decode-dimms
decode and display RAM SPD EEPROM information
TLDR
Display DIMM information
$ decode-dimms
Display DIMMs side-by-side for comparison$ decode-dimms --side-by-side
Decode even if checksum fails$ decode-dimms -c
Read from hexdump files instead of live system$ decode-dimms -x
Display help$ decode-dimms -h
SYNOPSIS
decode-dimms [options]
DESCRIPTION
decode-dimms decodes and displays information stored in the SPD (Serial Presence Detect) EEPROM of RAM modules. This includes memory type, speed, manufacturer, size, and timing information.Useful for identifying installed memory specifications and verifying RAM compatibility.
PARAMETERS
-h, --help
Display usage summary.-c, --checksum
Decode completely even if checksum fails.-f, --format
Print output in HTML format.-b, --bodyonly
Don't print HTML header (useful for postprocessing).--side-by-side
Display all DIMMs side-by-side if possible.-x
Read data from hexdump files instead of the running system.-X
Same as -x but treat multibyte hex data as little endian.
