  • 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 don’t own like the servers that power websites

  • and services like Facebook or Dropbox.

  • Physically a DDR4 module probably won’t 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 there’s a slight curve in the shape of the bottom of the PCB.

  • So nothing ground breaking... No, it’s what’s UNDER the hood that’s interesting.

  • So what does this new fourth generation DDR bring that the previous oneDDR3 – didn’t?

  • Actually more than you’d think.

  • First up is improved SPEED.

  • Thanks for that.

  • DDR4 STARTS at 2133MHzwhich 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 twopower 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 let’s 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 bitsmemory capacity is poised to go through the roof

  • due to DDR4’s 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 wasn’t reliable...

  • and that’s where DDR4 actually makes some of its most significant improvements.

  • With improved cyclic redundancy checks, on-chip parity detection ofcommand and addresstransfers,

  • as well as enhanced signal integrity, DDR4 is the most reliable DDR yet.

  • Which leads into Kingston’s 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 Intel’s latest X99 platform so theyre a perfect match for your new core i7 6 core or 8 core CPU

  • and finally they have HyperX’s signature tall heatsink inb lack

  • so theyll complement any X99 motherboard perfectly.

  • Thanks for watching this video about DDR4 technology.
