Introduction

Intel introduced the consumer market to DDR4 with the introduction of the X99 platform. These are the early days of DDR4, and top kits are in the 3300MHz range, which is quite modest considering DDR4 is projected to be at 4000MHz+ in the near future. Nevertheless, DDR4 kits are pricey, and as with anything that costs you a kidney, it is good practice to get to know your purchase inside and out.

At launch, there wasn't even standardized support for memory dividers above 26.66x, and many have taken to using BCLK dividers to achieve the rated speeds of their kits. DDR4 isn't overly complicated, and overclocking DDR4 is basically the same as overclocking DDR3. There are some interesting new changes that come with the new standard, and I will cover those today.

In the slide above, you will notice that most of DDR4's advantages over DDR3 come in the form of power savings. For starters, the main DDR voltage is now 1.2v stock versus 1.5v with DDR3. A new voltage called VPP was also introduced; VPP is the voltage for the electrical high for DRAM row access.

For DDR4, JEDEC decided to introduce an external VRM that provides a 2.5v electrical high voltage for the word line (row access). Since the word line voltage is no longer pumped up from the DDR voltage (like it was for DDR3), the inefficiencies of pumping up the DDR voltage are gone, and instead you get power savings.
