Intel Atom N455 Go to product viewer dialog for this item. is a single-core "Pineview" netbook processor that officially has a hard memory cap of 2GB. While the N455 architecture is 64-bit capable, its integrated memory controller was designed for ultra-low power consumption and generally does not recognize more than 2GB of RAM. The 4GB RAM Dilemma Summary: A low-power netbook-era setup — good for
The idea of running 4GB of RAM on an N455 system is a common topic in modding communities because the Intel NM10 Express Chipset (often paired with this CPU) theoretically supports 4GB, leading some to hope they can bypass the CPU's own limit.
Before talking about RAM, we must understand the CPU bottleneck. The Atom N455 is a 45nm, single-core processor with Hyper-Threading (appearing as two logical cores). It runs at a fixed 1.66 GHz with a 512KB L2 cache.
