The F4-3000C15D-32GVR 32GB DDR4 memory kit from G.SKILL does come with a rated speed of 3000MHz and is composed of two 16GB modules; since we are talking about overclocking modules, these also feature a custom designed heatsink of 42mm height so compatibility should not be an issue even with more massive CPU coolers.
CPU: Intel I5 6600K Retail
CPU Cooler: Antec Kuhler 620
Motherboard: Gigabyte Z170X-SoC Force
RAM: Currently tested kit
Video: HIS 380X
Power Supply: Cooler Master 850W
SSD: OCZ Vector 150
Case: Cooler Master ATCS 840
The pre-programmed timings and frequencies can be also found by using AIDA64. SK Hynix RAM chips are confirmed:
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 3000MHz, while the modules ran at 1.35V. 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 3200 MHz while keeping the timings the same along with the voltage; since we have received errors in Memtest86, we have decided to increase the timings and succeeded to obtain full stability.
3300MHz was not possible with our sample even when we have tried to relax the timings further. Here is the validation at 3200MHz too:

Starting with the JEDEC 2133MHz, we did benchmark the RAM step-by-step up to 3200MHz, in order for you to spot the performance differences.
