memory latency for ddr5 modules

hi there,

i want a simple memory latency output.

i found information regarding "decode-dimms" which should do what i want. but decode dimms complains about missing a modul :

"# decode-dimms
No EEPROM found, try loading the eeprom, at24 or ee1004 module"

i did have a look in my kernel config but could not find any module /eeprom.. any ideas ?

ryzen9-7950x with asrock 620 pro rs mainboard.

thanks !

Maybe you will need a working i2c and smbus (i2c needs pinctrl) ... have a look in chapter 2 of: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6

Maybe this can help also: https://forums.unraid.net/topic/96986-i2c-tools-decode-dimms-get-memory-timings-from-cli-solved/

(as far as I know EE1004 supports only ddr4)

(Maybe you will need also package i2c-tools)
