This article wasn't about how to fix RAM to work on your system, it was to discuss what Intel officially supports. Not everyone will know how to lower the voltage and clock settings on their RAM, and not all RAM will operate at lower voltages even if you lower the clock speed. That is something users will need to test for themselves on a case by case basis.What this article fails to mention is that most kits of DDR3 rated at 1.5V can still run at 1.35V. Just at lower clocks.
You're advising people to spend money on DDR4 when they can most likely continue to use their DDR3 memory. That's simply bad advice.So if you don't have DDR3L on hand, you are probably better off to go ahead and spring for the more expensive DDR4.
