The pre-programmed timings and frequencies can be also found by using AIDA64:
After powering up the system, we loaded the default XMP profile of this RAM kit which set the timings at 15-15-15-35, with the speed at 2666MHz, while the modules were running at 1.2V. To make sure everything is in order, we also did run Memtest86 (four instances, 2GB RAM each) and no errors were thrown out. We then clocked the RAM higher, at 2700 MHz while using the 15-15-15-36 timings and the stability tests passed fine; 2800MHz with 16-16-16-37 was next and finally we went for 2900MHz which we could stabilize at 17-17-17-39 and using the same 1.2V:
We could not do 2933MHz by either raising the voltage or altering the timings further, but we think that 2900MHz is a decent overclock versus the stock speed.

Starting with the JEDEC 2133MHz, we did benchmark the RAM step-by-step up to 2900MHz, in order for you to spot the performance differences.
