Hi folks,

I've bought a N100 days ago and I 've installed a 2gb module 667mhz to replace the samsung 1gb shipped with that.
I noticed that the samsung module is SN M470T2864QZ3-CF7 ( 1gb pc2-6400s ), so 800mhz frequency.
I did not know about this until today, I mean I did not know the pcb could support until 800mhz ram.
The 2gb module I bought is a 2GB DDR2 667MHz/PC2 5300 SODIMM corsair and it is well recognized by the OS :

The strange thing is the following:

Running an lshw -html this is an excerpt:

Is this funny or not?
However, how do I check the real speed of the ram by the OS and BIOS point of view?
In the Bios page there is any detail about the frequency, but I am pretty interested about Gnu/Linux Ubuntu.

According to According to http://en.wikipedia.org/wiki/DDR2_SDRAM

533mhz should be DDR2-1066

that is very strange indeed.

Windows with cpu-z :

pc2-5300 ( 333mhz ) that is ok when I use the 2gb module
