No. Not since bigmem became the default for OpenBSD/amd64 on April 4, 2011, for inclusion in OpenBSD 5.0.
Prior to that, bigmem had about 3 years of testing by developers and interested users who were building custom kernels to enable it. Ref: http://cvsweb.openbsd.org/cgi-bin/cv...-cvsweb-markup Last edited by jggimi; 19th January 2015 at 05:48 PM. Reason: added link |

For i386, the addressable physical memory limit is 3 GB. The 4th GB, if installed, is not addressable. It is my understanding that PAE is used on OpenBSD with virtual address spaces (per process), not physical addressing.
