The interesting part of this "RAM crisis" is similar to other fields where a problem results multiple parties looking for alternative solutions.This yields for exciting ideas or workarounds that might result a post-crisis memory boom (hopefully) also for local machines.1. Lowest, Apple is evaluating new Chinese manufacturer which means change of supply demand if indeed it has reasonable QA.

Companies tries to workaround performance - suddenly single channel is 'ok' ? :) (<a href="https://www.gigabyte.com/press/news/2403" rel="nofollow">https://www.gigabyte.com/press/news/2403</a>)
