Maybe CC: arch@freebsd.org Perhaps should have done that when I started, but supplier assured me that the they just retired the boards with out any issues. Memtest86 found the faulty DIMM in 30 secs... Not sure if we could/want educate vm_mem_init() to actually detect this. It is still in the part where everthing is still running on the first CPU. Making things a bit easier to understand what is going on. Lets see if the box will run on 3 DIMMs for the rime being. Then figure out with DMIdecode what we need expand again. --WjW
