|
|
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 ! _________________ I do not have a Superman complex, for I am God not Superman

thanks, i got further...
modprobe eeprom still prints Code: | modprobe eeprom
modprobe: FATAL: Module eeprom not found in directory /lib/modules/6.8.2-gentoo |
but i could load at24 and ee1004. but decode-dimms still does not print anything useful : Code: | decode-dimms version 4.3

Number of SDRAM DIMMs detected and decoded: 0

my kernel config is as follows : Code: | # EEPROM support
#
CONFIG_EEPROM_AT24=m
CONFIG_EEPROM_MAX6875=m
CONFIG_EEPROM_93CX6=m
CONFIG_EEPROM_IDT_89HPESX=m
CONFIG_EEPROM_EE1004=m
# end of EEPROM support | do i need more modules?
any ideas how to get modules that support ddr5 chipsets ? _________________ I do not have a Superman complex, for I am God not Superman

I still dont know howto show my ddr5 memory latency.
I got i2c-tools but "decode-dimms" reports : Code: | # decode-dimms
# decode-dimms version 4.3

Number of SDRAM DIMMs detected and decoded: 0 | after I load at24 manually. The eeprom modules does not load Code: | # modprobe eeprom
modprobe: FATAL: Module eeprom not found in directory /lib/modules/6.9.3-gentoo |
any tipps ? _________________ I do not have a Superman complex, for I am God not Superman

Mgiese,
What does tell?
Its very easy to run one kernel and build another. _________________ Regards,

Mgiese,
So far, so good.
/usr/src/linux is a symbolic link. What does it point to? _________________ Regards,

Mgiese,
TBH I dont know a module EEPROM of the kernel ... Yes, I have searched for it - I only found: at24, at25 and ee1004 (and some unimportant) ... Maybe the errror message is misleading (and means "one of the eeprom modules is missing") ... OR ... there used to be a module called EEPROM in an old kernel version ?
Have you really all 3 enabled (at25 you will get only if you have enabled SPI):
Code: | Device Drivers --->
Misc devices --->
EEPROM support --->
[*] I2C EEPROMs / RAMs / ROMs from most vendors
[*] SPI EEPROMs (FRAMs) from most vendors
[*] SPD EEPROMs on DDR4 memory modules |
I'm afraid I can't help you any more because I'm at the end of my knowledge here. _________________ https://wiki.gentoo.org/wiki/User:Pietinger |

I enabled all modules as "in kernel" in Code: | Device Drivers --->
Misc devices --->
EEPROM support ---> |
Maybe EEPROM is an old module after all. Nonetheless the output of decode-dimms is still zero. Code: | # decode-dimms
# decode-dimms version 4.3

Surely there must be a way to show DDR5 latency _________________ I do not have a Superman complex, for I am God not Superman
