here that runs most of my dev stuff. I have no need for ECC ram and have a spare 1GB module (non-ECC) laying around, which would be a useful upgrade.

The current ram appears to be unbuffered items

I've seen mixed reports some say it works and some say it doesn't, only one way to find out plug it in and see, it's not like it will do any serious damage if it doesn't work.

I would normally do this, but a bug with GRUB in an earlier Ubuntu and the lack of a monitor means I wouldn't find out if it's worked or not for at least half an hour, and this machine routes all of my internet traffic.

I guess I'll just have to suck it and see.
