The motherboard I have in this system is MSI K9AG Neo2-Digital. The system boots fine and I wanted to try memtest to see if there would be = errors. So I installed that /usr/ports/sysutils/memtest port and did=20 # memtest 2400 The output I got is: Continuing with unlocked memory; testing will be slower and less reliable. ....... pagesize 4096 pagesizemask is 0xfffffffffffff000 want 2400MB (2516582400 bytes) got=A0=A0 2400MB (2516582400 bytes), trying mlock .......failed for unknown= reason Loop 1: ..... In my /etc/rc/conf file I had added these lines in the past (when I had 4gb= RAM installed in it) sysctl -w kern.ipc.shmmax=3D1954311424 sysctl -w kern.ipc.shmall=3D238000 What is the case here? Why is memtest failing to use mlock? How can I event= ually make sure I can run memtest with 8000mb?=20 The purpose of this machine is that it will be used for a various data inte= nsive tasks where I need to be able to allocate as much memory possible. I = am running a postgresql database server on it as well to store my source da= ta. Brgds Dino =0A=0A=0A
