DDR4 vs DDR3 with Linus Tech Tips

Linus breaks down the benefits of DDR4 memory. Increased speed, better reliability and power efficiency are just a few of the significant improvements you can find with a DDR4 upgrade.

DDR4 is the latest step forward for synchronous DRAM which is the memory technology found in desktop or notebook computer or game console, as well as servers that power websites and services like Facebook or Dropbox.

Physical Features

DDR4 modules don’t look different at a glance but there are some subtle differences. DDR4 RAM is not backwards compatible with DDR3 motherboards and vice versa. The notch has been moved to prevent accidental insertion of the wrong type of memory. Instead of 240 pins, each module features 288 pins. And to improve strength and electrical contact there is slight curve in the shape of the bottom of the PCB.

Faster Speeds

As far as the technological differences DDR4 has faster speeds, starting 2133MHz, which would be fairly high end for DDR3. Planned speed increases that could take it well beyond 3200MHz!

Reduced Power Consumption

DDR4 is more efficient that DDR3, consuming up to 40% less power, requiring only 1.2V per module. This is a great benefit for notebooks, providing longer battery life.

Increased Capacity

Memory capacity of DDR4’s support for higher density chips and stacking technologies that may allow for single memory modules with capacities as high 512GB.

Improved Reliability

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.

Compatible with Intel X99 motherboards

HyperX Predator memory modules’ performance is pre-optimized when you select the XMP profile. Their optimized for Intel’s X99 platform which feature core i7 6 core or 8 core CPUs. The HyperX’s signature tall, black heatsink complements any X99 motherboard perfectly.
