This is the vibrant and exciting story of how Jonathan Morrison installed 1.5 terabytes of RAM on his Mac Pro “to see what happened.” The test was to open thousands of tabs in Chrome, a legendary application for its inexplicable gluttony with RAM, and put a script. The result… I don’t want to spoil, because it’s worth seeing (and things are learned). Also the beginning of the video is very funny.
The first thing is that installing so much RAM on a Mac Pro is possible but not necessarily recommended: there are no obvious applications for such a large capacity and although working in RAM is certainly faster than working on an SSD, the current ones are so fast (and improve every bit ) that there is hardly any difference. In price instead, the trigger thing: the 32 GB modules cost about $200. You have to be willing to drop about $9,600 for taking pleasure. And that is at non-Apple prices. The dive if you buy it directly with the apple is 30,000 euros of fleece. Hey, nobody said it was cheap.
The fact is that the good man puts a script to open “real” web page tabs (nothing from Apple.com or blank windows) and the account starts to go up: 500, 1,000, 2,000, 3,000… So up to 6,000. Chrome is able to open more than 6,000 tabs using just over 1.4 TB of RAM; In fact, apart from Chrome, Final Cut Pro and other apps are just open, just to get in the way. The Mac spent 22 hours working non-stop and without hanging – a merit for the macOS – with the CPU with the turbo butt (3.2 GHz) – hardware merit – until it reaches the critical moment in which the RAM is about to run out and come to open tabs and more tabs … [See video from 04:20.]
Other applications for a cucumber piece of this caliber are to create a RAM disk in which you can copy for example Final Cut Pro complete (other traders) and edit large videos and hundreds of clips directly in RAM, which although going pretty well is not something especially much faster, and especially music applications. When everything is in RAM its speed can be measured, which turns out to be about 4,000-4,500 MB / s read / write . Apparently that is useful and saves time loading RAM libraries of hundreds of GB like those used by some musicians to create their compositions.
