Crucial CT4K8G4DFD8213 2133MHz 32GB DDR4 Review

We bumped up the DRAM voltage to 1.35V and maintained the timings at their 15-15-15-36-2T stock values for the overclocking testing. Our goal is to increase the motherboard dividers and see where Crucial's memory kit refuses to hold stability in the AIDA64 stress test.

The highest stable memory divider that we could reach was 2400MHz. We have seen many reports of this same kit reaching frequencies in the region of 2600MHz, however one specific stick in our set would not play nicely at 2600MHz or 2666MHz which resulted in only 24GB being seen by the OS.

A small frequency boost to 2400MHz is a decent result on a value-orientated set of memory. The result also highlights how Crucial's binning process is likely to be screening out the higher-frequency memory chips for use on the vendor's Ballistix series modules.

Overclocking Crucial's memory via a simple voltage boost and DRAM ratio bump yields some minor performance gains.
