The pre-programmed timings and frequencies can be also found by using AIDA64:
Crucial has certified this piece of kit at 2666MHz with latencies of 16-18-18-38, while running at 1.2V. As with every kit we have tried out in the past, we have also went ahead and overclocked it further, first to 2800MHz; the tests ran fine with the stock timings and we did not need to raise the voltage either. The next step was 3000MHz, and we got full stability by altering the timings to 18-21-21-43 and upping the voltage:
Validation
The next step was 3100MHz, where we did also need to alter the timings to 19-21-21-45 at 1.35V:
Validation
We went even further at 3200MHz with the 20-22-22-46 timings at 1.35V; Memtest passed successfully:
Validation
Without increasing the voltage further, we were not able to climb up to the next frequency step.
Starting with the JEDEC 2133MHz, we did benchmark the RAM step-by-step up to 3333MHz, in order for you to spot the performance differences.
