4GB DIMMs are remarkably easy to find. Any decent retailer should have a selection. 2x2GB configs are the most common default config from everybody these days so 2x4GB is the most common upgrade. Only low-end machines have 4GB memory limits anymore, anything with a Core 2 or better processor will have an 8GB+ limit.
Also Win 7 x64 is pretty much the standard, outside of low-end machines and Netbooks nobody really ships 32 bit Windows anymore as it can't handle the default 4GB configurations. -Adam On Mon, Jun 14, 2010 at 2:59 PM, John Francis <[email protected]> wrote: > > The biggest drawback with laptops is the maximum memory configuration; > apart from that they are more than good enough for most purposes. > > My work machine (a Compaq 8710w) supposedly can support 4GB memory sticks, > so in theory can support 8GB of memory.
