Overclocking
When overclocking memory, it can be done in a variety of ways including increasing the frequency, slackening timings and changing the relevant voltages. Of course, a combination of these measures can also be done to get the very best performance. When we overclock memory in our reviews we go for all-out frequency. This is primarily done by tweaking the DRAM frequency within the BIOS. To do this, we take the default clock speed, which we set based on the JEDEC profile, or via XMP if the memory modules allow it, and then increase the DRAM frequency step by step while keeping timings and voltages the same as per the JEDEC or XMP profile. Once we increase the frequency, we boot into Windows and test stability using AIDA64’s built-in memory benchmark test. If the overclock is stable, we boot back into the BIOS and further increase the frequency of the modules and re-test for stability.
The highest we managed to get the kit was to 5333MHz, not too much overclocking, but it does give is a decent improvement over the base XMP speeds.
As you would expect, the results improve in every instance with overclocking. The improvements are just small and wouldn’t be very easy to notice on smaller workloads, but could stack up to a noticeable difference in certain tasks.
