My unit has an SSD system disk and 12GB RAM. Will adding more RAM speed things up, or is some limit reached with extra RAM? Are you running 32bit or 64bit Windows 10 ? 32 bit is only able to use around 3.5 GB of ram. Can Windows 10 use PAE? Of course. It applies PAE to get NX (page table format quirk). They need a place to store the NX bit, to protect data segments from attempts to execute them (malware). The NX stands for "no execution of this segment", that's the basic idea. If the program counter wanders into such an area, there's an access violation or something. Chunks of memory are basically labeled according to their intended purpose (data or instructions). But the OS applies MS memory license of 4GB, so PAE cannot be used for its intended purpose. Even though PAE is perfectly willing to map stuff above 4GB, the MS memory license cuts it off at the knees. And that's where our 32-bit OS limitation comes from. A dude here, hacks Vista 32-bit, to run all 8GB of RAM on the guys machine. Just to show that PAE really works on Vista+. And this is done by defeating the memory license barrier. I had a Pentium 3 computer which had 8GB of RAM. It had 8 x 900 Mhz Pentium 3 CPUs and 4 x 15,000 RPM SCSI hard drives and ran Windows Server 2003. http://www.geoffchappell.com/notes/w...nse/memory.htm Paul |
