14 DDR4 memory kits of 8 to 32 GB review: DDR4 for everyone

Faster memory has its perks, to a certain extent


Test results: max. OC with higher voltage and optimal timings

Lastly we take a look at the maximum overclocking potential. The Kingston HyperX Predator 3000 MHz CL15 quad-kit achieves the highest speed of 4133 MHz, however we had to reduce the timings to CL17-19-19-38. The 4000 MHz of the G.Skill Trident Z 3200 MHz CL14 might even be the most impressive feat, since we were able to lower the timings to CL12-12-12-34 on this kit. If we look at the performance tests, it stands out as the unequivocal winner. The memory bandwidth increased to 53 GB/s, compared to the 47 GB/s on standard settings.

We didn't get very far on some memory modules by upping the voltage. In some cases more voltage was possible, however it actually decreased performance. We used the settings that offered the best performance in all cases. The test results also nicely illustrate the dependence on the silicon lottery: the Kingston HyperX Predator 3333 MHz turns out to overclock much worse than the cheaper 3000 MH-kit from the same series. A bit of luck is required to achieve high speeds.
