I'd like to get memory speed information, but dmidecode -t memory says Speed: Unknown and lshw prints out string DMI and then does nothing until I kill it.

Is there other way to get this information? Or some magic parameters for lshw or dmidecode to force them to actualy do what they're supposed to?

root@server:~# dmidecode -t memory

# dmidecode 2.9

SMBIOS 2.5 present.

you could use dmesg to pull this type of information from the kernel

root@server ~]# dmesg |grep -i memory |grep core

dmesg is good for pulling any device info;
ie dmesg |grep -i scsi or dmesg |grep -i usb or just dmesg| more to see it all
