Rasdaemon is a RAS (Reliability, Availability and Serviceability) logging tool. It records memory errors, using the EDAC tracing events. EDAC is a Linux kernel subsystem with handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm also exists.

rasdaemon: labels/intel add vendor and DQ57TM model #142

For the Intel Corporation DQ57TM motherboard, booted in UEFI showed the right locations with --guess-labels but still need the following labels/intel addition for showing correct DIMM numbers.

For slot2 and channel2 shown by layout no resembling DIMM locations are situated on the motherboard.

$ sudo dmesg | grep DMI | grep DQ57TM

The DIMM labels and slot coloring on the motherboard from left to right is CHANNEL A DIMM 1(black), CHANNEL A DIMM 0(blue), CHANNEL B DIMM 1(black), CHANNEL B DIMM 0(blue) may sound confusing but that's what it is.
