This easy comprehensive guide illustrated with images is for the overclocking DDR4 using several brands such as Corsair and G.Skill with different IC's as an example. This guide is to supplement existing DDR4 overclocking guides whos knowledge was combined with the experience of overclocking the various DDR4 kits listed below(more to come).

Listed below are the specs of the motherboards, DDR4 kits and CPUs.

HisEvilnes:

  • Motherboard: ASUS Maximus Hero XI Z390.
  • CPU: Intel 8086K.
  • DDR4: CMT32GX4M4C3466C16, single-rank Samsung B-die.
  • Topology: T-Topology based on motherboard QVL.

Nanogenesis:

  • Motherboard: Asrock Fatal1ty Z370 Gaming K6.
  • CPU: Intel 8700K.
  • DDR4: BLS16G4D32AESB.M16FE, dual-rank Micron E-die.
  • Topology: T-Topology based on motherboard QVL.

There are several programs you need for stability testing, benchmarking, verification and a readout of your RAM IC's and PCB.

Dual rank 2x vs Dual Rank 4x.

When purchasing a DDR4 RAM kit to consider is your capacity in GB as well as how many DIMMs it will populate. For overclocking a DDR4 kit of 2 is best however if you need more or just want more capacity with 32GB or more you can either end up with a 4 x 8GB kit or a 2 x 16GB kit. Most consumer CPU's will support dual rank like the Intel 9900k and the AMD 3600X. This means if you use more then 2 DDR4 sticks you will share each channel. This will put more stress on the internal CPU IMC(Internal Memory Controller). Thus for extreme overclocking, Dual Rank DDR4 kits are better. When using Dual Rank kits make sure you populate the 2nd and 4th DIMM slots or reference the motherboard manual.

Another consideration to make when using 4 DIMM slots on dual-channel motherboards is the topology of the motherboard traces. The traces leading to your DIMM slots van either be Daisy chained or use T-Topology. This is however not commonly advertised to guesstimate check the motherboard QVL. When the highest validation on the motherboard for RAM is with a kit of 4 then most likely that motherboard is using T-Topology. If the motherboard highest validation on the motherboard for RAM is with a kit of 2 stick then it is most likely Daisy chained. This is also a good indication of the motherboard quality. Even when using a RAM kit of 2 sticks T-Topology is better for extreme overclocking(4000mhz or higher). But again for extreme overclocking it is always better to use 2 sticks of RAM on dual-channel for the best result.
