No that doesn't work at all!
I would recommend anyone disregards these instructions. They make no sense.
I followed the instructions but they failed at Startup > Advanced. There is no Advanced in the Startup tab.
I 'did' find an Advanced option in the Boot tab, but why you would limit the number of processors used at boot up defeats me.
Why you would reduce the available amount of RAM mystifies me.
Using those options are for diagnostic purposes only, so my advice;
Do Not Follow The Advice Above.
