Overclocking
Disclaimer: Overclocking is never guaranteed, so the results may vary depending on certain conditions and various hardware configurations. I am not recommending overclocking if you do not know what are you doing. High voltages may damage hardware and it will not be covered by warranty.
Overclocking tests have been performed on the same motherboard as all other tests in this review so the C7Z370-CG-IW from SuperO.
We were not able to tighten the timings much at XMP speed of DDR4-3600. However, we were able to lower the CL from 19 to 16 what is still a good result considering that all was at the standard voltage of 1.35V. We could lower it to 15 but at higher voltage and test results were about as good.
Here is AIDA64 window which is showing expected bandwidth at above settings.
While trying to reach maximum frequency we couldn’t pass DDR4-3866. I’m not sure if it’s motherboard or memory limit but it’s still not bad result. Most users won’t really need so high memory clock.
DDR4-3866 was possible at more relaxed timings of 20-20-20-40 but still at 1.35V. Higher voltage wasn’t helping much in tightening the timings. When we look at XMP profile then it’s also not bad. We went from DDR4-3600 to DDR4-3866 while setting +1 to each timing.
Results at DDR4-3866 are better but also not so much better to overclock this memory at all cost. I guess that gamers can enjoy this memory at XMP settings and won’t really need to change anything in BIOS.
On the other hand overclockers and computer enthusiasts who are looking for top speed memory which is overclocking up to DDR4-4000 and higher, better look at higher TridentZ/TridentZ RGB memory kits.
