Subject: Adjusting the amount of RAM being used in the MP7,1
If one wishes to perform various tests using different amounts of RAM physically installed in the MP7,1 the Terminal command sudo nvram boot-args="maxmem=<size>" can be used.
For example say you have 384 GB installed as 12x 32 GB R-DIMMs and you want to use only 32 GB, then using
sudo nvram boot-args="maxmem=32768"
and then rebooting, can be used.
However, I'm unsure just how much of each R-DIMM (and memory channels) is used to deliver the 32 GB. Does any one know how the 32 GB is distributed amongst the R-DIMMs in this case ? Thanks.
