I would personally always use ECC memory. Here's D. J. Bernstein's recommendation on the subject: http://cr.yp.to/hardware/ecc.html ECC detection and correction usually has to be enabled in the BIOS and is performed by the hardware. Linux kernel from 2.6.16 includes the EDAC project (http://bluesmoke.sourceforge.net/) code to report memory errors and corrections to syslog for supported motherboard chip sets. Also see Documentation/drivers/edac/edac.txt in the Linux kernel source tree. Thanks, Mike
