I can see my memory speed, such as DDR3-1600, with CPU-X, but it doesn't display the full timing values in the usual format like 9-9-9-24. Is there a Linux program or command that can show the RAM timings?

CPU-Z can display timings, but it’s a Windows utility, so it isn’t a practical option on Linux.
Check your BIOS/UEFI first, since it usually lists the configured memory timings. On Linux, hardinfo2 may also report them, and decode-dimms can read the timing information stored in the RAM module’s SPD data.
If decode-dimms reports that no EEPROM was found, the required SPD-related kernel module may not be loaded. It may suggest loading modules such as at24 or ee1004; hardware or firmware limitations can also prevent the SPD data from being read.
Thanks—that’s helpful. I’m specifically looking for a Linux-native option, so I’ll check the BIOS and try hardinfo2 or decode-dimms.
