  • DDR4 SDRAM, an abbreviation for double data rate fourth-generation synchronous dynamic random-access memory
  • type of synchronous dynamic random-access memory (SDRAM) with a high bandwidth(“double data rate”) interface
  • DDR4 SDRAM was released to the public market in Q2/3 2014
  • DDR4 is not compatible with any earlier type of random access memory (RAM)
  • DDR4 standard theoretically allows for DIMMs of up to 512 GiB in capacity, compared to DDR3’s theoretical maximum of 128 GiB per DIMM
  • DDR4 chips use a 1.2 Vsupply compared with the standard 1.5 V of DDR3 chips

Example 1: Corsair Vengeance LPX high-performance DDR4 memory

(Price: £76 @ 16GB)

Published on Aug 14, 2014
Vengeance LPX memory is designed for high-performance overclocking. The heatspreader is made of pure aluminum for faster heat dissipation, and the eight-layer PCB helps manage heat and provides superior overclocking headroom. The DDR4 form factor is optimized for the latest Intel X99 Series motherboards. Take advantage of the higher frequencies, greater bandwidth, and lower power consumption and enjoy the confidence of using genuine Corsair high-performance memory.corsair-vengeance-ddr4-2x16gb-large

Example 2: G.SKILL Trident Z DDR4 Memory

(Price: £105.53 @ 16GB)

Published on Sep 23, 2015
Built with only the best hand-picked components, the Trident Z is the highest tier of extreme performance memory kit on the planet.gskill-trident-ddr4How to Install DDR4 memory

Example 3: HyperX

(Price: £94 @ 16GB)

Before installing, check your X99 motherboard’s manual for optimal sockets for 2x or 4x module installation. Turn off the system and unplug the power cord. Locate the memory slots on the motherboard. Now, make sure the memory module notches are properly aligned with the slot on the board. Insert the HyperX DDR4 memory into the socket and press down firmly until you hear the clips snap into place. Now turn on your system and experience HyperX DDR4 performance.

DDR4 is next-generation memory designed to offer more power and less heat but DDR4 is not just a performance improvement. There are physical differences between this latest memory technology and DDR3 that you can see for yourself. The location of the notch is different, as is the pin count.
