NB520 - Upgrade to 4GB RAM

I gave a try to upgading NB520 memory to 4GB (I read the manual, I know it says maximun 2GB), just in case.
Sorry to say it didn't boot. It is not a materof windows 32bit or 64bit because BIOS (1.5 and 1.9) got stuck before passing control to windows.
Module used was KINGSTON 1066 CL7:
DDR3-1066
KVR1066D3S7/4G

I read somewhere somebody was using 4GB on a NB.
Did someone tried 4GB?. Is it really working ?
Any BIOS trick for making it work?

The Intel Atom CPU is not capable of 4GB, there is no way around it.

I think you were thinking of the AMD Hudson platform (NB550D) which may be capable of 4GB.

Thanks Akuma.
Actually it is all very confusing to me, while Intel specs say:
Max Memory Size 2GB (dependent on memory type)

http://ark.intel.com/Product.aspx?id=55637

(Don't know what they mean by "depending on memory type")

Seamicro produces a multiprocessor based on N570 where each one can handle 4GB.

That's why i thought it's a toshiba BIOS limitation.
Or perhaps Intel makes several product lines of N570.
