Why can I not find my RAM specs through software?

I wanted to find the RAM specs such as frequency and interleaving. Here's a few things I tried:
Code:username@username-T400:~$ sudo lshw -c memory
[sudo] password for username:
*-firmware

vendor: coreboot
physical id: 0

01: None 00.0: 10102 Main Memory
[Created at memory.74]
Unique ID: rdCR.CxwsZFjVASF
Hardware Class: memory
Model: "Main Memory"
Memory Range: 0x00000000-0x1d9d69fff (rw)
Memory Size: 7 GB + 512 MB
Config Status: cfg=new, avail=yes, need=no, active=unknownCode:username@username-T400:~$ sudo dmidecode -t 17
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.My gut tells me it's the fault of Libreboot. If so, I'd enjoy an explanation as my search engine skills fail me.
Ended up opening the laptop and looking at the stickers on the RAM.
