Sorry for my ignorance. I know very well (more than) in many aspects INTEL

This is one missing info. Because, so far, if you did not know, there are
two types of 32-bit kernels: normal 32 bit, and PAE 32 bit. But, in
contrary, x86_64 has only one type of kernel sup

Yes, this statement is very blurry - I thought about artificial memory
limitations like ones in C2000 Atom server series - there are almost
identical models (C2530 and C2550 for ex

Of course - I did not bring up chipsets ;) I am also not
Hello Stefan,
Let me ask you for some other stuff, since I would like to put what I wrote

But CPUs we are looking at *are* actually different - scale-down could
mean an exposure of a previously unaccounted design issue which
actually prevented 32nm CPU 'upgrade' to work r

Please don't spread FUD if you don't know what you are talking about.

Hello Stefan,
In addition what Charlotte wrote to you, I would advise you the following
(as general approach for mem problems):
[1] Please, for testing the memory, use secondary Coreboot payload called
MEMTEST:
[user@localhost coreboot]$ cat .config | grep MEMTEST
CONFIG_MEMTEST_SECONDARY_PAYLOAD=
Addressing over 8G is not supported by the chipset used on nehalem thinkpad
laptops (X201)
Stupid limitation, but it is not the CPU fault.

Hi Vladimir,
since you have REed the raminit for Nehalem I'd like you to ask if you
have any knowledge, information or pointers about using 8 GB DIMMs with
it or even using more than 8 GB in total. In my case it is about an
Arrandale i5-520M (in a Thinkpad 410s).
I know that an i7-820QM (Clarksfi
