DDR4 vs DDR3 with Linus

DDR4 is the latest evolutionary step forward for synchronous DRAM   the memory technology that youll find in most of the electronic devices you own like your desktop or notebook computer or game console,  and even some very important ones you dont own like the servers that power websites  and services like Facebook or Dropbox. Physically a DDR4 module probably wont look that special to you... However, there are some subtle differences.  DDR4 RAM is not backwards compatible with DDR3 motherboards and vice versa, so the notch has been moved to prevent accidental insertion of the wrong type of memory.

Now instead of 240 pins, each module features 288 pins. And finally to improve strength and electrical contact theres a slight curve in the shape of the bottom of the PCB. So nothing ground breaking... No, its whats UNDER the hood thats interesting.

So what does this new fourth generation DDR bring that the previous one  DDR3  didnt? Actually more than youd think. First up is improved SPEED. Thanks for that. DDR4 STARTS at 2133MHz  which would be fairly high end for DDR3  and has planned speed increases that could take it well beyond 3200MHz! And this is while requiring only 1.2V per module.

Which leads to benefit number two  power savings. DDR4 is more efficient that DDR3, consuming up to 40% less power. This is something that might not seem like a big deal in your desktop PC, but lets talk next time your notebook shuts down due to low battery when you were 4 seconds from submitting that homework assignment! When it comes to mobile devices, every little bit counts! Speaking of bits  memory capacity is poised to go through the roof  due to DDR4s support for higher density chips and stacking technologies that will allow for single memory modules with capacities as high as 256 or even 512 gigabytes in the not-so-distant future! But... Pushing performance past existing boundaries into new territory would be for nothing if it wasnt reliable...

And thats where DDR4 actually makes some of its most significant improvements. With improved cyclic redundancy checks, on-chip parity detection of command and address transfers, as well as enhanced signal integrity, DDR4 is the most reliable DDR yet. Which leads into Kingstons HyperX Predator modules. Their performance is pre-optimized for you.

Key in one setting to turn on the XMP profile and its off to the races. Theyre optimized for Intels latest X99 platform so theyre a perfect match for your new core i7 6 core or 8 core CPU. And finally they have HyperXs signature tall heatsink inb lack so theyll complement any X99 motherboard perfectly. Thanks for watching this video about DDR4 technology.
