The laptop has an Intel Core CPU that supports 36 bit physical addresses (via larger memory pages), so – practically – it can address up to 64Gb of RAM. The constraint is the Intel chipset.
- zozbot234 3y agoPAE is a hack, you're still not able to use more than 2GB (or 3GB if you're lucky) of address space in a single process. Like it or not, we're at a point where that might not even be enough to browse a single webpage (if that webpage is a horribly bloated SPA). 64bit compute is inevitable.
- inkyoto 3y agoMy point did not pertain to aesthetic qualities of PAE but rather to a limitation of Intel CPU chipsets that imposed a maximum memory constraint (either out of marketing microsegmentation or engineering reasons), the practice that has persisted for years onwards and upwards, and was likely the catalyst for the PC laptop vendors to start soldering the memory chips on. Lastly, running 3Gb processes (which Linux supported and Windows did not) on a ultra-portable laptop was not really a thing in 2008, and who was going to win the 64-bit x86 flavour battle (AMD or Intel) had not become clear yet.
