We are using the ASRock Z87 OC Formula motherboard to test today's memory kit. It supports RAM from many manufacturers and gives us a large amount of flexibility to tinker with memory multiplier, base clock and timings settings. It has also reached the highest DRAM frequency of all the Z87 motherboards that we have tested.
Our full review of the ASRock Z87 OC Formula motherboard can be read here.
The fully-functioning XMP profile configured the memory kit for use at its 2800MHz frequency and correct timings.
Kingston includes a secondary XMP profile which operates at 2666MHz with tighter timings. This profile may be of interest to users with older processors that don't feature an IMC as strong as Haswell's, such as those from the Ivy Bridge series.
Windows and CPU-Z registered the memory's functioning settings as correct.
Our system's CPU-Z validation running at a 2800MHz DRAM frequency can be found here.
Great review Luke, but I do have a little disagreement over the oversized heatspreaders. there is never any need for these – a good airflow case is more than enough. Green PCB is a bad move too as you say,
They cause so many issues with CPU coolers.
