intel atom n450 and N455 are exactly same except for support for DDR3 in N455. And since N455 was released after N450 (Previous quarter), the netbooks carrying the N455 are usually better. Whereas the N475 is a faster processor it also doesnt add much performance boost to be considered as an major upgrade and in terms of Price vs Performance N455 is better than N475 . And it is newer model than N450, it takes this battle easily.

I have a toshiba netbook with an Atom N455. I want to upgrade the RAM to 4GB DDR3 and I’m wondering if the processor could handle it ? ( I know I have to upgrade windows starter too 🙂 )
same question. will the n475 1.86GHz it handle 4gb ram
…have couple of acer netbooks…
…the N450 will NOT step down a 800mhz DDR2 memory stick to 667mhz…2 gigs at 667 is it and there are no options in bios to change things. The 667mhz sticks are getting hard to find…most shops seem to have only the 800mhz sticks.
Oddly though, the much older N270 in my now 2 or 3 year old Aspire One netbook seems to use the newer 800mhz two gig memory sticks just fine.
Had to swap the 667mhz memory sticks from my old Acer to the new one to make things work.. so beware and make sure you find a 667mhz stick if you do a memory upgrade…shops won’t always take em back if you get the wrong one.
hi.!
i have Intel(R) Atom(TM) CPU N450 @ 1,66GHz 1,67Ghz and a 1gb of ram
i want to upgrade my ram to 4gb 800MHz it is compatible to my lenovo ideapad s10-3 or not?
