From the article
"Fred seems to have found a way to check the memory bus width :
I think I have something straightforward :
in a terminal window:
ioreg -p IODeviceTree -n memory -S | grep "ram-bus-width"
on an iMac G5 with two identical RAM sticks, it returns :
"ram-bus-width"= <00000080>
Of course this value is in hex, which translates into 128
I didn't have the opportunity to test a different configuration, but I would be quite surprised to see anything else than :
"ram-bus-width"= <00000040>"
I just ran this and my results translate to 128 (assuming the above to be correct). I have 2 sticks of identically matched 512.
Try it and post your results. Hopefully someone with only one stick or mismatched sets will chime in.
