Btw, anyone know how to enable ECC support in Linux/SuSE 9.0?

Enable it in the BIOS and then load the ecc.o module...

You don't need ecc.o on Opteron. It's handled by the normal machine check handler. -Andi

Huh. So when I enable ECC in the BIOS for my HDAMB, I get a ton of options to choose from. It there a guide somewhere where one can get a summary of the proper way to set up my long list of ECC options? Forgive me for being dense, but

If there was a single proper way there wouldn't be any options, no? It really depends on how your motherboard is set up, what revision of the CPU you run, what and how many DIMMs you use and where you put them. Also some kernels assumed that the BIOS would enable the MCE error reporting, which some newer ones don't.

the HDAMB documentation from rioworks offers no guidance at all here, let along Linux specific recommendations.

All the glory details are in the BIOS&Kernel developers guide from the AMD website (but read the Specification update too) If you don't want to go that low level: A reasonable default setting is probably ECC on, scrubber on, chipkill off. -Andi
