ECC RAM



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Dear List,

I have been running servers for years with ECC RAM, but only realised today that linux doesn't seem to spit out any messages when something goes wrong.

I have noticed that in the BIOS for our SuperMicro servers we can set the ECC notifications to NMI, SMI or SMC. As of 2.6.16, EDAC is included and seems to provide support for checking ECC RAM.

What should I set the bios to - leave it set as SMI, or should I change this to NMI?

If I set it to NMI, does the kernel provide error messages without using the EDAC driver?

Questions questions questions...

Thanks

Andrew
