Module size is actually shown properly.

Speed is indeed missing. Please provide the output of
# dmidecode -t 6 -u
for confirmation, but most likely the information was not set by the
BIOS so there's nothing dmidecode can do about it.

Also check if you have type 17 records later on, as type 6 was
deprecated long ago. You may get more information from type 17 if
present.
