We are using the MSI Z77A-G45 motherboard with the latest bios. This motherboard is ideal as a partner for this memory, as it costs only £104.99 inc vat today.
The MSI Z77A G45 posted with the memory at 1,333mhz, a safe figure for a first post. The secondary XMP profile is set up at 2,133mhz with timings of 11-12-11-30 @ 1.6V. Not the tightest timings we have seen, but acceptable for the speed.
The primary XMP profile sets the memory to 2,400mhz with timings of 11-13-13-30 @ 1.65V. Kingston have loosened the timings significantly to get the 2,400mhz speeds. Overclocking this memory wasn't massively successful, we managed to get a 2,524mhz overclock with timings of [email protected]. The end result didn't reap any noticeable rewards, so we test today with XMP profile 1, as the majority of people will do who buy it.
