I've total 8 GB RAM installed in my dual boot Ubuntu Linux 8.10 (32 bit) version HP workstation. But free -m command only shows 3291 (3G) memory. How do I use 8GB RAM under Ubuntu Linux?]]> http://www.cyberciti.biz/faq/ubuntu-linux-4gb-ram-limitation-solution/feed/ 107 http://www.cyberciti.biz/faq/linux-find-out-cpu-36-bit-physicaladdressing-or-not/ http://www.cyberciti.biz/faq/linux-find-out-cpu-36-bit-physicaladdressing-or-not/#comments Sun, 23 Nov 2008 11:03:41 +0000 Vivek Gite http://www.cyberciti.biz/faq/?p=2569 Q. Physical Address Extension (PAE) refers to a feature of x86 and x86-64 processors that allows more than 4G bytes of physical memory to be used in 32-bit systems. The x86 architecture presently uses only 36 bits out of 52 bits possible. On x86-64 processors, PAE is obligatory in native long mode; currently 40 bits are used out of 52 bits possible. How do I find out if my Linux kernel supports 36-bit or more physical addressing?]]> http://www.cyberciti.biz/faq/linux-find-out-cpu-36-bit-physicaladdressing-or-not/feed/ 3
