On of my system with 8G of RAM running 7.0R amd64, dmesg shows memory usage as: usable memory = 8576397312 (8179 MB) avail memory = 8289071104 (7905 MB) If I set hw.physmem tunable to 8g, dmesg shows the following usable memory = 7771095040 (7411 MB) avail memory = 7507386368 (7159 MB) If I set hw.physmem to 8950M usable memory = 8565911552 (8169 MB) avail memory = 8278892544 (7895 MB) if I set hw.physmem to 8999M usable memory = 8576397312 (8179 MB) avail memory = 8289071104 (7905 MB) Is this expected behavior? How do I increase or decrease physical memory size by 1MB? Thanks, -ManjunathReceived on Tue Jul 22 2008 - 20:59:58 UTC
