Test System

Testing Rated Speeds

Enabling XMP boosted memory speed to 3200 MHz from 2133 MHz without any problems. My ASUS motherboard also adjusted voltages as it thought it had to. CPU speed remained at stock levels, matched with a performance profile the motherboard's BIOS offers as an option when you enable XMP. I pick this option for all tested memory sticks.


Overclocking these sticks was hard. I tried to both increase the voltage and loosen the timings, but failed to reach the next divider at 3333 MHz. So I went back to the XMP profile and adjusted timings to be as tight as they would go and managed to get 16-16-16-38 instead of 16-18-18-38. It seems as though there might still be some overhead to these sticks, but perhaps my CPU is not capable. I did use these overclocked settings with the "default" 1.35V DIMM voltage setting for nearly a week without any problems at all, no matter whether I played games, rendered videos, or just browsed the web. I also did not turn this system off while testing overclocks; I let it go to sleep and woke it up when I had to the next morning. Lower latency is nice for sure, but complete and utter stability is an ultimate requirement.
